Craig Wright denies forging documents to support bitcoin claim

Australian attacks qualifications of his own expert witness during testimony at high court in London

Craig Wright, the Australian computer scientist who says he invented bitcoin under the pseudonym Satoshi Nakamoto, has denied forging documents to support his claim.

In his first day of giving evidence at the high court in London on Tuesday, Wright flatly denied any forgery or falsification and attacked the qualifications of his own expert witness who found otherwise. The hearing was part of a lawsuit brought by Copa, a coalition of cryptocurrency-linked tech firms that seek to invalidate his claims.
