@BitlayerLabs's core innovation lies in injecting the security genes of Bitcoin into Layer2 (see Chapter 4 of the white paper for details).

1. Data Availability Layer: Utilizes Bitcoin to store critical state compressed copies, resisting data withholding attacks through asymmetric backups.

2. State Proof Layer: Anchors zk-STARK proofs to Bitcoin scripts (OP_RETURN+Taproot), achieving Bitcoin-level censorship resistance.

3. Driving Verification Layer: Uses BTC block hashes to drive the fraud proof challenge window (dynamically adjusted between 10-24 hours), breaking the "liquidity-security" paradox.

💡 Key Differences with Competitors

• Compared to OP Stack: No 7-day challenge period (Bitlayer averages 15 hours finality).

• Compared to zkSync: Proof generation costs reduced by 87% (optimizing proof aggregation using Bitcoin block intervals).

📈 Ecosystem Explosion Critical Point

Current TVL has surpassed $3.2B, and the Runes protocol's gas efficiency on Bitlayer is 23 times better than the mainnet (see Dune Analytics dashboard for details). The next phase is predicted to see: #Bitlaye

✅ Native Bitcoin DEX's L2 liquidity aggregation (such as @BisoProtocol).

✅ Real yield market for BTC staking derivatives.

#Bitlayer is redefining the security boundaries of Layer2 with Bitcoin, and developers are advised to pay close attention to updates of its DA layer's open-source toolchain (Devnet v2 expected to be released on August 18).
