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.

Tel Aviv–Jaffa business leader Said Abulafia shares lessons from a historic Arab family-owned bakery that has served customers for nearly 150 years.
Tel Aviv–jaffa, Israel, 22nd July 2026, ZEX PR WIRE— Most businesses do not make it to ten years. According to the U.S. Bureau of Labor Statistics, only 34.7% of private-sector establishments born in 2013 were still operating in 2023. Family businesses face another challenge: only about 30% transition to the second generation, and roughly 12% remain viable into the third.

That makes Abulafia Bakery’s history unusual. Founded in Jaffa in 1879, the historic Arab family-owned bakery has operated for nearly 150 years through political change, economic pressure, shifting customer habits, and several generations of family leadership.
Said Abulafia believes the bakery’s long history offers practical lessons for modern businesses trying to survive.
“When people hear that the bakery started in 1879, they think about history,” says Abulafia. “I think about responsibility. Every generation had to make decisions that kept the business alive. That is the real lesson.”
Longevity Starts With Trust
For Abulafia, the bakery’s staying power begins with customer trust. Customers return because they know what to expect. They recognize the product, the place, and the experience.
Modern businesses often focus on attention. Abulafia believes trust matters more.
“A customer who comes once is important,” he says. “A customer who comes back with their children or grandchildren tells you something much deeper. It means the business became part of their routine.”
That kind of loyalty is not built by a single strong campaign. It is built through years of consistency.
Consistency Is Not Old-Fashioned
In a fast-moving business environment, consistency can sound plain. Abulafia sees it differently.
For a bakery, consistency is operational. Ingredients must be reliable. Production has to stay controlled. Service has to feel familiar. Small changes are noticed quickly.
“If something changes in the product, regular customers know,” he says. “They may not explain it in technical terms, but they feel it. That is why consistency is not just a nice idea. It is part of the business model.”
Adaptation Without Losing Identity
Abulafia says one of the biggest challenges for heritage businesses is knowing what to change and what to protect.
A business founded in 1879 cannot operate exactly as it did in earlier generations. Costs change. Customer behavior changes. Competition changes. Operations must improve.
At the same time, moving too far from the core identity can weaken what has kept the business going.
“You have to modernize carefully,” says Abulafia. “If you change everything, you lose the reason people trusted you. If you change nothing, you fall behind. The work is finding the line between the two.”
What Modern Businesses Can Learn
Abulafia believes the bakery’s history offers several lessons that extend beyond hospitality.
First, businesses need a clear core. They should understand what customers return for and protect it.
Second, growth should not come before stability. A weak system becomes harder to manage as it expands.
Third, businesses should listen to repeat customers. Long-term customers often notice operational problems before leadership does.
“People talk a lot about innovation,” he says. “But sometimes the best information comes from a customer who has been coming to you for 20 years and notices when something feels different.”
Pressure Reveals Weakness
The bakery has faced many periods of uncertainty, including the COVID-19 pandemic, supply disruptions, rising costs, and fluctuating demand. Abulafia says those periods forced the business to simplify and strengthen its systems.
“When conditions are easy, you can ignore problems,” he says. “When pressure comes, every weakness becomes visible. That is when you either fix the system or keep repeating the same mistakes.”
For Abulafia, pressure is not only a challenge. It is a test of how well a business is built.
A Call to Study Businesses That Last
Abulafia encourages entrepreneurs, operators, and family business owners to study long-running businesses, not only fast-growing ones.
Many modern business stories focus on rapid scale. Abulafia believes there is equal value in studying enduring companies.
“A business that lasts for generations has already answered questions many newer businesses are still trying to solve,” he says. “How do you keep trust? How do you adapt? How do you stay useful to people over time?”
Call to Action
Abulafia encourages business owners to take practical steps:
-
Identify what customers truly return for
-
Protect the parts of the business that create trust
-
Make changes gradually and measure the impact
-
Listen closely to long-term customers
-
Build operations that can survive difficult periods
“Longevity is not one big decision,” he says. “It is many small decisions made well over time.”

Knot, the leading merchant connectivity platform, has announced its partnership with RBC, Canada’s largest bank, to make RBC cards the default payment method for millions of cardholders wherever they spend. Using Knot’s CardSwitcher, RBC cardholders can set their RBC card as the saved payment method at their favorite merchants directly from the RBC mobile app, without manually entering card details. The partnership marks Knot’s first expansion beyond the United States.
Keeping RBC Top of Wallet
One of the hardest moments in payments is the first one. When a cardholder gets a new RBC card, putting it to use means hunting down every merchant where a card is already saved and updating each one by hand, so a new card often sits idle for weeks before it sees real spend. The partnership removes that friction. From the RBC app, cardholders add their RBC card to their preferred merchants in a few taps and set it as the saved payment method at the places they already spend, from the day the card is in hand.
For RBC, that means a card that goes to work immediately instead of waiting to be activated across a cardholder’s everyday spend. Placing the card as the default at the merchants cardholders use most keeps it top of wallet, turning a new RBC card from an occasional choice into a go-to payment method from the start and driving repeat spend and deeper loyalty to RBC.
Expanding into Canada with the Country’s Largest Bank
For years, Knot has built the merchant connectivity layer across the United States, linking the people, financial institutions, and merchants behind everyday spend. RBC is where that infrastructure goes international for the first time. Canada is Knot’s first market beyond the U.S., and launching it with the country’s largest bank sets the standard for every market that follows.
RBC did not become Canada’s largest bank by standing still. They move early, they invest in their clients, and they push the industry forward. That is exactly the kind of partner Knot wants to build alongside, and the reason RBC is the right first step into a new market. Bringing CardSwitcher to Canadian cardholders is the start of a longer roadmap, both for what Knot and RBC build together and for where Knot goes next.
