Lumino Ceremony: Building the Privacy Protection Infrastructure

Published

on

PlatON, a privacy AI computing network which is committed to building a decentralized collaborative artificial intelligence network and global brain, is promoting the democratization of artificial intelligence and establishing a secure general artificial intelligence. The bottom layer of its decentralized privacy protection infrastructure is based on Zero-Knowledge Proof.

What is Zero-Knowledge Proof

Zero-Knowledge Proof is a cryptographic technology to realize privacy protection authentication. The prover needs to make the verifier believe that he knows or owns a message, without disclosing any information about message which is to be confirmed. For example, if the prover wants to prove that he knows the safe box password without revealing it, he can just show some items existing in the safe box that everyone knows.

This process is Zero-Knowledge Proof. The proof needs an initial credible setting (some items existing in the safe box that everyone knows), namely a series of public parameters to help the prover build Zero-Knowledge Proof.

Deficiency of Zero-Knowledge Proof

As a cryptographic technology with both privacy protection and authentication capability, zero-knowledge proof is widely used to realize transaction verification under hidden business details in blockchain. The zero-knowledge proof system applied in the blockchain field is mainly a cryptographic algorithm called “zk-SNARKs”. At present, the existing classic zk-SNARKs algorithms include  GGPR13, PGHR13, Groth16, GM17, and new generation algorithms such as Sonic, Marlin, Plonk, which support updating public parameters. The current version of ZCash, a well-known private cryptographic currency, uses Groth16 algorithm.

From the above “safe box”, we can see that the premise for the correct operation of this kind of algorithm is existing a series of random trusted parameters. However, randomized parameters will not come out of thin air and there is no trusted third party in the blockchain. Parameters created by centralized third parties can be reconstructed in theory, and it is possible to forge proofs, which may destroy the underlying security in PlatON. Imagine that if a specific institution informed the verifier of the storage of the items in the safe box, the institution and the prover could collude and use this secret information to falsify the illusion that the prover knew the safe box password.

Therefore, it is an undoubtedly excellent idea to organize multiple participants to create these randomized parameters through Secure Multi-party Computation. In this process, single party can not reconstruct the parameters any more. Only when this activity is completed safely will the subsequent decentralized application be safe. In fact, ZCash has successfully created system parameters for Groth16 algorithm in November 2017 through its ceremony, Power of Tau.

Lumino, creating secure parameters

In order to prevent the parameters generated by the centralized mode from affecting the underlying security, PlatON started the Secure Multi-party Computation ceremony Lumino on June 21, 2021, last for   60 days. This ceremony is expected to create necessary secure parameters for the Zero-Knowledge Proof protocol.

During the Lumino ceremony, multiple participants carry out several rounds of calculation in the form of a relay, that is to say, the current participant need to use the calculation results of the previous participant as the input of this round, and the calculation output become the calculation input of the next participant as well. After a certain number of rounds, the output of the last participant is the final result of the whole ceremony, namely the system initialization parameters that Plonk thatalgorithm of PlatON will choose. Obviously, the more participants take part in the ceremony, the safer the parameters will be.

As a practical and efficient Zero-Knowledge Proof algorithm, Plonk is commonly used in PlatON projects and communities, which is characterized by a one-time initialization process, that is, running once can be used to deploy multiple applications. Providing necessary initialization parameters for Plonk algorithm through Lumino ceremony means that no one can master the secret information behind the parameters, which can be used to cheat players in the whole system. Lumino ceremony will lay a solid foundation for the security of PlatON.

MEXC Reports Sharp Surge in TradFi Futures Trading Volume in April, Led by 1,600% Jump in INTC

Published

on

Victoria, Seychelles, May 21th, 2026- Data from MEXC, a pioneer in 0-fee digital asset trading, shows that TradFi futures trading volume on the platform surged sharply in April. Among all sectors, AI semiconductor-related assets recorded the strongest month-over-month growth, with some exceeding 1,600%. This closely mirrored the rally in U.S. AI chip stocks during the same period, as more users increasingly turned to crypto platforms to gain exposure to traditional financial markets.

In April, as geopolitical tensions temporarily stabilized, risk appetite in the U.S. stock market rebounded significantly. Both the S&P 500 and Nasdaq-100 reached new all-time highs. Intel Corporation (INTC) rose roughly 50% during the month, marking its largest monthly gain in more than half a century. Advanced Micro Devices (AMD) surged 74%, becoming one of the best-performing stocks in the S&P 500. NVIDIA climbed approximately 14.4%, reclaiming the $200 level, while Taiwan Semiconductor Manufacturing Company (TSM) also strengthened alongside booming demand for AI computing power. AI and semiconductors became the dominant trading theme in the U.S. equity market throughout April.

The intensity of this rally was clearly reflected in trading activity among MEXC users. The AI semiconductor sector saw the most pronounced growth. INTC futures trading volume skyrocketed 1,684% month-over-month, AMD rose 543%, TSM gained 278%, and NVIDIA increased 213%, with all four assets posting triple-digit growth. Large-cap technology stocks and major indices also advanced strongly, with QQQ up 186%, GOOGL up 177%, and SP500 up 92%. Other assets including META (+121%), AAPL (+78%), and the NAS100 Index (+50%) also recorded significant increases.

As structural opportunities in the U.S. stock market become increasingly evident, more users are choosing to position themselves directly through familiar crypto trading platforms. Compared with traditional brokerages, crypto platforms eliminate cumbersome account-opening procedures, support both long and short Futures trading, and use stablecoins for settlement, avoiding the need to transfer funds across different financial systems. MEXC further reduces trading friction by offering zero fees on multiple Futures pairs, alongside deep liquidity and leverage of up to 100x. During the platform’s 0-Fee Fest, launched on April 15, MEXC users collectively saved more than $83 million in trading fees within just 12 trading days, with TradFi futures products contributing over $15 million of that total.

