Curecoin 2.0 will be the first cryptocurrency to implement quantum-computer-resistant cryptography (Merkle Signatures), and will feature a mini-blockchain which significantly improves scalability and will enable incredibly-lightweight wallets for smartphones. The estimated time to confirm a payment on the 2.0 release will be a few minutes.
Merkle Signatures, based on a Merkle Tree of Lamport Signatures (single-use signatures based on selectively revealing portions of a private key which correspond to the bits the signer wants to sign), allow for incredibly quick-to-verify signatures (on the order of 10s of hashes), and unlike ECDSA (used by Bitcoin) are resistant to attacks by quantum computers. Our custom implementation of Merkle Signatures has been publicly available and in testing for over two years, and relies on decades of academic research.
