1. Understand blockchain and what is a smart contract

A smart contract is a contract that does not require a third party such as a notary or public official to verify, facilitate or execute !

Literally means you can conduct fast, reliable and trustworthy transactions with any third party, without the constraints of ordinary contracts

Healthcare

Who has access to my patient data? Is my digital patient record safe? and many other issues arise from having digital patient records. As we learned, if only a limited number of people need access for a limited time, keep your profile with you at all times and only have access if you allow doctors access.

Highly regulated, such as drug storage and distribution.

2. Essential characteristics of blockchain smart contracts

Essential characteristics of blockchain smart contracts: decentralization.

Some of the main advantages of using smart contracts include greater efficiency when processing documents. This is thanks to its ability to employ a fully automated process that does not require any human involvement, as long as the requirements listed in the smart contract code are met.

The result is that time is saved, costs are reduced, transactions are more accurate and cannot be changed. Additionally, smart contracts remove any third-party interference, further enhancing the decentralization of the network.

(2)mmm Blockchain Smart Contract Extended Reading:

Smart contracts can only use digital assets, and problems will arise when connecting real assets and the digital world. Finally and most importantly, smart contracts lack legal supervision and are only subject to the obligations agreed in the code. The lack of legal regulation may lead some users to be wary of transacting online, especially if it is significant.

The advantages of using smart contracts are more efficient processing of transactions, irreversible, secure transactions and fully automated processes. On the other hand, the disadvantages are the lack of legal supervision, human errors and difficulties in implementation.

3. What is a smart contract in blockchain technology

Chongqing Jinwowo analyzes smart contracts as follows:

Smart contracts are a type of smart contract that can only be passed through A new technology that can only be achieved by blockchain. Ordinary, standard contracts cover the terms of an agreement between parties and are often enforced by law; smart contracts are digital, stored on the blockchain, and use encrypted code to enforce the agreement.

In other words, smart contracts are simply software programs that, like all programs, execute exactly as the programmer intended. Smart contracts are like programming applications: "Once it appears, execute it."

4. What is a smart contract in blockchain technology

Smart contracts can be simply understood as A paragraph is written on the blockchainThe code is event-driven, has dynamic status, is recognized by multiple parties, and can automatically process on-chain information according to preset conditions. Once an event triggers the terms in the contract, the code will be automatically executed. The biggest advantage of smart contracts is to use program algorithms to arbitrate and execute contracts on behalf of humans.
Smart contracts are contracts that use computer language instead of legal language to record terms. Once written, they can be trusted by users. The terms of the contract cannot be changed, so the contract is immutable. The procedure will be executed when the conditions are met, without human interference, ensuring absolute fairness and justice.
3 technical characteristics of smart contracts
●Data transparency
All data on the blockchain is open and transparent, so the data processing of smart contracts is also open and transparent, and any party can run it can view its code and data.
●Cannot be tampered
All data in the blockchain itself cannot be tampered with, so the smart contract code deployed on the blockchain and the data generated by its operation are also non-tamperable. Nodes running smart contracts do not have to worry about other Nodes maliciously modify code and data.
●Permanent operation
The nodes supporting the blockchain network often reach hundreds or even thousands. The failure of some nodes will not cause the smart contract to stop. Its reliability is theoretically close to permanent operation. In this way This ensures that smart contracts can be as valid as paper contracts at all times.

5. What is the principle of smart contracts under blockchain technology

Jinwowo analyzes the principles of Xianlun smart contracts under blockchain technology as follows:

The principle of smart contracts is the link between points, which exists in physical and digital spaces, in the real world and the virtual world. It may exist in a certain space, or in two different spaces. These two The space has natural links, is distributed, and has no centralized existence;

The trust relationship is transformed into code through algorithms, the code forms a program, the program drives the link, and the trust link is In a system, after brother letter registration, registration, and transaction, all of this is done in the program, and everything is converted between 0 and 1; there is no authoritative source, no opinion leader;

This is a purely natural community, a decentralized community, collaborative, and its infrastructure is blockchain technology.

