Blockchain public chain project? What is a blockchain project

The public chain, as the name suggests, is very inclusive and fair, and the better the public chain project does in these two points, the more prominent it will be. At present, many common public chains sacrifice fairness for the speed of transactions, and are not optimistic. There is a project called Vanta Network, and their DSC technology claims to be both secure, democratized and fair, which deserves long-term attention, but they will only be open source at the end of the year, and the progress needs to be accelerated.

NEO, EOS, PNT, BTM, and ANT are all recognized projects with good public chain technology.

The positioning of zilliqa is the underlying public chainThe core competency is to significantly increase throughput TPS (i.e., transaction processing speed) through sharding technology. In the latest experiment, the ZilliQA test network has a processing power of 2488 TPS, which is more than 100 times faster than Ethereum's top speed of 20 TPS and 355 times that of Bitcoin! Through sharding technology, when there are more nodes in the network, the transaction processing speed will be higher, and when the number of nodes reaches tens of thousandsThe speed of transactions is expected to reach the speed of a centralized institution like Visa.

The token of the Zilliqa project, called ZIL, has been circulated and traded on 23 exchanges, and is supported by mainstream exchanges such as Huobi and Binance, so it is very convenient to participate. The maximum amount of ZIL is 21 billion, of which 12.6 billion will be released directly through the contract, and the other 8.4 billion will be released in the form of mining rewards within 10 years.

The Zilliqa mainnet was launched at the end of 2018 or the beginning of 2019, and the mining rewards are huge, especially in the early days. The cost of zilliqa mining electricity is only 1 9 of Ethereum, which is less energy consumption and more practical. In addition, mining can be done through GPU graphics card miners, and it can:At the same time, ZIL and ETH are double-mined, which brings higher returns to miners.

From an academic point of view, blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is essentially a decentralized database.

It first appeared in 1991 and was used by a group of researchers to timestamp digitized documents. In order to make these documents cannot be tampered with, it looks like a notary public using blockchain technology.

However, the technology has not played any role since, until 2009, when a man named Satoshi Nakamoto used blockchain technology to create the cryptocurrency Bitcoin.

A blockchain is a distributed ledger that is completely open to everyone, and it has an interesting property: once data is recorded in the blockchain, it is very difficult to change it. So how exactly does it work?

Let's first look at the composition of a single block.

Each block contains three important parts:Once a block is created, its hash value is uniquely determined, and changing the slightest bit of content in the block will cause its hash value to change dramatically. That is, when you need to check if a block has been tampered with, you only need to check if its hash value has changed.

If the hash value of a block changes, its content must have changed. It's not the same block again!

The third element contained in a block is the hash of the previous block, which allows a chain to be formed between blocks. And it can make the blockchain very secure. Let's take an example: Let's say we have a blockchain with three blocks.

In the blockchain industry, whether it is a practitioner or an investor, there must be no stranger to the public chain. Whenever a new project is born in the industry, it has to be more or less related to the public chain. But in fact, throughout the blockchain industry, there are not many mature and stable public chains.

At present, there are three main types of systems in the blockchain industry: public blockchain, joint blockchain, and private blockchain.

The public blockchain is often referred to as the public chain in the industry, which refers to the fact that any individual or group in the world can participate in the bookkeeping and transaction process of the entire system, and at the same time, Qi Hao with its transaction records can obtain the effective confirmation of the blockchain mainnet of the system. The public chain is the earliest and most widely used blockchain system in the industry.

The joint blockchain, also known as the consortium chain, the consortium chain system is not open source, but by a group within the designation of a number of pre-selected nodes as bookkeepers, the generation of each block is determined by all the pre-selected nodes, other nodes can participate in the transaction, but do not have the right to participate in the bookkeeping process, which is essentially similar to the financial industry's toot spike tube bookkeeping, which can be called a "semi-centralized" blockchain system. This kind of system is more stable, but it is not suitable for large-scale popularization and application.

A private blockchain is a private chain. This kind of system is more closed, and simply uses the underlying technology of the blockchain for the bookkeeping process, but its network system is not open source, but the developer has exclusive writing rights. The developer here can be a company or an individual.

At present, many traditional financial industries want to try private chain development, but their application products are still being explored.

Among the above three system types, the public chain system is undoubtedly the most eye-catching in the industry. Compared with the other two, the public chain has the advantages of open source, decentralization, and a wide range of ecological scenarios, and is also more conducive to global promotion and layout of the high index. However, due to various reasons such as technology, capital, and time, the research situation of the industry's public chain is generally not optimistic.

The three most well-known public chains in the industry, the Bitcoin public chain, the Ethereum public chain, and the EOS public chain, all have different problems. The closed system of the Bitcoin public chain forms an island of value, and the hard fork cannot be solved; Ethereum transaction congestion and high fees have always been difficult to solve; Within EOS, due to the lack of ecological scale, it is difficult to support excellent ecological applications, and at the same time, problems such as CPU skyrocketing and insufficient memory are gradually revealed.

All in all, in order to determine whether a public chain is reliable, it is necessary to understand whether the operation logic of the public chain network itself is stable, whether its ecological architecture capacity is sufficient, whether its community consensus is strong, and whether its application scenarios have long-term hematopoietic functions. Of course, at present, the blockchain industry is in a period of development and exploration, and a reliable and stable public chain still needs time to prove.

