Mantle Network Migrates to Ethereum Blobs for Enhanced Security

Mantle Network is migrating to Ethereum blobs as its primary data availability layer, moving from a Validium setup to a full ZK rollup architecture secured by Ethereum. The timeline for completion is not specified.
Validiums store data off-chain, while ZK rollups post data directly on Ethereum, offering stronger security guarantees for transaction records.
The Fusaka upgrade on Ethereum in December 2025 increased blob throughput eightfold, enhancing Layer 2 data handling capacity.
Mantle holds $1.51 billion in total value secured, ranking 5th among Layer 2 networks behind Arbitrum, Base, Optimism, and Polygon.
Despite the migration, Mantle continues its partnership with EigenLayer for specialized use cases such as perpetuals and AI agent infrastructure.
The September 2025 upgrade to OP Succinct integrated ZK proofs for state validation, leading to record highs for MNT.
Ethereum blob data is retained for about 18 days, offering Ethereum-native security but limited long-term access compared to off-chain solutions.
