Stellar Lumens vs Other Cryptocurrencies • Lumens vs. Bitcoin: Jed McCaleb spoke at Distributed Markets in 2017 about the advantages, but more importantly, the disadvantages of Bitcoin. Listen to the talk here. Jed said, “Bitcoin is this awesome innovation. The first thing it does is converts a real world resource, electricity, into a digital asset. So it takes something from the real world and puts it into the digital realm. The second thing it does is provides immutable public record. It’s basically a database that everyone can see but no one change arbitrarily… That’s great, Bitcoin solves the double spin problem [ of proving possession and transmitting volume]… [However, to fix the problems of bitcoin] you might think well maybe we’ll just kind of keep adding [software] to Bitcoin until we get there, but that’s not really the way software works. You want to have the design from the beginning and solve these simple issues. Bitcoin was designed to be a new currency, it wasn’t really designed to be this unifying universal payment network. So that’s what Stellar does. It solves these three remaining issues.” • Lumens vs. Bitcoin #2: According to wired.com, "Bitcoin mining guzzles energy - and it's carbon footprint just keeps growing." Wired says "Today, each bitcoin transaction requires the same amount of energy used to power nine homes in the US for one day... The total energy use of this web of hardware is huge—an estimated 31 terawatt-hours per year. More than 150 individual countries in the world consume less energy annually. And that power-hungry network is currently increasing its energy use every day by about 450 gigawatt-hours, roughly the same amount of electricity the entire country of Haiti uses in a year." Because Stellar is based on a consensus algorithm rather than mining, it takes much less energy to run the Stellar network. The Poseidon Foundation decided to build their platform on Stellar rather than Ethereum or Bitcoin because of this (twitter source). • Lumens ICO tokens vs. Ethereum ICO tokens: According to Stellar.org, "traditionally, ICO tokens have been issued on the Ethereum network in the form of ERC20 tokens. ERC20 tokens are easy to issue and are infinitely customizable using Ethereum’s smart contracting language. However, recent events have highlighted and exacerbated some weaknesses of the network, including slow transaction processing times for the network during ICOs and increasingly expensive gas prices (by fiat standards) for transactions and smart contract execution. Moreover, many organizations require only basic tokens; they adopt the risk of Ethereum’s Turing complete programming language without taking advantage of many of its benefits." "While Ethereum has the most expressive programming capabilities, we believe Stellar is the best choice for ICOs that do not require complex smart contracts. Stellar’s primary goal is to facilitate issuing and trading tokens, especially those tied to legal commitments by known organizations, such as claims on real-world assets or fiat currency." • Stellar vs. Ethereum #2: The median transaction time on Stellar is 5 seconds, compared to approximately 3.5 minutes on Ethereum (source). Stellar has a negligible transaction fee (.00001 XLM ~= $0.0000002) with no gas fee for computation, while depending on the complexity of the computation, the median cost for a transfer on the Ethereum network is $0.094. Security: While both Stellar and Ethereum run on a decentralized network, the Stellar network has fewer security pitfalls. Stellar uses atomic transactions comprised of simple, declarative operations while Ethereum uses turing complete programming capabilities which produces less auditable code and greater risk of exploitable vulnerabilities(source). Recently, a security flaw in the Ethereum network froze millions of dollars. According to Mobius ariticle written by David Gobaud, "On November 6, 2017, Github user deveps199 'accidentally' triggered a bug in Parity, a popular Ethereum mult-sig wallet, that froze more than $152 million in Ether across 151 addresses. The bug impacted several token sales including Polkadot, which has had ~$98 million out of its recent $145 million sale frozen." "Mobius had none of its ongoing pre-sale Ether frozen because we do not trust Ethereum’s Smart Contract based multi-sig wallets given the vast Turing complete attack surface and did not use one. Security broadly is one of the main reasons the MOBI token that powers the DApp Store is a Stellar Protocol token and not an Ethereum token." • Lumens vs. Ripple: According to Wall Street Bitcoin Exchange, "Many investors like to compare the company [Stellar] to Ripple, and there are a lot of similarities, being that some of the founders worked on the Ripple team. In what can now be looked at as another blockchain development drama that plays out on chat boards and in interviews all across the globe. Stellar declared they fixed Ripple’s problems with their hard fork, however, Ripple has failed to admit to any of the flaws in its design that the Stellar team has pointed out." The article concludes by saying, "We Choose XLM Over XRP For 2018. That is why we are going with Stellar Lumens over Ripple in our portfolio for the rest of 2017 and 2018. After holding Ripple for a long time this year, it just never seems to make the big break like other names with bigger market caps like Bitcoin Cash, Dash, and Litecoin have. While we are holding on most all our larger market caps, we feel that Stellar Lumens will be one of the break out coins for 2018." . . Conclusion The stellar.org team is doing an amazing job making partnerships and pioneering the use of blockchain technology for various types of transactions. What we are seeing is a new technology that can actually be used to solve real-world problems. As a community, we need to continue supporting Stellar and we will quickly see it power transactions across the world. What are your thoughts about Stellar? What do you see in the future of Stellar?

