A blockchain data structure for Node.js! 🚀
const { Blockchain } = require("@anychain/core");
const blockchain = new Blockchain();
const shipments = [
{
trackingId: 42,
latitude: 40.758895,
longitude: -73.985131
}
];
blockchain.add(shipments);import { Block, Blockchain } from "@anychain/core";
interface Shipment {
trackingId: number;

longitude: number;
}
const shipments: Shipment[] = [
{
trackingId: 42,
latitude: 40.758895,
longitude: -73.985131
}
];
const blockchain: Blockchain<Shipment[]> = new Blockchain<Shipment[]>();
const latestBlock: Block<Shipment[]> = blockchain.add(shipments);yarn add @anychain/core
# or
npm install --save @anychain/corePass an optional existing chain to the constructor.
Adds a new block with the given data to the blockchain.
Overwrite the current chain with a more recent one. Returns true when the update was successful.
