使用BITVMX升级比特币的智能合同功能

BITVMX代表了比特币的智能合同能力的重大升级，实现通用计算和支持高级应用程序

In the constantly evolving landscape of cryptocurrency, Bitcoin has emerged as a dominant force, renowned for its robust security and vast user base. However, despite being the first cryptocurrency, Bitcoin's lack of smart contract capabilities has been a subject of discussion. In contrast, Ethereum, the second-largest cryptocurrency, is widely recognized for its advanced smart contract technology, which forms the foundation for diverse decentralized applications (DApps).

在不断发展的加密货币景观中，比特币以其强大的安全性和庞大的用户群而闻名，比特币成为了主导力量。但是，尽管是第一次加密货币，但比特币缺乏智能合同功能一直是讨论的主题。相比之下，以太坊是第二大加密货币，以其先进的智能合同技术而广受认可，该技术构成了分散应用程序（DAPPS）的基础。

Now, in a significant development, BitVMX, an upgrade to the BitVM programming environment, is poised to introduce general-purpose computation to Bitcoin's base layer, adjusting the virtual CPU model and introducing support for zero-knowledge SNARK proofs. This upgrade, which does not alter the consensus protocol, expands Bitcoin's programmability to levels comparable to Ethereum, opening up a new chapter in cryptocurrency innovation.

现在，在重大的开发中，BITVMX是对BITVM编程环境的升级，有望将通用计算引入比特币的基础层，调整虚拟CPU模型，并引入对零知识的Snark证明的支持。此升级不会改变共识协议，将比特币的可编程性扩展到与以太坊相当的级别，开辟了加密货币创新的新章节。

As reported by blog.bitfinex.com, BitVMX, an upgrade to the BitVM programming environment, is bringing general-purpose computation to Bitcoin's base layer without any changes to the consensus protocol.

正如Blog.bitfinex.com报道的那样，BITVMX是对BITVM编程环境的升级，正在将通用计算带到比特币的基础层，而无需对共识协议进行任何更改。

This upgrade to the programming environment developed by the Rootstock team introduces a virtual CPU model that can execute and verify complex programs, including SNARK proofs, through an optimistic verification method. It builds on the original BitVM, which was designed to introduce smart contract-like functionality to Bitcoin without modifying the consensus protocol.

Rootstock团队开发的编程环境的升级是引入了一个虚拟CPU模型，该模型可以通过乐观的验证方法执行和验证复杂程序（包括Snark证明）。它建立在原始的BITVM上，该BITVM旨在将类似于智能合约的功能引入比特币，而无需修改共识协议。

Can execute and verify programs up to 100K in assembly code.

可以在汇编代码中执行和验证多达100K的程序。

“This allows for the verification of SNARK proofs directly on Bitcoin, enhancing privacy-preserving applications and trust-minimized systems. Developers can compile ZK proof verifiers into BitVMX-compatible code for on-chain verification, significantly expanding the potential for privacy tools and scalable rollups.”

“这允许直接在比特币上验证SNARK证明，从而增强隐私保护应用程序和信任最小化的系统。开发人员可以将ZK证明验证器编译为与BITVMX兼容的代码，以进行链验证，从而显着扩展了潜在的隐私工具和可扩展的汇总和可扩展的汇总。”

What Can BitVMX Add to Bitcoin’s Smart Contract Ecosystem?

The BitVMX upgrade for the Rootstock Bitcoin sidechain marks a significant step forward in enhancing Bitcoin’s programmability. By enabling the execution and verification of complex computations like zero-knowledge SNARK proofs, BitVMX facilitates a more advanced blockchain application environment. The upgrade utilizes a virtual CPU model that supports general-purpose computation through architectures like RISC-V. This approach allows computations to be challenged only when necessary, minimizing the on-chain load and enhancing scalability without risking Bitcoin’s base layer.

