The gas fee and the miner reward usually uses the native currency on the blockchain. In most cases, read transactions are free. You pay for the computer power you used with a gas fee. To complete the incentive system, each write transaction to the blockchain requires a gas fee, that's partly paid to the miners-the node operators that contribute the computing power on the blockchain. a miner, is rewarded for contributing the computing power to power the blockchain network. Why would you spend money and run a node of a blockchain? Each node operator, a.k.a. Once written with the consensus, the data is immutable.Ī blockchain is designed to be self sustainable through incentives.

Individual nodes may be out-of-sync at times but eventually update themselves with the consensus. When nodes contain different data, it is settled via a consensus protocol so all data will be the same across all nodes. Usually nodes are accessible programmatically through RPC (remote procedure calls). There are multiple nodes - each node is a computer system that runs an identical program and syncs the blockchain data at all times. The account owner should keep their private key secure at all times as once the private key is compromised, there is no way to lock down the account.Ī public blockchain is a distributed computer system connected by the internet. The private key enables you absolute control of your blockchain account, and you cannot change the private key, ever. a wallet address, and each address has a unique associated private key. An account on a blockchain consists of an address, a.k.a. What is a blockchain? Here's the answer for developers:Ī public blockchain is an open and autonomous distributed computer system built on incentives.Īnyone can access a blockchain through creating an account on the blockchain.
