Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

What is Blockchain Financial?

Blockchain Financial is a set of web based services for individuals and companies that want to make things happen with the Cryptocurrencies Ecosystem. - For those that don't know anything about cryptocurrencies, we offer tools that will let them receive, send and operate with an assortment of coins. - For those that are already riding the wave, we offer tools that will let them do all those things that they weren't able to do.

Blockchain Financials mission

We're not here to reinvent the wheel. We're here to make it run smoother for you, and we provide some of the most useful services you'll find on the internet, made in a way that is easy to understand and use on a daily basis. In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

Substratum leads Round 2 of Monthly Community Voting Round - AMA Transcript Inside!

Hey guys, If you haven’t noticed on Binance’s monthly community voting round – it has been a tight battle but Substratum has been taking the lead.
I wanted to explain why Substratum has seemingly come out of no-where but has garnered some attention. Substratum is creating a solution to a very big obstacle in the world web. The below has been taken from Justin Tabb aka the Founder of Substratum and summarises what the purpose of the network is.
I hope you guys can support their vision by voting for Substratum (SUB) on the https://www.binance.com/vote.html.
The Substratum Network will bring the decentralized web worldwide without the need of special software for the average internet user. We will be able to serve Substratum Requests directly to the default browser (Safari, Firefox, Chrome, Internet Explorer) without any special software installed on the average consuming users computer.
How Substratum Works
Ease of Use: currently nearly everything that has to do with crypto or the blockchain is very difficult to use and requires technical knowledge. Through our 10+ years of experience working with companies like Apple we understand the importance of a good user experience.
• The average internet user requires NO special software to use the Substratum Network. The default browser will service all requests for average users so they do not need to do ANYTHING different. Users who wish to service requests and receive SUB coins in return will have a point and click user interface that any user can setup. No technical knowledge required. SubstratumPay will be seamlessly integrated and geared towards high conversions of low technical expertise users. • Serving Up of Decentralized Content: Substratum provides a method for serving Decentralized Content (including Web Sites, Data, and Applications) through a Mac, Windows, and Linux application/service that is easy to install and run (requires no technical expertise) and serves up decentralized content using the toolkit that we have developed. This is a point and click process and requires zero technical knowledge. All the user has to do is install the application, click through a few settings and they are up and running and making Substratum Coin. Incentivizing Users to Serve the Content: in order to incentivize users to run the Substratum Network client on their machine we will be providing Substratum Coin to them for doing so. The coin is issued to the serving machine through a micro-transaction from the hosting site to the serving computer. By breaking fees down to a micro-transaction level this will greatly reduce the overall cost to companies and entities that want to host sites and applications on the internet solving yet another problem with the web as it stands today.
Privacy / Security / Encryption: by allowing millions of Substratum Network users to serve content the biggest concern becomes privacy and security. Substratum solves these issues through advanced cryptography algorithms rooted in Artificial Intelligence that ensures all data remains secure. Following the lead of BitCoin this is the strength of cryptocurrency and the crypto movement. Storage and Serving of Content: in order to serve millions of sites, databases, and applications the Substratum Network employs custom developed advanced compression algorithms and machine learning to geolocate the right Substratum Network machine to serve up the content to the appropriate user based on geolocation, this will ensure the fastest load time with the lowest amount of latency and strain on the Substratum Network and both the serving and receiving machine. DNS (Domain Name System): DNS or the Domain Name System is the system that currently tells your browser where to go when you type in a domain name. For instance when you go to Chrome and type in apple.com a DNS lookup is performed to check where to send that request, the DNS system comes back with an IP address and your request is routed there. In the first version of SubstratumDNS will be a complex, AI enabled DNS server that will receive DNS requests along with the geolocation of the requestor and find based off of that information the closest available SubstratumNode that is able to fulfill the request. Development Tools for the Decentralized Web: the Substratum Network will provide an API and SDK for developing tools on the Substratum Platform. This will bring in strong developer support and will accelerate the growth of the decentralized web on the Substratum Network. Net Neutrality: with the Substratum Network ALL web-sites and applications will have EQUAL ability to be broadcast in an equal and fair manner.
