Bitcoin Transaction Malleability

The lies of Mt. Gox

#bitcoin #crypto

I had the opportunity of participating in Aviv Zohar’s Advanced Bitcoin Seminar at the Hebrew University.

My task was to review Christian Decker’s article Bitcoin Transaction Malleability and MtGox [1].

My talk covered low level bitcoin protocol details, some bitcoin security, transaction malleability and the MtGox incident.

Here are the slides, Nadja Kahan was kind enough to let me use some of her drawings again.

For posterity, the single most useful resource I found to study Bitcoin internals was Ken Shirrifs’s blog post and his Bitcoin protocol python implementation.
