Consensus Layer
The consensus layer, often referred to as Layer1, originally was responsible for validating and ordering transactions in the block. Recently, some projects have proposed ways to separate computation and data availability capacities from the consensus layer making it dedicated to data authentication. However, the requirement of composability among Defi smart contracts still calls for scalability of the transaction processing of the consensus layer.
Algorand
Algorand is a pure proof of stake blockchain cryptocurrency protocol that is scalable by solving the blockchain trilemma with its consensus mechanism. The Algorand platform supports smart contracts, and its consensus algorithm is based on proof of stake and a Byzantine agreement protocol.
Avalanche
Avalanche is the fastest smart contracts platform in the blockchain industry, as measured by time-to-finality.
Beam
Beam is a privacy coin that aims to explore confidential DeFi. It utilizes the Mimblewimble protocol which conceals the values and metadata of transactions, while reducing blockchain bloating and improving scalability. With the latest implementation of LelantusMW it aims to bring privacy and anonymity in all fronts.
Flow
Originally conceived by the team behind CryptoKitties, Flow today is a decentralized network supported and built on by a growing community of brands and Web3 builders.
Octopus
The Octopus Network is a multichain cryptonetwork for launching and running Web3.0 application-specific blockchains — appchains. Appchains in the Octopus Network benefit from flexible and cost-effective leased security (LPoS), out-of-the-box multichain interoperability, complete infrastructure, and a ready-to-be-engaged community. The core of the Octopus Network is the Octopus Relay — a set of smart contracts running on the NEAR blockchain, aka mainchain, that implements the security leasing market.
PlatON
PlatON, initiated and driven by the LatticeX Foundation, is a next-generation Internet infrastructure protocol based on the fundamental properties of blockchain and supported by the privacy-preserving computation network. “Computing interoperability” is its core feature.
Polkadot
Polkadot is built to connect private and consortium chains, public and permissionless networks, oracles, and future technologies that are yet to be created.
Silvermint
Silvermint is a leaderless, scalable, and secure proof-of-stake blockchain with smart contracts and censorship resistance. Designed for developers, by developers, Silvermint offers lightweight and independent architecture making it easy to adopt incrementally.
