Curious about building on #LightningNetwork. Check out this guide bmancini55.github.io/building-light…

@danielvf Some additional color... To protect against ECDSA malleability, low-s sigs are often used (required for sigs the LN protocol for example). Low-s was originally proposed in BIP146. But with Schnorr sigs this malleability goes away entirely!

TLDR: Never use a signature as a key on a mapping! Know that there can be multiple valid signatures for the same message. 5/5

Here’s how signature malleability attacks work. Two attacks. If a user signs the same message multiple times, they get a different signature each time. If your code uses a signature as an identifier for blocking actions, users can repeat that action. 1/3

@jpjednorski @kodylow I’ve been working on this guide that builds a few applications from scratch. bmancini55.github.io/building-light…

Recently came across this from @kodylow @KodyLow/Base58-A-Tour-Of-Core-Lightning?v=1" target="_blank" rel="nofollow noopener">replit.com/@KodyLow/Base5… What other resources are out there for learning to build on the #bitcoin lightning network?

1/ There are no other constitutional rights in substance without freedom to transact Being meaning to write this for 6 months, but the Canadian response to the trucker protests is illustrating this so vividly, that today is the day.

If you don't, I encourage you to learn about why Bitcoin uses energy, the economics of mining, and most importantly to think bigger than your personal experience with money.

You should believe this too.

As Bitcoin energy FUD heats up again (pun intended) I am particularly concerned about its long term impact.

If you're looking to learn more about Taproot, I highly recommend this fantastic Workshop: github.com/bitcoinops/tap…
