Learn about our editorial policies What Was the Byzantium Fork? The Byzantium hard fork was an update to Ethereum's blockchain, implemented in October at block 4,, 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. When miners complete a block, they are rewarded with cryptocurrency.
The hype around the Ethereum merge, which finalized the network's move to proof of stake, pushed the price of Ethereum-related coins higher, including the native cryptocurrency of OG blockchain Ethereum Classic. But the crypto bear market has been brutal, and most of these gains have already been wiped off the table.
EthereumPoW's first month of life has been bumpy, and if it's any indication of the future, former Ethereum miners may need to look elsewhere for profits. ETHW began trading on exchanges as an IOU token prior its network launching, and it enjoyed some early, though ultimately short-lived, enthusiasm. Besides the price of its native crypto tanking, EthereumPoW also suffered technical issues that caused problems with its launch.
Shortly after the network went live on September 15, blockchain detectives discovered that the ETHPoW developers had chosen a chain ID that was already in use.