dootstock比特币Sidechain的BITVMX升级标志着增强比特币的可编程性迈出的重要一步。通过启用和验证复杂的计算，例如零知识的snark证明，BITVMX促进了更高级的区块链应用程序环境。升级利用了通过RISC-V等体系结构来支持通用计算的虚拟CPU模型。这种方法只能在必要时挑战计算，从而最大程度地减少链上的负载并增强可扩展性，而不会冒着比特币的基础层的风险。

BitVMX's challenge-response protocol uses hash chains to validate execution traces, simplifying the verification process and reducing computational overhead. This innovation makes it feasible to build rollups and sidechains on Bitcoin, with message linking using one-time signature schemes ensuring state preservation across transactions. This design enables the creation of Bitcoin-based systems with flexibility comparable to Ethereum, varying the rollup and sidechain technology used based on application needs.

BITVMX的挑战响应协议使用哈希链来验证执行跟踪，简化验证过程并减少计算开销。这项创新使在比特币上构建汇总和侧链机构可行，并使用一次性签名方案链接消息，以确保跨交易中的状态保存。该设计使创建基于比特币的系统具有与以太坊相当的灵活性，从而根据应用需求改变了使用的汇总和Sidechain技术。

However, despite the potential of smart contracts, their integration into Bitcoin has been a gradual process due to the cryptocurrency's decentralized nature. Any changes to Bitcoin's scripting language require consensus among a large majority of nodes, which can be a slow and complex procedure.

但是，尽管有智能合约的潜力，但由于加密货币的分散性质，它们与比特币的集成一直是一个逐步的过程。对比特币脚本语言的任何更改都需要在大多数节点之间达成共识，这可能是一个缓慢而复杂的过程。

To overcome this challenge, BitVMX maintains compatibility with Bitcoin's existing scripting language, allowing for the incremental introduction of new capabilities. Moreover, BitVMX's modular architecture enables developers to select and combine components as needed, fostering an ecosystem of specialized applications.

为了克服这一挑战，BITVMX保持与比特币现有的脚本语言的兼容性，从而可以增量引入新功能。此外，BITVMX的模块化体系结构使开发人员能够根据需要选择和组合组件，从而促进专用应用程序的生态系统。

What Kind of Additional Programmability or Capabilities Can BitVMX Users Expect?

Expanding on Bitcoin's programmability, BitVMX introduces smart contract-like functionality without altering core consensus rules. This allows for the verification of zero-knowledge proofs directly on Bitcoin, enhancing privacy-preserving applications and trust-minimized systems. Developers can compile ZK proof verifiers into BitVMX-compatible code for on-chain verification, significantly expanding the potential for privacy tools and scalable rollups.

BITVMX扩展了比特币的可编程性，在不更改核心共识规则的情况下引入了类似智能合约的功能。这允许直接在比特币上验证零知识证明，从而增强了隐私保护应用程序和信任最少的系统。开发人员可以将ZK证明验证器编译到与BITVMX兼容的代码中，以进行链上验证，从而大大扩展了隐私工具和可扩展汇总的潜力。

Additionally, BitVMX enables the creation of decentralized bridges and sidechain communication mechanisms. Rootstock plans to develop the “Union Bridge” using BitVMX to create a trust-minimized bridge between Bitcoin and the Rootstock sidechain. This facilitates seamless asset transfers and multi-chain applications while preserving Bitcoin's decentralization.

此外，BITVMX可以创建分散的桥梁和侧chain的通信机制。 Rootstock计划使用BITVMX开发“联合桥”，以在比特币和砧木Sidechain之间创建一个信任最小的桥梁。这有助于无缝资产转移和多链应用，同时保留比特币的权力下放。

Overall, BitVMX transforms Bitcoin from sound money into a broader computational substrate, encouraging an ecosystem of experimentation and specialization. Its modular architecture supports a wide array of advanced DApps, from complex financial contracts to decentralized oracles, all within Bitcoin's secure and decentralized framework.

总体而言，BITVMX将比特币从声音货币转变为更广泛的计算基板，鼓励了实验和专业化的生态系统。它的模块化体系结构支持各种高级DAPP，从复杂的金融合同到分散的甲壳，都在比特币的安全和分散的框架内。
