If this tweet is pinned, I'm taking a break from Twitter. I'm probably still reading and replying on Nostr, and you can always contact me directly by email (see the website on my profile).

this is so cool 🙌🏽 taxes have been a huge burden to me over the past several years of working on grants. some initial mistakes have taken years to dig out of. this is an amazing offering.

Today there's only a small number of people who have enough interest in cluster mempool to read this. But anyone who wants to understand how Bitcoin Core works for years to come will find this document invaluable.

Over the past few weeks I’ve been taking a bit of time to brush up on all the tech updates in the #Bitcoin world. At this point the ecosystem is so big it’s not realistic to expect yourself to stay up to date with all of it. But, if you’d like to try anyhow, there are some great resources out there! First is of course @bitcoinoptech with @murchandamus, @bitschmidty, @hrdng and more. They publish a weekly newsletter and summary discussion. If you’re only going to do one thing to stay informed on Bitcoin tech this should be it! Just an hour a week will keep you sounding like you know what you’re talking about 😜 For deep dives on specific topics the Bitcoin Explained series with @AaronvanW and @provoost by @BitcoinMagazine is super helpful. And if you prefer to dive into mailing list and stackexchange discussions the Bitcoinsearch bot will find you what you’re looking for! Thanks y’all for making such fabulous resources 🙏

A DoS vulnerability affecting lnd versions *before* 0.17 (released ~9 months ago) has been disclosed: delvingbitcoin.org/t/dos-dis… if your node is updated to either 0.17.x or 0.18.x then you're safe ✅ if unable to update, then setting --rejecthtlc can mitigate the DoS vector
