Sony’s Soneium taps EigenLayer to cut finality to under 10 seconds

3 weeks ago

Soneium, a layer-2 (L2) blockchain web developed by Sony Block Solutions Labs, said it has slashed its blockchain finality clip by implicit 98%, arsenic it aims to lick 1 of the biggest challenges successful blockchain scalability.

Astar, a Japanese Web3 adoption corporate bridging Astar Network and Soneium, announced a strategical concern with AltLayer and EigenLayer to motorboat a “Fast Finality Layer” for Sony’s L2 blockchain.

In blockchain settlement, finality is the assurance that a transaction is irreversible, which happens aft it is added to a artifact connected the blockchain ledger.

The caller finality furniture provides a crypto-economic information warrant done a decentralized web of validators to trim the reliance connected centralized sequencers and alteration much unafraid crosschain interactions.

This could effect successful a sub-10-second transaction finality for Soneium, a 98% simplification from its archetypal 15-minute finality, which was achieved done Optimism’s OP Stack, according to an announcement shared with Cointelegraph.

The caller validator web volition beryllium secured by some restaked Ether (ETH) and Astar (ASTR) tokens.

Reducing blockchain finality is cardinal for enabling much precocious decentralized concern (DeFi) usage cases and improving developer and idiosyncratic experience, since astir solutions acquisition finality delays from 15 minutes to respective days, according to Maarten Henskens, caput of Astar Foundation.

The caller concern is simply a “crucial measurement toward secure, high-speed, crosschain interoperability,” helium told Cointelegraph, adding:

“It’s a foundational betterment successful UX and trust: users nary longer request to hold oregon “double-check” if a transaction volition beryllium reversed, and developers tin confidently physique real-time, interactive applications without worrying astir delayed finality.”

“This milestone is conscionable the opening — and there’s a overmuch larger communicative unfolding astir however accelerated finality volition reshape developer UX, DeFi, and crosschain experiences,” helium added.

Arbitrum One is presently the fastest blockchain, with an mean finality clip of 1 minute, the aforesaid arsenic Coinbase’s Base L2 network, some relying connected optimistic rollups, L2beat information shows.

Blockchain L2 finality a cardinal bottleneck for adoption

Solving blockchain finality remains the biggest obstruction to mainstream Web3 adoption, according to YQ Jia, CEO of AltLayer.

“By combining EigenLayer’s restaking with MACH validation and enactment from Astar Network, we’re creating an infrastructure that offers the champion of some worlds — Ethereum’s information guarantees with near-instant finality,” Jia said. “This is precisely the benignant of solution needed to bring blockchain exertion to mainstream adoption.”

EigenLayer has sought to beforehand mainstream blockchain adoption since it launched.

In February 2025, EigenLayer and blockchain protocol Cartesi launched a caller inaugural to find the adjacent cardinal prototype user exertion with caller usage cases that whitethorn bolster mainstream crypto adoption.
