Fiat-Shamir Identification: Non-Interactive Zero-Knowledge Proofs

See full implementation code on GitHub

The ability to prove knowledge of some secret information without revealing the secret itself is crucial. Fiat-Shamir Identification demonstrates how this can be achieved in a way that doesn't require interaction between the prover and verifier. Further, Fiat and …

Emacs global-set-key

This video demonstrates how to set a custom global keybinding in Emacs to open the org agenda folder.

(setq org-agenda-folder (quote "~/org"))
(defun open-agenda-folder () (interactive) (dired org-agenda-folder))
(global-set-key "\C-cr" (quote open-agenda-folder))

mocking calls to specific addresses in solidity

Mocking a specific address signature in Solidity is useful for simulating expected behavior from an existing address or instance of a contract. In mock testing dependencies are replaced with simulated implementations to isolate the behavior of the funtion under test.

Proxy contracts that …

Here is a simple gist that demonstrates how to generate a random hex string in Python. This is pseudo-random and designed only to be used for generating test data.

Even for non-emacs users it can be powerful to understand the basic emacs command editing paradigm. Both Mac OS and the Unix and Linux shell allow emacs style command editing in text contexts. This basic introduction goes over the basics of emacs "chords" and control of the command line. An …
