Governments have "Chainalysis" tools to follow Bitcoin transactions. Let's build an open-source tool for everybody to have a "Chainalysis" tool!
Bitcoin Flow is a visual graph-based UI for Bitcoin Transactions - where each node represents a transaction with input/output edges connected to other transactions. You can enter a specific txids, addresses and xpubs to see their transactions, label them, etc.
I'll be happy to get help integrating this project on personal nodes, and extending the tool to be able to build/display chains of PSBTs.

Your email remains the same, but your lightning address might not.
This creates a frustration when you need to switch to a new lightning wallet - you have to tell everyone to use your new lightning address instead of your old lightning address.
If only Email providers could turn your email address to a lightning address...
ln2.email turns your email address @.com to asimilarly-looking lightning address @.com.ln2.email, with a redirection that you control.

Many less-technical Bitcoiners need a recovery mechanism that doesn't require them to switch to a multisig/miniscript wallet. Timelock Recovery is a solution based on 2 pre-signed transactions - one that keep the Bitcoin on the same wallet, and another that moves it to a second wallet after a relative-locktime (nSequence). Pre-signed transactions are safer to save online, but obviously have some disadvantages.
We will talk about how to create, backup, monitor and execute Timelock Recovery plans via the RITREK Android app.
