The term "smart contract" can be traced back to at least 1995 and was proposed by the prolific interdisciplinary legal scholar Nick Szabo. He mentioned the concept of smart contract in several articles published on his website. His definition is as follows:
"a smart contract is a set of promises defined in digital form, including the agreements on which the contract participants can implement these commitments."
Let's explore the meaning of his definition in more detailcommitment
a set of commitments refers to the (often mutual) rights and obligations agreed by contract participants. These commitments define the nature and purpose of the contract. Take a sales contract as a typical example. The seller promises to deliver the goods and the buyer promises to pay a reasonable price
digital form
digital form means that contracts have to be written into computer-readable code. This is necessary, because as long as the participants reach an agreement, the rights and obligations of smart contract establishment are executed by a computer or computer network
(1) when will the parties to the smart contract reach an agreement? The answer depends on the specific smart contract implementation. Generally speaking, the contract is discovered when the parties are committed to the execution of the contract by installing the contract on the contract host platform (2) the real meaning of "execution" also depends on implementation. Generally speaking, implementation means active implementation through technical means(3) computer readable code
in addition, the specific "digital form" required by the contract is very dependent on the agreement that the parties agree to use
protocol
protocol is technical implementation, on this basis, the contract commitment is realized, or the contract commitment is recorded. Which agreement to choose depends on many factors, the most important of which is the nature of the assets being traded ring the performance of the contract
again, take the sales contract as an example. Suppose that the participants agree to pay in bitcoin. The chosen protocol will obviously be bitcoin protocol, on which the smart contract will be implemented. Therefore, the "digital form" that the contract must use is bitcoin scripting language. Bitcoin scripting language is a non Turing complete, imperative, stack based programming language, similar to forth

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved" blockchain technology professional "pilot workstation of" smart learning workshop 2020 Xueshuo innovation workstation "launched by the school planning, construction and Development Center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system
Electronic contract itself is a kind of electronic data, which has security defects such as easy to tamper and delete, which is not concive to the long-term development of the service. In order to ensure the legal effect of the electronic documents and electronic contracts signed by users on the electronic contract platform, it is necessary to deposit the whole process of electronic contract signing
in the application of "legal chain" based on blockchain certificate keeping technology, the platform will archive the key links of electronic contract signing, and store the key information and data in the whole blockchain, so as to realize the whole process of electronic contract certificate keeping
in-depth study of its implementation principle, blockchain uses cryptography algorithm, specially designed data structure and multi-party consensus algorithm to solve the consistency, reliable storage and anti tampering problems of multi-party transaction records by machine algorithm, which has a strong natural relationship with electronic data storage
First of all, the electronic contract signing records are stored in a shared account book jointly maintained by multiple parties, which can not be tampered with, denied or lostsecondly, the text and elements of the electronic contract are encrypted, including the participants of the electronic contract. Only the participants can decrypt and view the data to protect the privacy of the parties
thirdly, the machine strictly implements the pre-defined rules (smart contract), and no longer relies on a single agreement with a third party. KYC service based on blockchain automatically checks and verifies the validity and identity of certificates, and ensures the authenticity of participants' identities on the basis of privacy
at present, the electronic contracts signed on our electronic contract platform have realized the distributed storage of digital fingerprints of electronic documents through blockchain technology, which further strengthens the legal effect of the platform's electronic contracts
Through the deep use of cryptography algorithm, specially designed data structure and multi-party consensus algorithm, blockchain uses machine algorithm to solve the consistency, reliable storage and anti tampering problems of multi-party transaction records, which has a natural strong correlation with electronic data storage
at present, the electronic contract signed on the advanced electronic contract platform has realized the distributed storage of digital fingerprints of electronic documents through the blockchain technology, which further strengthens the legal effect of the platform electronic contract
Anyone can own bitshares by investing in bitshares PTS and bitshares AGS. AGS (angel shares) is a share of angel investment fund, which is used to support the research, development and creation of technologies related to bitstocks. A total of 10000 AGS will be given to those who donate Angel funds on the same day according to the proportion of donation to the donation on the same day. Bitshares PTS is a clone of bitcoin that allows you to mine and trade your support for the bitshares ecosystem. Bitshares AGS and bitshares PTS both contain a social consensus, that is, in the future, all bitshares blockchains should allocate at least 10% of each to AGS and PTS shareholders in Genesis block to give back their support to the ecosystem of bitshares
through consensus algorithm, the user data can be updated synchronously among judicial nodes such as notary office, Arbitration Commission, Internet court, judicial identification Institute and right institution on the security chain, so that each node on the security chain can realize real-time exchange of data and information, and effectively improve the judicial credibility of the blockchain data
based on the mode of "blockchain + judicature + application", e-security deeply arranges e-signing, and helps enterprises transfer traditional offline paper contracts to online signing by means of professional underlying data storage capability, full evidence chain technology and post signing judicial services, providing real name authentication, E-contract, signature management and other services
, the use of blockchain technology for the original works of online right confirmation, infringement detection and infringement forensics, as well as online right registration and other intellectual property protection services. It provides online arbitration filing application, agent execution, direct evidence to arbitration commission and other services for enterprises and indivial users. At the same time, it can also provide the notary office with the construction of Internet notary system, notary intelligent terminal and corresponding customized services, and help the notary office to comprehensively transform and upgrade its business. At present, it has successfully provided judicial services such as Internet notarization system construction for many notary offices. And other application scenarios, lead the blockchain to different instries and fields, provide full supporting solutions, and accelerate the rapid implementation of blockchain in the whole instry. As the cornerstone of digital economy, blockchain technology plays an important role. Through "blockchain +" to quickly complete the transformation and upgrading, release new momentum for the development of digital economy.
