Workshop #1 - Intro & Bitcoin .pdf

Summary

In collaboration with WAB, W3B presents the first event in the Blockchain Technology seminar series: Blockchain & Bitcoin 101.

Notes

1. Bitcoin mining difficulty: The current mining difficulty https://btc.com/stats/diff is actually set at 37.59, which is apparently 21 leading zeros. The “leading zero” idea is a bit coarse and not 100% accurate. Please refer to this website to learn more https://en.bitcoinwiki.org/wiki/Difficulty_in_Mining
2. Public private key explanation: https://www.youtube.com/watch?v=AQDCe585Lnc
3. Specifically, the leading symmetric encryption scheme(which bitcoin uses) is ECC, explained here https://blog.cloudflare.com/a-relatively-easy-to-understand-primer-on-elliptic-curve-cryptography/
