❶ Horizontal comparison of various blockchain architectures

Horizontal comparison of various blockchain architectures
I often hear people talking about blockchain, since the birth of Bitcoin in 2009 So far, various blockchain systems or blockchain-based applications have been continuously developed and applied to a large number of scenarios, and the blockchain technology itself is constantly changing and improving.
Blockchain is also called a distributed ledger, which corresponds to a centralized ledger, such as a bank. Different from centralized ledgers, distributed ledgers rely on redundant storage of ledger data in all participating nodes to ensure the security of the ledger. Simply put, blockchain uses three underlying technologies: peer-to-peer network technology, cryptography technology, and distributed consensus algorithms. Usually, the blockchain system also “comes with a free feature” called a smart contract. Although smart contracts are not a necessary part of the blockchain system, due to the decentralized nature of the blockchain, it can provide a trusted computing environment for smart contracts.
In order to adapt to the needs of different scenarios, blockchain systems often need to undergo various transformations during actual application to meet specific business requirements, such as identity authentication, consensus mechanism, key management, transaction frequency, Response time, privacy protection, regulatory requirements, etc. Companies that actually apply blockchain systems often do not have the ability to carry out such transformations, so some frameworks for customizing dedicated blockchain systems have gradually appeared on the market. Using these frameworks, it is easy to customize products suitable for enterprises. Blockchain system for your own business.
This article will conduct a horizontal comparison of several typical blockchain frameworks currently on the market to see what characteristics they have and what are the differences between them. In order to keep the comparison fair, this article will only discuss open source blockchain frameworks.
A brief introduction to each blockchain architecture
1. Bitcoin
Bitcoin originated from an article named Satoshi Nakamoto published in 2008 The paper is "Bitcoin: A Peer-to-Peer Electronic Cash System", which describes an electronic currency he calls "Bitcoin" and its algorithm. In the following years, Bitcoin continued to grow and mature, and its underlying technology was gradually recognized and abstracted by people. This is blockchain technology. As the originator of blockchain, Bitcoin plays an important role in the blockchain family. The number of altcoins developed based on Bitcoin technology is as countless as the stars in the sky.
It can be learned from the paper that Satoshi Nakamoto’s purpose of designing Bitcoin is to realize an electronic cash system completely based on a peer-to-peer network, so that online payments can be directly initiated by one party and paid to another party, with an intermediate NoNeed to go through any intermediaries. In summary, he hopes that the design of Bitcoin can achieve the following goals:
● Issue currency without the need for a central authority
● Make payments without the need for intermediaries
● Maintain user trust Anonymity
● Transactions cannot be reversed
From the perspective of an electronic cash system, the above goals have been basically achieved in Bitcoin, but there are still some technical problems that need to be solved, such as scalability attacks , block capacity limit, block fork, scalability, etc.
In terms of application scenarios, a large number of digital currency projects are currently designed based on the Bitcoin architecture. In addition, there are some more practical application cases, such as colored coins, t?, etc.
Colored coins (coloredcoins), by carefully tracking the ins and outs of some specific Bitcoins, they can be distinguished from other Bitcoins. These specific Bitcoins are called colored coins. They have some special properties and thus have a value that is independent of the face value of Bitcoin. Using this characteristic of colored coins, developers can create other digital assets on the Bitcoin network. Colored coins are Bitcoins themselves, require no third parties for storage and transfer, and can leverage the already existing foundation of Bitcoin.
t? is an application of Bitcoin blockchain in the financial field. It is a blockchain-based private and public equity trading platform launched by the American online retailer Overstock.
2. Ethereum
The goal of Ethereum is to provide a blockchain with a Turing-complete language. With this language, contracts can be created to write arbitrary state transition functions. Users only need to simply By implementing logic with just a few lines of code, you can create a blockchain-based application and apply it to scenarios other than currency.
The design philosophy of Ethereum is not to directly "support" any application, but the Turing-complete programming language means that in theory any contract logic and any type of application can be created. In summary, in addition to the design goals of Bitcoin, Ethereum also needs to achieve the following goals:
● Turing-complete contract language
● Built-in persistent state storage
Currently There are hundreds of contract projects based on Ethereum, the more famous ones include Augur, TheDAO, Digix, FirstBlood, etc.
