The Bitcoin Blockchain History

The Bitcoin blockchain was born in 2009, by a pseudonym Satoshi Nakomoto.

Take a look here at the first block(block 0) or the “genesis block” of Bitcoin blockchain.

There is one transaction in this block to Satoshi Nakomoto’s address. Interestingly Satoshi’s account address has never been used to transfer out money so we don’t know if it’s intentional, or if the private key lost?

Now look at another block, this one has 1660 transactions.

A transaction is a record of transfer of bitcoins from one address to another.

Membership/Transaction Signing: #

A transaction is always digitally signed by the ‘from’ an account holder to ensure that only the owner of account can perform a transaction using their balance.

In Bitcoin, anyone can generate an asymmetric keypair and start transacting on the Bitcoin blockchain.
