Traffic over the Bitcoin network has always been unencrypted. Transactions and blocks are sent from node to node in plain sight, as are Bloom filters, which are often used by Simplified Payment Verification (SPV) nodes. All this data can, therefore, be seen by Internet Service Providers (ISPs), open-WiFi providers and anyone monitoring the Bitcoin network.

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.
The Lightning Network is probably the most highly anticipated technological innovation to be deployed on top of Bitcoin. The payment layer, first proposed by Joseph Poon and Tadge Dryja about a year ago, promises to support a virtually unlimited number of off-chain transactions among users, at nearly no cost – while leveraging the security offered by Bitcoin.
