Description

The digital signature scheme of bitcoin with SHA256+secp256k1 ECDSA will be broken before 28 December 2018 by cryptography researchers.
The attack should allow to forge digital signatures for at least a proportion of 1/1 million bitcoin users and steal money from them.
It should be done faster than 2^100 point additions total including the time to examine the data.

Decision Logic

The decision will be based on the best attack known in academic cryptography literature.
The result should be disclosed or publicly demonstrated before or on 28 Dec 2018.
It should confirmed by a majority of at least 3 other independent researchers with a PhD in cryptography.
Attacks in which the message was not signed correctly e.g. repeated identical randoms are NOT valid attacks.
