SAFE is a decentralized blockchain security payment and privacy computing platform launched by the Singapore SAFE Foundation in October 2014, focusing on the privacy protection of digital assets. As of July 2021, it has a history of 7 years. During this period, it has experienced three major versions of Anwang 1.0, Anwang 2.0, and Anwang 3.0, and has made many beneficial achievements in various innovative technologies and commercial applications. exploration. Annet 4.0 brings years of practical experience and achievements in the industry, based on cryptography theory and privacy computing, oriented by technological innovation and application innovation, focusing on privacy protection, strengthening secure payment, optimizing asset privacy, and introducing cross-chain assets and stable coins , create a safeswap trading field, expand more commercial applications, and aim to build a global privacy protection ecosystem.

1. Project introduction

Safe Network Space 3 (SAFE) combines the advantages of DASH, integrates Safe Network Space 2 (DNC2) and Voting Chain (ELT), successively introduces Sapp application development protocol and security smart contract, and extends Safe Payment (instant payment) Payment, secure payment), Anzi (asset issuance and management, issuing tokens based on Anwang 3), Antou (secure voting, the original voting chain) and other three application directions, aiming to become the world's largest and safest digital currency The payment and application development platform, combined with the blockchain middleware and digital currency payment platform, greatly simplifies the implementation of the "blockchain +" strategy for enterprises and institutions, from token issuance and payment implementation, application development, privacy protection, and blockchain voting and other dimensions to build tens of millions of users and community ecology.

Application scenario

The Anwang team will build a good application development platform, and build a huge Anwang ecosystem around the three application directions of Anfu, Anzi, and Antou, combined with third-party applications.

Annet intends to simplify the blockchain application development process and provide a series of application development services. Small and medium-sized enterprises that conduct application development and digital asset issuance on the Internet to gain user trust. They only need to determine the blockchain application scenarios, issue digital assets, and focus on the docking and application of digital assets and existing businesses.

Annet can provide a complete set of blockchain application consulting, technical support, assistance or outsourcing development, and token real application landing services, which will bring profits to the team.

Safe Payment:
When the number of Anwang users is increasing, SAFE becomes a common certificate in Anwang business district, and Anwang users are willing to use SAFE to purchase commodities and service, Anwang merchants are willing to accept SAFE payment from customers, and the payment function of SAFE is reflected.

Anpay is the infrastructure of Annet, Anzi, Antou and other applications will use the Anfu interface. Anpay needs to open up a channel for all products and services provided by Annet’s partners to use SAFE and other assets issued on Annet for payment; secondly, it is to open up channels for purchasing Annet’s partners based on other tokens issued by Annet. Access to goods and services.

The biggest feature of Anfu is instant payment and privacy payment. The speed of instant payment is comparable to the existing third-party payment, which solves the problem of slow confirmation of Bitcoin; the feature of privacy payment is to hide the real identity of the sender or receiver. address, protecting personal privacy. Anpay has added several privacy payment modes on the basis of DASH

Such as: transfer notes, ring signature sending, invisible collection, hidden amount, etc., so that users have more choices for privacy protection.

Security Assets:
Valuable and transferable electronic data are called digital assets. Anzi, a digital asset management system based on Annet, can provide complete digital asset issuance, additional issuance, transfer and destruction functions, and users can combine many application scenarios by themselves. Among them are original digital assets, such as cryptocurrencies, points, point cards, prepaid cards, game equipment, stocks and equity, etc.; physical assets can also be digitized and issued and transferred in security assets, such as legal currency, real estate and land, furniture, various Such documents, but only if there is an acceptance institution.

Many users brought by each digital asset issuer will become Safenet users and holders of SAFE, which is conducive to the establishment of a huge Safenet ecosystem.

Antou:
Antou is the voting chain, the name of the function after the voting chain is translated to Anwang 3. Antou aims to research and develop a blockchain dedicated to voting, elections and lotteries that can support the US presidential election, and supports entertainment applications such as voting donations, voting quizzes, campaign speeches and live broadcasts, and campaign games. In Antou, each voter votes in real name or privately according to his or her own wishes with a real or virtual identity, and can verify whether the final result contains his or her vote. Antou uses technical means to solve the disadvantages of paper ballots, electronic voting, and online voting, making elections, decision-making, and public opinion surveys more open and transparent, preventing voting results from being interfered by external forces, and making voting more credible.

Technical Overview

Annet is positioned as a payment platform and application development platform that focuses on application security and privacy protection. Annet's underlying platform includes the underlying protocol and application interface layer. The underlying protocol includes consensus algorithms, cryptography, P2P protocols, master node networks, and budget systems inherited from DASH; in addition, Annet's unique Application development agreement, Anzi agreement, candy agreement, smart contract and Anpay expansion function, etc.

Consensus Algorithm:
Annet’s mining algorithm is inherited from DASH without modification.

