One of the few unique advantages of IOS is the use of "proof of likelihood" as a consensus mechanism. Can someone tell how this mechanism works?
Q: What is IOS?
A: The IOS (Internet of Services) is a next-generation, decentralized ecosystem for online service providers and users with safeguarded and fast transactions based on blockchain technology.
Q: Is IOS based on POS?
A: Actually, IOS is based on POB (Proof of Believability), an advanced version of POS (Proof of Stake).
Q: What is the difference between POB and POS? And why does IOS use POB?
A: POB and POS are similar. Unlike proof of work, the proof of stake achieves high security of the network without expending significant electricity costs. However, under the POS mechanism, token holders have the same fixed costs ( running the computer) and their earnings are related to the amount they held. Under such a mechanism, small amount token holders tend to step out gradually while larger ones gradually hold more tokens. This goes against the concept of the decentralization of the blockchain. POB introduced the concept of Servi on the basis of POS. In addition to the amount of tokens held, contributions are also incorporated into the believability considerations. Users can get a certain Servi by evaluating the services provided by the other party or making a special contribution. These initiatives are designed to promote a balance between nodes and encourage more nodes to join community maintenance and, eventually, realize a high degree of decentralization at a low cost and high speed.
Q: Which consensus protocol is used in IOS?
A: IOS uses a faster graded Byzantine Fault Tolerance mechanism.
Q: What is the EDS (Efficient Distributed Sharding) and how does it offer IOS with ultra-high TPS.
A: EDS is a blockchain network sharding technology initiated by IOS. With EDS, IOS divides all active nodes in the network into many subnets ("shards") dynamically, non-duplicately, and evenly. At the same time, this mechanism can guarantee the operation efficiency of the sub-network and ensure that there are enough effective nodes in each sub-network to verify the transaction. Each sub-network will only be responsible for verifying the transactions originated within this network in order to achieve the purpose of handling multiple transactions simultaneously, which greatly enhances the efficiency of network verification transactions.
Q: Is IOS infrastructure linear scalable?
A: Yes. Based on the EDS, transactions do not need to broadcast through the entire block chain but only through a shard. When new nodes join the IOS network, new sharding forms and the processing capacity increase at an almost linear rate.