Augur is a decentralized prediction market platform based on Ethereum blockchain technology. Users can use digital currency to make predictions and bets, relying on the wisdom of the crowd to predict the outcome of events, which can effectively eliminate counterparty risks and server centralization risks.
Limited by space limitations, we will not introduce more projects based on the Ethereum smart contract platform. There are many blockchain projects that have been modified based on Ethereum code, but almost all of them are closed source projects and can only be inferred based on some public features., so we will not discuss it in this article.
3. Fabric
Fabric is a blockchain framework developed by IBM and DAH, and is one of the project members of Hyperledger. It functions similarly to Ethereum and is also a distributed smart contract platform. But unlike Ethereum and Bitcoin, it is a framework from the beginning, not a public chain, and there is no built-in token.
Hyperledger is an open source project launched by the Linux Foundation in 2015 to promote blockchain technology and standards. Its members include: ABN AMRO, Accenture and more than a dozen different interests. As an entity, the goal is to allow members to work together to build an open platform to meet various user cases from multiple different industries and simplify business processes.
As a blockchain framework, Fabric adopts a loosely coupled design to modularize components such as consensus mechanism and identity verification so that they can be easily replaced with custom modules during the application process. In addition, Fabric also uses container technology to run smart contract code (chaincode) in docker, so that smart contracts can be written in almost any high-level language.
The following are some design goals of Fabric:
● Modular design, components can be replaced
● Smart contracts running on docker
There are already many developers using Fabric architecture for development During the implementation of proof-of-concept (POC) projects, there are many attempts by some financial institutions. However, because the project has just started, there is no mature application yet.
4. DNA
DNA (Distributed Networks Architecture) is a blockchain architecture developed by "Distributed Technology", a blockchain startup company headquartered in Shanghai. It can support public chains at the same time. , alliance chain, private chain and other different application types and scenarios, and quickly integrate with business systems.
Different from Ethereum and Fabric, DNA supports a variety of digital assets at the bottom of the system. Users can create their own asset types directly on the chain and use smart contracts to control its issuance logic. For most blockchain application scenarios, digital assets are indispensable, and developing a set of transfer and issuance logic based on smart contracts for each digital asset is very wasteful and inefficient. Therefore, it is very necessary for the bottom layer of the blockchain to provide direct digital asset functions. For those application scenarios that do not require digital assets at all, arbitrary custom logic can also be written based on the smart contract architecture provided by DNA.
The design goals of DNA mainly include the following points:
● Underlying support for multiple digital assets
● Turing-complete smart contracts and state persistence
● Cross-chain interoperability
● Transaction finality
Currently Many financial institutions use DNA architecture to develop blockchain proof-of-concept products. In addition, there are some blockchain projects that have been implemented, such as Xiaoyi Blockchain, Fachain, etc.
Antshares is a public chain positioned at the digitization of assets. It digitizes assets and rights in the physical world and uses a decentralized network protocol to conduct registration, issuance, transfer transactions, clearing and delivery and other financial services through a peer-to-peer network. . It adopts a community development model and is architecturally consistent with DNA, allowing cross-chain interoperability with any DNA-based blockchain system.
FaChain is the world's first large-scale commercial legal evidence storage blockchain. It is an evidence recording and preservation system based on DNA blockchain technology and is established and operated by multiple institutions. The system has no central control point, and once the data is entered, it cannot be tampered with by a single agency or node, thus meeting the requirements for judicial evidence storage.
5. Corda
Corda was developed by R3CEV, a New York-based blockchain startup. The R3 blockchain alliance initiated by it has so far attracted the participation of dozens of giant banks. These include Wells Fargo, Bank of America, Bank of New York Mellon, Citibank, Commerzbank, Deutsche Bank, HSBC, Mitsubishi UFJ Financial Group, Morgan Stanley, National Australia Bank, Royal Bank of Canada, Sweden's Nordisk Bank ( SEB), Société Générale, etc.
It can also be seen from the composition of R3 members that Corda is a blockchain architecture specifically used for bank and inter-bank business. Although R3 itself claims that Corda is not a blockchain, judging from various characteristics, it has some characteristics of a blockchain.
Technical comparison
1. Digital assets
Next, we will make a series of technical comparisons of these blockchain frameworks mentioned above, and introduce their differences from multiple dimensions. with similarities.

