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.Penta does not appear to solve any problems better than existing blockchain platforms.FOAM aims to to bring location data to blockchains and enable consensus driven mapping.

Token Stats

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.

Penta is developing a blockchain platform that DApps can be built on. It will have a Dynamic Stake Consensus (DSC) algorithm to confirm transactions. The Penta network is currently powered by the Ethereum-based PNT token.

FOAM is developing a blockchain-based location service protocol for embedding physical locations in Ethereum smart contracts. The FOAM network will use radio beacons and will provide incentives for decentralized location services that will be given by network participants. Users will stake tokens to become zone anchors, that will work with radio beacons to return location data to the network. FOAM's Proof of Location protocol will be used to confirm consensus on the location of objects and entities in space and time.
