# Legacy Network Compatibility

> **Verified against:** the latest stable release; exact review revisions are recorded in [Pinned source and release revisions](/contribution-and-evidence/source-version-matrix.md).

The current Qwertycoin network is not a continuation of the historical chain.

Do not reuse:

* old blockchain databases or daemon data directories;
* old peer-state files or checkpoints;
* old wallet cache files as if they represented current transactions;
* `simplewallet`, `walletd`, old container-wallet APIs, or port 8070 guides;
* CryptoNight/XMR-Stak mining configuration;
* legacy masternode registration transactions or `--service-node*` flags.

Current binaries are `qwertycoind`, `qwertycoin-wallet-cli`, and `qwertycoin-wallet-rpc`. Current proof of work is RandomX. Current EPoSE enrollment is automatic and identity/epoch-bound.

Old mnemonic/key material may be imported only as a key-recovery experiment. A successful import does not transfer or recreate balances from the legacy chain. Use a new current-network wallet for normal operation and verify addresses with current software.
