Responsible bitcoiners Verify. They don't simply trust. Keeping this in mind I was reviewing BIP-340. One of the major justification for this BIP is signature malleability fix. In this video I explain with step by step mathematical reasoning to why ecdsa has 2 valid signatures, while it's impossible to do such with schnorr.

Left vs Right is a distraction. Capitalism vs Socialism is a distraction. Women vs Men is a distraction. .... It has always been the ruling class distracting the plebs with propaganda. The bankers are the ruling class of this Era. Don't fall for their propaganda. Stay focused on #bitcoin. Winners write history. Our civilisation is built on top of the corpses of the good guys. Let the good spirits lead us to salvation.

The fiat machine convinced the boomer generation (even in India) that being a salaried employee is the safest way to live a life. During the boomer generation jobs were plentiful and they contributed to the technologies of convenience thar are abundant today. They also empowered the Fait machine to a great extent. The millennials followed the dream of Boomers and bet their whole life on the college degrees and this is exactly the trap laid by the machine, now they got generational debts slaves for a mere exchange of "certificates". Atleast the boomers were able to own houses and farms! Binge watched the YT videos by Freddy Smith,and upon further contemplation it's clear that the machine has created a divide between generations. Even people of same bloodline are up against one another due to the programming of the machine. Now Genz have two options. 1. Solve the problems as an entrepreneur, or 2. Wage slavery. The interesting thing is, the parents of boomer or millennial generation can help Gen Z with their capital. But I have a strange feeling that it won't happen in a large scale because the machine has programmed to masses to hate each other and very few break out of the programming!

Amazing thing about bitcoin that we take for granted is that it allows Alice to send sats to Bob while Bob is offline. We need L2/L3 protocols on top of bitcoin to avoid high fee rates. Cashu ecash is what I would consider an L3 protocols which allows Alice to send ecash with Bob, which a trusted mint acts as a bank. But this requires Bob to be online! Tradeoffs!! NOTE: Whoever the first to redeem the ecash token from the mint gets paid! So it has to be kept as secret between Alice and Bob, just like paper cash. In internet we would like things to work asynchronously. That is even when Bob is offline, he must be able to receive ecash from Alice. Cashu NUT-11 addresses this problem by facilitating the creation of ecash tokens which are locked to a public key, very similar to how bitcoin UTXOs are locked in Transaction output. NIP-61 defines the format in which these payments can be stored in a nostr-relay. Bob has to publish his cashu pubkey, mints he trust etc., as a nutzap info event and Alice can publish the ecash tokens which are locked into Bob's public key as nutzapp payment event. I have written a code example in rust using nostr_sdk and cdk

Hi I’m working on creating a course Rust for Bitcoiners with the help of Chaincode. Will keep you posted. Let me know the feedback in the comments

Spender provides the condition for the bitcoin conditionals. #just_taking_notes
