Just recently, a software developer and “Solidity nerd” called Bunny Girl has sparked heated conversations within the cryptocurrency community over a smart contract that reveals a process called a “Request For Reorg contract (RFR).” On Twitter, Bunny Girl explained that the contract “creates a mechanism that allows users to pay miners to reorg the Ethereum blockchain.” Ever since then, the tweet went viral and there have been lots of debates over whether or not blockchains, in general, are immutable.
Solidity Developer Reveals Blockchain Reorganization Smart Contract for Ethereum
Conversations and debates concerning blockchain immutability have been taking place for years, and a fresh new discussion has ignited over a tweet and smart contract published on Github by the developer Bunny Girl. On July 10, Bunny Girl explained that the smart contract aims to enhance systematic chain reorganizations.
A blockchain reorganization is a contentious subject and basically occurs when a chain of recorded blocks is invalidated. Reorganizations have taken place on various blockchains when a mining entity or group of miners controls more than 51% of the hashrate.
Blockchain reorganizations force miners (not participating in the reorg) back to a point where they have to start again from a specific block height. It’s akin to rolling back a recorded history of transactions and then re-recording them again, but of course, the new transactions would never be the same as the ones that were erased.
