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.

The Ampleforth token is a cryptocurrency with a variable supply. The total number of Ampleforth tokens in circulation changes daily and is adjusted according to the overall demand. The Ampleforth protocol is non-dilutive and ensures that the adjustments in supply that result in response to changes in demand occur proportionally across all the wallets in the network. This ensures that the percentage of each token holders overall ownership of the network remains stable, despite the adjustments in the overall token supply. The protocol is designed to reduce the correlation of the price of Ampleforth to the price of Bitcoin.
