Aeternity (AE) is a blockchain platform that focuses on high bandwidth transacting, purely-functional smart contracts, and decentralized oracles. It was founded in 2017, and seeks to eliminate inefficiencies in the crypto market by increasing scalability of smart contracts and dApps, sharding, and off-chain contract execution. The Turing-complete smart contracts on the Aeternity chain allow for transaction execution without third parties or intermediaries. Aeternity also has state channels to enable off-chain smart contract settlements which only touch the blockchain should a disagreement in the contract arise, acting as a self-arbitrating crypto court. The Aeternity blockchain is also built upon state-of-the-art cryptographic data structures which give rise to robust efficiency, strong security, and the elimination “single point of failure” (SPOF) issues.

Firo (FIRO), formerly known as Zcoin, is a cryptocurrency that focuses on being private digital cash. It created the Lelantus privacy protocol which allows users to burn their coins and redeem them later for brand new ones that do not have any transaction history.

Prior to Lelantus, it was also the first cryptocurrency to code and launch a practical implementation of the Zerocoin protocol which became one of the most prevalent privacy protocols in use, prior to it being replaced by Sigma and then Lelantus after cryptographic flaws were discovered in the Zerocoin protocol in 2019.

BitShares Blockchain is a decentralized “Blockchain as Organization” (BaO); an industrial-grade decentralized open source platform built to run high-performance financial technology operations. It represents the first decentralized autonomous decentralized community that enables its core utility token (BTS) holders to decide the Blockchain future direction in order to develop and maintain a wide range of decentralized financial technology products, features and functions. BitShares Blockchain is a Blockchain that permanently records financial technology operations between different Blockchain accounts and facilitates a wide range of access controls across BitShares Blockchain user financial means.

BitShares Blockchain is a technology that supports the digital generation entrepreneurs, investors, and developers with a common interest in building and participating in free market solutions by leveraging the power of globally decentralized consensus and decision making. Consensus technology has the power to do for economics what the internet did for information. It can harness the combined power of all humanity to coordinate the discovery and aggregation of real-time knowledge, previously unobtainable. This knowledge can be used to more effectively coordinate the allocation of resources toward their most productive and valuable use.

BitShares looks to extend the innovation of the Blockchain to all industries that rely upon the internet to provide their services. Whether its banking, stock exchanges, lotteries, voting, music, auctions or many others, a digital public ledger allows for the creation of distributed autonomous companies (or BaO) that provide better quality services at a fraction of the cost incurred by their more traditional, centralized counterparts. The advent of (BaO) ushers in a new paradigm in organizational structure in which companies can run without any human management and under the control of an incorruptible set of business rules. These rules are encoded in publicly auditable open source software distributed across the computers of the companies’ shareholders, who effortlessly secure the company from arbitrary control. BitShares does for business what bitcoin did for money by utilizing distributed consensus technology to create companies that are inherently global, transparent, trustworthy, efficient and most importantly profitable.

BitShares has went through many changes and has done its best to stay on top of Blockchain technology. BitShares is using Consensus as the mechanism by which organized people decide upon unitary rational action. While not considered technology in the traditional since, consensus “technology” is the basis of democratic governance and the coordination of free market activity first coined by Adam Smith as the “Invisible Hand.” The process of consensus decision-making allows for all participants to consent upon a resolution of action even if not the favored course of action for each individual participant. Bitcoin was the first system to integrate a fully decentralized consensus method with the modern technology of the internet and peer-to-peer networks in order to more efficiently facilitate the transfer of value through electronic communication. The proof-of-work structure that secures and maintains the Bitcoin network is one manner of organizing individuals who do not necessarily trust one another to act in the best interest of all participants of the network. The BitShares ecosystem employs Delegated Proof of Stake in order to find efficient solutions to distributed consensus decision making.

Aergo describes itself as an open-source enterprise blockchain platform optimized for hybrid deployments, which consist of both permissioned and permissionless blockchain architectures. It includes support for SQL allowing for easy data handling and familiar smart contract programming for developers.

The platform is built and utilized by Blocko, the Samsung-backed South Korean blockchain technology company that, according to Korean media sources, has deployed production blockchain solutions for large-scale clients including Lotte Card, Shinhan Bank, Korea Exchange, Hyundai Motors, and more.

Kleros (PNK) is a decentralized dispute resolution project that launched in July 2018. It is an open-source online dispute resolution protocol that uses blockchain and crowdsourcing to adjudicate disputes fairly.

Kleros offers a middleman service for decentralized applications (DApps) and their users. If the service provided by the application does not create a dispute, Kleros acts as a trustless third-party service for payment.

When a dispute does occur, however, each party can apply for arbitration through the Kleros arbitrators that are selected from the owners of PNK tokens. PNK is an Ethereum-based ERC-20 utility token with a fixed supply.

At this point, the jurors can make a decision that will favor either party. The arbitration fees are distributed to all arbitrators in the form of ETH; jurors who have issued a minority decision lose part of their PNK tokens for the benefit of the majority of jurors. This decision can be appealed, at a cost. The stated mission of Kleros is to offer easier access to justice and improve individual freedom.

Kleros charges a cost that is payable in ETH and is provided by the parties to the dispute or drawn from the funds previously locked in escrow.
