Lumino Ceremony: Building the Privacy Protection Infrastructure
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.

TipRanks Expands Its Mission to Democratize Institutional Investing with Launch of First ETF Powered by Its Proprietary Data
New York, United States, July 9th, 2026, FinanceWire
The launch of RANK marks a major milestone as TipRanks extends its data and analytics beyond research into investable products.
TipRanks, the leading financial research and investment intelligence platform trusted by millions of investors worldwide, today announced the launch of the Defiance KSM TipRanks Analyst ETF (NYSE: RANK)—the first exchange-traded fund built on a proprietary TipRanks index.
For more than a decade, TipRanks has transformed how investors access and evaluate Wall Street research. By bringing transparency and accountability to analyst recommendations and institutional investment signals, the company has helped level the playing field between retail and institutional investors. Today, TipRanks data powers investment decisions for millions of investors and is integrated into many of the world’s leading banks, brokers, wealth managers, and financial media platforms.
The launch of RANK represents the next evolution of that mission.
Rather than simply providing investors with institutional-grade insights, TipRanks is now enabling those insights to become investable products. The ETF transforms Wall Street’s highest-conviction analyst recommendations into a transparent, rules-based investment strategy, giving investors a systematic way to access the ideas that have traditionally been available only through institutional research.
“At TipRanks, our mission has always been to make institutional-quality investment intelligence accessible to every investor,” said Uri Gruenbaum, CEO and Co-Founder of TipRanks. “Over the past decade we’ve built one of the world’s largest and most trusted financial intelligence platforms. Launching our first ETF is a natural extension of that vision. We’re moving beyond helping investors make better decisions—we’re enabling investment products themselves to be powered by our data. We believe this represents the future of investing.”
The ETF tracks the TipRanks US Momentum Analysts Index, a proprietary methodology that combines two of the market’s most closely followed investment signals: Wall Street analyst conviction and positive price momentum. The index begins with the 500 largest U.S.-listed companies, identifies those receiving the strongest analyst support, and selects the 50 companies demonstrating the strongest momentum, creating a disciplined portfolio that is rebalanced quarterly.
The index was developed using TipRanks’ proprietary analyst performance and recommendation data and is independently calculated and administered by VettaFi, one of the industry’s leading index providers. The ETF is issued by Defiance ETFs, with KSM serving as index sponsor. Together, the partnership combines TipRanks’ proprietary intelligence, VettaFi’s institutional-grade index infrastructure, and Defiance’s ETF expertise to deliver a differentiated investment solution.
“We’re constantly looking for differentiated investment strategies that can provide investors with a measurable edge,” said Sylvia Jablonski, Chief Investment Officer of Defiance ETFs. “By combining TipRanks’ unique analyst intelligence with a disciplined momentum methodology, RANK offers investors a transparent, systematic approach to identifying companies with both strong institutional conviction and favorable market trends.”
The launch also marks the beginning of a broader expansion of TipRanks’ index business. The company has developed a growing suite of proprietary indexes built on its unique financial datasets, creating new opportunities for asset managers to develop innovative investment products based on transparent, institutional-quality intelligence.
As investing continues to become increasingly data-driven, TipRanks believes proprietary analytics, artificial intelligence, and systematic investment methodologies will play a growing role in portfolio construction. The launch of RANK is the first example of how TipRanks’ technology can move beyond research and directly power the next generation of investment products in the US.
