æternity blockchain is an Erlang-based scalable smart contract platform engineered by programming pioneers to address some of the most fundamental challenges native to earlier blockchains. By redesigning blockchain technology at the protocol level, the æternity developer community has enabled the core protocol to understand and integrate a rich set of functionalities out of the box. 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.
Loopring is a non-custodial order book-based exchange protocol built using zero-knowledge (zk) technology. Released in November 2019, Loopring V3 introduced a zkRollup DEX design utilizing off-chain relayers to allow high-throughput trading with low settlement costs secured by Ethereum. Loopring users deposit their assets on-chain into a zkRollup smart contract and trade off-chain via relayers. Users’ funds are never transferred; instead users submit trades and relayers store the data representing users’ accounts, balances, and trade history off-chain then commit changes on-chain by submitting a valid zk proof to the ZkRollup contract. Users are always able to withdraw their assets with the data available on-chain. Loopring Exchange, a zkRollup DEX built using v3, went live on the Ethereum mainnet in December 2019. Loopring Exchange charges 0% maker order fees and taker order fees between 0.3%-0.10% depending on the trading pair. DEXes pay fees to Loopring Protocol; however, LRC is not associated with protocol fees. Loopring Protocol’s native LRC token is an ERC-20 designed to ensure the economic security of exchanges and align stakeholder incentives. Loopring’s latest audit was conducted by SECBIT in November 2019.
In today’s crowded and undifferentiated digital asset ecosystem, Aion introduces a distinct category of Open Applications. The OAN runs on Aion. As the native digital asset of The Open Application Network, Aion is used to secure and access the network. The OAN is a public infrastructure that creates a new design space for Open Applications. As a public system, a global community of individuals, software companies, and institutions secure and maintain the operations of the network. The critical functions are enabled and incentivized through Aion. The usage of the network is metered and paid in Aion, compensating those contributing to its operations. The OAN is solving the unintended consequences of today’s platform economies. As its economic underpinning, Aion is positioned as a leading digital asset backed by real usage today.
Decentraland is a decentralized virtual reality platform powered by the Ethereum blockchain. Within the Decentraland platform, users can create, experience, and monetize their content and applications. The finite, traversable, 3D virtual space within Decentraland is called LAND, a non-fungible digital asset maintained in an Ethereum smart contract. Land is divided into parcels that are identified by cartesian coordinates (x,y). These parcels are permanently owned by members of the community and are purchased using MANA, Decentraland’s cryptocurrency token. This gives users full control over the environments and applications that they create, which can range from anything like static 3D scenes to more interactive applications or games. Some parcels are further organized into themed communities, or Districts. By organizing parcels into Districts, the community can create shared spaces with common interests and uses. You can find a list of the original District Proposals on GitHub. The content that makes up Decentraland is stored and distributed via a decentralized network while ownership and transactions are validated on the Ethereum blockchain. MANA is Decentraland’s fungible, ERC20 cryptocurrency token. MANA is burned, or spent, in exchange for LAND parcels. For a current summary of critical stats like total and circulating supply, please visit our MANA Token Information transparency dashboard. See the Glossary for more information.

Power Ledger (POWR), based in Australia, encourages us to imagine a world in which electricity is dependable, affordable and clean for everyone. Powered by contracts on the Ethereum network, the peer-to-peer energy exchange platform, their most mature platform, aims to democratize the trading of energy with transparent systems that allow individuals and communities to select the source of their power. In their dual token model, POWR is the utility token that users would escrow in order to use the platform, whilst Sparkz represent electricity credits tied to local fiat for marketplace participants. Both are used to create part of an economy in which households that generate electricity can trade with their neighbors for a fair return. The Power Ledger Token (POWRTM) is the fuel of the Power Ledger Ecosystem with bespoke private trading applications creating Sparkz in exchange for POWRs. Sparkz are currently purchased and redeemed using fiat currencies with individual trading platforms hosting closed loop exchanges for energy and Sparkz. Energy trading applications are not just conceptual, they are proven and deployed in communities and energy markets around the world including Australia, New Zealand, Europe and Asia.

Quant is a technology provider, delivering enterprise-grade interoperability for the secure exchange of information and digital assets across any network, platform or protocol, at scale. Quant’s Overledger OS is the world’s first DLT operating system that complements and connects existing systems and DLTs, to drive innovative and efficient growth for companies, public entities, and regulatory bodies alike. Headquartered in London, UK, Quant is recognised as a Gartner Cool Vendor 2019, and is committed to unleashing the power of systems that are as connected as the world we live in. The Quant Network team developed Quant as a cryptocurrency token based on the Ethereum blockchain. The solutions offered by Quant include Overledger OS and GoVerify. According to the whitepaper, the initial goals of the Overledger project were to develop an interface to connect the world’s networks to multiple blockchains, bridge existing networks to new blockchains, and to develop a blockchain operating system with a protocol and platform that allows developers to create next-generation multi-chain applications. Their proposition for GoVerify is to allow people to verify and check whether any emails, SMS, mail, or phone calls received appear as legitimate and actually from the stated sender.
Zcoin (XZC) is an open-source privacy-focused cryptocurrency token that launched in Sep 2016. Zcoin originally pioneered the use of Zerocoin to enable privacy but has since transitioned to a scheme called Sigma which is based on a paper by Jens Groth and Markulf Kohlweiss that reportedly allows greater scalability and removes the need for trusted setup in Zerocoin. With Zcoin’s Sigma feature, only the sender and receiver would be able to ascertain the exchange of funds in a given transaction, as no transaction histories are linked to the actual coins. Zcoin is also the creator of the Lelantus privacy protocol which improves Sigma's privacy and functionality.
