There is also the possibility to form the entire block based on a single private key (0.2 BTC per block) or any single public key without private keys (0.05 BTC per block).
Demo (part of the block): ...
Why would one pay 50 BTC for a script that simply multiplies a scalar key by lambda endomorphism, and curve point field elements by beta endomorphism (for X) and subtracts Y from field prime / negates the key?
Sorry to ruin your secret.
Hi! Well, a full 50 BTC? That definitely wasn’t my offer )) I discovered Lambda myself without even realizing that it had already been discovered before me.
I didn’t quite understand how you use the lambda endomorphism to obtain the entire group without private keys...
How about this kind of block?
