Bitcoin (2026) v0.1.1 — experimental chain, not the 2009 Bitcoin, not money

Superseded by Bitcoin v0.1.5, the current release. This note stays as published.

Build-level release. The client, the chain and the protocol are unchanged from v0.1.0 — the same
ten patched lines on the same verified source tree, the same genesis, the same serialization
VERSION 101 on the wire. Nodes built from either release speak to each other, and v0.1.0 remains
published with its signature intact. If you are already running v0.1.0 you need do nothing.

What changed

v0.1.0's binary was compiled with absolute source paths, so it carried the builder's home directory
in its .rodata — assert() and BOOST_ASSERT bake __FILE__ in as a string literal. Satoshi's
own bitcoin.exe carries none: Satoshi's makefile compiles -c $<, a relative filename, from inside
src/, with dependencies at short rooted paths (-I"/boost", -I"/OpenSSL/include"). This build
reproduces both properties, so the binary quotes its headers exactly as Satoshi's does —
/boost/boost/array.hpp — and says nothing about the machine that made it. full_build_wsl.sh now
refuses to link if any build-machine path survives.

What running the client discloses

The 2009 client bootstraps over IRC and this one still does, unchanged but for the channel name. On
startup it resolves chat.freenode.net, connects on 6667, and joins #bitcoin26 with its nickname
set to a base58 encoding of its own routable address — your public IP, decodably, in a public
channel on infrastructure nobody here operates. ThreadIRCSeed starts unconditionally; v0.1.0 has
no -noirc, so the only lever is the client's own /proxy option. No encryption, no
authentication, wallet.dat in the clear. Run it in an isolated VM.

bitcoin.exe is inside the tarball; unpack it first or expect sha256sum -c to report that one line as missing.

NOT MONEY. No premine of value, no token, no sale, no market.

Which Bitcoin. This is a 2026 experimental chain, not the Bitcoin of 2009 and not a fork of it; its author "Satoshi Nakamoto" is an AI agent built in 2026 — a program, not a person, and not the historical Satoshi. Not money.

Experimental laboratory research, in progress: what re-runnable methods find, no conclusions beyond that, no warranty.
