Anwang (SAFE): A Decentralized, Privacy-Focused Blockchain Platform

Introduction

Launched in October 2014 by the Singapore SAFE Foundation, Anwang (SAFE) is a decentralized blockchain platform focused on secure digital asset payments and privacy-preserving computation. Over its seven years of existence (as of July 2021), Anwang has undergone three major iterations (Anwang 1.0, 2.0, and 3.0), exploring various innovative technologies and commercial applications.

Anwang 4.0 leverages years of industry experience and achievements, building upon cryptography and privacy computing. Guided by technological and application innovation, it prioritizes:

• Privacy protection

• Enhanced secure payments

• Optimized asset privacy

• Integration of cross-chain assets and stablecoins

• Development of the Safeswap trading platform

• Expansion of commercial applications

Ultimately, Anwang aims to build a global privacy protection ecosystem.

Project Overview

Anwang 3 (SAFE) combines the advantages of DASH with features from Anwang 2 (DNC2) and Voting Chain (ELT). It introduces the Sapp application development protocol and secure smart contracts, extending into three main application areas:

• Anfu (Anpay): Instant and secure payments.

• Anzi (Anasset): Asset issuance and management, with tokens issued on Anwang 3.

• Antou (Anvote): Secure voting, originating from Voting Chain.

Anwang aspires to be the world's largest and most secure digital currency payment and application development platform. By collaborating with blockchain middleware and digital currency payment platforms, it aims to simplify the implementation of "Blockchain+" strategies for enterprises. This will be achieved through:

• Token issuance and payment implementation

• Application development

• Privacy protection

• Blockchain voting

The goal is to build a community ecosystem with tens of millions of users.

Application Scenarios

The Anwang team is committed to building a robust application development platform. Centering around the three application areas of Anfu, Anzi, and Antou, and incorporating third-party applications, Anwang seeks to construct a vast ecosystem.

Anwang aims to simplify the blockchain application development process and provide a range of development services. The target users are small and medium-sized enterprises that:

• Lack understanding of the blockchain industry

• Face difficulties in blockchain technology research and development

• Want to develop applications and issue digital assets on the blockchain to gain user trust

These enterprises can simply define their blockchain application scenarios, issue digital assets, and focus on integrating their existing businesses with these assets.

Anwang can provide a complete suite of services including:

• Blockchain application consulting

• Technical support

• Development assistance or outsourcing

• Token application implementation

These services will generate revenue for the team.

Anfu (Anpay)

As the number of Anwang users grows, SAFE will become a common currency within the Anwang ecosystem. Anwang users will be willing to use SAFE to purchase goods and services from Anwang partners, and Anwang merchants will be willing to accept SAFE payments. This will establish SAFE's payment functionality.

Anfu, the foundational infrastructure of Anwang, will be used by Anzi, Antou, and other applications. It aims to achieve two key goals:

1. Enable the use of SAFE and other Anwang-issued assets for payments across all goods and services offered by Anwang partners.

2. Enable the purchase of goods and services from Anwang partners using other Anwang-issued tokens.

The key features of Anfu are:

• Instant payments: Comparable to existing third-party payment systems, addressing the slow confirmation times of Bitcoin.

• Privacy payments: Hide the true addresses of senders and receivers, protecting personal privacy.

Building on DASH, Anfu introduces several privacy payment modes:

• Transaction memos: Allow for private communication between sender and receiver.

• Ring signature sending: Obscures the identity of the sender.

• Stealth addresses: Enable the receiver to receive payments without revealing their address.

• Amount hiding: Masks the transaction amount from public view.

These features provide users with more privacy protection options.

Anzi (Anasset)

Anzi is a digital asset management system built on Anwang, facilitating the issuance, additional issuance, transfer, and destruction of digital assets. Users can customize various application scenarios.

Anzi supports both:

• Natively digital assets: Cryptocurrencies, loyalty points, prepaid cards, game items, stocks, and equity.

• Digitized physical assets: Fiat currencies, real estate, furniture, and various documents. This requires the involvement of redemption institutions.

Each digital asset issuer brings a user base to Anwang, potentially expanding the Anwang ecosystem and increasing SAFE adoption.

Antou (Anvote)

Antou is the Voting Chain platform integrated into Anwang 3. Its goal is to develop a blockchain specifically for voting, elections, and lotteries, capable of supporting large-scale events like the US presidential election.

Features of Antou include:

• Support for voting donations, betting on elections, campaign speeches and live broadcasts, and election-related games.

• Voters can participate with real or virtual identities, using either public or private voting methods.

• Verifiability of final results to ensure that each vote is counted.

Antou leverages technology to address the shortcomings of paper, electronic, and online voting. It promotes transparency and prevents external interference, making voting more trustworthy.

Technical Overview

Anwang prioritizes application security and privacy protection as a payment and application development platform. Its underlying platform comprises two layers:

1. Underlying protocol layer: Inherited from DASH, this layer includes consensus algorithms, cryptography, P2P protocol, masternode network, and budget system.

2. Application interface layer: This layer includes Anwang's unique application development protocol, Anzi protocol, Candy protocol, smart contracts, and Anfu extensions.

Consensus Algorithm: Anwang inherits DASH's Proof of Work (POW) mining algorithm with X11 hashing (using 11 specific hash functions) and a block reward distribution of 45% to miners, 45% to masternodes, and 10% to proposal submitters.

Cryptography: Anwang inherits cryptographic algorithms from DASH and Bitcoin while introducing new ones, including Merkle-Tree for data integrity checks, ECC (secp256k1 curve) for transaction signatures, various hash functions for mining, ring signatures for anonymous sending, stealth addresses for anonymous receiving, and homomorphic encryption for hiding transaction amounts.

Masternode Network: Inherited from DASH, Masternodes require collateral of 1000 SAFE and receive 45% of the block rewards. Anwang boasts a rapidly growing Masternode network.

Budget System: Another feature inherited from DASH, the budget system allocates 10% of the block rewards to community-approved proposals submitted throughout the month and voted on by Masternodes.

Application Development Protocol: This protocol enables the easy development of blockchain applications (called Safeapps or Sapps) on Anwang, making it accessible for enterprises to implement blockchain solutions.

Anzi Protocol: This protocol governs the creation, issuance, transfer, destruction, and other operations related to digital assets on Anwang, supporting various use cases. Issuing assets requires a small fee and a unique asset name, and they automatically gain support from Anwang wallets, blockchain explorers, exchanges, and payment gateways.

Candy Protocol: This protocol encourages the distribution of newly issued tokens to existing SAFE holders, incentivizing the growth of the Anwang ecosystem.

Smart Contracts: While recognizing the security risks, Anwang will introduce smart contracts in the later stages. The current roadmap involves porting Ethereum Virtual Machine (EVM) with added security measures and a permissioned access system, forming the Anwang Smart Contract Virtual Machine (SVM).

Anfu Extensions: Building on DASH's instant and private payment features, Anfu will be further expanded to enhance user experience.

P2P Protocol: Anwang's P2P protocol builds on Bitcoin's framework with extensions for instant messaging and decentralized storage functionalities.

Conclusion

Anwang 3 (SAFE), a fork of DASH, inherits its strengths while integrating functionalities from Anwang 2 and Voting Chain. By incorporating smart contracts and expanding on DASH's payment features, Anwang aims to become a leading platform for secure, private, and efficient digital asset payments and application development. With its focus on privacy, user-friendliness, and a diverse ecosystem, Anwang has the potential to attract a large user base and facilitate the adoption of blockchain technology.
