The Amp token is a digital collateral token that is specifically designed to enable the decentralized collateralization of digital asset transactions. It evolved from what was previously known as the Flexacoin network, and is meant to allow the token to better facilitate recent innovations related to borrowing and lending in the DeFi space. The Amp token's supply was created by burning the existing supply of Flexacoins, which were exchanged for the new token at a rate of 1:1. Amp will improve upon Flexacoin’s collateralization features with a new architecture that will allow for the implementation of additional on-chain supply operations and more collateral-related DeFi options.

Denarius is a hybrid cryptocurrency with a consensus mechanism that combines elements of Proof of Work and Proof of Stake. Denarius' cryptographic hashing algorithm, Tribus, is ASIC resistant, and consists of three of the most secure and popular cryptographic algorithms. Denarius is named after a Roman coin that was widely used during the peak of the Roman Empire.

ZCoin is a privacy focused cryptocurrency built on Ethereum. The ZCoin protocol enables anonymous transactions with cryptography that utilizes Zero-Knowledge Proofs (ZKP). ZCoin increases privacy on their network by using a coin-mixer contract that wraps transactions in a serial number and destroying wrapped coins once they have been redeemed.
Zcoin was the first cryptocurrency to use a Merkle Tree Proof (MTP) as its proof of work algorithm. Merkle Tree Proofs are an innovative solution to achieving network consensus, and can increase transaction time while reducing the centralizing tendency of ASIC mining.
