-Lightning implementations user friendly

Working on projects related to privacy enhancements in the Bitcoin ecosystem is important. Here are some cool examples of things you can build to improve the privacy of Bitcoin transactions:

CoinJoin Implementations: CoinJoin is a technique that allows multiple users to combine their Bitcoin transactions into a single transaction, making it more difficult to trace the flow of funds. You can develop CoinJoin implementations, either as standalone tools or as part of existing wallets, to enhance transaction privacy for Bitcoin users.

CoinSwap Services: CoinSwap is another privacy-enhancing technique that allows users to exchange their bitcoins with others in a way that breaks the link between the original and swapped coins. You can build CoinSwap services that enable users to exchange their coins privately and securely, preserving their privacy on the Bitcoin network.

Chaumian CoinJoin: Chaumian CoinJoin is an improved version of the CoinJoin concept that utilizes blind signatures to provide better privacy guarantees. You can develop libraries or protocols that implement Chaumian CoinJoin, allowing developers to integrate this advanced privacy technique into their Bitcoin applications. Cashu and Fedi are doing great things with Chaumian e-cash currently.

Confidential Transactions: Confidential Transactions is a cryptographic protocol that conceals the transaction amounts in Bitcoin, while still maintaining the ability to verify the overall transaction's validity. You can work on implementing confidential transactions in Bitcoin, allowing users to transact with enhanced privacy by hiding the amounts involved in their transactions.

Coin Selection Algorithms: Coin selection algorithms determine which bitcoins from a user's wallet should be used for a specific transaction. You can develop improved coin selection algorithms that prioritize privacy, ensuring that transactions are composed in a way that minimizes the traceability of funds and avoids linking addresses unnecessarily.

Privacy-Focused Wallets: Build privacy-focused Bitcoin wallets that integrate various privacy-enhancing features, such as CoinJoin, Tor network integration, address reuse prevention, and more. These wallets can offer users a seamless and privacy-preserving experience while transacting with Bitcoin.

Privacy Education and Research: Another valuable contribution to privacy enhancements in the Bitcoin ecosystem is creating educational resources and conducting research on privacy-preserving techniques. This can involve writing articles, publishing papers, or organizing workshops to educate the community about the importance of privacy and the available tools and techniques.

Good luck contributing having experienced devs is always valuable! Cheers.

I think the answer can only be found by finding product person(s) to collaborate with through discussions with users to find their most critical problems

If I was elite and skilled in Rust I'd either contribute to the breez SDK or leverage it into building something that complemented one of my other strengths

My failed bitcoin startup, I suppose

Better obfuscating of transactions and ownership that rivals monero.

CashuBTC - the team is great!

A third layer for lightning that automatically keeps pools of nodes liquid. Basically an opt-in system that shares channel balances to execute intelligent rebalances rather than the brute force guessing we have now

More UIs

I will code the "function" for subsidy and reward (halving) for Bitcoin miners