Blockchain’s built-in tokens are often an economic incentive model and a means to prevent spam transactions. Bitcoin is born with and has only one built-in token, so all "transactions" in the Bitcoin system are essentially transfer behaviors, unless additional digital assets are added to Bitcoin through an external protocol layer.
Ethereum and DNA have built-in tokens. In addition to the above-mentioned economic incentives and preventing spam transactions, their role is to provide a charging channel for the built-in functions of the system. For example, Ethereum's smart contract operation requires GAS, and DNA's digital asset creation also requires a certain amount of tokens.
Ethereum and Fabric are notThere is built-in support for a variety of digital assets, and corresponding functions are implemented through smart contracts. The advantage of this approach is that the system design can be very simple, and the behavior of the assets can be specified arbitrarily, with a high degree of freedom. However, such a design will also bring a series of negative impacts. For example, all asset creators have to write repeated business logic themselves, and users cannot operate their assets in a unified way.
In contrast, DNA and Corda adopt a method of supporting multiple digital assets at the bottom level, allowing asset creators to easily create their own asset types, and users can also manage all in the same client. assets. For business scenarios with more complex logic, they can also use smart contracts to enhance the functions of assets, or create a business logic that has nothing to do with assets.
2. Account system

UTXO (Unspent Transaction Output) is a mechanism: each digital currency will be registered under the ownership of an account. A digital currency has two status, that is, either it has not been spent or it has been spent. When you need to use a digital currency, mark its status as spent, create a new digital currency of the same amount, and register its ownership under a new account. In this process, the digital currency marked as spent is called the input of the transaction, and the new digital currency created is called the output of the transaction. In a transaction, it can contain multiple inputs and multiple output, but the sum of the inputs and the sum of the outputs must be equal. To calculate the balance of an account, just add the denominations of all digital currencies registered under the account.
Bitcoin and Corda adopt an account mechanism such as UTXO, while Ethereum adopts a more intuitive balance mechanism: each account has a status, and the status directly records the current balance of the account and the logic of the transfer. It means subtracting a part of the balance from one account and adding the corresponding balance to another account. The subtracted part and the added part must be equal. DNA is compatible with both modes in terms of account mechanism.
So what are the advantages and disadvantages of UTXO mode and balance mode? The biggest benefit of UTXO is that UTXO-based transactions can be verified in parallel and ordered arbitrarily, because all UTXOs are not related to each other. This is very helpful to the future scalability of the blockchain, and the balance-based design There is no such advantage; on the contrary, the advantage of balance design is that the design idea is very simple and intuitive, which facilitates program implementation. Especially in smart contracts, it is very difficult to deal with the status of UTXO. This is also the reason why Ethereum, which uses smart contracts as its main function, chooses the balance design, while Bitcoin, OnchainDNA, Corda and other digital asset-centric architectures are more inclined to UTXO design.
As for identity authentication, Bitcoin and Ethereum basically have no identity authentication design. The reason is very simple, because the design ideas of both of them emphasize privacy and anonymity and oppose supervision and centralization, and identity authentication is inevitable. Introduce some centers or weakened central institutions. Fabric, DNA and Corda all chose to use digital certificates to authenticate user identities because all three have design goals of being applied to existing financial systems, and financial systems must consider compliance and accept supervision. In addition, Existing financial systems have adopted digital certificate solutions on a large scale, so that they can be quickly integrated with blockchain systems.

❷ What is Ethereum Coin

Ethereum Coin is a token on the Ethereum blockchain. It is a digital currency and has the characteristics of decentralization. Has value and can be traded. Knowledge about these digital currencies can be learned at Crypto Finance.

❸What is EDC?

The English name of EDC coin is Blockchain, and the Chinese name is EDC Blockchain. The full text introduces the mass issuance of EDC Blockchain (EDC), including EDC Blockchain (EDC) white paper, EDC Blockchain (EDC) issuance price, etc.

