主要洞察：
- Cardano 相关报道称，该网络将推出 Dijkstra 硬分叉 分两个阶段进行，Linear Leios 预计于 2026 年推出。
- Peras 激活计划在 Dijkstra 第一阶段落地后于 2027 年第二季度进行。
- Amaru targets Cardano mainnet block production in November 2026.
Cardano developments took a fresh direction following Intersect’s publication of the roadmap for the Dijkstra 硬分叉. The schedule outlines a two-phase rollout for structural upgrades and new network features.
根据报告，第一阶段的目标是 2026 年第四季度，将引入 Linear Leios 以及多项账本和交易增强功能。第二阶段计划于 2027 年第二季度通过激活 Ouroboros Peras 启动。
Cardano 新闻：Cardano 升级进入第一阶段
As detailed in recent Cardano updates, the network upgrade commences with Protocol Version 12 during the Dijkstra era. This initial step triggers a 硬分叉 to activate Ouroboros Linear Leios, which is designed to boost volume a network can handle without fees or delays exploding.">throughput while retaining the core security guarantees of the Praos protocol.
To accommodate extra transaction references, the architecture relies on Endorser Blocks and Ranking Blocks. While Ranking Blocks build upon traditional Praos blocks with added announcement fields, Endorser Blocks contain transaction references instead of the transactions themselves.
Once an Endorser Block receives certification, a subsequent Ranking Block applies those transactions directly to the ledger. This certification demands aggregated signatures that fulfill a 75% quorum from active stakeholders, allowing Cardano to handle higher transaction volume without needing faster slots or larger block sizes.
第一阶段还通过 CIP-118 引入了嵌套交易（Nested Transactions），并通过 CIP-112 引入了 Guard Scripts。此外，账户地址增强第一阶段（Account Address Enhancement Phase 1）建立了账户式地址的账本级定义，同时升级取消了交易 isValid 字段并推出了 PlutusV4 脚本上下文。
Cardano 新闻概述主网前测试
The roadmap details a structured testing phase prior to any mainnet deployment. A Dijkstra-compatible node will initially be released to testnet operators, followed by a roughly two-week Preview 硬分叉 testing window.
This testing period focuses on tool validation, integration checks, volume a network can handle without fees or delays exploding.">throughput benchmarking, and Endorser Block propagation. Pre-production testing will then run for one to two weeks before advancing to a mainnet governance action.
Deploying to the mainnet requires governance ratification alongside a Hard Fork Initiation action, though the schedule does not specify an exact launch date. Additionally, phase one must put the foundational structural requirements in place to support the subsequent Peras activation.
由于 Peras 计划作为 2027 年第二季度的时代内硬分叉，因此必须在 Dijkstra 的第一阶段集成必要的协议参数和区块结构。这项基础工作确保第二阶段可以直接激活 Peras，而无需启动全新的账本时代。
ADA 价格和 Dijkstra 额外准备工作
来自 CoinMarketCap 的数据显示，该 ADA 价格 交易价格为 $0.176753，24 小时交易量为 $114,136,558，市值为 $6,461,346,460。
同时，Intersect 注意到 Amaru（一个基于 Rust 的 Cardano 节点实现）的稳步进展。该软件目前能够与网络尖端同步、中继和验证数据，开发人员的目标是到 2026 年 11 月实现主网区块生产。
Dijkstra 的筹备工作还包括对 Cardano 宪法进行技术更新，以便在激活后规范网络的新功能。其他更改包括取消奖励提取的 DRep 规范的 CIP-181，以及实施质押奖励杠杆参数的 CIP-50。
默认情况下，CIP-50参数保留了现有的奖励机制。第一阶段还将通过引入CIP-23为公平最低费用（Fair Min Fees）奠定基础。
