WarRin Protocol: A point-to-point anonymous privacy communication system
Dr.WarRin
Summary
This white paper provides an explanation of the WarRin protocol and related blockchain, point-to-point, network value, transport protocol, and encryption algorithms. The limited space will highlight the WRC allocation scheme and purpose of the WarRin Protocol Token, which is important for achieving the WRC’s stated objectives. This white paper is for informational purposes only and is not a promise of final implementation details. Some details may change during the development and testing phases.
1. Introduction
Traditional centralized communication systems such as WeChat,WhatsApp, FacebookMessage,Google Allo,Skype face a range of problems, including government surveillance, privacy breaches, and inadequate security, and the WarRin protocol proposes apoint-to-pointencrypted communications system that leveragesblockchain technology, combined with Double Ratc het algorithms, pre-keys, and extended X3DH handshakes. The WarRin Protocol uses The Generalized Directional Acyclic Graph and Curve25519,AES-256, and HMAC-SHA256 as the pronamor, allowing each account to have its own unique account chain, providing unlimited instant communication between points and unlimited scalability, anonymity, integrity, consistency, and asynchronousness.
2. WarRin Protocol communication system
2.1 Two types of communication
The Waring Protocol communication system divides chat channels into two types.
Two modes of communication
- General Chat mode: Using point-to-point encrypted communication, the service side has access to the key and can log in via multiple devices.
- Secret Chat mode: Encrypted communication using point-to-point can only be accessed through two specific devices.
The design combines some of the advantages of raiBlocks multi-chain construction with IOTA/Byteball DAG, which we call the Waring protocol. With improvements, we have given the WarRin protocol greater throughput and faster processing power while ensuring the security of the ledger, and network nodes can store the ledger in less space and search their communications accounts quickly in the ledger. When two users communicate, third parties contain content that neither manager can access. When a user is chatting in secret, the message contains multimedia that can be designated as a self-destruct message, and when the message is read by the user, the message is automatically destroyed within the specified time. Once the message expires, it disappears on the user’s device.
2.2 How chat history is encrypted
2.2.1 MTProto Transport Protocol
MTProto transport protocol
The WarRin communication system draws on RaiBlocks’ multi-chain structure for point-to-point communication. Each account has its own chain that records the sending and receiving behavior of the account. For example, in Figure 1, there are 7 accounts, each with 7 chain records of the account sending and receiving communications. On the graph, horizontal coordinates represent the timeline, and portrait coordinates represent the index of the account.
Transferring information from one account to another requires two transactions: one to send a communication from the sender’s transfer content, and one to receive information to add that content to the content of the receiving account. Whether in a send-side account or a receiving account, a PoW proof of work with the previous communication content Hash is required to add new communications to the account. In the account chain, poWwork proves to be an anti-spam communication tool that can be done in seconds. In a single account chain, the Hash field of the previous block is known to pre-generate the PoW required for subsequent blocks. Therefore, as long as the time between the two communications is greater than the time required to generate the PoW, the user’s transaction will be completed instantaneously.
In such a design, only the receiving end of the communication is required for settlement. The receiving end places the received communication signature on the account chain, which is called accepted communication. Once accepted, the receiving end then broadcasts the communication to the ledger of the other nodes. However, there may be situations where the receiving end is not online or is subject to a DoS attack, which prevents the receiving end from putting the receiving side communication on the account chain, which we call uncommoted transactions. The X symbol in Figure 1 represents an open transaction sent from Account 2 to Account 5.
Obviously, because only the sending and receiving sides of the communication are required to settle, such communication is very lightweight, all traffic can be transmitted in a UDP package and processed very quickly. At the same time, all communications in an account are kept in one chain, with great integrity, and the ledger can be trimmed to a minimum. Some nodes are not interested in spending resources to store the full communication history of the account; They are only interested in the current communications for each account. When an account communicates, its accumulated information is encoded, and these nodes only need to keep track of the latest blocks so that historical data can be discarded while maintaining correctness. Such communication is only possible if the sending and receiving sides trust each other and are not the final settlement of the entire network consensus. There is a security risk in the absence of trust on the sending and receiving ends, or in situations where the receiving end is attacked by DoS without the sender’s knowledge.
