Polygon's AggLayer has gained significant attention following the announcement of Pessimistic Proof. Polygon values this topic so much that it has created several related tasks on the #PolygonHub #MATIC✅
The #SocialMining members at @DAO Labs have started to investigate and announce the topic thoroughly.
So, what is Pessimistic Proof?
Pessimistic Proof is a security mechanism offered by #Polygon AggLayer that provides cryptographic security in cross-chain transactions. Here are the details on how it works:
1. Unified Bridge:
- AggLayer aims to scale liquidity, users, and states by combining rollup chains in the Ethereum ecosystem.
- The unified bridge connects chains like OKX's X Layer, Astar zkEVM, and Polygon zkEVM to #Ethereum This ensures seamless asset transfers between L2 chains.
2. Security Issue:
- The security risk increases as AggLayer expands by incorporating different chains into the unified bridge.
- A security vulnerability in any chain could impact the entire bridge.
3. Pessimistic Proof:
- Pessimistic Proof treats all chains as insecure and incompatible with each other.
- It constantly audits whether the chains provide accurate information about the deposited assets.
- This way, a security issue in one chain does not affect the others.
4. Conclusion:
- Pessimistic Proof ensures cross-chain security and prevents one chain from risking the funds of others.
- AggLayer maintains the security guarantees of each chain while ensuring the security of all chains on the unified bridge. 🛡️🌐
