Arbitrum Introduces New Protocol Aimed at Boosting Network Security

Catherine

2024/04/17 01:30

Offchain Labs has made waves with the rollout of Arbitrum BOLD on a public testnet, a noteworthy advancement in the Arbitrum ecosystem.

We’re thrilled to see Arbitrum BOLD live in testnet!

Since Arbitrum’s inception, Offchain Labs’ focus has been aligning with Ethereum’s vision of decentralized rollups.

The BOLD public testnet is the next step in its journey to becoming a Stage 2 rollup. https://t.co/668KkZ2ok4

Arbitrum Bolsters Security Measures

This innovative protocol is geared towards augmenting security by integrating interactive fraud proofs within optimistic rollups.

Additionally, it champions a transition towards completely permissionless validation across Arbitrum chains.

We’re excited to see the AIP for BOLD upgrade live in the ArbitrumDAO forum for community feedback.

This proposal would allow permissionless validation on all Arbitrum chains - a monumental step towards Arbitrum becoming a Stage 2 decentralized L2 rollup. https://t.co/DcuaMtDZ8w

Yesterday BOLD testnet went live, today the AIP for BOLD is live in the ArbitrumDAO forum!

For Arbitrum chains, BOLD proposes unlocking:

✅ Greater decentralization via permissionless validation
⚔️ Enhanced security
🤝 Pooled challenge fundinghttps://t.co/ZMaWjiRCc5

One of the standout features of Arbitrum BOLD is its introduction of a dispute resolution mechanism, empowering a single, adept entity to handle multiple challenges with precision, thereby reducing the necessity for numerous individual disputes.

BOLD is an extension Arbitrum’s current fraud proof mechanism via a fixed upper bound for disputes & a new, all-vs-all dispute design.
BOLD ensures that a single honest party can defend Arbitrum’s state and win disputes against malicious actors.

For those who want to deploy…

This approach not only streamlines the validation process but also bolsters the network's resilience against potential attacks.

The integration of BOLD into the Ethereum Sepolia testnet signals a strategic effort to engage the community in validating and refining the protocol.

Offchain Labs underscores the pivotal role of community feedback during this phase, ensuring the robustness and readiness of the system for broader adoption.

With permissionless validation as a cornerstone of the BOLD protocol, any user can now become a validator, marking a significant stride towards decentralisation by eliminating the need for a pre-approved list of validators.

With BOLD, Arbitrum chains can now handle delay attacks, which enables permissionless validation. A key milestone for Arbitrum chains towards being recognized as Stage 2 rollups!

This inclusive approach not only enhances network security but also fosters a more diverse and participatory validator community.

Offchain Labs wrote:

“It empowers anyone to secure claims made about Arbitrum's state on Ethereum. That is, withdrawals from Arbitrum back to Ethereum can be verified or challenged by anyone in the world, ensuring the correct history always remains correct.”

Anticipation mounts for the formal proposal to activate BOLD on Arbitrum Sepolia, followed by a community vote to seal the integration—a step in Arbitrum's journey towards a more decentralised and secure architecture.

What’s next?
The BOLD protocol will undergo rigorous testing and an audit before a DAO proposal will be made to activate this revolutionary upgrade to Arbitrum Sepolia in late Spring 2024 and then eventually Arbitrum One and Nova sometime in Summer 2024 if ArbitrumDAO approves.…

As part of this initiative, rigorous testing and audits, including assessments by Trail of Bits, are being conducted to uphold the protocol's integrity.
