Raven is creating a network of compute nodes that utilize idle compute power for the purposes of AI training where speed is the key. AI companies will be able to train models better and faster. We developed a completely new approach to distribution that speeds up a training run of 1M images and brings it down to a few hours. We solve latency by chunking the data into really small pieces (bytes), maintaining its identity, and then distributing it across the host of devices with a call to action: gradient calculations. Other solutions require high-end compute power. Our approach has no dependency on the system specs of each compute node in the network. Thus, we can utilize idle computer power on normal desktops, laptops, and mobile devices allowing anyone in the world to contribute to the Raven Protocol network. This will bring costs down to a fraction of what you need to pay for traditional cloud services. Most importantly, this means Raven will create the first truly distributed and scalable solution to AI training by speeding up the training process. Our consensus mechanism is something we call Proof-of-Calculation. Proof-of-Calculation will be the primary guideline for the regulation and distribution of incentives to the compute nodes in the network. Following are the two prime deciders for the incentive distribution: Speed: Depending upon how fast a node can perform gradient calculations (in a neural network) and return it back to the Gradient Collector. Redundancy: The 3 fastest redundant calculation will only qualify for receiving the incentive. This will make sure that the gradients that are getting returned are genuine and of the highest quality.

MultiversX is a complete rethinking of public blockchain infrastructure, specifically designed to be secure, efficient, scalable and interoperable. MultiversX’s main contribution rests on two cornerstone building blocks: 1) A genuine Adaptive State Sharding approach: effectively partitioning the chain state into multiple shards, handled in parallel by different participating validators; 2) Secure Proof of Stake consensus mechanism: an improved variation of Proof of Stake (PoS) that ensures long term security and distributed fairness, while eliminating the need for energy intensive PoW algorithms. Our technology is aimed at developers, wide public and enterprises. Developers can use it to create decentralised applications and run smart contracts on our blockchain network. The wide public can use MultiversX as a user-friendly gateway to the digital economy. MultiversX is also attractive for businesses seeking an enterprise solution that can lower (human capital based) costs with benefits such as speed, security and scalability.

Harmony is a fast and scalable blockchain. Harmony recently launched on Binance and shipped Day ONE Mainnet. We are crazily recruiting Rust/Go language enthusiasts, protocol researchers and database hackers. Apply at harmony.one/careers! See https://harmony.one/whitepaper for our latest research and roadmap. Harmony is a fast and secure blockchain with key innovations in state sharding and peer-to-peer networking. Its sharding uses secure proof-of-stake and decentralized randomness, and its networking achieves optimal cross-shard routing and fast block propagation. Harmony helps businesses build marketplaces of fungible tokens (such as energy credits and loyalty points) and non-fungible assets (such as game collectibles and real estate). Harmony is applying zero-knowledge proofs for data sharing while preserving the consumer’s privacy. Common industry use cases include ad exchanges, credit ratings and many other data consortia that would otherwise take many years to form among competing companies.

BEAM is based on Mimblewimble – an elegant protocol released by an anonymous developer in 2016. Named after a tongue-tying spell from the Harry Potter saga, Mimblewimble uses Pedersen Commitment scheme for full anonymity and zero-knowledge range proofs to ensure validity of transaction amounts. To enhance privacy and reduce the blockchain size, Mimblewimble merges all intermediate outputs within a single block and across multiple blocks, thus only storing the current UTXO state and making the blockchain size an order of magnitude smaller than in other leading currencies. BEAM team implemented Mimblewimble from scratch using C++. BEAM blocks are mined using memory-hard Equihash Proof-of-Work algorithm. The block time is 1 minute on taver- age.
