What we talk about when we talk about MOS public chain

Since the development of the blockchain industry, using decentralized technology to solve various problems , especially the necessity and pain points in the financial field, seems to become commonplace. Despite the emergence of various blockchain projects , there are still very few projects that can provide users with decentralized financial services through technology . Admittedly, to become a safe and efficient financial public chain, there are a lot of problems to be solved . Only the two standards of safety and convenience can exclude many projects.

However, the extremely high threshold did not stop all projects. As the world’s leading financial public chain, MOS (Mega Operation System) technically solved the two problems that lie in front of the blockchain project, security and convenience , and created the same qualitative evidence through MRC20 and non-homogeneity through card MRC21 , to provide users worldwide just, fair, efficient and transparent block chain finance infrastructure and services .

Convenience — Complete MOS cross-chain protocol by domain

Cross-chain modules are an important technical component of MOS. With the continuous increase of blockchain projects, how to complete fast transfers across chains has become a major problem facing financial public chains. The cross-chain module of MOS uses a domain structure, which perfectly solves the cross-chain problem.

As a decentralized financial public chain developed by Molecular Future team, MOS inherits Molecular Future sub-domain structure and defines both heterogeneous chains and isomorphic sub-chains as sub-domains. All token transmissions in each sub-domain will be processed by MOS to ensure that MOS can track the total number of tokens held by each sub-domain. The transactions between sub-domains are called cross-domain transactions, and the ICT protocol is adopted to ensure that every link of the transaction can be confirmed in time and safely. In this process, in order to minimize the risk, the sub-domain tokens will be locked as a deposit for cross-domain transfers. The operation of the MOS cross-chain module is the result of the joint action of smart contracts, sub-domain governance, and communication nodes.

For example, when account a in subdomain A attempts to initiate a transfer to account b in subdomain B, the transfer information will first be sent by the cross-chain module to the MOS main chain, and then the main chain will verify the authenticity of the information and then send it to the responsible subdomain The communication node of B is then sent to subdomain B. Subsequently, new tokens prefixed with B and suffixed with the assets of the original asset subdomain A will be minted on subdomain B, the amount corresponding to the assets sent by account a, and send assets to the account b. Finally, when multiple nodes in sub-domain B confirm the completion of the transaction, a successful transaction message will be sent to the transaction contract in sub-domain A.

When other chains are connected with MOS (such as some chains have not yet supported the split domain protocol), MOS uses the Bancor protocol to map tokens to complete the cross-chain process and achieve fast cross-chain transactions. Through the cross-chain module, MOS perfectly solves the cross-chain transaction problems that many financial blockchain projects have not solved .

Security — use layered consensus to create an efficient blockchain network

In order to solve security problems, the MOS chain uses the innovative Octahedron PBFT + Raft + VRF hybrid consensus algorithm. Octahedron PBFT is Octahedron Practical Byzantine Fault Tolerance (Octahedron Practical Byzantine Fault Tolerance) algorithm, which can manage the nodes in different domains, so as to build a consensus among the super departments. Raft is a transaction broadcast consensus within the Super Department cluster. The algorithm uses a random leader to achieve rapid broadcast of transactions. VRF is randomly ordered accounting mechanism, a portion between the block policy set by the certificate of interest in the PoS (Proof of Stake) to form a final consensus restrict each other.

MOS’s hybrid consensus algorithm can maximize the role of each algorithm. Octahedron PBFT + Raft + VRF can work together to balance security and consensus efficiency to ensure the efficiency of block generation and transfer security on the chain. Simply put, Octahedron PBFT is responsible for node consensus, that is, on-chain governance; Raft is responsible for quickly broadcasting transaction information; VRF is responsible for managing block generation to ensure the smooth progress of block generation on the MOS chain .

Through the hybrid consensus algorithm, MOS can effectively prevent the Sibly attack while effectively guaranteeing extremely high security, extremely low probability of fork, extremely short confirmation time, low energy consumption and high scalability. The rational use of VRF sorting technology enables MOS to achieve stochastic and high-quality sorting and accounting while achieving stable and non-declining node transaction performance when TPS exceeds 2000. At present, according to the test, the TPS value of the MOS chain has reached 1 —2x104, which is currently the most advanced blockchain that can perform nearly “perfect” transaction performance . Compared with other public chains that use PoW , PoS, and DPoS , MOS guarantees to the greatest extent that users will not be “always stuck on the road of billing”.

Multiple account types — ensure comprehensive on-chain financial services

To provide users with more sophisticated financial services, MOS in the main chain set three pass card types, including MOS main currency, MRC20 and MRC21 .

MRC20 (homogeneous digital assets) and MRC21 (non-homogeneous digital assets) are two types of digital asset specifications on the MOS main chain. The so-called homogenous digital assets mean that there is only a quantitative change in the exchange, and the nature of the currency has not changed. For example, during the exchange of virtual coins in the game, only the change of the buyer’s virtual coin and the increase of the seller’s virtual coin occur during the exchange process . The so-called non-homogeneous digital assets mean that each asset is unique and indivisible. For example, real estate in the game, each set has unique properties, and real estate cannot be split into smaller asset units.

Users can issue tokens on MOS through MRC20 and MRC21 , however, the operations that can be completed through the tokens issued through MRC20 and MRC21 are also slightly different. The MRC20 specification not only provides information such as the total supply of tokens, account balances, and transferred tokens , but also adds support for stable coins ( additional issuance of tokens and destruction of tokens ), and also realizes the function of freezing and unfreezing tokens. To meet the supervision of certain tokens. MRC21 can support token query and transaction functions in smart contracts, but users cannot destroy or freeze tokens.

Through MRC20 and MRC21 , MOS main chain can meet the needs of users in different aspects and provide users with more comprehensive financial services.


The advent and development of blockchain technology has provided people with a level playing field and financial users the right to fully control their assets . MOS is the public blockchain of blockchain financial services that emerged at this opportunity. MOS uses a hybrid consensus algorithm, domain management and multiple types of accounts to achieve a perfect combination at the ledger level, smart contract level, unstructured data storage level, and user interface. Based on the professionalism of financial services, it will create a function A complete financial public chain with advanced technology and excellent performance.
