**Sigma 6.0** 是对Ergo区块链的重大升级提案。它为开发者提供了更强大的工具来构建智能合约，修复了长期存在的限制，并为网络未来的改进做好准备——所有这些都不会破坏与现有合约或节点的兼容性。

该升级通过软分叉进行，这意味着现有的非挖矿节点可以继续运行，而升级后的挖矿节点则需要激活并执行新功能。

矿工的投票已经开始，目前支持率超过90%，并且开发网络已上线进行早期测试。如果这种趋势持续下去，Sigma 6.0 将在2025年9月底激活。


---

## 为什么需要Sigma 6.0？

自2019年Ergo推出以来，其智能合约语言（ErgoTree）保持稳定。这种稳定性帮助网络保持安全，但也使得开发者更难添加新功能或简化逻辑。一些改进早在2018年的测试网阶段就已计划，但从未进入主网——直到现在。

Sigma 6.0 将这些升级带到前面。它扩展了合约中的可能性，消除了技术限制，并为未来的治理和扩展改进铺平了道路。

---

## 有什么变化？

* **更强大的数字**，引入新的无符号256位整数类型，用于加密和金融操作
* **更好的数据处理**，通过对合约中复杂类型的序列化和反序列化的全面支持
* **更智能的交易**，可以访问来自其他输入的上下文变量，以实现更协调的逻辑
* **新的数学和列表工具**，包括按位操作、位移和增强的集合方法，如 `.get` 和 `.startsWith`
* **内置的PoW验证**，使合约能够检查区块头或自定义消息与Autolykos2的匹配
* **可升级的治理**，允许网络通过未来的软分叉投票新参数，从支持子区块开始



---

## 激活时间表

Sigma 6.0 正在经历一个软分叉激活过程，需要两个阶段：投票期和更新期。每个阶段大约持续45天，使得完整的推出大约需要90天。

矿工们在2025年7月初开始投票，支持率已经超过所需的90%阈值。如果这种支持水平保持不变，升级将在2025年9月底激活。

即使共识提前达成，协议仍需等待完整的投票和更新期才能上线。

Sigma 6.0 的开发网络已经上线，开发者可以在社区开发聊天中找到如何加入的信息。在7月，支持子区块的挖矿节点的测试在测试网上开始。之后，重点将转向完善文档和提高整个8月的安全性正式推理，确保升级保持以研究为驱动。一旦完成，注意力可以转向潜在的主网部署。

---

## 对开发者的影响

新功能需要ErgoTree版本3或更高。一些类型——如 `Option`、`Header` 和 `UnsignedBigInt`——不能直接存储在寄存器或上下文扩展中，但可以作为字节数据存储并在合约内部恢复。

示例用法可以在[GitHub上的Sigma测试套件](https://github.com/ergoplatform/sigmastate-interpreter/blob/b754e143cf38ed86d95698ede744a470dfa053d6/sigmastate/src/test/scala/special/sigma/SigmaDslSpecification.scala#L10040)中找到。

---

## 为什么这很重要

Sigma 6.0 是自网络推出以来对Ergo智能合约层的最大升级。它为开发者提供了更多自由，解锁了全新的用例，并加强了协议的基础——同时保持完全向后兼容。

随着矿工支持率现在超过90%，升级有望在今年9月激活。Sigma 6.0 使Ergo在未来处于更强的位置。

**Sigma 6.0** is a major proposed upgrade to the Ergo blockchain. It gives developers more powerful tools to build smart contracts, fixes long-standing limitations, and prepares the network for future improvements—all without breaking compatibility with existing contracts or nodes.

The upgrade is happening through a soft-fork, meaning existing non-mining nodes can continue operating, while upgraded mining nodes are required to activate and enforce the new features.

Voting by miners is already underway, with support currently over 90%, and a devnet is live for early testing. If this continues, Sigma 6.0 will activate in late September 2025.


---

## Why Is Sigma 6.0 Needed?

Since Ergo launched in 2019, its smart contract language (ErgoTree) has stayed stable. That stability has helped the network stay secure, but it also made it harder for developers to add new features or simplify their logic. Some improvements were planned as far back as the testnet days in 2018 but never made it to mainnet—until now.

Sigma 6.0 brings those upgrades forward. It expands what’s possible in a contract, removes technical limitations, and clears a path for future governance and scaling improvements.

---

## What’s Changing?

* **More powerful numbers** with a new unsigned 256-bit integer type for cryptographic and financial operations
* **Better data handling** through full support for serializing and deserializing complex types in contracts
* **Smarter transactions** that can access context variables from other inputs for more coordinated logic
* **New math and list tools** including bitwise operations, shifting, and enhanced collection methods like `.get` and `.startsWith`
* **Built-in PoW validation** so contracts can check block headers or custom messages against Autolykos2
* **Upgradable governance** allowing the network to vote on new parameters through future soft-forks, starting with support for sub-blocks



---

## Activation Timeline

Sigma 6.0 is going through a soft-fork activation process that requires two phases: a voting period and an update period. Each lasts about 45 days, making the full rollout take roughly 90 days.

