Transactions

At its heart, the Bitcoin protocol consists of transactions. All these transactions are completely public on the blockchain, which means that anyone can see which addresses sent bitcoins to which addresses. If some of these addresses are linked to real world identities, it can reveal who transacted with whom ‒ or what for. This is at odds with privacy and – in particular ‒ fungibility.

To enhance privacy, it is possible to hide the amount of bitcoins transacted. An early version of this concept, then referred to as “bitcoins with homomorphic value,” was first proposed in 2013 by hashcash inventor and current Blockstream president Dr. Adam Back.