6. What is the role of smart contracts in blockchain technology

Smart contracts are one of the four core technologies in blockchain. This concept was first developed in 1994 , proposed by the well-known cryptologist Nick Szabo, has never been implemented due to technical and other reasons. Even today, smart contracts have been used in many applications on the Internet, such as automatic repayment, drone sales, etc. etc. Most of them are limited to smart contracts between individuals and institutions. There are almost no smart contracts between individuals. The reason is the "trust" issue. We will find that, as long as we talk about contracts, most of them are strangers who have this kind of demand, and it is also related to money. If we make an agreement without a third party as a guarantee, I will give the money I called you, but you broke the contract. What should I do if you don’t admit it? Therefore, smart contracts have never been popular among individuals. Later, with the emergence of blockchain, people found that blockchain is very consistent with smart contracts, because of many characteristics of blockchain, such as Decentralization, non-tamperability of data, etc. can solve the problem of trust between strangers from a technical perspective. This makes the large-scale application of smart contracts possible. The beginning of this stage is marked by the birth of Ethereum. . Based on the blockchain, Ethereum applies smart contract technology. Smart contracts enable Ethereum to achieve more functions. Smart contracts are a very important application, so slowly, smart contracts have become one of the core technologies of the blockchain.

7. Does blockchain 1.0 include smart contract technology?

Included. According to the relevant information of Blockchain 1.0, it can be seen that Blockchain 1.0 includes smart contract technology. In fact, in the blockchain 1.0 era, the blockchain technology used by Bitcoin already included the concept of smart contracts. It can be said that the introduction of smart contracts has made blockchain technology evolve into a force that drives the world.

8. What is blockchain smart contract payment?

Blockchain smart contract payment refers to transactions and non-transactions. The first thing to make clear is that blockchain smart contracts are not real contracts. According to the programmable characteristics of the blockchain, people can place contracts on the blockchain in the form of code and automatically execute them under agreed conditions, which is called a smart contract. It's just a broad definition. A smart contract is a piece of code involving assets and transactions. Only by putting it on the blockchain can we effectively prevent "piracy" and "tampering". In fact, before the emergence of blockchain, smart contracts did not receive much development.
As blockchain technology develops and matures, smart contracts will be very useful. Smart contracts are a new way for new participants to reach consensus. It does not depend on any organization or individual for its execution, it does it on its own, not even by default. Smart contracts will become the fundamental structure of the global economy. Anyone can use smart contracts to participate in economic activities without prior review and high upfront costs. In traditional contract making, people must choose trustworthy people and institutions, while smart contracts eliminate the necessary trust in third parties from many economic transactions.
With the emergence of virtual digital currency, blockchain came into being. In essence, blockchain is a decentralized database and distributed ledger technology, that is, data storage in distributed institutions. Compared with traditional centralized storage, decentralized storage makes supervision more open and transparent, avoiding risks such as tampering and forgery. Therefore, the application of blockchain in the field of electronic contracts adds security to the custody of electronic contracts.
Blockchain solves the authentication process during the use of electronic contractsStorage, credit enhancement, and authenticity authentication issues. Deposit receipts for electronic contracts are susceptible to security breaches through third parties, leading to data leaks. Deposit receipts are single, making it difficult to trace when problems arise. The platform also questioned the validity of the verification data. The application of blockchain technology can generate encrypted storage of data chains during the signing process of electronic contracts. Once the data on the chain is difficult to tamper with, the signing time and operation information can also be accurately recorded through time stamp technology, and the evidence chain can be saved and communicated with third-party institutions. Cooperate to ensure the security of electronic contract signing. After blockchain deposits and third-party institution deposits, the credibility of judicially adopted evidence is effectively improved, and forensic appraisal reports and notarization can be quickly applied for. At the same time, blockchain smart contracts also ensure the authenticity and reliability of the contract's authenticity. Ensure that electronic contracts have full legal effect
