At a time when the world of cryptocurrencies is increasingly seeking decentralization and security, the Optimism network takes a significant step. In a recent publication, OP Labs – behind the development of Optimism – announced the launch of a testnet version of a fail-safe system. This advancement aims to transform Superchain into a more decentralized and efficient platform.
To date, networks using OP Stack technology, such as Optimism, have relied on centralized sequencers to group and forward transactions to Ethereum. This centralization presented a problem: not allowing users to send proof of fraud in case of incorrect data sent by the sequencer. This gap generated warnings, such as that from L2Beat, which highlighted the risks inherent to this dependence.
The search for decentralization is not new. Vitalik Buterin, co-founder of Ethereum, has previously argued that optimistic rollups, scalability layers that use Ethereum as collateral, should allow users the ability to submit proof of fraud. In other words, for these networks to be truly decentralized, they must offer mechanisms that prevent fraud and centralization.
OP Labs’ new proposal addresses precisely this concern. The failsafe system is composed of three components: a failsafe program, a failsafe virtual machine and a “dispute game protocol”. This modularity means that each network can adapt and implement its own fraud prevention system. This, in turn, promises to bring beneficial diversity to the Optimism Superchain.
More interestingly, the team behind Optimism suggests that individual networks could even incorporate zero-knowledge proofs (ZK proofs) as a prevention method. These are often used in zero-knowledge rollups.
Optimism, with its vision of an interconnected “Superchain,” is not alone in its mission. Other networks, such as Polygon’s ZK Supernets and the Ethereum Virtual Machine Hyperchain, are on the same path, showing the dynamism and continuous evolution of the crypto universe.
