Developer mines Bitcoin on Apple II, achieving 3.8 hashes per second

by@DocumentingBTC

Summary

A developer successfully mined bitcoin using an Apple II, a home computer from 1983, with the help of programmer Peter Ferrie, who optimized the code to achieve about 3.8 hashes per second. Given bitcoin’s hashing algorithm reliance on thirty-two-bit operations, the program had to creatively construct these from smaller components. The mining operation was aided by a modern Mac that relayed tasks to the Apple II via a virtual floppy disk. Despite this achievement, the developer estimated that at the prevailing difficulty level, it would take approximately 256 trillion years to find a block, highlighting the incredibly challenging nature of bitcoin mining, especially as it is noted that Bitcoin's mining difficulty has recently lacked significant increases amid changing market trends.

Analysis

Bitcoin: Bitcoin is the original decentralized cryptocurrency that secures its network through proof-of-work mining based on the SHA-256 hashing algorithm. The news illustrates the fundamental mismatch between Bitcoin's 32-bit operations and the limitations of 1983-era 8-bit hardware. Peter Ferrie contributed key optimizations to make a functional miner possible on the Apple II despite these constraints. Peter Ferrie: Peter Ferrie is a programmer renowned for expert-level optimization of assembly code on vintage computing platforms. In this news, he provided critical refinements to the Bitcoin mining routine for the Apple II, dramatically improving its efficiency through targeted cycle reductions and routine streamlining. Network Trends: Bitcoin's mining difficulty has undergone one of its longest stretches without reaching a new all-time high amid evolving market conditions. Mining Economics: Recent reports indicate Bitcoin mining electricity consumption may have peaked due to halving dynamics and rising opportunity costs from competing uses of infrastructure.
