Understanding Blockchain Forks
A blockchain fork is a radical change to the underlying protocol of a blockchain network.
Soft forks are backward compatible upgrades to the blockchain protocol. This means that the new protocol can still work with the old protocol, and the nodes that haven’t upgraded their software can still participate in the network. Soft forks usually involve changes that are backward compatible and don’t require every node to upgrade to the latest version of the software.
Hard forks, on the other hand, are radical changes to the protocol, which are not backward compatible. This means that the nodes that haven’t upgraded their software will not be able to participate in the network. Hard forks usually involve changes that are not backward compatible, and every node needs to upgrade to the latest version of the software.
A good example of a soft fork is the introduction of Segregated Witness (SegWit) in Bitcoin. The primary purpose of SegWit was to reduce the size of transactions, thereby improving the scalability of the Bitcoin network. This protocol upgrade was backward compatible, and nodes that didn’t upgrade their software could still participate in the network.
A good example of a hard fork is the Ethereum Classic hard fork. In 2016, the DAO (Decentralized Autonomous Organization) on the Ethereum network was hacked, and the attackers stole around $50 million worth of Ether. To recover the stolen funds, the Ethereum community decided to hard fork the network, which meant that the old blockchain was abandoned, and a new blockchain was created. The new blockchain was incompatible with the old blockchain, and the nodes that didn’t upgrade their software could no longer participate in the network.
