Finality
Last updated:
Applies to: All chains
In more detail
Each chain signals finality differently. Ethereum exposes block tags: latest (the head, which can still be reorganised), safe and finalized. Solana exposes commitment levels, with finalized meaning maximum lockout. TRON calls a block solidified once at least 19 of its 27 super representatives have built on it.
Before finality a transaction is included but can still be dropped by a reorganisation, so deposits and other irreversible actions usually wait for the chain's finalized signal, while user interfaces may show earlier, tentative states.