International Digital Barriers: currently countries like China have strict regulations on what their 1.379 billion citizens are able to interact with on the internet. Substratum will break down these barriers through a network of decentralized computers running the Substratum Network Software. Where other solutions that are currently used by residents in these countries require special software to be installed, like TOR, Substratum will take a reverse approach and require no special software for the average user.
High Hosting Costs: currently businesses must pay high hosting fees to get their web-sites on the internet. Amazon Web Services launched a 3.5BIL USD per year business by attempting to solve this problem. They allow you to pay for how many minutes you run a web / database server. Substratum completely solves this problem through the power of cryptocurrency by only charging for each request that is processed. You can check out the website here: • Substratum.net o And the whitepaper is available in multiple languages inclusive of Mandarin.
Furthermore, Substratum and the founders are very active in the slack – which they have recently hosted an AMA (ask me anything); I took the liberty of getting this information and if you are interested about the project to read more into it. Obviously they can’t reveal the inner workings of their product due to product sensitivity and being ahead of their competition but they are always up to date with the community through several videos on Youtube (https://www.youtube.com/channel/UCxUJoTH0XLERKl55zGnFI6g) and announcements through their social media. I recommend you follow them.
Q: Any major talks with exchanges yet? A: We just announced that we are launching on our FIRST official exchange of COSS.IO on 9/30 trading against BTC and ETH. More to follow.
Q: Will I be able to run a supernode? A: From the beginning NO. Supernodes will only be for Substratum; however, they will run the SAME software that are used to run a NODE. In time we will develop a requirement list to run a supernode. If you qualify you can then run a SuperNode and receive a premium payout
Q: Is it possible to show a few examples of SUB payouts you get from running a node, and the tell us the ratios that affect the amount/way to calculate it somehow? (SUB owned, for how long you've been running a node etc..) Or is that still in testing? What's the difference in node rewards from someone who has 0 SUB's as opposed to someone who has X amount of SUB's? A: So the calculations for this are in process; however, you can watch our video "How Substrate Per Request Is Calculated" on our YouTube channel for an idea of what variables go into each calculation
Q: How do we prevent DDoS? A: The first step is not talking about how we prevent DDoS or any other hack. We call that security through obscurity. :slightly_smiling_face: Secondly, one of the primary ways to prevent a DDoS attack is decentralization. Well that's perfect. Lastly, there are other techniques, like black-holing and basically shutting a node down. The great news is that we will be decentralized so we are only talking about a node or specific IP Address that will not disrupt the network. :thumbsup:
Q: Say i got a website i want to publish on Substratum, how does this process go? A: Just a shout out if you ask for a lot of detail regarding technology stack and how exactly something will work we are most likely going to give you general answers. This is not to skirt the question. We want to be 10 steps ahead of anyone with nefarious plans before we get launched. You will be seeing more on this very soon. You should be seeing a video drop on this in the next week or two. The goal is to make this easy to use and powerful, plus empower others to use the tools. We're looking at things to different ways one is towards the average user who just want something sitting on their system and doesn't need any more details and the other is a super user who wants a lot of configuration options.
Q: When more people will use Substratum and more will run nodes, the value of SUB will increase. How will it be calculated how much SUB you get as a reward for running a node as value increases? Will it be calculated by Substratum itself or will it be changed manually every so often? A: We will be calculating against the live value of Substratum
Q: Is substratum detectable, for example if it’s used in a country like china and they are caught on these sites that are blocked by government… Can it be detected? A: The goal is to make it constantly moving. We do not want it to be. fast, easy, powerful, anonymous.
Q: Will there be Master Nodes? A: We will have some services that are available that will help provision nodes into the network. We are still story mapping this flow and architecture.
Q: Could we get more information about what you require to do to be a beta tester? A: To be a beta tester you only need to add yourself to the #beta-tester channel here in Slack. You will be notified when we are ready for you to download and install and the process and requirements to continue to run the software
Q: Will you keep us informed on a at least weekly base to tell/ show us the progress made? A: Yes! We will continue to drop at least 2 professionally made update videos each week (with Jason Burns the guy who does them) and we will be doing more and more candid videos
Q: Who is the winner of 10k subs and what idea did he give? And what about 2nd place and 3rd place. A: To be announced shortly. The Substrate is reserved for the payout
Q: Can we mine Sub without the software? A: I will personally be selling pick-axes on my personal website "pixaxesforsale.biz" for a low cost of $19.99
