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.

Bucharest, 25th of April 2024: On April 14th, the Odeon Theater hosted the second edition ofThe Bucharest Hackathon, the first hackathon in Romania dedicated to enthusiasts of newtechnologies. The competition brought together over 200 amateur and senior programmers,both Romanian and foreign, who came from Bucharest as well as from other cities in thecountry, such as Cluj, Brasov, or Craiova. For 24 hours, they coded and competed in developingsoftware projects that tested the limits of modern technologies. The top three teams won thegrand prize of a total value of $30,000, but 25 teams were also selected to receive specialprizes from the partners. For the final competition, 35 teams were selected.

The Bucharest Hackathon is attracting more and more participants. I was impressed by thelevel of competence of the teams and projects and their achievements in only 24 hours. The jurymembers, most of whom have international experience, appreciated the location andorganization, stating that they felt like they were at a hackathon in Silicon Valley. Genezio waschosen by more than half of the teams to implement their solution. Andrei Pitis, CEO &Co-founder of Genezio.

From the moment we saw the first registrations for the event, we realized that we were going tohave a completely different edition: an iconic location, much bolder ideas, much more creativesolutions, but also a considerable effort – and so it was. The Bucharest Hackathon was truly anemotional roller-coaster: from the trust in the colleagues on our team to the transformation of anidea into a product, and to the decisive moment when you find out if you are among thewinners, said Flavian Manea, CEO and co-founder of Bware Labs.

At MultiversX, we are proud to support innovation and entrepreneurship in our tech community.The partnership with The Bucharest Hackathon underlines our commitment to the future oftechnology and innovation in Romania. We are excited to see such creative ideas turned intoreality and provide the necessary support for these projects to become successful startups, Daniel Serb, VP of Business Development of MultiversX.

Each of the three winning teams received prizes worth over $10,000, as well as Amazonvouchers worth $15,000, while the teams that won special prizes from the partners received$20,000 in vouchers on the Blast platform, developed by Bware Labs, $10,000 in Geneziovouchers, two startup support prizes from MultiversX, a special prize from Google: Google NestHub (2nd Gen) smart speakers, an innovation prize from PiSquared worth $2,500 in vouchersand $2,000 in consulting vouchers from Astrarizon.

Fork_Exec, Salty, and Awesome Hackers are this year's winning teams at The BucharestHackathon

This years grand prize of $5,000 was won by the Fork_Exec team, made up of DejanuAlexandru, Opri Cezar, and Dumitru Iulia. Fork_Exec developed a software solution based onspeech recognition and artificial intelligence technologies that allows programmers to automateparts of coding based on voice commands.

Second place, worth $3,000, went to the Salty team, composed of Kerimberdi Agayev KaibovMerdan and Cihan Ilhan. They proposed an application for high school students to receiveguidance on complex math problems. The application takes the users handwriting and,combining OpenAI and AWS Cloud technologies provides the answer to the problem almostinstantly.

The third prize, of $2,000, was won by the programmers from the Awesome Hackers team,namely Puiu Rzvan, Ene Cosmina, and Manea Lucas. Awesome Hackers created a neuraldata collection platform designed to help improve cognitive function and focus.

In addition, two of the participating teams will receive support from MultiversX so that their ideascan reach the startup stage (Awesome Hackers and Mental Regression). Among the specialprize winners is also the Wildcard team, who received a Nest Hub 2nd Generation from Google.

The jury was made up of tech experts, IT entrepreneurs, and top executives from thecompanies: Genezio, Bware Labs, MultiversX, Google, Stripe, PiSquared, XOXNO, andAmazon Web Services.
