Moke public chain and Ethereum

1.

what is Ethereum:

Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. blockchain technology is one of them
Ethereum platform can safely run any program users want

advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum

what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application

The design of Ethereum is very flexible and adaptable

Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields

blockchain applications of Ethereum

Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc

Ethereum has achieved more than 100 blockchain applications by many start-ups

Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged

the relationship between Ethereum and blockchain:

Ethereum is a programmable blockchain

Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes

in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency

like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"

2. Many blockchain projects are developed on the basis of Ethereum's open source technology. Ethereum is a common public chain technology, and the deployment of applications on Ethereum has high requirements for developers. Developers need to consider many technical details and business processing logic, as well as security vulnerabilities such as smart contract overflow
the trust union credit alliance chain is located in the financial public chain, which is oriented to the high-frequency financial application scenarios in the field of credit and assets. It does not use eth, EOS, Neo and other general public chains, but uses the account structure of star network, adopts the lightweight intelligent contract layer, and the whole technical architecture is molarized according to "high aggregation and low coupling", This enables the trust union credit alliance chain to adapt to the requirements of rapid development, rapid implementation and timely response of Internet financial procts.

This is two different concepts. According to different standards, blockchain can be classified into three categories:

& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain

 &# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain

 &# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain

the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process

6. Mother of all chain (MOAC) blockchain (hereinafter referred to as "moacchain", transliterated as "Moke chain" in Chinese, also known as "the mother of many chains") is an open-source blockchain platform. It supports multiple seed blockchains on P2P network through hierarchical configuration structure. It is developed by the top team of blockchain experts in Silicon Valley, breaking through the asynchronous contract call, asynchronous contract call, and multiple seed blockchains Contract fragmentation processing and cross chain operation are the current instry problems. The expansion capacity and contract processing speed of the platform are far better than the current smart contract platform. It is a blockchain proct that can really deploy commercial applications

the reason for the emergence of Moke is that Ethereum, the hottest smart contract platform at present, has insufficient speed and expansion capacity to meet the needs of a large number of token project applications. Compared with Ethereum's 7-14 transactions per second, Moke can achieve 100 times, even 1000 times under optimized conditions
how is Moke, as an "optimized Ethereum", realized technically<

01 layered verification
first of all, layered verification is adopted. Other systems either insist on pow, or insist on POS, or mix POW + POS, which can not effectively use the advantages of both and avoid the disadvantages of both. We use POW in the physical network and POS in the logical network of the smart contract, so that we can take both advantages into account, which can be called pop (POS over POW)<

02 fragmentation technology
the latest fragmentation concept of Ethereum, the main chain is basically unchanged, and a validator management contract is added to manage sharding interface and allocation. The main chain doesn't care what it looks like in sharding. The main chain only cares about the hash of your header. However, in order to achieve fragmentation in technology, according to the route planning of Ethereum, it will not come out until 2019

compared with Ethereum's single network, Moke has successfully broken through and adopted sharding technology, which can divide Moke into numerous logical subnets, making parallel computing possible, solving a major problem in the instry, greatly improving the processing speed, so as to achieve visa level transaction scale<

03 asynchronous call
Ethereum's synchronous smart contract call, the return of smart contract and block consensus are bound in the same block, resulting in the total amount of smart contract processing limited by block time. Moke adopts asynchronous smart contract call, so that the call and return can cross blocks without block time limit, which greatly increases the number of smart contracts to be processed at the same time

04 cross chain
by crossing blocks through asynchronous smart contracts, Moke can carry out atomic cross chain operation on blockchains with different block generation times, making Moke an underlying blockchain system with cross chain capability. Asynchronous call of smart contract can cross blocks from start to completion, and is no longer limited to one block. This greatly speeds up the throughput of MOAC, and has the function of cross chain of different blockchains

different blockchains have different block generation times. For example, if you set a contract to buy Ethereum erc20 token on the MOAC, you can cross the current block of the MOAC in 5 seconds, and then the contract will wait for Ethereum 25 second block to complete the corresponding transaction through off chain communication, and then complete the transaction in the N + 2 MOAC block. This kind of atomic transaction is completely different from the current transactions completed by various cross chain third-party roles through the establishment of an intermediate escrow account

in the contract, you can also define several confirmation blocks to complete the transaction. Other blockchain systems lack the function of asynchronous call contract, so they can't exchange atoms across chains, which is the advantage of MOAC

05 plug in and verify self built blockchain procts
the new idea means to build a new blockchain. We need to set up servers, develop teams, build communities, attract new users, and so on. We need to spend a lot of money to implement new blockchain ideas. After the inker chain goes online, these ideas can be easily tested on the inker chain, without huge additional costs<

06 never bifurcate
once blockchain procts are deployed and put into proction mode, it is difficult to add / modify / delete functions. Such a modification is either a soft fork or a hard fork. Dealing with bifurcation requires great effort and economic consequences. The architecture mode of Moke chain makes it possible to improve blockchain without bifurcation.

7. Now, MOAC's sub chain technology can solve this instry problem! Moke MOAC sub chain has been verified in the public beta, which shows that Moke MOAC is the only bottom public chain that supports issuing chain with money and issuing chain without money on the sub chain at the same time.

8. A low-level public chain which realizes the function of sub chain and is friendly to DAPP.

9. MOOC MOAC platform uses hierarchical multi blockchain architecture, blockchain fragmentation technology, sub chain intelligent contract and cross chain function to achieve this goal. The infrastructure of MOAC platform is the master chain running on the global public chain, which is responsible for intelligent contract management and sub block chain (sub chain). The sub chain also supports transactions based on various consensus mechanisms. The subchain is completely different from the side chain. The side chain is usually an independent chain, which can work independently of the main chain. It has its own peer-to-peer network. However, the number of nodes in the side chain is usually small, so it is very vulnerable to attack, and its security is several orders of magnitude worse than that of the main chain. Therefore, the side chain can only accommodate values consistent with its security level. In contrast, the sub chains on the parent chain are highly dependent on the peer-to-peer network connectivity and flow control of the parent chain. Therefore, it can provide the same level of security as the parent chain, while significantly improving the performance and flexibility of a single blockchain. In addition, the combination of sub chain and parent chain has unique advantages, such as flexibility, independence, high performance and cross chain function.
