Dual Layer Transaction Finality Speed When You Want It, Security When You Need It
@BitlayerLabs has rolled out a dual finality framework that gives users and developers the freedom to choose lightning fast confirmations or Bitcoin level security depending on the transaction.
Soft Finality Instant Confidence in Seconds
When a transaction is included in a block validated by Bitlayer’s Proof of Stake (PoS) consensus, it reaches soft finality in under a second.
Perfect for payments, trades, and DeFi interactions where speed is everything.
Protected by the economic stake of validators, making it expensive for any bad actor to tamper with results.
🛡️ Hard Finality The Bitcoin Shield
For transactions that need maximum security, Bitlayer offers hard finality — achieved once the Layer 2 state with your transaction is fully settled on the Bitcoin mainnet.
Due to the optimistic rollup design and fraud-proof challenge period, this takes about 7 days.
Security only requires one honest participant to challenge fraudulent activity, giving it near-⁹Bitcoin-level safety.
⚠️ Safety First — Even in Rare Edge Cases
If an L1 challenge succeeds and creates a mismatch between L2 and L1 states, the system automatically pauses to protect assets.
Recovery and state alignment are then handled through social consensus among stakeholders, ensuring transparency and trust.
💡 Bottom Line:
Bitlayer’s dual-finality design delivers the best of both worlds — near-instant confirmations for everyday transactions, and uncompromising Bitcoin-backed protection for mission-critical settlements.
