A Primer On Slowable Encoders
There is a specific type of cryptographic transformation that arises in storage-oriented blockchains. The transformation is a “slowable” 1-1 mapping which does not involve any secrets and is tradeoff-resistant in the following sense: it should not be possible to partially compute the function, store a fraction of the function’s state and then resume and finish […]
A deeper dive into CVE-2021-39137 – a Golang security bug that Rust would have prevented
This blog post discusses two erroneous computation patterns in Golang. By erroneous computation we mean simply that given certain input, a computer program with certain state returns incorrect output or enters an incorrect state.
