What problem does this service solve?

Solana allows developers to create DApps with faster performance by separating the consensus process from the recording of transactions.Rise hopes to create a blockchain platform that will have faster transaction times and will handle larger volumes.ChainLink wants to solve the connectivity problem facing smart decentralized applications. By connecting smart contracts to external data resources, many potential use cases for blockchain can be opened up.

Company Description

The Solana blockchain uses an innovative Proof of History mechanism to confirm transactions that are recorded on the network. Solana is designed to separate the consensus process from the flow of transactions. This is done with a recursive, verifiable delay function that hashes incoming transactions, and recording information as a function of time. Every node on the Solana blockchain is assigned a cryptographic clock that enables the network to determine the time and ordering of transactions, without having to wait for consensus from other nodes. By separating the process of transaction verification from their recording, a higher throughput is achieved without sacrificing network security.

Rise is building a blockchain development platform with dPoS consensus. Their protocol uses a Delegated Proof-of-Stake (dPoS) consensus mechanism and will be powered by the RISE coin. They hope to significantly improve transaction times and reduce fees, while providing developers with a tool set to create DApps in several programming languages.

ChainLink is developing the LINK Network, which will enable connected smart contracts. LINK will provide smart contracts with a variety of external data and access to APIs. ChainLink's goal is to solve the connectivity problem that plagues smart contract based systems, and discourages mass adoption. Many decentralized applications are unable to connect with important external data sources due to limitations involving their consensus protocols. The LINK network wants to connect their smart contracts with external systems and APIs by using secure middleware.
