Comparison of Layer 1 blockchains by finalization time
April 2026The comparison was conducted in April 2026.
For comparison, Layer 1 blockchains from the TOP-30 on CoinMarketCap were selected.
Layer 2 solutions and specialized chains designed exclusively for trading (such as Hyperliquid) were not included in the comparison.
TON
Block finalization time—that is, the time from when a block containing a transaction is confirmed until the transaction, along with the transaction and block hashes, becomes guaranteed to be immutable—is ~0.6 seconds.
This time includes the wait time until the next masterchain block (~block time / 2) and the confirmation of the masterchain block (~block time). The block time on the TON mainnet is ~0.4 seconds.
The total time, including the time it takes for the first shardchain block to be confirmed, is just under 1 second.

Avalanche C-Chain / Primary Network
"Avalanche consensus provides fast and irreversible finality with ~1 second" https://build.avax.network/docs/primary-network/exchange-integration#determining-finality
https://build.avax.network/docs/primary-network/avalanche-consensus
BNB Smart Chain
"this means finality is achieved in approximately **1.125 seconds" https://docs.bnbchain.org/bnb-smart-chain/introduction/#fast-finality
SUI
" If a transaction includes shared objects, it happens shortly after consensus, which can take a few seconds. "
https://docs.sui.io/develop/transactions/transaction-lifecycle#settlement-finality-timing
Hedera
"Users are thus guaranteed deterministic finality (as opposed to probabilistic finality) of smart contract executions within 2-3 seconds while ensuring that state changes are entirely encompassed within smart contract functionality." https://docs.hedera.com/hedera/core-concepts/smart-contracts/security#evm-equivalence

Monero
Technical specs give 2-minute blocks. "Newly received transactions require 10 confirmations on the blockchain before being unlocked."

Bitcoin
Bitcoin Developer Guide: 6 confirmations ≈1 hour and arbitrary/practical nature of the threshold.

Cardano
"Transaction finality can be achieved in approximately one day, and cannot happen in less than a day, according to Ouroboros consensus design."
