你有多久没关注 Rollup 相关的话题了? 对于未来是否会迎来新一轮发展,我无法给出明确判断,但区块链技术本身一直在稳步推进。 由 Rollup 衍生的Layer2一键发链技术,正试图解决多链生态下用户注意力分散的问题。 以 OP 为例,其 Superchain 已通过 ERC-7683 和 ERC-7802 升级了跨链意图机制和跨链代币接口,进一步优化了互操作性。 除了 OP 之外,Caldera 也在这一领域持续深耕。 Caldera 是一个模块化的 Layer2 发链技术堆栈,具备高度灵活性,并已实现生态内的跨链交互功能。 其核心组件 Metalayer 是一个跨链互操作性框架,其中包含两个关键部分:一是意图引擎,用于简化复杂的跨链操作流程;二是消息传递协议,支持多个 Caldera 链之间跨网络的实时数据传输。 这两者的结合使 Metalayer 成为一个无缝、安全且高效的跨链平台。 在 Rollup 的技术堆栈方面,Optimistic Rollups 可选用 Optimism Bedrock 和 Arbitrum Nitro,而 Zero-Knowledge Rollups 则有 Polygon CDK 和 ZK Stack 可供选择。 开发者在 Caldera 上可以通过模块化组件自由组合这四种技术堆栈。 在发链功能上,Caldera 支持自定义 Gas 代币,并可选择 Celestia 或 Near 作为数据可用性层(Data Availability)的解决方案。此外,它还支持去中心化排序器,避免了集中式排序器可能出现的单点故障和 MEV(矿工可提取价值)问题。
