Results for “Fork vs Soft fork”

Fork

A fork is a change to a blockchain's rules, or a split where two versions of the chain continue. A soft fork stays compatible with older software; a hard fork does not, and if some users reject it, two separate chains result, as with Ethereum and Ethereum Classic.

What it means for you. After a split, people who held coins at that moment usually hold them on both chains, but each exchange and wallet decides separately whether to support the new coin. A site asking for your seed phrase to 'claim' fork coins can take everything on both chains.

Soft fork

A soft fork is a change to a blockchain's rules that makes them stricter, so blocks following the new rules are still accepted by nodes that have not upgraded. In Bitcoin it can take effect without splitting the chain, provided miners with most of the hashing power enforce the new rules.

What it means for you. Your coins and older wallet software keep working after a soft fork, but an old node no longer checks every new rule and relies on the upgraded majority for those checks. Features a soft fork adds, such as new address types, work only once your wallet supports them.