Against the backdrop of accelerating global asset rotation, demand for cross-asset allocation is rising rapidly. Currently, MEXC offers Futures pairs covering more than 130 traditional financial assets, including U.S. equities, stock indices, ETFs, precious metals, commodities, and foreign exchange products. Through a single account, users can seamlessly switch between crypto and traditional financial markets, capturing opportunities across asset classes at minimal cost.

About MEXC

MEXC is the world’s fastest-growing cryptocurrency exchange, trusted by more than 40 million users across 170+ markets. Built on a user-first philosophy, MEXC offers industry-leading 0-fee trading and access to over 3,000 digital assets.

CGTN: China-Russia relations reach new heights as Xi, Putin meet in Beijing

Published

on

CGTN published an article highlighting how China and Russia are deepening strategic coordination, economic cooperation and people-to-people exchanges during Russian President Vladimir Putin’s state visit to China. By combining trade data, historical context and expert analysis, the piece emphasizes the resilience of bilateral ties and their role in promoting a multipolar world order.

Bilateral trade has topped $200 billion for three consecutive years; more than 70% of China-Europe freight trains now pass through Russia en route to Europe; ten China-Russia Expos have been held; over 170 pairs of sister cities and provinces have been established, reflecting the growing depth and breadth of bilateral cooperation. In recent years, China-Russia collaboration has expanded across multiple sectors, yielding tangible results.

On Wednesday, the two heads of state once again witnessed the signing of multiple cooperation documents covering trade, education, technology and other areas during Putin’s state visit to China, fueling a new era of partnership between the two neighboring major countries.

During their meeting, Chinese President Xi Jinping stressed that China-Russia relations have now reached the highest level in history as a comprehensive strategic partnership of coordination for a new era and that the two sides should seize the momentum to align China’s 15th Five-Year Plan (2026-2030) with Russia’s development strategy through 2030, and deepen cooperation to serve the development and rejuvenation of both countries.

The two leaders also agreed to extend the China-Russia Treaty of Good-Neighborliness and Friendly Cooperation and issued a joint statement on enhancing comprehensive strategic coordination, deepening good-neighborliness and friendly cooperation.

China-Russia relations set example for major countries

This year marks the 30th anniversary of the establishment of the China-Russia strategic partnership of coordination and the 25th anniversary of the treaty, which defines the relationship as “non-alliance, non-confrontation and not targeting any third party” and enshrines the principle of “ever-lasting friendship and never becoming enemies.”

Xi noted that the treaty legally established a long-term foundation for neighborly friendship and comprehensive strategic cooperation, which has enabled a leap forward in bilateral relations. He said that China will work with Russia to uphold the spirit of the treaty and firmly advance China-Russia back-to-back strategic coordination.

Li Yongquan, a researcher at the Chinese Academy of Social Sciences, said the China-Russia relationship, based on “non-alliance, non-confrontation, and not targeting any third party,” transcends ideology and political systems and rests firmly on shared long-term interests and a commitment to a multipolar world. Their relationship offers a new model for major countries to get along with each other, Li said.

Since the treaty’s signing, political trust between the two countries has deepened. Annual presidential visits have become a routine, and multiple cooperation mechanisms have been established, including regular meetings between prime ministers, the China-Russia Energy Cooperation Committee, the Strategic Security Consultation Mechanism and the China-Russia Committee on Cultural Cooperation.

These mechanisms have played an irreplaceable role in promoting pragmatic cooperation, resolving bilateral issues and coordinating positions on multilateral international affairs.

China, Russia: Pillars of a multipolar world

During their talks, Xi stressed the importance of deepening multilateral coordination, safeguarding the post-war international order and international law and promoting the building of a more just and reasonable global governance system.

China and Russia have long supported each other on key issues of mutual concern. They have jointly promoted the establishment of the Shanghai Cooperation Organization (SCO), BRICS and trilateral mechanisms such as China-Russia-India and China-Russia-Mongolia cooperation. They also continue to coordinate on international platforms, such as the UN and APEC, advocating for greater representation of developing countries in global governance and promoting a multipolar, inclusive global order.

Russia is the first country Xi visited after taking office as Chinese president. Putin last year visited China to attend the SCO summit and commemorative events marking the 80th anniversary of the victory in the Chinese People’s War of Resistance against Japanese Aggression and the World Anti-Fascist War.

During Wednesday’s meeting, Putin stated that China-Russia relations have stood the test of time and grown increasingly resilient and that China-Russia cooperation is an important stabilizing factor in the turbulent world.

Cooperation boosts shared development, people-to-people exchanges

Deep political trust and close strategic alignment between the two countries has enabled steady progress in trade, culture and people-to-people exchanges, ushering China-Russia relations into a new phase of development.

Despite a complex international environment, China-Russia cooperation has shown resilience. According to China’s Ministry of Commerce, bilateral trade reached $227.9 billion in 2025, surpassing the $200 billion mark for the third consecutive year. In the first quarter of this year, bilateral trade totaled $61.2 billion, up 14.7% year on year.

Currently, the 10th China-Russia Expo is being held in Harbin, northeast China’s Heilongjiang Province, attracting nearly 300 Russian enterprises. Meanwhile, China and Russia introduced a mutual visa-free policy in 2025, triggering a tourism boom between the two countries.

The two countries have also jointly organized a range of exchange programs over the years, including the language year, tourism year, youth exchange year and cultural year. Last year, the “China-Russia Year of Culture” concluded successfully, while this year’s “China-Russia Year of Education” is expected to further strengthen generational friendship and consolidate the foundation for long-term mutual understanding between the two peoples.
