Gulden is a Dutch cryptocurrency based on a native blockchain with a Proof-of-Work (PoW) consensus mechanism. Gulden has gained traction in the Netherlands, where it can be used to make P2P payments, as well as send funds to an IBAN account. Gulden's marketing efforts emphasize the network's security and faster transaction times. Gulden's PoW² consensus combines aspects of PoS with PoW, and allows witnesses to add transactions to blocks after they have been mined. The network is powered by the NLG coin.