Q: Unless they disclose intelligent life in space, people are still going to be mad at the end of this. A lot more will be happy though A: Haven't found intelligent life in space. Some would question finding it on earth.
Q: From a legal stand point How are we protected if someone is running illegal content on our Node? A: Take a look at our video of "How Substratum Secures Your Site Content". You will never hold the entire piece of data except perhaps in memory if you are the one serving the request so you could never be culpable. Amazon isn't held responsible if I host illegal content now
Q: What about content control? child porno .. and so on ... ? Is there anything to control the content or? A: Excellent question. This was a big concern for us. We do not want Substratum to become the dark web. The goal is to allow the community to self-govern, vote up and down, call out illegal activity. The utilities will allow those with bad intentions to be called out. The more we grow the better we will be about wiping out things like child porn, and just as bad human trafficking.
Q: When will the raised money going to be donated? A: We have already donated $10K out and we have a pending wire for $40K going out Monday. We are working to find the BEST places with the IMMEDIATE needs.
Q: When will the livestream of the burn be? A: Burn #1 will be a livestream of my computer screen later tonight. I will announce on twitter at least an hour ahead of time and we will record it so people can see it later
Q: What will the final circulating supply be after all three token burns? A: We are still getting a FINAL number on this, we are still doing some FINAL Bonus sends but we will have the number VERY VERY soon and we will be posting it. We will be burning 60MIL tokens tonight so that should give you some kind of an idea.
Q: can you stop slack from freezing my firefox? A: Use the downloadable app, or get better internet, or get a new computer. Sounds like a dumpster fire.
Q: Everyone brings up the obvious choice of child porno that needs to be dealt with via content control. What about grayzones such as weed-selling sites? Its illegal in some countries, some not. How will Substratum deal with these grey-zones? A: Give me liberty or give me death.
Q: Could i have an invite to beta test channel on slack? A: Yes, just let a moderator know.
Q: could i get more information on what beta testers are required to do? I will happily be one if it helps the process and I actually manage to do it. A: Join the #beta-testers channel here
Q: when will we see a new homepage? A: This is being worked on now!
Q: is there a minimum amount of SUB needed to run a node? A: NO! 0 Substrate, don't worry, you will have some soon once you turn it on
Q: What about running an "micronode" on any phone (there is a big % using phones all the time), I mean an app installed on phone to run a node and to host only small content like a photos... Did you think about of this? A: https://youtu.be/h6tZ_ZFuFmY
Q: What if my website ethically and morally right and people downvote it out of jealousy will my website be removed if there are more number of downvotes and my content is clean? A: The process is NOT that simple, we will release more details later but this is being taken into consideration. I answered in a bit more detail above as well
Q: Does the Sub team ever sleep ? A: Only when driving
Q: Can I run a node on a VPS? A: I certainly won't be telling people how or where to run the node software. Do the best you can. I actually answered the VPS question above too. We will have a command line version if that is the question. That you can run on something like Ubuntu Server if you want
Q: Can the voting system for all illegal stuff on the internet also be used in a 'bad' way on the regular websites to for example gain commercial/business advantages? A: It should not, no one will have 'master control' All control, so the market decides always.
Q: Who will profit from cryptopay? How will this bring value to SUB tokens? A: Everyone will as we gain dominance. But also, Substratum the company will take a small percentage. This will enable us to continue building awesome apps. CryptoPay will be the cornerstone of many good things to come. Think retail, goods and services.
Q: I work at a games company with 200+ high powered pcs. If I install sub nodes on every single one of them at night, will IT be able to catch and fire me A: See your HR manual, or HR supervisor for those questions.
Q: How do websites and hosters remain protected from hacking, if sites are created with innate vulnerabilities does that expose other sites hosted by the same node? A: This is a great question. Hosting Nodes will have to vet out their security. Again, being decentralized goes a long way in providing security. So does encryption. We will help hosts be the best hosts possible.
Q: Please explain the earning in SUB by running a node? A: So the SUB comes FROM the HOST (who purchases the SUB) to the NODE for the cost of the transaction. https://youtu.be/LWZ1DIGGOoQ
Q: When will the tokens be sent for the 100 Sub giveaway A: Shortly
Q: How will Substratum market themselves towards countries that needs SUB the most but are hard to reach, such as North Korea, Africa, China? A: Think spider web. The more that join, and use, the less it can be controlled.
Q: How long will this bear market last for? A: Let me put the fortune teller hat on. Crypto is a young demographic currently. It will be bear'ish until we make the technology easier and they get older.

