The blockchain is like a full history of banking transactions. These transactions, usually include a “monetary” exchange represented in the crypto-currency specific to the blockchain carrying the transmission. Events are entered chronologically in a blockchain just the way bank transactions are. The “Blocks” themselves are similar to the concept of an individual bank statement.
A block is the ‘current’ part of a blockchain which records the most recent exchanges, transfers, communications etc… and once verified (by a recognized “miner”) goes into the blockchain ledger as a permanent entry. That verified ledger entry is then transmitted to each of the mining nodes. Each time a block gets completed, a new block is generated. There is a countless number of such blocks in the blockchain. So are the blocks randomly placed in a blockchain? No, they are linked to each other (like a chain) in proper linear, chronological order with every block containing a hash of the previous block.
Every time a block is finished, another block is generated. There are a countless number of such blocks in the blockchain each linked to each other in a linear, chronological order with every block containing a hash of the previous block.
The blockchain is a technological innovation of Bitcoin, but since that time has been recreated in many variations by other competing or complimentary venue’s. it stands as proof of all the transactions on the network.
Based on the Bitcoin protocol, the blockchain database is shared by all nodes participating in a system. The full copy of the blockchain has records of every Bitcoin transaction ever executed. It can thus provide insight about facts like how much value belonged a particular address at any point in the past.
The blockchain is thought by some to have problems with issues like storage and synchronization. This may be true, but our speculation is that human ingenuity will overcome any temporary shortfall, and in fact, many of the difficulties facing the Bitcoin chain have been dealt with by some of the smaller nimbler chains that others has introduced to the market. On an average, every 10 minutes, a new block is appended to the block chain through mining.
