Namecoin is a blockchain-based DNS that allows users to register domain names with a ".bit" domain. Namecoin was the first fork of the Bitcoin protocol and it aims to remove centralized control over domain registration. It was the first cryptocurrency to use Auxiliary Proof of Work (AuxPoW) as a consensus mechanism,
where a child blockchain is dependent on the Proof-of-Work consensus of the parent blockchain. This allows for Namecoin and Bitcoin to be mined simultaneously, and when a new block is created on Bitcoin, it will also be added to the Namecoin blockchain.
Namecoin is a very important project that represents one of the best use cases of blockchain technology in protecting free speech and resisting censorship on the internet. It is powered by the NMC coin. The decentralized DNS provides more security from hackers and government intervention.

Tendermint is a consensus algorithm that was created by a company called All in Bits. The open source algorithm is Byzantine Fault-Tolerant and uses an authenticated encryption system to secure transactions. The Tendermint consensus mechanism was developed in 2014 for the Cosmos Network. The Interchain Foundation, which is developing the Cosmos Network, continues to employ All in Bits to support Cosmos.

EdenChain is developing an enterprise tokenization platform that will be based on their permissioned blockchain technology. Their goal is to enable enterprises to create customized digital assets based on their unique needs, and still maintain a high degree of control and privacy. EdenChain will use Merkle Tree and Namespace technology to solve performance issues by executing transactions in parallel; thus enabling more transactions per second, with lower transaction fees. EdenChain utilizes both a hardware and software solution to arrive at a consensus, and has a triple layer architecture that is significantly different from other tokenization platforms. Their hybrid consensus mechanism that will combine a protocol called Median Voter Thereom (MVT) with Proof-of-Elapsed-Time (PoET). PoET was designed and marketed by Intel, and is similar to PoW but requires less electricity. The company issued an Ethereum-based token called EDN.
