Ethereum byzantium release date
They gave their clients the option to downgrade to pre-upgrade versions of their Ethereum-based platforms but firmly recommended against it. The developers decided to postpone activating the Constantinople hard fork until sometime between February 26th and 28th in Petersburg which was launched along with Constantinople disables the part of Constantinople's code that unintentionally created major security issues, as well as reducing the reward for mining on the Ethereum blockchain from 3 ETH to 2, just as the previous hard fork Byzantium reduced the mining reward from 5 ETH to 3.
The upgrade will implement four out of the five originally-planned upgrades based on the EIPs announced in October Core Ethereum developers told Coindesk at the time that the process of developing and implementing the upgrade had "dragged on long enough," and that developers were eager to work on other projects related to Ethereum.
The upgrade is designed to delay a looming difficulty bomb embedded in the Istanbul upgrade. It was activated at Block number 9,,, implementing only the EIP , an upgrade that delays Ethereum's "difficulty bomb. This was the third time the difficulty bomb was delayed.
Part of the fork enabled both Constantinople and St. Hancock told Coindesk that "for Ethereum to be sound money, it needs to be very conservative in making changes The biggest differences between it and previous Ethereum upgrades is that Serenity will work off of a proof of stake mechanism and what Ethereum developers call "shard chains. After the 2. ETH 2. Part of the reason for this is that creating a systemwide upgrade that uses shard chains - a "multi-client approach" - takes much longer than Ethereum developers anticipated, according to Serenity project lead Danny Ryan.
This fork was caused by a bug previously implemented by Ethereum developers, in part to upgrade Go Ethereum commonly referred to as "Geth" , but also to, ironically, prevent the exact kind of bug it caused. Securities and Exchange Commission SEC published an investigative report about the collapse of the Ether-funded DAO without bringing enforcement action against any involved parties.
The report provides a thorough description of the establishment and organization of the DAO and notes that by doing business with U. It found that the DAO tokens would be securities under the Howey test and that they should have been registered and offered pursuant to the Commission's regulations unless they were eligible for exemption. In addition, the Commission indicated that platforms where the DAO tokens were traded probably should have been registered as securities exchanges or other regulated facilities unless there were relevant exemptions available.
Unlike bitcoin, which was determined to be a commodity because it held no pre-launch ICO , Ethereum's blockchain network was funded through a presale of Ether. Also, following the sale, there was no single, central enterprise being invested in, which complicates the question of how to classify Ether. It also gave three methods members of the public could use to deliver their comments to the Commission, including a mailing address and a link to its public comments website. By October 12, the exchange's ether futures contract had attracted scant trading volume.
In September , Ethereum "futures" contracts traded at record levels of volume. Mining on the old Ethereum blockchain has been almost discontinued, which gives a yet another indication of a low chance of introducing a competing to Ethereum cryptocurrency as a result of the hard fork.
There is still a significant number of old nodes to be upgraded but if anyone is mining the old Ethereum, is probably doing it at a high price. The latest details of the upgrade have only been given to the developers shortly before the fork was activated, which resulted in developers and node operators working around the clock to get the updates out on time. Nonetheless, the update is one of the first significant upgrades to the network since the price and interest around Ethereum skyrocketed this year.
Even though it is still early to doom the success rate of the fork that has been executed only a few hours ago, developers agreed on the upgrade running smoothly so far. The software is now stable and is steadily introduced across the distributed network. The network, however, needs an adjustment period as some of the blocks are currently mined as quickly as 1 second, while others can take up to a minute — considerably longer than an average of 25 seconds per block, according to the Ethereum fork tracker.
The good news, though, is a high number of transactions going through the blocks, but without slowing down the network.

The delay follows a suggestion made by ethereum founder Vitalik Buterin, who recommended in a core developer discussion today that the platform should be conservative relative to previous forks. The suggestion was made, in part, in order to nudge miners into adopting the hard fork more successfully. This is because the difficulty increase intended to incentivize miners to swap onto a different chain has not become too high, and blocks would still be mineable throughout October.
