Pool of Stake is creating a safe pool for Proof of Stake coins, the future of blockchain. Qtum, Stratis, Universa and soon Ethereum holders can unite in the Pool of Stake and start staking together. Pool of Stake aims to operate in all types of PoS blockchains- Smart Contract platforms or blockchains with a delegated mechanism. The main goal for Pool of Stake is to increase the profits for small stakers by enabling a trusted environment to pool funds together. For this purpose, two ERC-20 tokens are used. First, the PSK token that gives discounts an rewards withdrawal fees. Second, an IOU token that acknowledges the user’s investment. The PSK platform will provide an analytics tool via a smart i.o. database that will allow members to track, control and optimize their investments. In this white paper, we explain the implementation of Pool of Stake and its services. We elaborate the governance vision which will be developed in the coming months to ensure that the PSK community remains fair and agile. We then present detailed information relevant for the upcoming ICO starting 20 July 2018. We conclude the white paper with a review of our current accomplishments and an overview of projected milestones.
