[Short general description]: YGGDRASH aka a world tree, is a channel connecting all blockchains. The purpose of YGGDRASH project is to connect all blockchains using a Trust-based Multi-dimensional blockchain, and hopes to redesign all services on the Internet into a blockchain platform.
Yggdrash’s main-net is called STEM, and its cryptocurrency is YEED. It is a trust-based blockchain ecosystem where each branch is governed by reputation to ensure integrity.
[Main problems tackled]:
1) Transaction processing performance, abusive, self-interest driven competition between block verification nodes, and sync speed of blockchain - optimized performance of main chain processing
2) Independence and processing performance of each blockchain is guaranteed - solving selfish mining competition system
3) Solving selfish mining competition and ensuring trust or reputation based economic incentives - YGGDRASH will resolve the selfish competition problem by applying DPOA. The verifier of YGGDRASH blockchain has the authority to determine the policies of our YGGDRASH network, rather than receiving incentives of cryptocurrency through PoW and PoS.
4) Interoperability, scalability between block chains are guaranteed - YGGDRASH is a blockchain platform that can connect different blockchains which satisfy business needs of users, and the stem chain and branch chain serve those roles. The stem chain contains address information of all branch chains connected to the YGGDRASH network as if using domain services when we search on 18 Google. In order to connect to other branch chains, the branch chain selects the service of other branch chains needed to its business using the information contained in stem chain.
[Main contribution proposal]:
1) YGGDRASH consists of Stem chain and Branch chain; the Stem chain provides the blockchain ecosystem where all the Branch chains communicate and be fused.
2) Advantages of YGGDRASH - the smart contract data capacity issue is resolved, improvement of processing performance through blockchain network sharding, Akashic system –improvement in node sync speed by applying BRA (Block Reassembling Algorithm)
3) The File Sharing on P2P Network - Solving the issue of storage capacity
4) Blockchain Starter & Smart Kit - provides blockchain development toolkits for independent blockchain developers. Each toolkit is customized for blockchain development that satisfies the schedule, flexibility and applicability, and convenience of development depending on business requirement and strategy.
1) Governance in YGGDRASH - Consensus Algorithm - YGGDRASH will develop DPOA (Delegated Proof of Authority), a self-consensus algorithm, to ensure faster performance than any other consensus algorithms by selecting the node with the highest reputation score as a representative through the reputation evaluation chain.
2) Governance of Representative - the representative nominee is selected through the YGGDRASH’s reputation evaluation chain and the representative is finally elected by the committee of YGGDRASH representatives, attending more than 3/4 of members and agreed by more than half of those attendees.
3) Incentive for Representative - Base on a multidimensional blockchain characteristic, there is no direct monetary compensation policy for those representatives in YGGDRASH network. However, YGGDRASH honors a representative and benefits creating immunity chain without consuming YEED and paying less or no fee in YGGDRASH network.