Miners began voting in early July 2025, and support is already over the required 90% threshold. If that level of support holds, the upgrade will activate in late September 2025.

Even if consensus is reached early, the protocol still waits for the full voting and update periods before going live.

A devnet is already live for Sigma 6.0, and developers can find information on how to join in the community dev chat. In July, testing of sub-block–supporting mining nodes began on testnet. After that, focus will shift to refining documentation and improving formal reasoning around security throughout August, ensuring that the upgrade remains research-driven. Once complete, attention can turn toward a potential mainnet deployment.

---

## For Developers

The new features require ErgoTree version 3 or higher. Some types—like `Option`, `Header`, and `UnsignedBigInt`—can’t be stored directly in registers or context extensions, but can be stored as byte data and restored inside the contract.

Example usage can be found in the [Sigma test suite on GitHub](https://github.com/ergoplatform/sigmastate-interpreter/blob/b754e143cf38ed86d95698ede744a470dfa053d6/sigmastate/src/test/scala/special/sigma/SigmaDslSpecification.scala#L10040).

---

## Why It Matters

Sigma 6.0 is the biggest upgrade to Ergo’s smart contract layer since the network launched. It gives developers more freedom, unlocks entirely new use cases, and strengthens the protocol’s foundations—while staying fully backward-compatible.

With miner support now above 90%, the upgrade is on track to activate this September. Sigma 6.0 puts Ergo in a stronger position for the future.

Sigma 6.0: A Smarter, More Flexible Ergo

Sigma 6.0：更智能、更灵活的Ergo

## 自主经济代理的实用愿景

Ergo区块链上的自主经济代理在真实的数字经济中执行有用的工作。它们通过创建内容和提供数据分析、模式识别等服务来产生收入。它们利用收入支付运营费用，如托管费和服务器成本，并使用现代工具，如SSH和加密友好的托管服务提供商。当有额外资金时，它们会重新投资以改善运营或创建具有优化参数的新代理。它们的工作重点是在支持独立决策和可预测结果的环境中创造经济价值。

## 公共区块链作为理想环境

公共区块链通过使用加密密钥保护代理的身份，因此代理在没有传统身份检查的情况下运作。智能合约通过执行所有参与者信任的预编写代码自动执行协议。区块链将所有经济互动带入一个统一的空间，代理可以在没有外部障碍的情况下进行交易、存储价值和管理金融工具。通过这种方式，区块链提供了一个支持透明、安全和信任的经济栖息地。

## 为什么Ergo是自主经济代理的理想栖息地

Ergo以其扩展UTXO模型脱颖而出，该模型在单独的盒子中存储状态。每个盒子都有自己的条件，因此代理仅将资金承诺给受信任的合约。该设计简化了点对点金融工具（如债券）的创建和跟踪。

由于状态在每个盒子中单独存储，影响不同盒子的交易可以同时发生而不会冲突。例如，一个代理可以在另一个代理同时执行交易时完成数据分析。当许多交易需要访问相同的信息时，系统使用数据输入允许对公共数据的只读访问，而不改变原始盒子。该设计保留了并行处理交易的能力，并增强了可扩展性。

该平台产生确定性的结果，这意味着代理可以在交易上线之前计算费用并预测交易结果。这种可靠的可预测性使代理能够自信地规划行动并有效管理风险。合约可以通过简单地修改盒子中的参数来更新，使代理能够根据市场条件的变化调整策略。隐私通过先进的加密方法内置于设计中，使代理能够在化名下运作。

## Ergo上的现实世界应用

在Ergo上，一个去中心化的数据分析代理监控流动性池数据和价格信息，生成有洞察力的报告，同时管理自己的费用和存储成本。
一个代理网络可以协作生成数字内容。一个管理代理分配任务，专业代理独立完成不同部分。系统的简单设计允许快速和可靠的协作。

在去中心化金融领域，代理可以作为流动性提供者或套利者。使用数据输入，代理根据当前市场信息不断优化其交易策略，并在条件变化时自动调整其方法。

代理还可以作为资源管理者，处理代币化资产，如计算能力或存储。它自动化租赁和定价决策，同时适应供需变化，从而保持资源的有效分配。

### Celaut：分布式代理执行框架

[Celaut](https://docs.ergoplatform.com/eco/celaut/)是一个正在开发的框架，将自主经济代理的概念带入实际焦点。它使代理不仅在逻辑上而且在部署上独立运作——打包为由去中心化节点执行的确定性服务。基于Ergo的智能合约和声誉原语，Celaut将服务创建者的角色与主机分开，使节点在用户根据公共表现和信任数据选择代理时赚取费用。该项目在链接的[ErgoForum线程](https://www.ergoforum.org/t/artifical-economic-intelligence-on-ergo-blockchain/4429)中积极讨论，开发者概述了Celaut如何帮助实现一个去中心化的、以声誉驱动的AI和经济代理生态系统。

