Build5: an experimental Linux rebuild
The 2026 rebuild updates the daemon and Qt wallet for OpenSSL 3, Qt 5, Boost 1.74 and newer Crypto++. It addresses selected key-handling, amount-overflow, RPC and peer-message security bugs. It does not restore a working network or establish that the wallet is secure.
The binaries were built on an upgraded Mint/Ubuntu 22.04 amd64 system. They require Crypto++ 8.9, newer than stock Ubuntu 22.04's 8.6, plus the matching Qt, OpenSSL and Boost runtime libraries, including Boost Chrono 1.74. The tar archive is not a standalone or universal Linux build; the Debian package declares its required dependencies.
Both downloads include documentation, source snapshots and licenses. SHA-256 checksum files are attached to the release: Debian checksum · Tar checksum.
Old macOS/OS X, Windows and other platform build scripts will not work as-is. Only the Linux build has been updated.
Modernization and security rewrite co-authored with Codex 6.1 sol.
Before experimenting
- Use a new data directory or a disposable copy of an old wallet.
- Keep an offline backup of the original
wallet.dat. - Do not assume that old seed lists, pools or exchanges still work.
- Do not expose the wallet's RPC interface to untrusted networks.
The ancient Berkeley DB 4.8 used by the Ubuntu 16.04-era wallet is retained and linked statically to preserve old-wallet compatibility. Historical wallet round trips and chain replay remain untested.
A piece of cryptocurrency history
Slothcoin began in 2014 as a playful cryptocurrency inspired by early Bitcoin-family wallets and memecoins. It uses Keccak proof-of-work, custom P-256 Schnorr signatures and a nominal 150-second block interval.
Build4 was rebuilt for Ubuntu 16.04 in December 2019. Build5 is a 2026 research experiment after years of inactivity, not a return to active maintenance.
