Arbitrum拟将ZK证明集成至BoLD协议以缩短提现时间
Arbitrum ZK Settlement Plan Could Cut Withdrawals From Days To Hours
Offchain Labs is advancing work to integrate zero-knowledge proofs into Arbitrum’s BoLD settlement protocol, a move designed to reduce withdrawal times from seven days to a few hours while preserving optimistic fraud proofs.
Offchain Labs 正在推进将零知识证明集成到 Arbitrum 的 BoLD 结算协议中的工作，此举旨在将提款时间从七天缩短至几小时，同时保留乐观欺诈证明。
The system would use ZK fast confirmations alongside Arbitrum’s existing dispute architecture. That means the plan is not to remove fraud proofs entirely, but to add a faster proving layer that can improve user experience.
该系统将在 Arbitrum 现有的争议架构旁使用 ZK 快速确认。这意味着该计划并非完全移除欺诈证明，而是增加一个更快的证明层以改善用户体验。
The upgrade is not live on mainnet yet.
该升级尚未在主网上线。
A DAO vote is still required before deployment. So this is a roadmap and governance story, not a completed network change.
部署前仍需进行 DAO 投票。因此，这是一个路线图和治理故事，而非已完成的网络变更。
TL;DR
TL;DR（太长不看）
- Offchain Labs is working to integrate ZK proofs into Arbitrum’s BoLD protocol.
- The goal is to reduce withdrawal times from seven days to a few hours.
- Fraud proofs are not being removed, and mainnet deployment still requires DAO approval.
- Offchain Labs 正致力于将 ZK 证明集成到 Arbitrum 的 BoLD 协议中。
- 目标是将提款时间从七天缩短至几小时。
- 欺诈证明不会被移除，且主网部署仍需获得 DAO 批准。
Why Withdrawal Times Matter
为何提款时间至关重要
Optimistic rollups have a user-experience problem.
乐观层（Optimistic rollups）存在用户体验问题。
Their security model typically includes a challenge window, which can make withdrawals to Ethereum slow. Users may wait days unless they use liquidity providers or third-party bridging services.
其安全模型通常包含一个挑战窗口，这可能导致向以太坊的提款速度变慢。除非用户使用流动性提供商或第三方桥接服务，否则用户可能需要等待数天。
That delay is one of the biggest friction points for rollups.
这种延迟是滚动扩容方案（rollups）最大的摩擦点之一。
Reducing withdrawal times to a few hours would make Arbitrum feel faster and more competitive, especially for users moving assets between L2 and Ethereum mainnet.
将提款时间缩短至几小时将使 Arbitrum 感觉更快、更具竞争力，特别是对于在 L2 和以太坊主网之间转移资产的用户而言。
ZK proofs offer one path to that improvement.
ZK 证明为实现这一改进提供了一条路径。
Multi-Proving Gives Arbitrum More Flexibility
多证明机制赋予 Arbitrum 更多灵活性
The proposed model is important because it does not simply replace one proving system with another.
拟议的模型之所以重要，是因为它并非简单地将一种证明系统替换为另一种。
By combining ZK fast confirmations with optimistic fraud proofs, Arbitrum can potentially preserve parts of its existing security model while adding a faster settlement path.
通过结合 ZK 快速确认与乐观欺诈证明，Arbitrum 有可能在保留部分现有安全模型的同时，增加一条更快的结算路径。
That is the appeal of multi-proving.
这就是多证明机制的吸引力所在。
Different proof systems can support different trade-offs. ZK proofs can speed up verification, while optimistic mechanisms can remain part of the dispute framework.
不同的证明系统可以支持不同的权衡。ZK 证明可以加速验证，而乐观机制可以保留在争议框架内。
This hybrid approach may become more common as rollups mature.
随着滚动扩容方案的成熟，这种混合方法可能会变得更加普遍。
BoLD Is The Settlement Layer To Watch
BoLD 是值得关注的结算层
BoLD is Arbitrum’s dispute and settlement framework.
BoLD 是 Arbitrum 的争议和结算框架。
Integrating ZK proofs into BoLD would affect how the network confirms and settles state back to Ethereum. That makes the work important for Arbitrum’s long-term architecture, not just a surface-level user feature.
将 ZK 证明集成到 BoLD 中将影响网络如何向以太坊确认和结算状态。这使得这项工作对 Arbitrum 的长期架构至关重要，而不仅仅是一个表面层面的用户功能。
If the integration works, it could improve withdrawal speed without abandoning the system’s optimistic roots.
如果集成成功，它可以在不抛弃系统乐观根基的情况下提高提款速度。
That would be a significant technical step.
这将是一个重大的技术步骤。
But it needs governance approval and careful implementation.
但它需要治理批准和谨慎的实施。
Not Live Yet
尚未上线
The main caution is timing.
主要的注意事项是时机。
The upgrade should not be described as already active on Arbitrum mainnet. Development progress is not the same as deployment. A DAO vote is still needed, and implementation details may change before launch.
不应将此次升级描述为已在 Arbitrum 主网上激活。开发进度不等于部署完成。仍需进行 DAO 投票，且实施细节在发布前可能发生变化。
Crypto markets often price roadmap items early.
加密市场往往提前对路线图项目进行定价。
That can create confusion when users expect immediate changes. For now, withdrawals should not be assumed to have already moved from days to hours.
这会在用户期望立即看到变化时造成混淆。目前，不应假设提款时间已经从几天缩短到了几小时。
The plan is promising, but not finished.
该计划前景广阔，但尚未完成。
What Comes Next
接下来会发生什么
The DAO process is the next milestone.
DAO 流程是下一个里程碑。
If Arbitrum governance supports the deployment, attention will shift to rollout timing, security review, and real-world performance. Users will want to see whether withdrawals become reliably faster without adding new risks.
如果 Arbitrum 治理支持部署，关注点将转向推出时机、安全审查和实际表现。用户希望看到提款是否能在不增加新风险的情况下变得可靠地更快。
For Arbitrum, the upgrade could strengthen its position in the L2 market.
对于 Arbitrum 而言，此次升级可能会加强其在 L2 市场的地位。
Faster settlement would make the network more competitive against other rollups and alternative chains, while the multi-proving model could give developers more confidence in the long-term design.
更快的结算将使该网络在与其它 rollup 和替代链的竞争中更具竞争力，而多证明模型可能会让开发者对长期设计更有信心。
The broader message is clear: Arbitrum is not standing still. It is trying to make optimistic rollups feel faster without throwing away their security model.
更广泛的信息很明确：Arbitrum 并没有停滞不前。它正试图在不抛弃其安全模型的前提下，让乐观 rollup 感觉上更快。
