Emercoin is a blockchain-based development platform. It has developed a range of easy-to-use dSDKs (Decentralized Software Development Kits) that can be used to more easily build DApps. This set of software development tools allow the creation of blockchain-based software and services.
Emercoin's dSDKs have been implemented in several innovative DApps and provide developers with solutions for a variety of functionalities. Some of the dSDK's that Emercoin offers are specifically geared for decentralized DNS, SSH, SSL, and DPO solutions.
Emercoin has a hybrid consensus mechanism that combines elements of Proof-of-Stake (PoS) with a Proof-of-Work (PoW) algorithm that is merge-mined with Bitcoin. The network is powered by the EMC coin.

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.

Holo is a decentralized hosting provider that is built on top of Holochain. DApps can be set up and deployed with Holo hosting, as a decentralized alternative to Amazon Web Services, or other centralized hosting solutions.
Holochain is a protocol for creating decentralized Apps and is different from blockchain protocols in several ways. The main difference being that Holochain takes an agent-centric approach to their consensus mechanism, and has a different approach to validating value transfers.
The HOT token is used for paying for hosting services on Holo, and users can be paid for offering their computing resources.
