Helps with perspective. +Naturally, stay away from mainnets and real money if you do your own +wallet and crypto. + +-Don't get too excited when you'd see exploitable signatures. +All of them were plundered years ago, and by now no one makes mistakes +like that. +Also, there are plenty of bots which are constantly scanning the chain +for weak keys and signatures, any new ones will be gone in a few +seconds. + +-Expect cthulhus. There used to be plenty of artwork and puzzles in +the early blockchain. +Here is a short write up with a few of the things i found: https www +dot ribbonfarm dot +com/2017/07/20/the-ominouslier-roar-of-the-bitcoin-wave/ + + +For references, good ones i found and used were: +https bitcoin dot org/en/developer-reference +https en dot bitcoin dot it/wiki/Protocol_documentation +Also, BIPs contain a lot of specific details: https github dot com/bitcoin/= +bips +That should get you started, and by the time you get into the devilish +details you'll have to look at the code for reference. + +No idea about 3), haven't looked at it. + +Good luck and have fun. +-Artem + +=D1=81=D1=80, 7 =D0=BD=D0=BE=D1=8F=D0=B1. 2018 =D0=B3. =D0=B2 15:01, <bitco= +in-dev-request@lists.linuxfoundation.org>: +> +> Date: Tue, 6 Nov 2018 23:21:11 +0200 +> From: rze <rzeqeu@gmail.com> +> To: bitcoin-dev@lists.linuxfoundation.org +> Subject: [bitcoin-dev] Considering starting a toy full-node implementatio= +n.