EDC Blockchain is one of the first blockchain platforms for business development and tokenization, using Graphene technology to operate its network. Using Graphene allows you to conduct instant transactions on the platform with small fees and use multiple coins simultaneously.

Another feature of the EDC blockchain platform is the built-in blockchain token constructor. With this feature, users can create their own digital assets to grow and expand their business. It doesn’t matter whether you need a simple nominal token with relatively small turnover or a complex cryptocurrency with a large number of customizable parameters and whether you need to mine it using a PoS (proof-of-stake) algorithm.

EDC Blockchain Token Constructor provides a comprehensive packaged solution for any small and medium-sized enterprise! To popularize your assets and gain more liquidity, the EDC Blockchain platform offers the ability to list your tokens on the company’s partner exchanges.

❹ What does the token in the liquidity pool mean?

The token in the liquidity pool refers to the tokens generated after the liquidity provider invests in the liquidity pool and locks the funds.

Token is an encrypted virtual currency. Initial coin offerings are a derivative method of raising funds for new treaties or infrastructure. Through the entire token issuance process, the company will create and sell tokens; the tokens can be used as investments or used after the project application is launched.
There are two types of tokens: first, they are native tokens of the blockchain (Native Token) or built-in tokens (Built-in Token); second, they are issued on the blockchain and used to represent a certain ExtraspecificAsset-backed Token for all assets.

Token is a virtual account name and the virtual currency of the electronic card. Tokens play a role of representation and are just symbols. In primary schools, they are especially represented by small red flowers, five-pointed stars, etc. They can also be scorecards, points, etc., which can be used flexibly according to the situation.

❺ What is the difference between TRC20 and ERC20?

❻ How are iGS tokens issued?

iGS tokens are in BSC The total circulation of BEP-20 tokens issued on the platform is 840,000, all of which are in circulation. It is a basic tool used by the entire iGames ecosystem for transactions and interactions, and is also the only governance token in the entire platform. Its value attributes incorporate voting governance, incentive growth, value capture, and compliance with applications. It can be used to exchange assets between players or for game copyright transactions between creators, and establish a user-based reward system.

❼ What are tokens in the blockchain?

Tokens are utility tokens.
Utility tokens refer to special tokens used to purchase certain specific goods or services. Cryptocurrency. There are two main categories of tokens: utility “tokens and security” tokens.
In addition, in order to make the entire usage and payment process more automated, file tokens have a very important advantage compared to ordinary currencies, that is, users can choose to use them in units smaller than a penny, making pricing easy Extraordinarily accurate. The goal of file tokens is to make cloud storage systems as safe and reliable as other commercial activities, but at the same time decentralized. Utility tokens serve as simple tools that make this strategy more feasible.
Extended information:
Users can purchase these tokens with any currency, and hard disk space owners can also exchange the tokens they harvest into the real currency they need, or save these tokens for storage their own data.
Security Tokens
Security tokens can also be called token securities or crypto-securities, rather than just a currency. It usually represents ownership of an actual asset. Just like traditional stocks and funds, they are regulated by the SEC. Ordinary securities are on paper, while many more exist in a unified database and are monitored. Security tokens use the blockchain system, a decentralized database to monitor who owns which assets at any time.
The use of security tokens based on blockchain technology gives people the possibility of transactions outside the opening hours of ordinary banks and stock markets, and also makes transfers faster. In addition, a software-based trading venue makes contracts more flexible and automates all aspects of supervision and recording. Security tokens make it easier for users to diversify their investments. Just like an electronic trading investment account can trade many different stocks and funds; a blockchain digital wallet canTo trade different security tokens, which can represent stocks, bonds or even real estate.
Connection to Cryptocurrencies Tokens like Ethereum do not require a separate blockchain. Instead, their ownership accounting systems can be outsourced to existing blockchain ledgers, allowing for distributed accounting. This essentially creates a new distributed ledger for a specific token, such as Ethereum’s ledger. Each user's token transactions on the Ethereum network will be monitored and recorded, and they will also need to pay a small fee to authenticate the transaction. Tokens are still in the early stages of development, and there may be more innovation in how they are used in the coming years.
