PirateChain (ARRR) is a 100% private send cryptocurrency. It uses a privacy protocol that cannot be compromised by other users activity on the network. Most privacy coins are riddled with holes created by optional privacy. PirateChain uses ZK-Snarks to shield 100% of the peer to peer transactions on the blockchain making for highly anonymous and private transactions.
The developers who created zcash, which PirateChain is based on, believe the best use of the protocol is a chain that requires private sends only. Komodos delayed Proof of Work (dPoW) protects Pirates blockchain from damage against double spends and 51% attacks by attaching a backup of the ARRR chain to the Bitcoin Blockchain. In order to 51% attack Pirate, you would have to first 51% attack Bitcoin. This makes security against double spends and hostile takeovers nearly impossible if not impossible altogether.
