The development of Industry 4.0, smart contract is one of critical application in the blockchain platform, which is the remove of intermediary services to facilitate transactions directly between stakeholders, in which the trust between stakeholders is guaranteed by a blockchain system. However, existing solution of automated execution of smart contract is simply given by the prescribed program code. This solution results in two negative effects: the contract is not human-readable and difficult to modify; contracting parties cannot collaboratively draft the contract and cannot assure the shared consent of the contract. Therefore, we will introduce a brand-new solution of smart contract, called Intelligible Description Language Contract (IDLC). It will allow contracting parties to draft a contract collaboratively just as working on text editor with a supportive tool of concept disambiguation through Supervised Sentence Contract (SSC). SSC consists of Machine Natural language (MNL) via Semantic input method (SIM). SIM provides a method of supervised contract obligation creation. MNL provides the capability of universal computer-understandability. Meanwhile, in the complex contract transactions and management, especially in supply chain management, a chained evidence sequence is designed to avoid collusion. IDLC is a first paradigm that bridges the traditional contract based on natural languages and the smart contract based on blockchain platform.

工业4.0的发展，智能合约是区块链平台中的关键应用程序之一，它是去除中介服务以促进利益相关者之间直接交易的方法，其中利益相关者之间的信任由区块链系统保证。但是，现有的自动执行智能合约的解决方案仅由规定的程序代码给出。该解决方案导致两个负面影响：合同不易阅读且难以修改；签约方不能共同起草合同，也不能保证合同的共同同意。因此，我们将介绍一种称为“智能描述语言合同（IDLC）”的全新智能合同解决方案。它将使合同方可以像在文本编辑器上工作一样，通过监督句子合同（SSC）来支持概念歧义消除工具，共同起草合同。SSC通过语义输入法（SIM）包含机器自然语言（MNL）。SIM提供了一种监督合同义务创建的方法。MNL提供了通用的计算机可理解性。同时，在复杂的合同交易和管理中，特别是在供应链管理中，设计了链式证据序列以避免串通。IDLC是将基于自然语言的传统合同与基于区块链平台的智能合同联系起来的第一个范例。SSC通过语义输入法（SIM）包含机器自然语言（MNL）。SIM提供了一种监督合同义务创建的方法。MNL提供了通用的计算机可理解性。同时，在复杂的合同交易和管理中，特别是在供应链管理中，设计了链式证据序列以避免串通。IDLC是将基于自然语言的传统合同与基于区块链平台的智能合同联系起来的第一个范例。SSC通过语义输入法（SIM）包含机器自然语言（MNL）。SIM提供了一种监督合同义务创建的方法。MNL提供了通用的计算机可理解性。同时，在复杂的合同交易和管理中，特别是在供应链管理中，设计了链式证据序列以避免串通。IDLC是将基于自然语言的传统合同与基于区块链平台的智能合同联系起来的第一个范例。
