Astar is a layer-2 blockchain from
Japan. Astar provides Web3 infrastructure for Japanese organizations and
Japanese companies.
Organizations and companies that use
Astar network such as Sony Network Communication Inc. and the Nippon Telegraph
and Telephone Corporation (NTT).
Astar is a zkEVM layer-2 chain, it was
built using Polygon Chain Development Kit (CDK). Astar zkEVM officially went live on Mar 6, 2024.
Polygon CDK is a modular (it supports
Celetia’s DA and other data availability providers to reduce transaction fees),
open source software toolkit for developers to launch their own zkEVM chains.
Astar zkEVM is the first Polygon CDK
chain to plug in to the AggLayer.
AggLayer allows Astar zkEVM to make
cross-chain transactions between Astar and Polygon zkEVM as well as between
Astar and other Polygon CDK chains.
Projects built on Polygon CDK.
What is AggLayer?
Polygon Labs researchers and software engineers have designed an
interoperability protocol for zero-knowledge blockchains called AggLayer.
AggLayer will unify ZK-secured L1 and L2 chains and makes it
feel like a single chain.
How does AggLayer works?
It aggregates ZK proofs from all connected chains to create
cross-chain transactions.
Polygon CDK chains, L2 chains, L1 chains that use zero-knowledge
proofs can use AggLayer.
Polygon Labs launched AggLayer mainnet on Feb 23, 2024.