Buterin wanted to push the release right to the end of the month, but was discouraged due to the scheduling clash with the ethereum developer conference in early November. The date for the hard fork is now "pretty much final" according to developer Hudson Jameson — unless of course, something goes wrong in the test period.
The testing phase for Byzantium on the Ropsten testnet officially kicked off on Tuesday , and to date everything is running as expected. The blockchain even verified its first private transaction following the fork. It was implemented to enable faster transactions and greater security on its blockchain while making smart contracts suitable for business transactions.
Key Takeaways A blockchain hard fork is a change that introduces incompatibility between the new and old blockchain. The Byzantium Fork was an update to Ethereum's blockchain and network that implemented changes for the existing and upcoming frameworks. There were nine changes in the Byzantium Fork. Understanding the Byzantium Hard Fork A hard fork of a cryptocurrency blockchain splits the blockchain in two, creating an old and new version.
The new and old versions are incompatible, and all new transactions are recorded on the new chain. The changes implemented in the Byzantium hard fork were designed to make Ethereum lighter, faster, and more secure.
Additionally, they continued to build the framework for the eventual switch to the proof-of-stake consensus mechanism. Goals of the Byzantium Fork When implemented by a community and a blockchain's developers, a hard fork generally has specific goals or improvements that make the fork necessary.
Smart Contract Stops Before the update, smart contracts could throw an error, and the initiator would still be charged the gas fees for the entire transaction. Gas fees for smart contracts can be costly, so this update kept contract creators from losing gwei—the small ether denomination used to pay for transactions—for a contract that didn't fully execute.
Embedding Transaction Status Code In Receipts Previously, transactions referenced a root parameter within the Merkle tree—the blocks that build on each other and secure the chain. The Merkle tree is a data structure that uses data within preceding blocks to create verification information that allows one block to be checked rather than checking every block every time there is a transaction.
Enhancing Cryptography The Byzantium upgrade included coding native to Ethereum's blockchain designed to lessen power requirements for the implementation of zk-Snarks. This is a zero-knowledge cryptography—where each party in a transaction can verify the other, but the information cannot be seen—that is increasingly becoming the privacy standard for cryptocurrency transactions.
The update introduced mathematically intensive computations that enabled systems to prove that they held the requisite cryptographic keys without divulging the contents of those keys. State Changes Transactions change the state of the blockchain, and smart contracts execute transactions.
Ommer Blocks When miners open new blocks on a blockchain, it's possible for more than one block to be mined at the same time due to the distributed nature of the blockchain. When this happens, the network chooses which block to add to the chain. In previous versions of Ethereum, the blocks that were not chosen were called ommer blocks—ommer is the gender non-specific term for a child's parent's sibling.
To understand this concept, imagine that blocks 24 and 24a were mined at the same time—consider them to be siblings. Block 24 was added to the blockchain. Block 25 is block 24's child, which makes block 24a the ommer block of block 25 parent block's sibling block. Previously, ommer blocks were not accounted for when the difficulty was adjusted. This update included ommer blocks in the block count to ensure the difficulty could not be manipulated by adjusting the ommer rate previously called the uncle rate.
Under Ethereum's proof-of-stake consensus mechanism, implemented in September , ommer blocks no longer are an issue because only one block is proposed at a time.

A hard fork is a change to the underlying Ethereum protocol, creating new rules to improve the system.
The protocol changes are activated at a specific block number. All Ethereum clients need to upgrade, otherwise they will be stuck on an incompatible chain following the old rules. What happens if I do not participate in the hard fork?
If you are using an Ethereum client that is not updated for the upcoming hard fork, your client will sync to the pre-fork blockchain once the fork occurs. You will be stuck on an incompatible chain following the old rules, without replay protection against the main network. Old clients will be able to construct transactions, but will not be able to see the effects of those transactions.