New server trifecta: Public bitcoin node, electrum and electrum via tor hidden service with basic activity analysis.

I decided a few weeks ago to setup a new public server with a few goals in mind:
  1. Contribute back to the community
  2. Understand a bit better how the infrastructure of bitcoin and electrum (my client of choice) work
  3. Understand what information about our transactions are logged in the default configuration
  4. Do it all with bitcoin purchases
So, in the spirit of #1 above, here is what I have learned so far. Happy to be corrected if any of my conclusions or methods are a bit off.
Server setup
I found a good deal on a VPS from BoltVM that could be purchased using bitcoin. Having looked at the specs required (and suffered under under-resourced VPS configs before) I went perhaps a bit over the top w/ a 2CPU/2048GB/2TB/200GB system. Getting setup w/ bincoin purchase was fast and efficient and the system has performed quite well so far. Note: TOS forbids bitcoin mining, but I am only running a node, so hopefully no worries here.
DNS name was purchased via Namecheap for BTC. Process here was a bit strange as you had to first credit your account w/ USD via BTC then make your purchase. Whatever, it worked fine in the end.
Bitcoin node
I chose to run the standard bitcoind with most recent version of 0.10.0 deployed. The bitcoin node is registered both bitnodes.io, and connected to blockchain.info.
As of now, there are 6321 nodes contributing to the network according to bitnodes.io. The server has been running for 9 days and has sent out about 70Gb data with blockchain storage of about 37Gb and it runs about 80 connections most days.
I found that downloading 22Gb of blockchain bootstrap data via bittorrent was a far faster way of getting the node synced up. Even after this, it was another 6 hours or so until fully synced.
Electrum server
During most of the time that I have been using electrum there have been between 20-30 public servers available on the network. This is significantly fewer than bitcoin nodes and I was surprised at how few servers were out there for the number of users that it seems to have given the buzz here on /bitcoin.
Setup wasn't difficult... download source via git and a quick python deployment script. Edit config files to point to local bitcoin node and then fire it up. Point electrum at the server (still private at this point) and wonder why it isn't connecting while CPU utilization is maxed out. Started learning a bit more and found that the indexing cant take well over a week on a powerful system with massive i/o during this time. Luckily much like bitcoind you can download someone else's index set to bootstrap the system. The install script will do this, but just for an index of the last 100 blocks, but wanting to run a "full" 10,000 block node, I had to find an updated index here. It is 12Gb for either 100 or 10,000, so not sure why you wouldn't want to run the full set. So recommendation here is don't download the 100 index during the setup script and get the 10,000 one before startup (and editing the config file to change default 100 to 10,000). It is clear that the index time for a new server is only going to get longer over time and the reliance on getting boot strapped data might cause issues in the future. Imagine a bug discovered that trashes everyone's index db... it could be weeks before electrum clients were usable again.
Once the system was up stable and processing test bitcoin transactions, it was time to let the world know about it. Electrum server and clients find each other via a hardcoded freenode.net IRC channel #electrum. The devs hang out here as well. Once your electrum server is configured to log into IRC using a pre-registered nick it will login where a bot will check that your blockchain index is up to date and kick you if not. Clients look at this channel to find names and IP addresses of possible servers to connect to. Use of IRC does make for a distributed name service, but loss of control of the #electrum channel or the bot will break the electrum ecosystem quite quickly.
Finally Tor was setup with a hidden service pointing to the electrum SSL port. Unfortunately the IRC system doesn't allow for registration of onion addresses, so here is the first and only place so far you can find the address:
ubbnbro6gjafiebf.onion
Stats and analysis
So far the electrum server has been running publicly for 5 days. I have left the default logging on for the purpose of learning how the system operates. Relatively little information is logged by the system. Here is an example of a connection:
[05/03/2015-20:34:16] SSL xx.xx.xx.xx:64453 1 1.9.8
and here is a transaction:
[05/03/2015-11:57:40] sent tx: 411849c8351f2ffaf9f46f2e10d7d76d39f61b07a452c962a4e76556a0ba9619
That is pretty much it for logs maintained. While it would be possible to modify the source to log more, in the default setup there is relatively little information retained by the server (presumably by design).
In 5 days there have been 6155 unique SSL connections out of 6253 total. So most users randomly bounce from one server to another as intended so there is little correlation between one electrum session and another. There were also 106 unique TCP connections, which is a bit strange as it means that these users have intentionally chosen to turn off the default encryption on the client. Not really sure why the non-SSL port is offered by default and I have considered turning it off.
Most users are running either 1.9.8 or 2.0 versions of the client with a rapid uptake of 2.0. In last 2 days of 2.0 being available 1/3 of clients have already upgraded.
Client numbers Client Version
13 1.9
38 1.9.4
18 1.9.5
37 1.9.6
390 1.9.7
4464 1.9.8
1217 2.0
2 2.0-beta
37 2.0b2
22 2.0b3
~~If I am interpreting the log correctly, it seems that the majority of clients only query one address (note addresses aren't logged, just number of addresses requested). I am not fully confident in this analysis as it suggests most users own a single coin in one address only with no change addresses used yet. ~~
EDIT: As ThomasV1 points out the single subscription queries are clients using this server to confirm that their server of choice is up to date. So most clients have 1-19 addresses in their wallet with an interesting peak of ~10% of clients querying over 100 addresses.
Number Clients Address Subscriptions
5818 1
222 2-20
95 21-40
39 41-60
17 61-80
7 81-100
44 101-690
So far 90 transactions have been logged on the server. Pulling the output amounts from blockchain.info indicates that 491 BTC has passed through the server. Of course if you have a address with 20 BTC and you spend .005 BTC the outputs will be 20 BTC (your sold coin and your change) so this may wildly overestimate the actual amount of coin changing hands.
Note that I initially tried to do this analysis using blockchain.info data only via this page which suggested an amazing 4000 BTC (1 million USD!) in 56 transactions were first seen from my server. But since blockchain doesn't monitor all servers this is inflated highly as this isn't actually transactions originating at my server, but just where blockchain.info first saw the transaction on the network. Also they only have seen 56, and not all of the 90 that the logs indicate did originate on the server. So I find the IP based analysis by blockchain.info to be of dubious value and quite misleading.
Much needed TL/DR:
It took a bit of time for a highly experienced linux admin to setup a full public bitcoin node and electrum server. There can be considerable startup time to get the systems up to speed that can be avoided by bootstrapping. Electrum servers are relatively few in number and there are at least a few reasons that they could be taken offline.
Server can be found at electrum.fsck.space and ubbnbro6gjafiebf.onion. Check the console page for a donate address if you want to support the upkeep on another electrum server.

