pTokens are digital assets that are transparently pegged to another underlying asset. pTokens serve as a Cross-Chain token wrapper that allows users to more easily transfer value between different blockchains. Users can deposit a certain amount of the underlying asset (such as BTC or EOS) and request the equivalent pTokens that are pegged to them 1:1, such as pBTC or pEOS. Token holders can then take advantage of the Ethereum network by more easily exchanging them into ERC-20 tokens.

The Kava token fuels the Kava.io cross-chain collateralized debt platform. Kava’s multi collateral CDP system allows users to collateralize a variety of assets so that they can increase their exposure to favorable trading conditions in volatile markets. The Kava platform is secured by over 100 validators and uses the Tendermint consensus algorithm.

Ontology is a network designed to be operated across multiple blockchains. Its main focus revolves around trust issues, and it provides identity verification and reputation management capabilities. Ontology's goal is to be a platform for decentralized trust systems in businesses. Their distributed network is set up to facilitate cooperation between different projects in a trust ecosystem. Ontology's framework allows users to customize different public blockchains for different applications. Ontology has a two-token structure. ONT is the utility token of the network that can be used to generate Ontology Gas (ONG). Ontology has an innovative consensus mechanism called Verifiable Byzantine Fault Tolerance (VBFT). It combines elements of Proof-of-Stake (PoS), VRF (Verifiable Number Function), and Byzantine Fault Tolerance (BFT). The VBFT consensus mechanism will select nodes that meet certain conditions, and will verify transactions.
