MintCoin is a new Proof of Work (POW) / Proof of Stake (POW) hybrid cryptocurrency coin. It's objective is to become the next innovative, secure, and energy efficient cryptocoin in the market. MintCoin is distributed using a fast POW distribution mechanism, and after 5 weeks, it becomes a pure POS coin. This makes the coin completely energy efficient in order to sustain itself, not having to depend on resource intensive mining rigs. MintCoin now runs on 100% Proof-of-Stake to secure the network. After the year 2016, stakers will receive a fixed 5% indefinitely as reward for securing the network. PoS variable interests: - 1st year: 20% - 2nd year: 15% - 3rd year: 10% - 4th and subsequent years: 5% MintCoin is often compared with its close counterpart - Peercoin and NXT
CommerceBlock is a public blockchain infrastructure company that is architecting a platform that allows anyone to build and use financial products and services historically reserved for commercial banking customers. The CommerceBlock network will be the first technology platform that provides a combination of trust minimal trade, decentralised contract execution, on-chain derivatives, and asset-backed token issuance to public blockchains. The advent of the Bitcoin protocol has enabled permission-less financial innovation. CommerceBlock’s product offerings provide a suite of tools that enables anyone to build and use services that construct contracts, manage trade flows, engage in multiparty dispute management, issue assets, and hedge currency risk. Developers and end users will be able to manage all stages of a business interaction and fulfil their contractual obligations by utilising the CommerceBlock platform. These services will be integrated into infrastructure we have already implemented. We have released the first open-source implementation of the pay-to-contract and homomorphic address protocol outlined by Timo Hanke and Ilja Gerhardt. The protocol has been designed in such a way that all business logic, customer funds, and trade details are managed on the client side meaning at no point does CommerceBlock have access to customer funds or private information.
