Launched on 12/12/2019 by a team based in Singapore. KDAG aims to solve the problem of efficiency.  KDAG architecture completely replaces the traditional chain structure. The "embracing algorithm" instead of consensus completely solves the data consistency, and the "wave effect" greatly improves the random attribute of the node's legal reference, and realizes the high security of transaction privacy.

Solve.Care is a healthcare platform company that uses blockchain to redefine care coordination, improve access to care, reduce benefit administration costs, and help reduce fraud and waste in healthcare around the world.

The Solve.Care platform (Care.Platform) allows for digital health networks, called Care.Networks, to be built and run for patient-centric care that can be based on medical conditions, economic and social needs, creating an entire healthcare ecosystem. Using Care.Platform, clients can launch networked, interoperable healthcare dApps, within a very short time frame.

Care.Networks on Care.Platform use the SOLVE token, a utility token that is used for inter/intra network payments and transaction fees. It also has additional uses including developer rights, staking, marketplace payments, and platform access fees.

Peercoin, also known as PPC or Peer-to-Peer Coin, was created by Sunny King and his team and launched in August 2012. It is the first blockchain to implement Proof-of-Stake consensus.

The primary inspiration behind the creation of Peercoin was to address a number of perceived shortcomings of Bitcoin, including energy efficiency, security and sustainability, decentralization and long-term viability.

Essentially it was designed as an enhanced replacement for Bitcoin. As such, it was originally forked from Bitcoin and uses the same UTXO style blockchain. However, Peercoin's code was modified to introduce Proof-of-Stake as its primary consensus protocol. The next section explains how this makes for a better blockchain.

Given that Peercoin uses most of the same code, it can easily port new features from Bitcoin and utilize any of the supporting infrastructure, including tech advancements like Taproot or Lightning Network. Peercoin is the only Proof-of-Stake blockchain that uses modern Bitcoin code, making it the perfect drop-in replacement.

Peercoin also has a dedicated community, is actively developed, fairly distributed, has low barriers of participation, can do everything that Bitcoin does, minus the 13 TWh of energy usage, and it's not a scam.

ABBC is a blockchain platform that enables secure payment transactions, helping to facilitate retail adoption of cryptocurrencies and make shopping online with digital assets a safer, more enjoyable experience for end-users.

The platform offers three main products: a multi-platform wallet capable of supporting Bitcoin (BTC) and Ethereum (ETH), in addition to a variety of other native cryptocurrencies and ERC-20 tokens; an online shopping application that can be used to shop at over 50 online retailers with cryptocurrencies; and a cryptocurrency exchange platform that offers secure trading and low transaction fees.

The ABBC Coin was created to give holders the ability to govern the development of the ABBC platform by delegating voting power to chosen block producers (BPs) — who are then able to vote on governance proposals. These governance proposals can be on a range of topics but might include launching strategic partnerships, implementing new features or expanding ABBC's services to new regions. Beyond this, ABBC Coins were created as a reward system for online shoppers and can be staked for regular rewards.

ABBC is currently based on the EOSIO blockchain, which enables it to achieve up to 5,000 transactions per second (TPS) while remaining environmentally friendly due to its energy-efficient delegated proof-of-stake (DPoS) consensus mechanism.

ABBC Coin was initially known as Alibabacoin but changed its name in March 2019 following a dispute with Chinese multinational e-commerce giant Alibaba.
