Iron Fish is a decentralized, proof-of-work (PoW) based, censorship-resistant, and publicly accessible blockchain project. It is designed to support strong privacy guarantees on every transaction. Similarly to how the invention of the SSL/TLS layer in the '90s paved the way to e-commerce and benefited countless industries, we believe that privacy is a fundamental requirement to protect the user and expand the use of cryptocurrency.

We have designed Iron Fish to be a new cryptocurrency from the ground up to enable easy-to-use, fully-private payments by closely following the Sapling protocol. Every account is equipped with a view key to grant its holder read-only permission for the details of that account.

With this protocol, we are challenging previous patterns of full node usability. The Iron Fish networking layer supports WebRTC with WebSockets, making it trivial for all users to make a true P2P connection with no other setup requirements. Our first Iron Fish implementation is built such that it can be extended to run a full node directly in the browser in future iterations. And our focus is to lower the barrier to entry so that any person with a computer feels comfortable enough to run a full node.