Enigmabox - First Impressions / Review

I am not affiliated with Verein Enigmabox. I am just a geek into meshnets.

Background

I'm an IT Security analyst with a interest in cryptography, cipherpunk, darknets, meshnets, and a lot more geeky things that are not worth mentioning. I only have 15000 characters in this text box! :-)
I run a hyperboria node VPS and a couple of raspberry pis that are peered with my small mesh so when I stumbled across the Enigmabox my interest was piqued.
The Enigmabox is a small embedded PC in red aluminum case with a silkscreen logo and writing. It has three Ethernet ports, and two USB ports, an RS-232 port, and a power connector.
It's administered via the web. Eth0 has a static IP of 192.168.100.1 and Eth1 has a static IP of 192.168.101.1. Eth2 is your public/ WAN port.
It can either be used as a CJDNS node or can connect up to a CJDNS-based VPN run by the folks at Enigmabox.
It costs €575.00 which includes one-year of VPN access. As of this writing you have a choice of VPN exit nodes in:
Enigmabox claims 40mbits of throughput, but on my 50/16 Comcast Business Cable connection I am getting 14/10 out the US endpoint.
The box is designed to be set up and used as the gateway for your computer, or for your entire network. I set mine up as the gateway for my entire network.
I had no problems last night watching Netflix or Hulu Plus on my Roku box. This was while several other high-bandwidth activities were also going on from other devices on my network.
This morning however I noticed that the internet connection dropped for the US endpoint so I had to switch to the German one. I'm not sure if that was a problem local to the VPN concentrator or if I actually got flagged and banned for excessive bandwidth usage.
Later on this afternoon I was able to switch back to the US endpoint which is good because my Company geoblocks network activity from pretty much every country's IP-space other than the US and Canada.

