Every release ships the binaries and a SHA256SUMS file covering them. Verifying takes a second and is worth doing — it is the only thing standing between you and a file somebody else swapped out.

Verify what you downloaded
Put the release files and SHA256SUMS in one directory:
sha256sum -c SHA256SUMSOn Windows, without a shell:
certutil -hashfile Bitflash-1.2.15-windows.zip SHA256When a signature is published, check who signed the checksum file before trusting the checksums:
gpg --verify SHA256SUMS.asc SHA256SUMS
sha256sum -c SHA256SUMSThe repository carries a helper that fetches a release, verifies the signature when present, and then checks the hashes:
scripts/verify-release.sh latestThe full audit procedure is in release verification.
Keep your node current
Consensus rules have changed since the first releases. 1.2.1 fixed a bug that let anyone spend anyone's coins, and 1.2.2 added a per-block signature-operation cap. A node on an older build will accept blocks that current nodes reject, which puts it on a different chain with no warning at all.
Your wallet and chain data live in %APPDATA%\Bitflash on Windows or ~/.bitflash on Linux and are shared by every version, so upgrading is just replacing the binary. Never delete that directory to "fix" something without a backup — it holds your keys.