We have observed that although each account has a separate chain, the entire ledger can be expressed in the form of a WarRin object. As shown in Figure 2, this is represented by the WarRin astros trading on all accounts in Figure 1.
The first unit in the WarRin object is the Genesis unit, the next six cells represent the allocation of the initial token, and the other units correspond to the communication transactions between the account chains. We use the symbol a/b to represent a communication transaction, where the sender is a andthe recipient is b. The last 4/1 unit in Figure 2 is the last communication corresponding to Figure 1 – sending communication from account 4 to account 1. A transaction in Figure 1 is a confirmation of the latest block or the latest communication on the account chains of both parties to the communication, reflected in Figure 2 as a reference to the latest units of the account chains of both parties to the communication. Take unit 4/1, for example, where the latest block on account 4 was the receiving block for 2/4 trades and the newest block on account 1 was the send block for 1/5 trade. So on the DAG, the 4/1 cell refers to the 2/4 cell and the 1/5 cell.
The WarRin protocol uses triangular shrapned storage technology to crack impossible triangles in the blockchain through the shrapghine technology, with extensive node engagement and decontalination while maintaining high throughput and security:
- Complete shraping of blockchain status;
- Secure and low-cost cross-synth trading;
- Completely random witness selection;
- Flexible and efficient configuration
Complete decentralization ensures absolute security and scalability of the standard chain.

3. Incentives
On the basis of the WarRin agreement, by adding the incentive layer, we can effectively avoid the whole network being attacked and eliminate spam. As long as honest nodes control most of the calculations, for an attacker, the network is robust because of its simplicity of structure, and nodes need little coordination to work at the same time. They do not need to be authenticated because information is not sent to a location.

Press Release
CMS: Class 1 Innovative Drug Silevimig Injection Approved in China, Becoming the World’s First Bispecific Antibody for Passive Immunization Against Rabies
SHENZHEN, CHINA – China Medical System Holdings Limited (867.HK/8A8.SG) (“CMS”, or the “Group”) is pleased to announce that, the New Drug Application for Silevimig Injection (GR1801, the “Product”), a Class 1 therapeutic biological product has been approved by the National Medical Products Administration of the People’s Republic of China (“NMPA”) and the drug registration certificate was obtained on 22 June 2026. The Product is indicated for passive immunization in adults following rabies virus exposure.
Silevimig Injection is the world’s first fully human bispecific antibody targeting dual epitopes of the rabies virus (“RABV”), which is consistent with the recommendations of the World Health Organization (“WHO”) for a “cocktail” therapeutic paradigm. It demonstrates broad neutralization, which can effectively neutralize different viral strains or genotypes of RABV, providing immediate protection. Moreover, it is the passive immunization product with the smallest dose for rabies, resulting in less injection volume and easier administration, which can effectively reduce patient pain and improve compliance. In addition, the Product can be manufactured at scale with standardized processes and controlled production cost, and also carries no risks of blood-borne infections, low immunogenicity, and minimal interference with vaccine-induced active immunization. The market for rabies passive immunization is substantial, yet existing passive immunization products are constrained by low market penetration and limitations in safety and accessibility. The approval of the Product will provide a new treatment option for patients requiring urgent post-exposure management against rabies in China.
The approval of Silevimig Injection expands the Group’s commercialized innovative drug portfolio to 8 products, with 6 more innovative drugs under marketing review and approximately 20 projects advancing clinical development, further strengthening a tiered innovation pipeline. As of now, CMS’s innovation transformation strategy has fully entered the value-harvesting phase. Leveraging the Group’s existing expert network and market resources, the commercialization rollout of Silevimig Injection is expected to proceed steadily providing sustained momentum to the Group’s performance growth.
