Rocket Pool is a next generation decentralised staking network and pool for Ethereum 2.0 Rocket Pool is a self-regulating network of node operators; it automatically adjusts its capacity to match demand. The Rocket Pool protocol token is used to maintain an optimal capacity by: Increasing capacity when needed, by incentivising node operators to join. Decreasing capacity when not needed, by disincentivising node operators from joining. In addition to depositing ETH, a node operator is required to deposit a set amount of RPL per ether they are depositing. This RPL:ether ratio is dynamic and is dependent on the network utilisation. E.g: If the network has plenty of capacity, then node operators need more RPL to make deposits. It gets progressively more expensive in terms of RPL to make node deposits when the network does not have enough ETH from regular stakers to be matched up with node operators. This helps prevent several attack vectors outlined in the whitepaper and keeps assignment of ether ‘chunks’ to nodes quick. If the network is reaching capacity, then node operators need less RPL to join as the network needs more node deposits to be matched up with regular users deposits. If the network is maxed out and needs node operators to join quickly, it even drops to 0 for the first one to make a deposit.
The ArcBlock project was created to create the first Blockchain ecosystem in the world. Develop and develop decentralized applications (DApp) according to objectives. ArcBlock, one of the ICO projects emerging in early 2018. Just launched on 3/1/2018, ArcBlock has quickly attracted the attention of technology as well as investors. ArcBlock brings great technological advancements that will open the third generation of blockchain applications. Arcblock work by bridging the gap between different blockchains and their respective ecosystems has not been easy. There are some solutions which attempt to solve this problem, but it is evident there is plenty of room for competition in this regard. Building an open chain access layer capable of spanning multiple new and existing blockchains is a very interesting business model. Building a new ecosystem meant to connect various chains will not be easy. As of right now, the team has completed its token sale, and the first public release candidate for the Open Chain Access Protocol will be released in Q3. Early 2019 will herald the introduction of more technical features and an Ethereum Blocklet prototype.
