In a major milestone for Ethereum and Layer 2, Optimism, the Layer 2 scaling platform for the second most valuable network, announced the activation of its open source software and permissionless fault protection.
Even though the platform manages over $7 billion in assets, according to L2Beat,Optimism, like most confident summaries, had no way to ,reliably verify transactions. This feature relied on a centralized sequencer and a cheat-proof system.
Optimism activates a trustless fraud-resistant system
Activating the open source fault-tolerant system is critical to creating a more decentralized and secure future for the Optimism ecosystem. Overall, error proofing is a key element in allowing users to verify the validity of all off-chain transactions.
Most importantly, it allows users to challenge any fraudulent activity on the Optimism platform, creating protection against unauthorized withdrawals and more.
In the post, Optimism Laboratories he said the layer 2 platform was based on a centralized system. In this case, the Optimism Security Council had the authority to initiate withdrawals.
However, the platform eliminates this dependency by implementing reliable failure protection. This means that any user can withdraw tokens without council intervention. The power shift is huge for community and decentralization.
Nevertheless, to ensure the sheltered implementation of this fault-tolerant system, the Optimism Safety Board will still have the authority, at least temporarily, to intervene in the event of critical failures. This decision means that Optimism will continue to operate securely as it gradually decentralizes.
Ultimately, the platform plans to release a “multi-proof nirvana,” open-source and modular, likely including zero-knowledge proofs. This goes beyond the current “Armata” system.
Buterin’s confirmation, but why does OP crash?
Vitalik Buterin, co-founder of Ethereum, found this milestone, welcoming Optimism to the “Stage 1+ L2 Club”. Nevertheless, the co-founder still needed more zero-knowledge Layer 2 platforms to join his ranks.

Optimism is the second Layer 2 platform after Arbitrum to announce fault-tolerant systems, although both are still being tested. Arbitrum’s fraud-proof system, called “bounded liquidity delay” (BOLD). fired on Testnet early last month.
Despite this milestone, the OP remains unwavering, but is under pressure in the first half of June.
At spot rates, OP is down about 55% from March highs. With Ethereum and Bitcoin prices under pressure, the token could break the May lows of $1.8 with an eye on $1.1.