About Rabies
Rabies is an acute zoonotic disease caused by RABV, clinically characterized by aerophobia, hydrophobia, pharyngeal muscle spasms, and progressive paralysis[1], with a case-fatality rate approaching 100%. At present, there is no proven treatment for rabies once clinical symptoms appear. Standardized post-exposure management, comprising wound care, vaccination, and passive immunization administered as needed, remains the most effective strategy[2]. As vaccine-induced antibodies require 1-2 weeks after the first dose of vaccine injection to reach protective levels, passive immunization provides immediate coverage[1]. According to the National Technical Guidelines for the Rabies Exposure Prophylaxis (2023 Edition), patients with Category III exposure and those with Category II exposure involving severe immunodeficiency should receive passive immunization at the same time as the first dose of rabies vaccine[3]. In China, more than 40 million people are exposed to rabies annually, of whom approximately 40% fall under Category III exposure[1]. However, due to factors such as limited awareness, high cost, and restricted accessibility, only about 15% of Category III cases receive passive immunization[1]. Currently, the primary approved passive immunization option in China is human rabies immune globulin (“HRIG”). However, HRIG must be sourced from healthy donors, making it difficult and costly to obtain. Furthermore, it carries potential risks of blood-borne infections. This has led to a low penetration rate of passive immunization products in China.
More information about Silevimig Injection
Silevimig Injection is a recombinant, fully human bispecific antibody against rabies virus. It targets the viral envelope glycoprotein (G protein) of RABV and blocks its interaction with host receptors by binding to epitopes I and III. Through this mechanism, Silevimig Injection specifically neutralizes the RABV prior to the establishment of full protection by active rabies vaccination.
In a Phase III clinical trial in adults, the Product met its primary efficacy endpoint, demonstrating non-inferior protective efficacy compared with HRIG, the currently most used passive immunization product in China. The study confirmed that the Product provides immediate protection during the early stages of rabies virus exposure without compromising the active immune response induced by vaccination. In addition, a Phase III clinical trial in children and adolescents aged 2 to <18 years is currently ongoing in China. The Product has been granted a patent in China.
In September 2025, the Group through subsidiaries of the Company entered into an Exclusive Collaboration Agreement (the “Agreement”) with Chongqing Genrix Biopharmaceutical Co., Ltd.. In accordance with the Agreement, the Group has obtained exclusive commercialization rights for the Product in mainland China and exclusive licensing rights for the rest of the Asia-Pacific region, the Middle East and North Africa. The collaboration term extends until ten years after the Product receives the marketing approval in Mainland China (the “Initial Term for the Product”). Unless terminated or dissolved under the terms set forth in the Agreement, the Agreement will automatically renew for successive ten-year periods upon expiration of the Initial Term for the Product.

Sui News: Cumberland, Fluid, and SwissBorg Join Institutional Coalition on Hashi Ahead of July Global Testnet
Grand Cayman, Cayman Islands, June 23rd, 2026, Chainwire
Sui aims to transition more of Bitcoin’s $1.2T market cap into verifiable, productive onchain products.
Hashi, Sui’s native bitcoin finance primitive, gains more institutional support ahead of the scheduled launch of its global testnet this July.
Sui, where money moves as freely as messages, announced today that Cumberland, Fluid, and SwissBorg have joined the Hashi ecosystem, Sui’s native bitcoin finance primitive, weeks ahead of its scheduled global testnet launch this July. The expanding coalition addresses a critical bottleneck in crypto: solving the persistent capital inefficiency by unlocking over a trillion dollars of immobile BTC into DeFi safely.
Previous market cycles demonstrated the systemic dangers of relying on opaque, centralized credit intermediaries such as Celsius, Voyager, and Genesis to generate utility from dormant assets. Hashi replaces centralized balance-sheet trust with verifiable smart contract logic.
But with a strict separation for safety by design, Bitcoin remains securely on the native Bitcoin blockchain. Sui smart contracts handle the cryptographic and programmatic rights to enable its use as financial collateral.
“Hashi was built to unlock the productive use of Bitcoin at a scale the industry hasn’t seen before,” Adeniyi Abiodun, Co-Founder and Chief Product Officer of Mysten Labs, the original contributor to Sui. “We believe Bitcoin will become one of the largest sources of collateral in finance as the world moves onchain, and Hashi provides the foundation to make that possible on Sui.”
