TypeScript | 블록체인 | 블록 만들기(1)

먼저 블록 구조를 만들어보자. Block 클래스를 만들어준다.

 

index.ts

class Block {
    public index: number;
    public hash: string;
    public previousHash: string;
    public data: string;
    public timestamp: number;
    constructor(
        index: number,
        hash: string,
        previousHash: string,
        data: string,
        timestamp: number
        ) {
        this.index = index;
        this.hash = hash;
        this.previousHash = previousHash;
        this.data = data;
        this.timestamp = timestamp;
    }
}

export {};

 

 

인스턴스를 만들어준다.

 

index.ts

class Block {
    public index: number;
    public hash: string;
    public previousHash: string;
    public data: string;
    public timestamp: number;
    constructor(
        index: number,
        hash: string,
        previousHash: string,
        data: string,
        timestamp: number
        ) {
        this.index = index;
        this.hash = hash;
        this.previousHash = previousHash;
        this.data = data;
        this.timestamp = timestamp;
    }
}

const TeepoBlock: Block = new Block(0, "20202020202", "", "Hello", 123456);

export {};

 

 

 

블록체인을 만들어준다. 블록체인이랑 블록들이 배열로 연결된 형태이다.

index.ts

class Block {
    public index: number;
    public hash: string;
    public previousHash: string;
    public data: string;
    public timestamp: number;
    constructor(
        index: number,
        hash: string,
        previousHash: string,
        data: string,
        timestamp: number
        ) {
        this.index = index;
        this.hash = hash;
        this.previousHash = previousHash;
        this.data = data;
        this.timestamp = timestamp;
    }
}

const TeepoBlock: Block = new Block(0, "20202020202", "", "Hello", 123456);

let blockchain: Block[] = [TeepoBlock];

console.log(blockchain)

export {};

 

tsc-watch 를 보면

 

완벽하게 블록이 들어간 것을 확인할 수 있다.
