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.

Press Release

ECOBANK BACKS MEYA MINING WITH USD 25 MILLION FACILITY

Published

on

Windhoek, Khomas, Namibia, 12th Feb 2026 – Trustco Group Holdings Ltd (“Trustco”) confirms that Meya Mining Limited (“Meya”), in which Trustco holds a minority interest, has secured a USD 25 million (NAD 400 million) financing facility with Ecobank Sierra Leone Limited, supported by Ecobank Ghana Plc. The funding marks a significant milestone as Meya advances toward full commercial diamond production under its 25-year exclusive mining license in Sierra Leone’s Kono District.

The signing ceremony took place on the opening day of the Africa Mining Indaba 2026 in Cape Town, South Africa. According to Meya, the facility will be deployed toward advanced diamond processing equipment, mining vehicles and supporting infrastructure.

Meya’s shareholders have to date invested in excess of USD 100 million in the development of the resource and initial establishment of the mine. The financing represents a significant vote of confidence by a leading pan-African banking group in the quality, scale, and long-term geo-economic potential of the Meya diamond asset.

According to Meya, the facility is expected to stimulate local supply chains by routing payments through Sierra Leonean accounts, creating and sustaining over 400 direct jobs with more than 90% of employees sourced locally, and strengthening Sierra Leone’s position in the global diamond industry through traceable, responsibly mined stones. The transaction is also expected to encourage further investment in beneficiation, including cutting and polishing, to maximise national value capture.

Quinton Z van Rooyen, Deputy Group CEO of Trustco

Quinton Z van Rooyen, Deputy Group CEO of Trustco

As previously disclosed, Trustco’s exposure to Meya comprises an indirect equity interest and a loan receivable of approximately USD 46 million. Trustco therefore remains both a long-term stakeholder in the project and a significant creditor with a direct economic interest in the sustainable advancement, value preservation, and orderly commercialisation of the mine.

Quinton Z van Rooyen, Deputy Group CEO of Trustco, commented: “The decision by Ecobank to commit USD 25 million to Meya is a powerful external validation of what we have long maintained – that the Meya asset is of exceptional quality with multi-generational potential. For Trustco, as both equity holder and significant creditor, this facility de-risks the path to commercial production and brings us closer to realising the full value of our investment. It also sends a clear signal to the broader market that serious institutional capital is now flowing into this project.”

Shareholders are advised that the facility has not been concluded at Trustco level. Trustco has not approved the facility at board, shareholder, subsidiary, or group level, and has not provided any guarantees, sureties, undertakings, consents, or security in respect thereof. The facility does not constitute a transaction by Trustco requiring categorisation or approval under the JSE Listings Requirements.

The full press release issued by Meya Mining and Ecobank is available for viewing at the following link: https://www.facebook.com/share/p/1F4B2GR4Tk/?mibextid=wwXIfr

Shareholders will be kept informed of any further developments that are price-sensitive or otherwise require disclosure.