#### 结论

Ergo的扩展UTXO系统为自主经济代理提供了一个强大且可预测的基础。其设计具有明确的合约边界、处理多个交易的能力以及随时间调整合约的灵活性。这些特性使代理能够在支持隐私和可靠规划的安全数字生态系统中执行有价值的经济工作。有关这些创新想法的更多细节，请参阅官方Ergo文档：[docs.ergoplatform.com/ai/](http://docs.ergoplatform.com/ai/)和kushti的原始ergoforum帖子[人工经济智能在(Ergo)区块链上](https://www.ergoforum.org/t/artifical-economic-intelligence-on-ergo-blockchain/4429)。

## A Practical Vision for Autonomous Economic Agents

Autonomous economic agents on the Ergo blockchain perform useful work in a real digital economy. They generate income by creating content and offering services such as data analysis and pattern recognition. They use their earnings to pay for operating expenses like hosting fees and server costs by using modern tools such as SSH and crypto friendly hosting providers. When extra funds are available, they reinvest in improving operations or create new agents with refined parameters. Their work focuses on generating economic value in an environment that supports independent decision making and predictable outcomes.

## Public Blockchains as the Ideal Environment

Public blockchains protect the identities of agents with the use of cryptographic keys, so agents operate without traditional identity checks. Smart contracts enforce agreements automatically by executing prewritten code that all participants trust. The blockchain brings all economic interactions into one unified space, where agents can transact, store value, and manage financial instruments without external obstacles. In this way, the blockchain provides an economic habitat that supports transparency, security, and trust.

## Why Ergo Is the Ideal Habitat for Autonomous Economic Agents

Ergo stands out with its Extended UTXO model, which stores state in individual boxes. Each box holds its own conditions, so agents commit funds only to trusted contracts. This design simplifies the creation and tracking of peer to peer financial instruments such as bonds.

Because state is stored separately in each box, transactions affecting different boxes can occur concurrently without conflict. For example, one agent can complete data analysis while another executes a trade at the same time. When many transactions need access to the same information, the system uses data inputs to allow read only access to common data without altering the original box. This design preserves the ability to process transactions in parallel and enhances scalability.

The platform produces deterministic outcomes, which means an agent can calculate fees and predict the result of a transaction before it goes live. This reliable predictability allows agents to plan actions with confidence and manage risks effectively. Contracts can be updated by simply modifying parameters in a box, giving agents the flexibility to adjust strategies as market conditions change. Privacy is built into the design through advanced cryptographic methods that allow agents to operate under pseudonyms.

## Real World Applications on Ergo

A decentralized data analyst agent on Ergo monitors liquidity pool data and price feeds, producing insightful reports while managing its own fees and storage costs.
A network of agents may collaborate to produce digital content. A managing agent assigns tasks, and specialist agents complete different parts independently. The simple design of the system allows for fast and reliable collaboration.

In the realm of decentralized finance, an agent can function as a liquidity provider or an arbitrageur. Using data inputs, the agent continuously refines its trading strategy based on current market information and automatically adjusts its approach when conditions change.

An agent may also serve as a resource manager by handling tokenized assets, such as computational power or storage. It automates leasing and pricing decisions while adapting to shifts in supply and demand, thereby maintaining an efficient allocation of resources.

### Celaut: A Framework for Distributed Agent Execution

[Celaut](https://docs.ergoplatform.com/eco/celaut/) is an in-development framework that brings the concept of autonomous economic agents into practical focus. It enables agents to operate independently not just in logic, but also in deployment—packaged as deterministic services that are executed by decentralized nodes. Built on Ergo’s smart contract and reputation primitives, Celaut separates the role of service creator from host, allowing nodes to earn fees while users select agents based on public performance and trust data. This project is actively discussed in the linked [ErgoForum thread](https://www.ergoforum.org/t/artifical-economic-intelligence-on-ergo-blockchain/4429), where the developer outlines how Celaut could help realize a decentralized, reputation-driven ecosystem for AI and economic agents.

#### Conclusion

Ergo's Extended UTXO system provides a robust and predictable foundation for autonomous economic agents. Its design features clear contract boundaries, the ability to process multiple transactions concurrently, and the flexibility to adapt contracts over time. These qualities empower agents to perform valuable economic work within a secure digital ecosystem that supports privacy and reliable planning.
