Why

feels like threads is picking up steam again…

Just noticed this new slogan in the App Store 🥴

This is how I roll

Do you really need any other gizmo if you already have a Coldcard? 🤔

Woah there

Am I crazy or does this look like a phishing scam?

How does Blockstream normally release updates? Is that the right website?

Apologies in advance if this is FUD but just trying to play it safe

In the event of a sudden reorganization of the blockchain, several technical considerations would be warranted, reflecting the described scenario.

Waiting for 1000 confirmations before considering a transaction safely received: This depends on your risk tolerance. Historically, six confirmations have been considered secure, but a reorg of 1000 blocks would certainly challenge this assumption. Depending on the perceived risk of further hidden chain mining, waiting for a larger number of confirmations might be prudent, although 1000 might be excessive and hamper practical usability.

As a node runner, rejecting the new tip and keeping tabs on bitcoin-cli getchaintips: You could technically choose to reject the new chain, but this would place you on a fork that might have less mining power and thus be less secure. Regularly checking chain tips and being aware of the state of the network would be a standard best practice. Depending on your view of the legitimacy of the new chain, you might want to take additional steps, such as manually specifying preferred peers that follow the chain you trust.

As a miner, considering pulling out of mining pools or creating new ones: If you suspect that a mining pool was contributing hash power to the secretly mined chain, you would likely want to reevaluate your participation in that pool. Using Stratum V2, which adds more security and transparency, would be a logical step to ensure that your hash power is being used as you intend. Creating new, trusted pools or joining known trustworthy ones could be an appropriate reaction as well.

If 1000 blocks are too many, what if it was 5?: If the reorganization was only 5 blocks, it would be within the realm of what's occasionally seen on the network (though still rare). In this case, a drastic change in behavior, such as waiting for hundreds of confirmations, might not be warranted. However, it might still prompt a review of the network, mining pools, and other factors to ensure that everything is operating as expected.

Going to a #Bitcoin Meetup tonight..will have a beverage. If you want to kick in some sats can zap this post

Can you summarise this for people that are borderline retarded?

Asking for a friend.

ZAP CONTEST! ⚡️

First one to answer the name of this classic video game, will receive 1,000 cool sats! 😎

Sort of unrelated, but do you happen to know why Liquid peg ins take 102 confirmations? Are they trying to get the probability of a reorg to ~0%?
