Thanks @freetrader! I link the video on the right moment for other interested in the Pieter's "err..." moment
Any reference links to this (please )?Correct. If you sign a message with your ECC private key, then the ECC public key can be derived from the message and signature. It is a public key after all
I just made this as a demonstration using vitalik's excellent pybitcointools library..priv=random_key()
>>> pub=privtopub(priv)
>>> priv
'f326193cb51b47d54b60d867e4742289d04357f4f92b6403443c407dc2b206a4'
>>> pub
'042b8bbe8aefdbd4ec571f5405c189541a1377f256c8847e09ebabf7e8cb67cc677bc114a9db11159094e2d257ac83fe2116f39742a2ff43011c76c67888f6f948'
>>> sig=ecdsa_sign('this is a message',priv)
>>> sig
'HGFusoKdZ7uU/GPP3PiIk/hrD+WNy0K6KDveYoo2A1yOdTJK+u3MWZCnxZr0UeZUeV3c7Zt5ct679ujlO7pGdss='
>>> derived_pub=ecdsa_recover('this is a message',sig)
>>> derived_pub

Pieter is a very intelligent guy, extremely rational and knowledgable. (I talked to him briefly in the early days at the Prague conference). That's why when I saw that video end of last year it became suddenly clear to me that he wasn't standing behind what he was saying. It was kind-of an aha moment for me. He must've either gotten talked into it (peer-pressured or whatever) or manipulated or coerced some other way.@tynwald
Pieters reaction to the question made me lose tons of respect for him.
my guess is that he's totally sold all his coins and the POW fork he was advocating is stalling out. too bad, i miss him too.Does anybody here know what's up with @rocks or had any contact to him?
Haven't heard from him and his big blocks fork for a while and he didn't answer questions.
