One of blockchains and cryptocurrencies’ most important advantages can be its largest weak spot. When you invest in public open-source blockchains by mining or buying cryptocurrencies and retailer it in your cryptocurrency wallet , solely you management your money. The Ethereum network is a public, decentralized peer-to-peer network. Like Bitcoin, it uses nodes and permits customers to send and receive cryptocurrency—in this case, Ether.

Transactions on the blockchain network are approved by a network of hundreds of computer systems.