The public chain, also known as the "public chain", refers to the blockchain where anyone in the world can enter the system at any time to read data, send confirmable transactions, and compete for accounting. Public blockchains are often considered to be "fully decentralized" because no person or institution can control or tamper with the reading and writing of data in them. In terms of application, the blockchain public chain mainly includes Bitcoin, Ethereum, Hyperledger, most altcoins and smart contracts, of which the ancestor of the blockchain public chain is the Bitcoin blockchain, which has the following characteristics:

1. Open source.

2. Complete decentralization.

Anyone can become a node, every node is public, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Transactions can be read and sent by anyone, and transactions can be validly confirmed on the blockchain, allowing anyone to participate in the consensus process. The consensus process determines what a block can be added to the blockchain, as well as the exact current state.

Everyone can be financially rewarded for their contribution to the consensus process. These public chains are often considered "fully decentralized".

3. Develop decentralized applications.

Through this public chain, program developers can easily develop centralized applications. Public blockchains can protect users' rights and interests from the influence of program developers.

Blockchains include public blockchains, joint (industry) blockchains, and private blockchains. Public chain point-to-peer electronic cash system: Bitcoin, smart contracts, and decentralized application platform: Ethereum.

Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain (blockchain), an important concept of Bitcoin, is essentially a decentralized database, and as the underlying technology of Bitcoin, it is a string of data blocks associated with cryptographic methods, each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

The public chain is a kind of encryption algorithm, the blockchain is attached to the public chain, and the generation of digital currency in the blockchain must rely on the encryption algorithm of the public chain.

Blockchain originated from Bitcoin, and on November 1, 2008, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System" [2], which elaborated on the architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., which marked the birth of Bitcoin. Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born.

A few days later, on January 9, 2009, a block with a sequence number 1 appeared, and was connected with the genesis block with a sequence number 0 to form a chain, marking the birth of the blockchain [5] .

I don't know, I'll tell you when I do.

The public chain that leads the next wave — Algo Cipher

First, the market is in urgent need of a breaker.

3. Algo Chopper's journey is a sea of stars.

At present, the public chain market is extremely huge, on the one hand, there are old public chains such as Ethereum and EOS; On the other hand, there are conflux, yeeco, nervos and other public chains that have risen one after another, and the entire market is extremely huge.

At present, public chain projects are blooming everywhere, everywhere, Bitcoin, Ethereum, Conflux, etc.

As for the new generation of public chains, I am currently optimistic about the projects of Conflux, Tsinghua Yao Ban team, Academician Yao Qizhi as the chief scientist, and the research and development of the underlying public chain has great advantages.

What everyone can use is the public chain. (Anwang, Jingtong, Moke, Qtum) can be used by anyone who has a relationship.

What your own people use is the private chain.

The blockchain god complains.

If you say the bottom male.

Chain development is difficult.

The current "infrastructure" of the blockchain is not developed enough. A case in point is last year's Ethereum-based application CryptoKitties. This is a game application that uses blockchain to raise cats in the cloud, which was very popular as soon as it was launched, and it also directly led to the almost collapse of Ethereum.

In just a few days after CryptoKitties was launched, more than 45,000 transactions and nearly $6 million in transaction volume occurred, while Ethereum's transaction volume per second (TPS) was only 30-40, resulting in serious congestion on the Ethereum network, once again proving the impossible triangle of blockchain: decentralization, security, and efficiency.

At its core, blockchain is technology. Before the infrastructure is in place, all the flowery blockchain projects are in the air. At present, the underlying public chain of the blockchain is more prominent in Beijing's CONFLUX project, Academician Yao Qizhi as the chief scientist, from Tsinghua Yao Ban, the University of Toronto and other world-class universities of the bull technical team, without sacrificing decentralization and security, the TPS increased to 3000 times.

Just 1 week ago, the Conflux project team completed the 7-month transaction data of Ethereum in 25 minutes and 36 seconds on the test experiment on the first anniversary, which is the top level in the world.

There are currently two development modes for the development of blockchain public chains. The first is: the ether-like network.

The public chain is the underlying foundation of the blockchain world, and everything depends on the public chain. Bitcoin, Ethereum, and EOS are all public chains. However, the construction of the public chain is not as simple as imagined, Huobi, OKEx, etc. have announced that they will step into the field of public chain, but the mainnet launch is far away.

The manpower and R&D costs spent on building a public chain are immeasurable.

As one of the top ten blockchain technology developers in China, Hanquan Technology has been focusing on the research and development of new business procedures for 13 years, witnessed by thousands of users, and has a strong technical research and development team. The public chain is a substitute for centralized or quasi-centralized trust, which is completely open to the outside world, and anyone can use it at will, without the setting of permissions, and without identity authentication, not only can you participate in the trial at will, but also all the data that occurs can be viewed at will. Public chains are often considered "fully decentralized" and have three characteristics:

Protects users from developers, has a low barrier to entry, and all data is exposed by default.

In the first quarter of 2018 report, the global demand for blockchain development engineers increased by 517% in the previous year. Entering 2019, the trend of demand for blockchain system development specialists has not changed significantly. The term "blockchain system" in the labor market is still hot.
