Blockchain Finality Tracker
See how long each blockchain takes to reach safe settlement finality. Select a risk level to adjust the recommended number of confirmations — from a quick low-value transfer to a high-value institutional settlement.

Probabilistic
Bitcoin
No hard final point. Each confirmation exponentially reduces reversal probability. After 6 Bitcoin blocks, reversal is economically irrational.
Economic
Ethereum PoS
Finality is enforced by slashing. To revert a finalised checkpoint, the attacker must destroy >1/3 of staked ETH — billions of dollars.
Deterministic
Solana, Avalanche
BFT-style consensus where a supermajority of validators must agree. Once committed, the block is final — no probabilistic element.
