Safeheron Open-Sourced Implementation of the Lindell 17 MPC Protocol in C++
Platform Updates

Safeheron Launches Open-Source Implementation of the Lindell 17 MPC Protocol in C++

Safeheron today officially announces the open-source release of a complete C++ implementation of the two-party MPC ECDSA protocol, Lindell 17. This marks another significant milestone in our commitment to “Open Source as Trust.” While various general threshold signature protocols have emerged in the MPC field in recent years, the classic Lindell 17 protocol retains high engineering value for specific application scenarios. Through this release, we aim to provide cryptography researchers and engineering developers with a clear, standardized, and auditable reference implementation. What is the Lindell 17 Protocol? The Lindell 17 protocol originates from Yehuda Lindell’s paper Fast Secure Two-Party ECDSA Signing. It is a threshold ECDSA scheme designed specifically for Two-Party Computation (2PC) scenarios. Unlike general threshold protocols (t-of-n) that must handle complex multi-party interactions, Lindell 17 is highly optimized for the 2-of-2 signing model. Its core advantages include: Therefore, in scenarios such as “Client + Server” co-signing (2-factor control), Lindell 17 remains an efficient and competitive lightweight choice. The Variant Open-Sourced by Safeheron The version open-sourced by Safeheron is a Lindell 17 protocol variant based on Additive Secret Sharing, which offers broader application value. Beyond the engineering implementation, Safeheron has provided the necessary security analysis and proofs to clearly define the protocol’s security assumptions and applicability boundaries. Why We Open Source? This release features several key characteristics: During implementation, […]

This anniversary belongs to every client and partner who has walked this path with us—it is your trust that forms the bedrock of everything we have built.

Together, we safeguard hundreds of billions of dollars in assets, a testament to our strength and determination as guardians of the ecosystem. Win-Win Collaboration: A Tribute to Our Partners […]

Hong Kong Stablecoin Market Sees Major Developments

Hong Kong stablecoin markets have seen stablecoins advancing steadily, with the total global stablecoin transaction volume surpassing US$20 trillion last year. The recent passage of the Stablecoins Ordinance introduced a licensing regime for issuers, transforming the regulatory framework for virtual assets. The development of hong kong dollar-linked stablecoins and fiat-backed stablecoins highlights the city’s focus on a secure issuance mechanism of stablecoins. Hong Kong’s evolving financial landscape now features stronger safeguards for digital currency and crypto-backed stablecoins, as the licensing regime for issuers aligns with international standards. Evidence Description Impact on Regulatory Environment Licensing regime for stablecoin issuers established Enhances investor protection and aligns with international standards Only licensed entities can offer stablecoins Mitigates risks associated with unregulated trading Public education efforts by HKMA Increases understanding and compliance with the Ordinance Ongoing public consultations for licensing regimes Ensures regulatory framework reflects local circumstances and international practices Key Takeaways Stablecoins in Hong Kong’s Evolving Financial Landscape What Are Stablecoins? Stablecoins are a type of cryptocurrency that aim to keep their value steady. They usually link their price to another asset, such as the US dollar or the Hong Kong dollar. Most stablecoins in Hong Kong are called fiat-referenced stablecoins, which means they are tied to regular currencies. Private companies issue these coins, not central banks. The most common stablecoins in Hong […]

Are Algorithmic Stablecoins Still Safe for Investors

Investors face high risk when considering algorithmic stablecoin investments in 2025. Many now worry about sudden losses in value. The collapse of TerraUSD (UST) and the decline of Binance’s BUSD token shook the stablecoin market. In May 2022, Terra’s UST and LUNA tokens collapsed, causing $60 billion in investor losses and leading to hedge fund bankruptcies.Technical, economic, and operational risks can threaten investor safety. Smart investors seek practical ways to protect their money. Key Takeaways What Is an Algorithmic Stablecoin How Algorithmic Stablecoins Work An algorithmic stablecoin uses computer code to keep its price steady, usually close to $1. Unlike other stablecoins, it does not hold cash or crypto as backup. Instead, it relies on algorithms and smart contracts to control how many tokens exist. When demand for the algorithmic stablecoin rises, the system creates more tokens. If demand falls, it removes tokens from the market. This process tries to keep the price stable, much like a central bank manages a country’s money supply. This design means the algorithmic stablecoin does not need traditional collateral. The system depends on market confidence and the rules set in its code. Collateralized vs Algorithmic Stablecoins Stablecoins come in two main types: collateralized and algorithmic. Each type has a different way to keep its value stable and faces unique risks. Type How It Maintains […]

These digital assets aim to keep their value steady by linking their price to stable assets such as the us dollar or gold. This approach helps reduce the wild price swings seen in other cryptocurrencies. Stablecoins offer several features that set them apart: People and businesses use stablecoins for payments, savings, and trading because they can trust the value will not change much. Types of Stablecoins Stablecoins come in different forms, each with its own structure and risk profile. The most common types include fiat-collateralized stablecoins, crypto-collateralized stablecoins, and algorithmic stablecoins.
