Some new fimulation Im working on.

What are niches that are specific only to the Bitcoin industry? One example: ASICs.

I really miss street photography.

In what step/process does Bitcoin prevent double-spending? Pls answer without searching anywhere or consulting the code.

Dude when I saw this cartoon as a kid on TV, my mind was absolutely blown.

Am I really the only person that just finds all these AI chat things not usefull like at all?

When making a signature you need entropy for each signature(true for Schnorr & ECDSA). Why? Well that's how you hide your private key, you mix your private key with this random number(slightly more complicated) So every time you sign a TX you need a fresh new nonce(entropy) for the signature. The thing is that even if you have 1 single bit of bias in your entropy an attacker can guess your private key. (Yes this happened IRL quite a bit 2013, there are ofc some caveats which I'll hand wave :p) So a new standard was made where you create deterministic entropy(statistically evenly distributed) to be used for signatures. More info on the standard:

IETF Datatracker

RFC 6979: Deterministic Usage of the Digital Signature Algorithm (DSA) and Elliptic Curve Digital Signature Algorithm (ECDSA)

This document defines a deterministic digital signature generation procedure. Such signatures are compatible with standard Digital Signature Algori...

The "funny" part about entropy is that you can't tell if something is actually random. An actually random number can legitimately have well any digits there. There is absolutely no way to tell if something is truly random or not. So the only option to be safe is to make sure the devices you use do what they were mean to do. How do you know that your hww is actually using this standard and not rogue entropy? Well, one solution is to contribute to this entropy using your device that communicates with the hww (like your laptop) This is called "anti-klepto" and is currently only implemented by @BitBoxSwiss and @BlockstreamJade . In the below example, the attacker modified the firmware of the SeedSigner so that it contributes bad entropy to the signature for the TX in question, and this will not raise any suspicion to the user. The reason this was successful is BECAUSE they used a malicious firmware, so if you check the "correct" firmware is loaded on youfirmwarer device you should be ok. But what if there was an error made by the people who implement the wallet firmare? Well, that's why something like the anti-klepto helps.

Have you ever used a Bitcoin HWW directly with Bitcoin Core? If so how did you interact with it?

Dude, primal is something else. By far the best experience on nostr for me so far!

Did you know the pre-released 2008 version of #Bitcoin had 15-minute block time? Also, the difficulty adjusted every 30 days. Satoshi changed to 10-minute block times & 14 days difficulty adjustment in the version he released on 9 Jan 2009 and that's used today.

Did you know 1 #Bitcoin initially was NOT 100,000,000 sats? Before releasing the Bitcoin Client on 9 January 2009, Satoshi shared with some people an earlier 2008 version. In this version, among other things 1 Bitcoin = 1,000,000 (ofc he did not call them Satoshis :p)

0.03223686 ~ $1,300 UP FOR GRABS! In this address bc1q7l0h956r8sqfzjw3278s35p43z0zzmqnfnmfr4 , there is 0.03223686 ~ $1,300 and they are up for grabs. Why? Well because this is a game organized by Wasabi Wallet called #HuntingSats, the scope is to challenge people to learn how to use Bitcoin wallets and be rewarded for their work. More info: https://www.huntingsats.com/anniversary Each of the companies in the picture was given 1 of the 12-word BIP39 seed phrase that unlocks the wallet. They will release the word on their Twitter(I know it sucks and all, but hey do you want the sats or not?) at any time between (today)23 January and 26 January You should follow them and the #HuntingSats hashtag to get the word before anyone else.

Each of the companies will release their word whenever they want and no coordination was done between the companies, which means YOU have to figure out the correct order of the 12 words. There are 479,001,600ish ways in wich you can order the 12 words, and only 1 unlocks the Bitcoins. Satoshis Don't Exist(the movie I'm directing) is one of the partners and this is the word we were given. I'd wish you good luck, but luck has absolutely nothing to do with it! (and yes, I did take all the pictures :p)