The Ordering Process

I found the ordering process to be a bit cumbersome and arcane to be honest. There were issues with the order form, and my only two payment options were bitcoins or wire transfer.
I would have felt much more comfortable spending €575.00 had I could have paid with either a credit card or hell — even PayPal!
On the plus side, I got to learn just how much more arcane and byzantine wiring money from one's credit union in the United States to a bank in Switzerland and converting the currency from USD to Euros could actually be.
I can't wait for BitCoin to become the de-factor currency for ecommerce, but I don't have hundreds of dollars or euros tied up in any online or offline wallet to have made that practical. And if I'm going to spend several (several) hundred dollars for an item call me crazy but I do like the consumer protections that my credit card affords me.
I placed my order on June 19th. I wired the funds on June 19th. My credit union told me the funds would be made available to the Enigmabox guys on July 2nd.
On July 3rd I inquired with the Enigmabox guys and asked them if they had received the funds wired and received a response that my order had already shipped.
On July 18th I inquired with Enigmabox again to inquire if there was a tracking number available and was told there was none and that I should just wait and be patient.
It was at this point that I really started to get a very bad feeling that I had just pissed-away several hundred euros and that I needed to prepare myself for the fact that I had been scammed.
I let the Enigmabox guys know this and also expressed how surprised I was that no tracking number was created and nor was the box insured. I wasn't only just talking about my protection, but what about the sellers' protection too?
This is like selling and shipping 101. You get a tracking number. You insure it. If the package had gotten lost in-transit, misdelivered, or if I was a scammer I could have simply said I never received it. There would have been no proof.
The package arrived yesterday and was delivered by my postal carrier.

The Contents of the Box

The box arrived with the following contents:
  • Enigmabox
  • USB Stick with X.509 certificates that I assume are my VPN credentials.
  • UK/EU style wall-wart power adapter
  • UK/EU wall-wart 220vAC outlet to US 115vAC outlet adapter
  • Ethernet Cable
  • Single sheet providing quick setup instructions
  • Grandstream VoIP Phone
  • UK/EU style wall-wart power adapter
  • UK/EU wall-wart 220vAC outlet to US 115vAC outlet adapter
  • Ethernet Cable
  • User Manual for VoIP Phone

Initial Setup

The initial setup was straight forward. Plug cablemodem into the Internet port. Plug LAN port into my switch.
DHCP assigned an IP address and local DNS.
Opened a web browser to http://box.enigmabox.net.

Thoughts and Issues

I found the Enigmabox to be very well constructed. The inclusion of adapters for US plugs was a welcome surprise.
The inclusion of a VoIP phone I found to be excessive. It would make much more sense to lower the price a bit and let the end-user supply their own phone.
Surfing the net has been painless and everything just works.
No ports are exposed on the Enigmabox to the Internet and the box itself is running a stripped-down version of Linux. The root shell was ash which was nice surprise. I was expecting busybox to be honest.

Pros

The box and project seem pretty mature and well thought out. The VPN service seems solid for the most part, and it has held up to some bandwidth intensive applications.
I'm not a gamer so I can't describe lag times.
The software comes with an embedded version of Asterisk to facilitate the VoIP communication, a mini- webserver, DokuWiki (which I applaud their choice there!), an Email server, roundcube webmail, and a twitter-like clone.

Cons

The ordering process leaves a LOT to be desired.
Limited payment options could be a deterrent to some customers.
The fact that the device and box was shipped with no insurance and no tracking is ludicrous.
Documentation is non-existent. The online wiki/ FAQ is incomplete.
And there is no support. No forum. No mailing list.
I've got some questions about some of the config options and some things I'm seeing and experiencing and I have no idea who to ask for thoughts or suggestions.

Conclusion

Is it worth €575? No. But it's also worth noting that of that €575, about 1/3 of that is for one year of VPN service.
It's like €132 for the year (or maybe that was $132). Even that is a bit over priced especially when Private Internet Access is $40 for the year.
But I get that there's economies of scale and that hopefully that price will come down. After all, 132 a year is only 11 a month, and that's not that unreasonable when you look at things that way.
My suggestion? Get yourself a RaspberryPi or a BananaPi and build your own.
And sign up for the VPN access to help support the project.
It's a cool project.
Now if only I could figure out how to connect up to some hyperboria sites. :-) I'm peered with a couple of nodes on hyperboria but nothing is loading. Hell, I can't even load any of the hypesites that are part of the Enigmabox network.
Time to fork the code on github and start reading!
Cheers.
Edit: A word here and there.

