#Trump100Days is the first decentralized cryptocurrency. It can be sent from one person to another over the Bitcoin network in a peer-to-peer manner without the need for a third party. Transactions on the network are verified using cryptography and are recorded in a distributed ledger called the blockchain without a central authority overseeing it. Consensus among nodes is achieved using a resource-intensive mathematical process known as proof of work, which secures the Bitcoin blockchain. Mining consumes large amounts of electricity and has been criticized for the environmental impact of Bitcoin.
