On the Bitcoin blockchain, only a user’s public key appears next to a transaction—making transactions confidential but not anonymous. In that sense, Bitcoin transactions are more transparent and traceable than cash because all of them are available for public view, unlike private cash transactions. But Bitcoin transactions also have an element of anonymity built into their design. It is very difficult to trace the transacting parties—i.e., the sender and recipient of the bitcoin—on the cryptocurrency’s blockchain.

As Bitcoin’s adoption has grown over the years, more people have likely begun wondering how Bitcoin works. Bitcoin is a decentralized cryptocurrency that operates on its own blockchain that is secured and run by a vast global network of participants.

The software validates the entire blockchain, which includes all bitcoin transactions ever.

Since old nodes will recognise the new blocks as valid, a soft fork is backward-compatible. This kind of fork requires only a majority of the miners upgrading to enforce the new rules. A hard fork is a protocol upgrade that is not backward compatible. This means every node needs to upgrade before the new blockchain with the hard fork activates and rejects any blocks or transactions from the old blockchain. The old blockchain will continue to exist and will continue to accept transactions, although it may be incompatible with other newer Bitcoin clients. A hard fork is a radical change to the protocol that makes previously invalid blocks/transactions valid, and therefore requires all users to upgrade. For example, if users A and B are disagreeing on whether an incoming transaction is valid, a hard fork could make the transaction valid to users A and B, but not to user C.