Bitcoin-QT 0.9 disponível para download

The Core Developers of Bitcoin released the 0.9.0 FINAL of Bitcoin Core (aka Bitcoin QT).
DOWNLOAD:
This is a Final Version, but its the same as 0.9.0rc3
Sources: https://github.com/bitcoin/bitcoin/releases http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.9.0/ https://bitcoin.org/bin/0.9.0/README.txt
Bitcoin Core version 0.9.0 is now available from:
https://bitcoin.org/bin/0.9.0/
This is a release candidate for a new major version. A major version brings both new features and bug fixes.
Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), uninstall all earlier versions of Bitcoin, then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
If you are upgrading from version 0.7.2 or earlier, the first time you run 0.9.0 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine.
On Windows, do not forget to uninstall all earlier versions of the Bitcoin client first, especially if you are switching to the 64-bit version.

Windows 64-bit installer

New in 0.9.0 is the Windows 64-bit version of the client. There have been frequent reports of users running out of virtual memory on 32-bit systems during the initial sync. Because of this it is recommended to install the 64-bit version if your system supports it.
NOTE: Release candidate 2 Windows binaries are not code-signed; use PGP and the SHA256SUMS.asc file to make sure your binaries are correct. In the final 0.9.0 release, Windows setup.exe binaries will be code-signed.

OSX 10.5 / 32-bit no longer supported

0.9.0 drops support for older Macs. The minimum requirements are now: * A 64-bit-capable CPU (see http://support.apple.com/kb/ht3696); * Mac OS 10.6 or later (see https://support.apple.com/kb/ht1633).

Downgrading warnings

The 'chainstate' for this release is not always compatible with previous releases, so if you run 0.9 and then decide to switch back to a 0.8.x release you might get a blockchain validation error when starting the old release (due to 'pruned outputs' being omitted from the index of unspent transaction outputs).
Running the old release with the -reindex option will rebuild the chainstate data structures and correct the problem.
Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan the blockchain for missing spent coins, which will take a long time (tens of minutes on a typical machine).

Rebranding to Bitcoin Core

To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we have renamed the reference client to Bitcoin Core.

Autotools build system

For 0.9.0 we switched to an autotools-based build system instead of individual (q)makefiles.
Using the standard "./autogen.sh; ./configure; make" to build Bitcoin-Qt and bitcoind makes it easier for experienced open source developers to contribute to the project.
Be sure to check doc/build-*.md for your platform before building from source.

Bitcoin-cli

Another change in the 0.9 release is moving away from the bitcoind executable functioning both as a server and as a RPC client. The RPC client functionality ("tell the running bitcoin daemon to do THIS") was split into a separate executable, 'bitcoin-cli'. The RPC client code will eventually be removed from bitcoind, but will be kept for backwards compatibility for a release or two.

walletpassphrase RPC

The behavior of the walletpassphrase RPC when the wallet is already unlocked has changed between 0.8 and 0.9.
The 0.8 behavior of walletpassphrase is to fail when the wallet is already unlocked:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 Error: Wallet is already unlocked (old unlock time stays) 
The new behavior of walletpassphrase is to set a new unlock time overriding the old one:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 walletunlocktime = now + 10 (overriding the old unlock time) 

Transaction malleability-related fixes

This release contains a few fixes for transaction ID (TXID) malleability issues:

Transaction Fees

This release drops the default fee required to relay transactions across the network and for miners to consider the transaction in their blocks to 0.01mBTC per kilobyte.
Note that getting a transaction relayed across the network does NOT guarantee that the transaction will be accepted by a miner; by default, miners fill their blocks with 50 kilobytes of high-priority transactions, and then with 700 kilobytes of the highest-fee-per-kilobyte transactions.
The minimum relay/mining fee-per-kilobyte may be changed with the minrelaytxfee option. Note that previous releases incorrectly used the mintxfee setting to determine which low-priority transactions should be considered for inclusion in blocks.
The wallet code still uses a default fee for low-priority transactions of 0.1mBTC per kilobyte. During periods of heavy transaction volume, even this fee may not be enough to get transactions confirmed quickly; the mintxfee option may be used to override the default.

0.9.0 Release notes
