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.
