Difference between smart-contracts and nodes.
In this post we will tell you about the difference between a node and a smart contract.

A node is any computer that is connected to a blockchain #network. Simply put, this is the point at which messages can be created, received, or transmitted. For a bitcoin network, for example, there are full nodes, #supernodes, miner nodes, and an SPV client.

Smart contracts are #computer data transfer protocols that use mathematical algorithms to automatically complete a transaction after meeting established conditions and complete process control. The #protocol is used to enter all the terms of the contract concluded between the parties to the transaction in the blockchain. Obligations of participants are provided in the smart contract in the form of โif-thenโ (for example: โif Party A transfers money, then Party B #transfers the rights to the apartmentโ). Once these conditions are met, the smart contract independently performs the transaction and ensures that the agreement is respected.
โ
โ๏ธ Thus, the smart contract is the action that takes place, and the #node is the place where this action takes place.

โ๏ธ The distinctive mechanism is as follows: only the hash of one event (#transaction) is recorded in the block, and it cannot be changed. Thus, all kinds of collisions are swept aside. In addition to recording the event hash into the block, when forming a new one, the entire hash of the previous block and + integer value is taken (we put the sequential block number in front of the block). There is a main chain of blocks โ Master_Chain, which contains only the hash of a block of lower and side smart contracts.
โ
โ๏ธ In parallel with the main Master_Chain, various independent chains are formed โ these are smart contracts that organize the three-dimensional distribution, for example:
- first smart contract โ generation of tokens;
- second smart contract โ sale of goods through the store;
- third โ a crypto #exchange;
- fourth โ delivery of goods, etc.
โ
โ๏ธ Thus, the organization of chains of smart contracts and the main Master_Chain leads to a four-dimensional model of the organization of distribution of #blocks.
