This article mainly introduces the relevant knowledge of what the core knowledge that must be mastered in learning blockchain technology is, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe that after reading this article, you must master the core knowledge of blockchain technology what the article will have a harvest, let's take a look.

Learning block chain requires understanding of network communication

At present, the block chain mainly involves unstructured peer-to-peer communication (P2P); it may be derived into structured P2P communication in the alliance chain in the future. In fact, point-to-point communication is to establish a virtual link, and the underlying physical link may change the corresponding path with the change of network jitter (related to the network condition, block size, the number of transactions in the block, etc.). Therefore, it is recommended to consolidate the basic knowledge of network communication.

Learning blockchain requires understanding of data storage

Most of the previous data storage methods are based on high-throughput key-value databases, but now with the development of blockchain technology, traditional relational databases (such as Mysql, Oracle) can also become storage media, and even some companies have begun to use big data platform (Hadoop+Habse) to build the underlying storage mechanism. The next generation of distributed version file system (IPFS) is also an important direction to be tracked.

Learning block chain requires an understanding of encryption technology.

It is mainly necessary to understand the basic principles of hash function and asymmetric encryption and the operation mechanism of digital signature, which is also the core encryption technology of blockchain. More importantly, national secret algorithms are used in financial systems at present, and SM2, SM3 and SM9 national secret algorithms corresponding to blockchain technology need to be understood.

Learning block chain needs to understand consensus mechanism

The first popular is the consensus mechanism of distributed systems in trusted environment (such as PaxOS and Raft), which mainly involves CAP theory. On the basis of preserving partition fault tolerance (Partition tolerance), there will be a tradeoff between data ultimate consistency (Consistency) and system availability (Availability). Blockchain technology mainly emphasizes that the consensus mechanism in a "de-trust" environment, including bitcoin workload proof mechanism (PoW), point coin equity proof mechanism (PoS), bitstock share authorization proof mechanism (DPoS), as well as the later development of practical Byzantine fault-tolerant algorithm (PBFT) and the continuous evolution of related consensus algorithms require a long-term tracking and practice.

Learning block chain needs to pay attention to privacy protection.

The blockchain itself is a secure communication based on asymmetric encryption. However, the corresponding transaction relationship can be queried according to the "specific number" at the end of the transaction, and the identity information of the trader can be tracked through the routing table of the core router, the physical address of the network card (MAC address) and the international mobile device identification number (IMEI number) of the mobile phone, so as to crack the hiding of information in the dark network based on onion routing (Tor). Later, Monroe currency (Monero) based on ring signature, ZCash based on zero knowledge proof and homomorphic encryption technology gradually appeared. Whether it is ring signature, zero knowledge proof, or homomorphic encryption technology, it is somewhat difficult and obscure and belongs to a larger category. Generally speaking, if you have mastered the privacy protection technology, you can be regarded as a blockchain expert.

Learning block chain requires mastering security technology.

It mainly involves private key security, how to generate private key security algorithm or identity-based new private key generation algorithm. Later, we also need to track and study the security of intelligent contracts and the vulnerability attacks that Taifang block chain will suffer. The security of smart contracts may also require familiarity with the corresponding compilation principles and virtualization technologies.

Learning block chain requires understanding cross-chain technology.

Cross-chain technology refers to the interconnection of different structures and different types of block chains. Boca chain (Polkadot chain) and cosmic chain (COSMOS) are well-known in the industry, which belong to the cross-chain technical representative of heterogeneous block chain. Cross-chain technology can be divided into several subcategories, such as Boca chain (Polkadot chain), which uses block chain as message transmission medium, Ruibo Interledger protocol, which transmits communication messages through connectors between account books, and Aeternity, which supports cross-chain communication through state channel and routing.

To learn the block chain, you need to understand the technology under the chain.

If every transaction of the blockchain is completed on the chain, performance may be a major bottleneck in the blockchain system. So how to improve the performance of the blockchain system? It is a good development direction to complete a large number of micro-payments under the chain without the way of digital signature verification, which is called off-chain technology. To learn the off-chain technology of blockchain, you can focus on the lightning network corresponding to Bitcoin and the lightning network corresponding to Ethernet Fong.

Learning block chain needs to pay attention to some derivative technologies.

For example, the combination of single chain and multi-chain, referring to the editable blockchain technology introduced by British digital currency RSCoin; Accenture, subverts the unalterable nature (the need for bank rollback); IOTA's blockchain technology based on directed acyclic graph (DAG) (in fact, there is no longer the concept of chain), began to get rid of the traditional definition of blockchain and gradually moved closer to the "distributed ledger" technology.

Learning block chain needs to be combined with the actual industry.

The most important thing is that blockchain is just a technology. the real completion of blockchain learning is inseparable from in-depth study in the professional vertical field. Understanding blockchain is only superficial. Understanding industry + understanding blockchain is the real blockchain expert.
