Next Gen Sovereign Tech Stack
Citadel maintains a set of libraries and binaries for various Bitcoin protocols, aiming to enhance individual sovereignty in the new digital panopticon.
We focus on building protocols on top of Bitcoin and other sidechains/L2s that provide a bridge between unconnected layers like Bitcoin, Lightning, Ecash, Liquid, etc, without requiring a trusted third party. These protocols and tools allow more sovereign user access on these layers, reduce centralisation risks while also incentivising node-runners to put their stale liquidity at work to earn more sats.
Coinswap, being our first foundational protocol which facilitates the first btc<>btc perr-to-peer decentralised atomic swaps without trusted third parties. The market itself remains censorship-resistant as it's seeded in the Bitcoin blockchain. Anyone with access to a sovereign node can participate in the market.
While the core protocol only works on the Bitcoin blockchain, a generalised version of the protocol will be used to bridge between multiple layers—increasing liquidity flow across layers, increasing user sovereignty, reducing network centralisation, while also incentivising individual home node-runners.