(1) Use POW workload proof mining, X11 hash algorithm, and use 11 specific Hash functions (blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd, echo);
(2) Mining can be CPU/GPU/ASIC, and the current mining machines are mainly ASIC mining machines; Proposer;

Cryptographic Algorithms:
Cryptographic algorithms are inherited from DASH and Bitcoin, and will also inherit some cryptographic algorithms from Annet 2, and will also introduce some new encryption algorithms, mainly involving:
Merkle-Tree, Annet uses Merkle-Tree to generate the root of all transaction IDs in the block for data integrity verification;
Elliptic Curve Cryptography (ECC) algorithm, Annet uses the ECC algorithm of the secp256k1 curve Sign the transaction as a signature algorithm;
Hash algorithm: Annet adopts blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd, echo and other hash algorithms for mining;
·Ring signature payment: Anfu intends to use the ring signature algorithm for payment in order to hide the sender;
·Invisible collection: Anfu intends to use stealth address technology for stealth collection in order to hide the recipient;
· Homomorphic technology: Anfu intends to use homomorphic encryption technology to encrypt and hide the amount;

Master node network:
The master node network is the most important infrastructure of DASH, and it is also inherited by Anwang. The establishment of a master node needs to mortgage 1,000 SAFE to get 45% of the mining income of the entire network. DASH has been online for 4 years, and the number of master nodes is 4,700. The security network has been online for two months. By March 25, there were 1,900 master nodes. node.

Budget system:
The budget system is a very distinctive community governance structure inherited from DASH. 10% (7,000 SAFE per month) of Annet’s mining revenue for each block is not generated, but will be generated through “super blocks” at the end of the month.

During the entire month, anyone can submit a budget application to Annet, which is decided by the vote of the masternode users. As long as any proposal is approved by at least 10% of the network masternodes, a series of "super blocks" will be created by the end of the month , to pay SAFE to approved proposals to fund promotion projects or research and development projects that are helpful to the development of the Anwang community.

Application Development Protocol:
Annet provides a set of standard protocols for developing blockchain applications based on Annet, which is the first step in becoming an application development platform. The design purpose of the application development protocol: to make it very easy for enterprises and institutions that want to implement the "blockchain +" strategy to develop blockchain applications. Anfu's extended functions, Anzi, and Antou are examples of applications in the Annet application development protocol. Based on the application developed by Annet, we call it Safeapp, or Sapp for short.

Security Agreement:
Valuable and transferable data are called assets, such as points, digital currency, documents, credit information, insurance, loans, digital renminbi, etc. Anzi Protocol, that is, Annet Asset Management Protocol, provides various operations such as digital asset issuance, additional issuance, transfer, destruction, candy distribution, candy collection, and query. Developers can combine many application scenarios by themselves, such as digital currency Issuance and transfer; bill of lading issuance, transfer and destruction; even points and digital renminbi points can be issued at the same time, and exchanged at a certain exchange rate, etc.

Annet only provides a platform for asset issuance, and does not endorse or review the assets issued. The asset issuer only needs to burn 500SAFE (decreasing according to time, at least 50SAFE), the asset name is not duplicated, and the digital asset can be issued with a few clicks. Anwang wallet, blockchain browser, exchange interface, and payment interface will all be automatically supported, greatly reducing the developer's digital asset issuance cost and time.

Assets on Annet are uniformly received and sent using Annet addresses, which require transaction fees denominated in SAFE. The Anwang team will also open SAFE trading zones on multiple exchanges, and the tokens on Anwang will form trading pairs with SAFE to facilitate the establishment of Anwang's ecology.

Candy agreement:
The candy agreement is a very distinctive agreement in the Anzi agreement. The main idea is: when issuing tokens through the SAFE agreement, the token issuer needs to distribute 0.1%~10% of the newly issued tokens to the holders of SAFE SAFE, and the specific ratio is specified by the token issuer.

Smart contracts:
Smart contracts are currently facing greater security risks, so Annet does not use smart contracts as the first application, but uses various protocols to safely meet the needs of application development. More complex applications may use smart contracts, so Anwang will also introduce smart contracts later.

The current technical route is to transplant the Ethereum EVM to Annet. The Ethereum smart contract is widely used in the free community, so it needs to be supported first. There have been some cases of EVM transplantation on Bitcoin-like blockchains. Annet will refer to these technical routes and its own understanding of smart contract security to formulate some smart contract security rules and permission access systems to form a unique smart contract. Contract virtual machine SVM.

Anpay Expansion:
At present, the bottom layer of DASH has provided the functions of real-time payment and private sending, and Anpay will further expand.

P2P protocol:
Annet's P2P protocol continues to use the Bitcoin P2P protocol framework, and some extensions have been made on this basis to meet the needs of subsequent instant messaging and decentralized storage. The technical plan will be announced separately .

Two. Comment

SAFE 3 (SAFE) is a fork from Dash (DASH), so it has all the excellent functions of DASH, and at the same time integrates DNC2 (DNC2) and voting chain (ELT), the introduction of smart contracts, extended security payment: secure payment and real-time payment, combined with the payment characteristics of DASH, expanded more anonymous payment functions, and moved towards more efficient real-time payment and privacy payment that protects user transactions from being untraceable develop. Security capital: Realize the functions of issuing, transferring, destroying, dividends and so on of digital assets. Anchat: It mainly conducts encrypted and decentralized chats to prevent information and IP leaks and protect the security of message senders. Antou: Voters need to consume tokens during elections, decision-making, and investigations. At the same time, it also supports four application directions such as live broadcast rewards, quiz, evaluation and other voting scenarios, aiming to become the world's largest, safest, and most private digital Currency payment and application platform.
