Harmony is developing an open consensus blockchain platform. Harmony's sharding-based consensus mechanism is designed to scale as the number of nodes increases in the network. Harmony aims to tackle issues related to scalability by optimizing across multiple layers in a way that will enable parallel transaction processing with reduced latency. Harmony is currently powered by the ONE token, which is built on the Binance blockchain.

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.

Komodo is a blockchain building platform that is focused on developing anonymity and security focused solutions. Komodo's platform, which was originally a fork of ZCash, is powered by the KMD token, and enables users to send anonymous transactions. Komodo has a delayed Proof of Work consensus algorithm.
Komodo also operates Chainmakers and Chainzilla; which assist clients in creating their own blockchains, decentralized applications, and initial coin offerings. Komodo also provides services related to wallet integrations and blockchain security.
Komodo held the first ever decentralized ICO and pioneered the concept of a dICO. Their goal is to allow users to more easily build blockchain solutions and decentralized exchanges. They are developing a decentralized ICO (dICO) platform as well as a decentralized exchange platform called BarterDEX.
