A blockchain service is a technology that uses a distributed ledger to record and validate transactions across a network of computers, making it difficult for any one person or group to tamper with the data. It is often used to create secure and transparent systems for things like financial transactions, supply chain management, and voting systems. The most well-known example of a blockchain(https://web3acad.com/blockchain-expert-bootcamp/) service is the Bitcoin cryptocurrency, but the technology has many potential uses beyond that.
