CloakCoin V2.2.1.0-beta 'REVOLUTION' For Linux & Windows


Dear CLOAK Community,

We're pleased to announce the CloakCoin v2.2.1.0-beta 'rEVOLUTION' wallet for Linux and Windows.

The Mac & Raspberry Pi wallet will be available soon.


Version 'rEVOLUTION' brings various fixes & improvements; biggest change is full wallet file encryption/decryption on exit/start, fixing a major anonymity flaw detected and explained in Cognosec's audit report (balance & transaction information access).

For improved and added security, users can now enter a password on every wallet shutdown (if they want), fully encrypting the wallet file information, including balance & transactions. Users will be prompted for a passphrase to decrypt their wallet on startup if needed, software will automatically detect whether it's a standard or an encrypted wallet. IMPORTANT: As always, please DON'T forget the passphrase entered - the coins/funds will be lost and wallet file rendered unusable!

The 'Encrypt wallet' functionality previously available in the wallet is still there - keep in mind it will only encrypt your private keys though, an evil actor with unrestricted access to your wallet.dat (such as a backup) might still view your balance and transactions data. 'Backup wallet' functionality was not modified and still creates standard/unencrypted backups - if you want to store an encrypted backup please exit the wallet, encrypt it with a passphrase when prompted and store a copy of current wallet.dat file.

Changes done:

  • fully encrypted wallet.dat on QT wallet exit: safer storage of your wallet.dat & restricted access to account/transaction info (backup wallet function still makes unencrypted backups)
  • DLLs required and the app install folder are now read-only & hidden; elevated privileges required for write access
  • optimized loading performance by doing smart things with big numbers calculations: 20% faster blockchain index loading time
  • increased dbcache defaults in src/db.cpp & src/txdb-leveldb.cpp, resulted in 30-50% speed performance increase for syncing blocks
  • removal of BigNum dependency in some code parts & trust calculation optimization (uint256) seems to have fixed the memory leak/bloat on both QT & daemon (yay Anorak!)
  • TX view in block explorer
  • Install over existing wallet
  • Enable Enigma by default
  • ABSOLUTELY CRUCIAL FIX FOR ENIGMA - cloaker addresses were not picked up when scanning in certain rare cases, which would result in lost funds instead of a reward for participating in Enigma. Great news: these can now be recovered by running 'scanforstealthtxns' in the (debug) console!

    Planned/in-progress TODOs:

  • dev fund & governance
  • voting system (solid idea in place, wfc)
  • reskin the UI to something more modern (designs exist)
  • phase out BigNum completely and other possible structs/types that prevent compiling with openssl 1.1.x
  • upgrade btc-dependent code to more recent btc/ltc codebase (not looking forward to that, long overdue)
