In milliseconds,irreversible,every time
Finality on Avalanche is irreversible: no reorgs, no settlement window. The shared C-Chain settles in under a second; a dedicated L1 can push it below 100 milliseconds. Both run the EVM by default, so Solidity contracts and existing tooling carry over unchanged.

06How it works.The primitives underneath.
01
High-performance EVM
The C-Chain and every L1 run the EVM by default: Solidity, Foundry, and the wallets your users already have work unchanged.
02
Irreversible settlement
Snowman consensus accepts each block exactly once. No confirmation counting, no reorg window, no clawback of settled value.
03
Dedicated blockspace
Each L1 has its own validators, gas token, and fee market. Someone else's busy application never touches your latency.
04
Horizontal scale
Capacity grows by adding L1s: each new chain brings its own validators and fee market instead of bidding for shared blockspace.
Where it is used.Institutional patterns built on it.
Cross-border payments
Across borders in under a second.
Correspondent banking moves money across borders through a chain of intermediaries, each adding hours or days, cutoff windows, and fees. The value arrives when the last bank in the chain says it does, and not before.
Stablecoin transfers on the C-Chain settle irreversibly in under a second, any hour of any day.

DVP settlement
Delivery versus payment, atomically.
Two parties exchange an asset for payment and both need certainty that delivery and payment settle together or not at all. Off-chain that certainty costs settlement risk and reconciliation; on most chains it costs a reorg window. Irreversible finality closes both.
Securities and cash change hands in a single settlement, each leg visible only to its counterparties.
