Updated April 16th at 10:50am UTC: This article has been updated to clarify the relationship between Astaru and Soniaum.
Japan’s Web3 adoption collective bridging Aster network and Soneum Astral said it has reduced Soneum’s blockchain final time by more than 98% as it aims to solve one of the biggest challenges in blockchain scalability.
Astar announced its strategic partnership with Altlayer and Eigenlayer, launching the “fast final layer” of Soneium, a Layer 2 (L2) blockchain network developed by Sony Block Solutions Labs.
In blockchain payments, finality is a guarantee that a transaction is irreversible and occurs after it is added to a block in a block in a block in a blockchain ledger.
The new final layer provides cryptoeconomic security assurance through a distributed router network, reducing reliance on centralized sequencers, allowing for more secure cross-chain interactions.

This could result in the finality of the transaction after 10 seconds of Soneium, according to an announcement shared with CointeLegraph.
The new validator network is protected by both RESTAKED ETHER (ETH) and Astar (AST) tokens.
According to Maarten Henskens, Head of Astar Foundation, the decline in blockchain finality is key to enabling more advanced distributed financial (DEFI) use cases and improving developer and user experience, as most solutions experience the final delay in 15 minutes to several days.
The new partnership is “an important step towards safe, fast, cross-chain interoperability,” he told Cointelegraph, adding:
“This is a fundamental improvement in UX and trust. If transactions are reversed, users don’t have to wait, no need to “double check” and developers can confidently build interactive applications in real time without worrying about delays. ”
“This milestone is just the beginning, and there’s a much bigger story unfolding about how quickly finality changes the developer’s UX, Defi and Crosschain experiences,” he added.

Arbitrum One is currently the fastest blockchain, with an average final time of 1 minute, just like Coinbase’s base L2 network, both relying on optimistic rollups, L2Beat data shows.

Important bottlenecks for adoption of blockchain L2 finality
According to Altlayer CEO YQ Jia, the solution to blockchain finality remains the biggest barrier to mainstream Web3 adoption.
“By combining the rebuilding of Eigenlayer with the verification and support of Astar Network’s Mach, we create an infrastructure that offers the best world of both. “This is exactly the kind of solution needed to bring blockchain technology to mainstream adoption.”

Eigenlayer has been trying to move forward with adoption of mainstream blockchain since its inception.
In February 2025, Eigenlayer and Blockchain Protocol Cartesi launched a new initiative to find the next important prototype consumer application with new use cases that could enhance mainstream crypto adoption.
