In a decentralized network, without the intercommunication of participating nodes, the nodes can only be scattered islands. Communication is also particularly important in the social track. Only with smooth and secure information transmission can there be derived financial attributes such as social assets and asset tokenization.

According to official data from Tencent, traditional social giant WeChat had 1.359 billion monthly active users in the first quarter of 2024, with 45 billion messages sent daily.

First, let’s look at the network communication data of Layerzero and Wormhole.

It can be seen that Web3 cannot match the communication data of WeChat, and no public chain can achieve such TPS. Web3 is still in its early stages and has great room for development and potential.

Currently, social communication in Web3 still relies on traditional tools such as Twitter, Telegram, Discord, Email, WeChat, and some customized AI intelligent customer service robots. There are few protocols that support communication and chat within DApps and do a good job, and there is no cross-protocol and cross-chain social communication.

@Sending_Network wants to make an attempt and breakthrough in Web3 social communication. They not only make DApp (SendingMe: decentralized instant messaging tool), but also make the underlying infrastructure (any protocol can be integrated/built on it, and customized development can be done).

SendingNetwork (SDN) is an open, secure Web3 communication infrastructure that powers decentralized user interactions — enabling users to seamlessly chat, trade, and socialize within and between Dapps. Providing a custom and easy-to-install chat solution for Web3 games, wallets, and Dapp developers.

How to achieve decentralized social communication?

SendingNetwork provides a full-stack decentralized messaging experience consisting of a P2P messaging network, a built-in DID system, and decentralized data storage.

P2P Messaging Network Edge Network: It consists of randomly distributed edge nodes that help SendingNetwork clients relay and store messages. It optimizes the network, properly handles large-scale group chats, and solves the traditional broadcast storm problem of P2P networks.

The wallet-based DID system implements a many-to-many relationship between wallets and DIDs: users can map multiple wallets to a single DID, and a single wallet to multiple DIDs.

Multi-chain support: Supports Ethereum and EVM-compatible blockchains.

Efficient proof mechanism: helps recipients quickly verify the sender's DID identity.

Decentralized Data Storage All messages are stored locally on the device. When the user is offline, the P2P edge network caches all offline messages. The user can get these messages when they are back online. Decentralized storage such as IPFS or blockchain is provided as a data backup solution.

How to ensure the security of communications?

Three-layer secure communication mechanism

Layer 1: Compared to the traditional client-server model, all messages are forwarded by many decentralized routing nodes in the network, enhancing privacy and censorship resistance.

Layer 2: Use the most advanced key distribution protocol based on X3DH protocol and double ratchet algorithm to protect users' peer-to-peer communications, and third parties cannot intercept, eavesdrop or modify the communication content.

Layer 3: Metadata privacy is protected through a secure routing protocol, which means no one can know the user’s social relationships and historical behaviors.

Privacy is the main goal of decentralized communications.

Privacy: It means relatively lower efficiency, and encryption and decryption require more computing power and time.

On the one hand, choosing a faster routing protocol can bring users a better chat experience, but they have to pay service fees to these high-performance nodes. On the other hand, anonymous routing protocols can enhance chat privacy, but the introduction of TEE will lead to higher costs and certain performance losses. Therefore, users need to weigh different routing solutions based on their actual needs for performance and privacy.

The communication between Web3 users is actually the communication between wallet addresses controlled by users. Therefore, I think that integrating SendingNetwork in existing wallets is a feasible solution to achieve large-scale social adoption in the short term.

By transforming the relationship between addresses and users, and between addresses and addresses, into the relationship between people, social financial activities within a single/multiple addresses can be viewed, fed back, and executed through the wallet.

The official Sending Network also mentioned this case. In addition, there are Dapp notifications, identity authentication, etc.

At present, Sending Network has achieved very good results, which will be of great help to the subsequent Web3 protocol integration.

The team has extensive entrepreneurial experience and has successful experience in products with more than 200 million users.

Joeyz Yu: Co-founder and CEO, he has over 18 years of experience in product design and development and is a serial entrepreneur. He co-founded MoboTab in 2010 and led the development of Dolphin Browser, which has over 200 million users in the United States, Europe, and Japan. In 2014, MoboTab was acquired by Changyou.

Mason: Founder, he is a successful technology entrepreneur and venture capitalist, and has co-founded companies such as Dolphin Browser.

Jameel Lee: Co-founder, previously worked in software development at Microsoft and was involved in the development of Microsoft OS systems for Windows and Surface projects. He led the development of Dolphin Browser at MoboTap.

Sending Labs completed a $20 million seed round of financing in October last year, with support from well-known investors including Balaji (former CTO of Coinbase), Network State, Erick (former head of Binance Research Institute), Nomad Capital, Gabby, YGG, SWC Global, Symbolic Capital, Galxe, Insignia Ventures, Mindworks Capital, etc.

The track where Sending Network is located is an important part of the current Web3 communication, connecting the addresses of different users and multi-chain diversified protocols, making communication unimpeded and making the Web3 ecosystem more complete and closer.

Social interaction is an eternal need of human beings. Traditional social finance starts with social interaction and then gradually adds financial attributes. Web3 is just the opposite. It first realizes decentralized finance, binds addresses and DID identities through DID, and then realizes social functions: large-scale communication interactions between addresses.

When imagining the bright future of Web3 social communication, some problems also emerge, such as wallet-to-wallet messaging, which will bring many problems brought by decentralization: network security (nodes, centralization), protocol security (protocol permissions on user information and assets), information security (fraud, advertising, and spam). Some of these problems may seem premature now, but once decentralized communication is widely used, this problem will become increasingly prominent.

The security of information, protocols, networks, etc. is the top priority of Web3 and has existed since the birth of Web3.

Thanks to the achievements of Sending Network's current users and partners, and relying on the team's rich qualifications and strong financing background, Sending Network, as the underlying communication network, will promote the large-scale adoption of Web3 on the basis of security and efficiency.
