The recent deployment of AggLayer v0.2 on the mainnet promises to bolster the overall security architecture of AggLayer.
In Brief
As part of its v0.2 rollout, AggLayer has revealed the implementation of pessimistic proofs on its mainnet, a considerable advancement that sets the stage for the protocol to enable secure multistack integration.

Decentralized protocol AggLayer The introduction of pessimistic proofs in the AggLayer v0.2 upgrade marks another milestone towards allowing the protocol to securely facilitate multistack capabilities.
This upgrade brings enhanced compatibility for a diverse range of blockchains, allowing various security frameworks to interconnect via AggLayer. In the past, only those chains developed using Polygon CDK could securely link to the network. Now, chains that do not utilize zero-knowledge (ZK) execution proofs are also on the verge of connecting to the mainnet with this new upgrade. zero-knowledge The AggLayer v0.2 launch incorporates two vital elements: the capacity to link chains with differing security paradigms and improved safety for cross-chain operations.
Pessimistic proofs are essential for guaranteeing that no chain can withdraw more assets than it has deposited into the unified bridge. This approach, which treats all chains with a level of skepticism regardless of their security framework, enhances the overall safety for all interconnected chains.
These pessimistic proofs serve as the cornerstone for cross-chain security, enabling AggLayer to truly achieve a stack-agnostic architecture.
Thanks to the pessimistic proof mechanism, AggLayer maintains a streamlined yet versatile design.
The introduction of the pessimistic proof allows multiple chains to consolidate safely via AggLayer. This proof is generated by collecting three crucial elements: ensuring chains process updates appropriately, verifying chains maintain accurate internal accounting, preventing any chain from withdrawing tokens that it has not deposited, and confirming that each chain adheres to correct internal accounting practices. This comprehensive approach allows AggLayer to vigilantly supervise every chain, ensuring that no chain can pull out more from the bridge than it has input. Consequently, chains that fail to comply with protocols present risks solely to themselves rather than the wider aggregated network. This model is vital for AggLayer's ambition to become truly stack-agnostic.
AggLayer has shared its vision of evolving into a fully multistack network.
The integrated blockchain architecture combines the advantages of both monolithic and modular scaling methods, ultimately aiming to provide a cohesive framework for secure and atomic interoperability among various blockchains.
This decentralized protocol operates through two primary elements: a communal bridge and a ZK-enhanced system that guarantees cryptographic integrity for seamless cross-chain interoperability. With the security afforded by ZK proofs, chains connected to AggLayer will preserve their autonomy and modular characteristics while enjoying the improved user experience synonymous with monolithic chains.
AggLayer In a move towards transparency and community-driven development, AggLayer has announced that the v0.3 update, set for release at the end of the first quarter, will introduce comprehensive multistack capabilities. This enhancement will facilitate the connection of EVM-compatible chains with AggLayer.
