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.UMA defines an open-source protocol to create and verify trustless financial contracts, making it easier to create financial DApps.The Hedera Hashgraph consensus algorithm aims enable DApps where precise ordering and time recording of transactions is important.

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.

The UMA token is used to enable holders to participate in community governance issues and to help resolve contract disputes on the UMA platform. UMA is designed to be a decentralized financial contracts platform, and is an abbreviation of Universal Market Access. Their goal is to build the financial infrastructure that will make creating decentralized financial services easier. UMA provides a variety of smart contract templates as well as a decentralized oracle that can be used to validate payouts related to financial contracts.

Hedera Hashgraph is a blockchain network that was designed to allow developers to create DApps that require higher throughput and faster settlement. Hedera uses its own consensus protocol that assigns every transaction a consensus time that is calculated as the median of the times at which each node in the network first received it. The network is powered by the HBAR coin.
