The blockchain is a distributed database that allows for secure, transparent and tamper-proof record-keeping. It is the underlying technology behind cryptocurrencies like Bitcoin and Ethereum.
The blockchain is managed by a decentralized network of computers, each of which holds a copy of the blockchain. The computers in the network validate transactions and add new blocks to the chain.
The person or group of people who created the blockchain technology is unknown. The original Bitcoin white paper was published anonymously under the pseudonym Satoshi Nakamoto.
