The POA Network is an Ethereum-based platform that offers an open-source framework for smart contracts. The project is an Ethereum sidechain that uses Proof of Autonomy as its consensus mechanism, relying on a set of pre-selected validators to secure the network. The validators' identity will be public. 

Its purported benefits are the flexibility to code in Ethereum standards with the benefits of scalability and interoperability in blockchain networks. 

The POA Network will allow organizations to build their own networks with their own validators and developers to deploy DApps.

xDai is a cryptocurrency that is pegged to the US dollar. The xDai chain is a stable payment blockchain that is designed for fast and inexpensive transactions. STAKE is secured by proof-of-stake consensus. xDai was founded on Oct. 1, 2018.

STAKE is a multi-chain staking token that is designed to secure the payment layer. Staking allows validators and delegators to provide transaction consensus and receive staking incentives for block production. It is only required for consensus providers, not everyday on-chain transactions.

xDai was created by the POA Network, an open-source public side-chain of Ethereum founded in April 2017. It offers a framework for smart contracts which provides developers with an easy and effective way to code on Ethereum, while also leveraging the POA Network capabilities.

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.

Populous is a network designed to offer small and medium-sized enterprises (SMEs) invoice liquidity for up to 90 days. Launched in 2017, Populous is designed to enable peer-to-peer (P2P) interaction between enterprises, boost liquidity and solve problems with working capital for SMEs.

By relying on blockchain technology and smart contracts, the Populous network facilitates decentralized communication between businesses and allows them to share liquidity pools. According to the network’s official whitepaper, there is a need for liquidity in the sector, and Populous is trying to bring the solution. By providing short-term liquidity to enterprises through P2P lending, the network gives enterprises quick access to capital, which cannot be achieved by waiting for customers to settle invoices.
