Polkadot
Polkadot is a blockchain network being built to enable Web 3.0, a decentralized and fair internet where users control their own data and markets prosper from network efficiency and security. Polkadot was founded in 2016 by Gavin Wood, former Co-Founder and CTO of Ethereum. Polkadot’s technology addresses the major issues that have stymied blockchain adoption in recent years. Polkadot’s software development toolkit, Substrate, created by Parity Technologies, makes it easy for blockchain developers to build their own custom, fit-for-use blockchains. Polkadot also enables multiple blockchains to communicate between each other, allows for easy upgradeability, and introduces “shared security”, a plug-and-play network security model that allows developers to focus on the technology and avoid spending time and resources recruiting a set of operators to run a new blockchain.

Meter
Meter is a high performance infrastructure that allows smart contracts to scale and travel seamlessly through heterogeneous blockchain networks. Meter is a Layer 1 and Layer 2 blockchain protocol. The Meter system consists of two tokens: MTRG, the governance token (eMTRG is the ERC20 version), and MTR, the low-volatility currency token.
Financial assets should flow freely among blockchains. Meter’s HotStuff-based consensus allows 1000s of validator nodes, making Meter the most decentralized Layer 2 for Ethereum. Meter processes thousands of transactions per second and transactions are confirmed almost instantly. Meter Passport allows assets and smart contracts travel and communicate across heterogeneous blockchains for the best price, liquidity and yield. Meter is an Ethereum Compatible with unique enhancements. Unlike other Layer 2, DEXes build on Meter are front running/MEV resistant, fast and uncensorable.

Celer Network
Celer Network is a layer-2 scaling platform that brings fast, secure and low-cost blockchain applications on Ethereum, Polkadot and other blockchains to mass adoption. Celer launched the world’s first Generalized State Channel Network and continues to push the frontier of layer2 scaling with advanced Rollup technology. Core applications and middlewares like cBridge, Layer2.Finance and more ecosystem applications built on Celer have attracted more large audiences in DeFi, blockchain interoperability and gaming space. Layer2.Finance tackles the two largest challenges preventing DeFi from reaching mass adoption, the extraordinarily high transaction fees and being very difficult to navigate and use. cBridge is a multi-chain network that enables instant, low-cost and ANY-to-ANY value transfers within and across Ethereum’s layer-2 chains, Ethereum main chain and in the future, other layer-1s, and layer-2 on top of those other layer-1 chains.
