Simple Blockchain data indexing with TrueBlocks
Blockchain is a type of a shared database that differs from a typical database in the way it stores information. A blockchain is a growing list of records, also called blocks, that are linked together using the latest cryptography technology. In general, each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.
For example, the transaction data in a Bitcoin Block contains information about the Sender, Receiver and the number of bitcoins to be transferred.
A blockchain database utilizes blockchain technology to create an immutable ledger of transactions. The first block in the chain is called the Genesis block. As each new block or transaction is recorded, it is added to the previous one to form a chain of data records or a blockchain. As a result, a blockchain contains every transaction recorded since the ledger was started. Blockchain data in a crypto space tends to be represented as a Merkle tree.