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.
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.
Core Features:
Multi-Device – Ability to hide accounts from all but the primary account.
Multi-Account – Multiple, entirely separate accounts in one wallet.
Multi-Platform – Available on iOS, Android, Web, Windows, Linux and Mac OS
Multi-Signature – Create multi-signature accounts between many people, where a certain amount of people’s signatures is required to sign a transaction. Some can be required before a transaction is signed.
Native support for many currencies – Multiple currencies are supported, accessed all from the same wallet and backup keywords.
Advanced Coin Control (Choose which UTXO are involved in the transaction), multiple destinations and manual fee settings.
2FA support for enhanced security, also available via Telegram.
Wrong-Currency detection. The server knows if someone sends BTC to a BCH address and visa versa and automatically creates a new account to be able to recover the funds.
A single backup using standard BIP39 mnemonics is valid and enough for an unlimited number of transactions, address and different account types
Safer than ever! Desktop Light Wallet - Anonymous and fast!
With Guarda Multi-currency Desktop Light Wallet you don’t need to register. Guarda has no access to your private keys or funds. You can receive, send, store, buy and exchange cryptocurrencies in complete anonymity and safety. All these features are available on Linux, Windows or MacOS. Choose the one that suits you!

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.
Huobi was founded in China and is now based in Singapore, with offices in Hong Kong, South Korea, Japan and the North America, currently sitting #3 in volume on Coinmarketcap. Huobi is a great leap forward for our growing presence in Asia and we are very excited to be listed here! You can find the official Huobi announcement here.
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.

Electrum-GRS is a lightweight "thin client" groestlcoin wallet Windows, MacOS and Linux based on a client-server protocol. Its main advantages over the original Groestlcoin client include support for multi-signature wallets and not requiring the download of the entire block chain.
Changes:
Qt GUI: seed word auto-complete during restore
performance improvements (wallet, and Qt GUI)
hardware wallets: show debug message during device scan
add regtest support (via --regtest flag)
other minor bugfixes and usability improvements
If present, libsecp256k1 is used to speed up elliptic curve operations. The library is bundled in the Windows, MacOS, and Android binaries. On Linux, it needs to be installed separately.
Transactions that are dropped from the mempool are kept in the wallet as 'local', and can be rebroadcast. Previously these transactions were deleted from the wallet.
The scriptSig and witness part of transaction inputs are no longer parsed, unless actually needed. The wallet will no longer display 'from' addresses corresponding to transaction inputs, except for its own inputs.
The partial transaction format has been incompatibly changed. This was needed as for partial transactions the scriptSig/witness has to be parsed, but for signed transactions we did not want to do the parsing. Users should make sure that all instances of Electrum-GRS they use to co-sign or offline sign, are updated together.
Signing of partial transactions created with online imported addresses wallets now supports significantly more setups. Previously only online p2pkh address + offline WIF was supported. Now the following setups are all supported: > online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline WIF, > online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline seed/xprv, > online {p2sh, p2wsh-p2sh, p2wsh}-multisig address + offline seeds/xprvs > (Potentially distributed among several different machines) Note that for the online address + offline HD secret case, you need the offline wallet to recognize the address (i.e. within gap limit). Having an xpub on the online machine is still the recommended setup, as this allows the online machine to generate new addresses on demand.
Segwit multisig for bip39 and hardware wallets is now enabled (both p2wsh-p2sh and native p2wsh).
Ledger: offline signing for segwit inputs (#3302) This has already worked for Trezor. Offline segwit signing can be combined with online imported addresses wallets.
Added Revealer plugin. ( https://revealer.cc ) Revealer is a seed phrase back-up solution. It allows you to create a cold, analog, multi-factor backup of your wallet seeds, or of any arbitrary secret. The Revealer utilizes a transparent plastic visual one time pad.
Fractional fee rates: the Qt GUI now displays fee rates with 0.1 gro/byte precision, and also allows this same resolution in the Send tab.
Hardware wallets: a "show address" button is now displayed in the Receive tab of the Qt GUI. (#4316)
Electrum-grs is a lightweight "thin client" groestlcoin wallet Android based on a client-server protocol. Its main advantages over the original Groestlcoin client include support for multi-signature wallets and not requiring the download of the entire block chain.
Changes
Android: fix some crashes
If present, libsecp256k1 is used to speed up elliptic curve operations. The library is bundled in the Windows, MacOS, and Android binaries. On Linux, it needs to be installed separately.
Two-factor authentication is available on Android. Note that this will only provide additional security if one time passwords are generated on a separate device.
Semi-automated crash reporting is implemented for Android.
Qt/Kivy: added "gro" as optional base unit.
Kivy GUI: significant performance improvements when displaying history and address list of large wallets; and transaction dialog of large transactions.
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.
Groestlcoin Sentinel is the easiest and fastest way to track/receive/watch payments in your offline Groestlcoin Wallets. Groestlcoin Sentinel is compatible with any standard Groestlcoin address, BIP44 XPUB (Extended Public Key) BIP49 YPUB and BIP84 ZPUB Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).