Built for Institutional Bitcoin Finance
Hashi is a foundational primitive setting a new standard for how builders can create bespoke, Bitcoin-backed financial products with risk parameters and loan terms that are fully verifiable onchain. In just a few weeks’ time, institutions, custodians, wallet providers, and developers can begin freely testing the infrastructure that will support Bitcoin-backed lending, borrowing, and credit origination on Sui.
Expanded Institutional Support
Three new powerhouses join the growing Hashi ecosystem, broadening support for institutional liquidity providers, market makers, and digital asset platforms:
- Cumberland: One of the digital asset industry’s largest institutional market makers, Cumberland joins the Hashi ecosystem to evaluate the protocol’s structural frameworks and prepare for eventual onchain liquidity provisioning.
- SwissBorg: A European wealth management app with over one million users, is exploring opportunities to connect its network of European high-net-worth Bitcoin holders and liquidity providers to Hashi, creating new pathways for Bitcoin-backed borrowing and lending.
- Fluid: A major DeFi lending protocol with a strong record of efficient, safe trades, is now building in preparation for mainnet institutional services. Fluid’s participation would provide institutional-grade lending markets and deepen access to Bitcoin-backed credit on Sui.
These new builders join an industry-leading group of infrastructure providers, custodians, and DeFi protocols already working together to build a native Bitcoin financial ecosystem on Sui.
“Bitcoin is the world’s most liquid digital asset, but without native utility, it remains an off-chain asset,” said Paul Kremsky, Global Head of Business Development at Cumberland. “Hashi is exciting because it introduces a transparent, institutional-grade framework for BTC-backed credit that will replace synthetic workarounds with a product we are excited to use ourselves.”
“Our community has consistently sought native ways to lend and borrow against their Bitcoin,” said Cyrus Fazel, Founder & CEO at SwissBorg. “We’re thrilled to see Hashi delivering innovative solutions that make this a reality.”
“The next phase of the industry’s growth will come from bringing larger pools of capital onchain through infrastructure institutions can actually trust,” said Samyak Jain, Co-Founder & CEO at Fluid. “Hashi gets this right: Bitcoin stays on its native chain while verifiable contracts make it productive as collateral. Fluid’s lending infrastructure is built to turn that into deep, capital-efficient Bitcoin-backed credit markets on Sui.”
These additions expand the growing consensus of many partners announced earlier this year that Sui is where Bitcoin finance will take flight, thanks to Hashi:
Custody & Wallet Access
- BitGo: Institutional custody clients.
- Blockdaemon, Cobo, Fordefi (by Paxos): Institutional wallet and infrastructure providers.
- Cubist: Cross-chain collateral infrastructure and transfer engine.
- Ledger: Retail/institutional self-custody.
- SwissBorg: UHNW European retail/institutional asset management and wallet interface.
Lending, Trading & Liquidity Providers
- Bullish: Institutional digital asset platform supplying liquidity.
- Cumberland: Leading institutional crypto market maker and liquidity provider.
- Erebor: OCC-chartered bank providing liquidity.
- FalconX: Institutional prime brokerage supplying liquidity.
DeFi & Lending Applications
- AlphaLend, Bluefin, Current, Scallop, Suilend: Native DeFi protocols enabling retail lending and borrowing on day one.
- Fluid: Connecting lending, borrowing, liquidity and more financial products into a capital-efficient system.
- Navi: One of Sui’s largest and longest running DeFi protocols slated for Hashi lending.
Vaults & Asset Management
- Concrete by Blueprint Finance: Yield-infrastructure vault platform.
- Inveniam Capital: Real-World Asset (RWA) yield strategies.
- Wave Digital Assets LLC: SEC-registered investment adviser working with industry partners to facilitate the issuance of Bitcoin-collateralized bonds.
Index Oracle, Insurance & Security Auditing
- CF Benchmarks: Crypto index provider distributing pricing data via oracles.
- Soter Insure: Native, Bitcoin-denominated institutional insurance.
- Asymptotic, Certora, OtterSec: Smart contract security and formal verification auditors.
The activation of the global testnet this July represents the ultimate rehearsal for fully changing Bitcoin Finance. This sandbox environment is designed for institutional engineers, Sui protocols and developers, and custody partners to test integration parameters, stress-test the code under simulated market volatility, and verify cryptographic integrity ahead of mainnet release.
