Deployment diagram of underlying server of blockchain

1. Triporg travel: a travel service application using the underlying technology of blockchain, which can provide travel prepaid services such as train tickets and air tickets.

2. LF CEO Ma Haobo said in the "cannon interview": the problems urgently solved by the underlying facilities of the next generation blockchain are very similar to those of Ethereum. It is an underlying decentralized computing platform. On the platform, users can easily deploy smart contracts and run them, but? LF thinks that Ethereum has three problems and hopes to solve them. The first is its overall low performance and TPS; Second, resources are not isolated. When crowdfunding for a certain contract is very popular, Ethereum network will block and other contracts cannot be executed; The third problem is reflected in the governance structure, who this blockchain belongs to, how it develops, and how to solve the problem of bifurcation.

3. Just to learn a little, Heshu software was founded in 2017. It has its own blockchain technology laboratory, focusing on blockchain technology scenarios and application development. For example, the underlying architecture of laikelib blockchain allows users to develop their own independent applications and systems on the chain, which is similar to Ethereum. The advantages of laikelib are small capacity, short block out time of 2 seconds, diversification and independent research and development. The response is still good, and they have set up a technical team composed of experts in the fields of data science, blockchain, cryptography and data analysis. The others are not clear. I hope they can help you and hope to adopt them!

4. Blockchain is a new decentralized protocol, which can safely store transactions or other data. Information can not be forged or tampered with, and can automatically execute smart contracts without the audit of any centralized organization. Transaction can be digital currency such as bitcoin, or digital assets such as creditor's rights, equity and right, which greatly reces the trust cost and accounting cost of real economy and redefines the property right system in the Internet era. At present, aelf is a well-known blockchain project of the underlying architecture, which represents the future development direction.

5. The hierarchical structure of blockchain
1, data layer / data layer
the data layer mainly describes the physical form of blockchain, which is a chain structure starting from Genesis block on blockchain, including block data, chain structure, random number, time stamp, public and private key data on blockchain, and is the lowest level data structure in the whole blockchain technology
2. Network layer / network layer
the network layer mainly realizes the mechanism of distributed network through P2P technology, and the network layer includes P2P networking mechanism, data dissemination mechanism and data verification mechanism. Therefore, blockchain is essentially a P2P network with automatic networking mechanism, and the communication between nodes is maintained by maintaining a common blockchain structure
3. Consensus layer / consensus layer
consensus layer mainly includes consensus algorithm and consensus mechanism, which enables highly dispersed nodes to reach consensus on the effectiveness of block data efficiently in the decentralized blockchain network. It is one of the core technologies of blockchain and also the governance mechanism of blockchain community. At present, there are at least dozens of consensus mechanism algorithms, including workload proof, rights and interests proof, rights and interests authorization proof, burning proof, importance proof and so on
data layer, network layer and consensus layer are the necessary elements of building blockchain technology. Without any layer, it can not be called a real blockchain technology
4. Incentive layer / activator layer
the incentive layer mainly includes the issuing system and distribution system of economic incentive. Its function is to provide certain incentive measures, encourage nodes to participate in the security verification work in the blockchain, incorporate economic factors into the blockchain technology system, encourage nodes that comply with rules to participate in bookkeeping, and punish nodes that do not comply with rules
5. Contract layer / contract layer
the contract layer mainly includes various scripts, codes, algorithm mechanisms and smart contracts, which is the basis of block chain programming. Embedding the code into the blockchain or token, realizing the smart contract that can be customized, and automatically executing without a third party when certain constraints are met, is the foundation of the blockchain's distrust
6. Application layer / application layer
the application layer of blockchain encapsulates various application scenarios and cases, which are similar to applications on computer operating system, portals on Internet browsers, search engines, e-malls or apps on mobile phones. The blockchain technology applications are deployed on Ethereum, EOS and qtum, and are implemented in real life scenarios. The future programmable finance and programmable society will also be built on the application layer
incentive layer, contract layer and application layer are not necessary factors for each blockchain application, and some blockchain applications do not completely include the three-tier structure.

6. Laikelib main chain: the main chain of laikelib mainly deals with the interaction between the application business model and the application scenario. Laikelib side chain: around the main chain, any application system can be developed in the side chain for users to use.

7. Bitcoin.cz's first large mine, slush's own Chinese course! The content is very detailed. It's a very good choice for those who don't understand foreign languages or bitcoin~

8. All mining machines have such a normal phenomenon, the calculation of mining machine chip is not a stable output process, as long as the average computing power and daily income are stable
in addition, the computing power of mining machinery will fluctuate e to the status of mining machinery, working environment, network instability and other factors. The mine management personnel need to pay attention to check all relevant factors to protect the stability of income.

9. Hunan now has two well-known blockchain projects: one is the SMIC blockchain public service platform in Changsha, and the other is the blockchain real estate platform in Loudi. The promotion and popularization of these two platforms does not mean that the whole of Hunan has entered the era of blockchain 3.0. It can only be said that what they are doing belongs to the procts and applications that should be in the era of blockchain 3.0.

10. At present, the underlying infrastructure of blockchain is very few, but think is one of them
