About Bitcoin Library
Last updated: September 3, 2026
Bitcoin Library (bitcoin.ne.jp) is a free educational library centered on Bitcoin and the history of computing and distributed computing behind it. That history runs from EDVAC, transistors, the PS3 Cell, CPUs, GPUs, FPGAs and ASICs through supercomputing, the GPU and memory systems behind AI, quantum computing, futures of computing and intelligence, BOINC, PrimeGrid and NTT DATA Gene, alongside compute incentives and blockchain. It covers 45 bilingual topics across 8 fields, supported by 42 verifiable diagrams.
Focused guide to distributed prime searches: PrimeGrid and the cryptographic boundary
Purpose
This site presents Bitcoin not as an isolated invention but as knowledge connected to computing and semiconductor history, distributed-systems research, volunteer computing, the accounting and incentives of compute, distributed consensus, and blockchain design. Everything is free to read, with no advertising and no registration. Analytics are limited to consent-based Google Analytics 4, controlled by the cookie banner and disabled by default, and nothing is tracked for advertising. See the privacy policy for details.
What this site does not provide
- -Trading, exchange, brokerage, or intermediation of crypto-assets

- -Legal, tax, or financial advice
- -Exchange referrals, affiliate links, or advertising
- -Collection of personal information such as names or contact details
Target audience
This site is for readers who want a systematic understanding of Bitcoin mechanics, history, economics and institutions, together with the distributed-computing systems, the allocation and incentives of compute, and the blockchain designs beneath them. Beginners and advanced readers are both welcome. It is not for anyone seeking price predictions or quick profit: it is for readers asking where Bitcoin sits in technical history and under which trust assumptions it works.

This site is operated by KK siiiiiixth as one of its own educational products. For enquiries about the site, including reports of errors in an article, use the "Contact" page linked at the bottom of every page.
Editorial policy
The editorial principles we follow (primary sources first, neutrality, fact-checking, no price predictions, no advertising, and a stated update cadence) are published on the editorial policy page. Every article lists its primary sources, the References page curates starting points, and the Sources & Research Index exposes the complete citation graph. Diagrams favour code-native forms that can be checked against the text.
Update policy
Topics with time-sensitive content (regulation, tax, ETFs, economic data) show an explicit last-updated date and links to primary sources. Historically and technically stable topics are updated only when a factual correction is needed.