Stellar Lumens vs Other Cryptocurrencies • Lumens vs. Bitcoin: Jed McCaleb spoke at Distributed Markets in 2017 about the advantages, but more importantly, the disadvantages of Bitcoin. Listen to the talk here. Jed said, “Bitcoin is this awesome innovation. The first thing it does is converts a real world resource, electricity, into a digital asset. So it takes something from the real world and puts it into the digital realm. The second thing it does is provides immutable public record. It’s basically a database that everyone can see but no one change arbitrarily… That’s great, Bitcoin solves the double spin problem [ of proving possession and transmitting volume]… [However, to fix the problems of bitcoin] you might think well maybe we’ll just kind of keep adding [software] to Bitcoin until we get there, but that’s not really the way software works. You want to have the design from the beginning and solve these simple issues. Bitcoin was designed to be a new currency, it wasn’t really designed to be this unifying universal payment network. So that’s what Stellar does. It solves these three remaining issues.” • Lumens vs. Bitcoin #2: According to wired.com, "Bitcoin mining guzzles energy - and it's carbon footprint just keeps growing." Wired says "Today, each bitcoin transaction requires the same amount of energy used to power nine homes in the US for one day... The total energy use of this web of hardware is huge—an estimated 31 terawatt-hours per year. More than 150 individual countries in the world consume less energy annually. And that power-hungry network is currently increasing its energy use every day by about 450 gigawatt-hours, roughly the same amount of electricity the entire country of Haiti uses in a year." Because Stellar is based on a consensus algorithm rather than mining, it takes much less energy to run the Stellar network. The Poseidon Foundation decided to build their platform on Stellar rather than Ethereum or Bitcoin because of this (twitter source). • Lumens ICO tokens vs. Ethereum ICO tokens: According to Stellar.org, "traditionally, ICO tokens have been issued on the Ethereum network in the form of ERC20 tokens. ERC20 tokens are easy to issue and are infinitely customizable using Ethereum’s smart contracting language. However, recent events have highlighted and exacerbated some weaknesses of the network, including slow transaction processing times for the network during ICOs and increasingly expensive gas prices (by fiat standards) for transactions and smart contract execution. Moreover, many organizations require only basic tokens; they adopt the risk of Ethereum’s Turing complete programming language without taking advantage of many of its benefits." "While Ethereum has the most expressive programming capabilities, we believe Stellar is the best choice for ICOs that do not require complex smart contracts. Stellar’s primary goal is to facilitate issuing and trading tokens, especially those tied to legal commitments by known organizations, such as claims on real-world assets or fiat currency." • Stellar vs. Ethereum #2: The median transaction time on Stellar is 5 seconds, compared to approximately 3.5 minutes on Ethereum (source). Stellar has a negligible transaction fee (.00001 XLM ~= $0.0000002) with no gas fee for computation, while depending on the complexity of the computation, the median cost for a transfer on the Ethereum network is $0.094. Security: While both Stellar and Ethereum run on a decentralized network, the Stellar network has fewer security pitfalls. Stellar uses atomic transactions comprised of simple, declarative operations while Ethereum uses turing complete programming capabilities which produces less auditable code and greater risk of exploitable vulnerabilities(source). Recently, a security flaw in the Ethereum network froze millions of dollars. According to Mobius ariticle written by David Gobaud, "On November 6, 2017, Github user deveps199 'accidentally' triggered a bug in Parity, a popular Ethereum mult-sig wallet, that froze more than $152 million in Ether across 151 addresses. The bug impacted several token sales including Polkadot, which has had ~$98 million out of its recent $145 million sale frozen." "Mobius had none of its ongoing pre-sale Ether frozen because we do not trust Ethereum’s Smart Contract based multi-sig wallets given the vast Turing complete attack surface and did not use one. Security broadly is one of the main reasons the MOBI token that powers the DApp Store is a Stellar Protocol token and not an Ethereum token." • Lumens vs. Ripple: According to Wall Street Bitcoin Exchange, "Many investors like to compare the company [Stellar] to Ripple, and there are a lot of similarities, being that some of the founders worked on the Ripple team. In what can now be looked at as another blockchain development drama that plays out on chat boards and in interviews all across the globe. Stellar declared they fixed Ripple’s problems with their hard fork, however, Ripple has failed to admit to any of the flaws in its design that the Stellar team has pointed out." The article concludes by saying, "We Choose XLM Over XRP For 2018. That is why we are going with Stellar Lumens over Ripple in our portfolio for the rest of 2017 and 2018. After holding Ripple for a long time this year, it just never seems to make the big break like other names with bigger market caps like Bitcoin Cash, Dash, and Litecoin have. While we are holding on most all our larger market caps, we feel that Stellar Lumens will be one of the break out coins for 2018." . . Conclusion The stellar.org team is doing an amazing job making partnerships and pioneering the use of blockchain technology for various types of transactions. What we are seeing is a new technology that can actually be used to solve real-world problems. As a community, we need to continue supporting Stellar and we will quickly see it power transactions across the world. What are your thoughts about Stellar? What do you see in the future of Stellar?
