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.

Golf Commentator Tancredi Marchiolo Turns His Attention to Medinah as the 2026 Presidents Cup Returns to a Renovated Course No. 3
- Italian-born writer on golf course architecture Tancredi Marchiolo launches a series of essays examining the restored Medinah layout, the Bendelow-to-Ogilvy lineage, and what the September team event reveals about classic design
Medinah, Illinois, Sep 10, 2026, ZEX PR WIRE — Golf writer and course architecture enthusiast Tancredi Marchiolo has announced a new series of essays timed to the 2026 Presidents Cup, which brings the biennial competition between the United States and the International Team to Medinah Country Club’s Course No. 3 from September 22 through 27. The series will look past the leaderboard to the ground itself, tracing how a 1920s Tom Bendelow design became one of the most heavily reworked championship courses in America, and what its latest transformation says about the direction of modern golf architecture.
Medinah’s Course No. 3 arrives at the Presidents Cup fresh from a full-scale redesign by OCM, the Australian firm co-founded by International Team captain Geoff Ogilvy. The project rerouted the closing holes, removed thousands of trees, widened fairways, enlarged greens, and introduced broad expanses of fescue in place of the dense parkland corridors that defined the course during its three U.S. Opens, two PGA Championships, and the 2012 Ryder Cup. For Tancredi Marchiolo, that shift is the story of the week.
“Medinah is a fascinating case because it has never stopped being rebuilt,” said Tancredi Marchiolo. “Bendelow laid it out across rolling Illinois farmland, and for a century afterward committees kept adding trees, narrowing corridors, and asking the course to play harder. What OCM has done is turn the clock back toward the original idea of width, angles, and options. Whether that produces better match play is exactly the question I want to sit with over four days.”
The essays will examine several threads that run through the writer’s broader work on the game. The first considers the tension between a course built to punish and a course built to reward thinking, a distinction Tancredi Marchiolo has long argued in favor of the Scottish links tradition. The second explores tree removal as the defining restoration movement of the past two decades and asks what is gained and lost when a parkland course is opened to the sky. A third piece looks at the peculiar relationship between architects and captains, given that Ogilvy will lead the International side across holes his own firm reshaped. Later entries will draw comparisons between Medinah and the courses on the writer’s own list of essential walks, including Muirfield, Royal Dornoch, and Circolo Golf Villa d’Este above Lake Como in his native Italy.
Tancredi Marchiolo came to golf later than to his other lifelong pursuits, taking up the game in his thirties and finding in it the same qualities he values in opera and wine: patience, attention to setting, and a refusal to be hurried. He plays for the walk as much as for the score and prefers courses laid out across natural terrain to engineered modern designs. His writing on golf leans reflective rather than technical, with a particular focus on the history of the game and the architects who shaped it.
“The Presidents Cup will be decided by putts and pairings, and I follow that with real interest,” Tancredi Marchiolo added. “But the part of the week that will still matter in twenty years is the course. If Medinah proves that a great old parkland layout can be restored rather than simply toughened, it will influence how a lot of clubs think about their own ground. That is worth writing about carefully.”
The series will be published on TancrediMarchiolo.com, with the first essay appearing ahead of the opening four-ball session on Thursday, September 24, and further installments following each day of competition. Additional writing on golf, opera, and wine is available across the author’s personal platforms.
About Tancredi Marchiolo
Tancredi Marchiolo is an Italian-born writer and devoted student of three classical pursuits: opera, wine, and golf. His writing on golf focuses on course architecture, the walking game, and the landscapes that give the great courses their character, with the links of Scotland and the historic courses of Italy forming the backbone of his own record-keeping. Beyond the course, he writes on the Italian operatic canon and the bel canto repertoire, and on the wines of Piedmont and Tuscany, reflecting a broader interest in tradition, craftsmanship, and place.

SAN JOSE, Calif. — Cardano users with assets remaining in SecondFi wallets are advised to migrate their funds to a new wallet they control and remain alert to phishing and recovery scams.
Following the June 2026 security incident involving SecondFi, users are being advised to understand the difference between asset migration and recovery before taking any action.
SecondFi reported that approximately 16.1 million ADA across 374 wallets was stolen during the security incident between June 21 and June 23, 2026. The company subsequently announced plans to wind down its wallet operations.
For users whose wallets still contain assets, SecondFi’s current official migration process is intended to move remaining ADA, Cardano native tokens and NFTs to a new Cardano wallet controlled by the user.
How the SecondFi Migration Works
Users with remaining assets should:
- Create a new Cardano wallet with a trusted provider.
- Secure the new wallet and its recovery phrase.
- Copy the new wallet’s Cardano receiving address.
- Open the existing official SecondFi application.
- Select the wallet migration option.
- Enter and carefully verify the new wallet address.
- Review the migration transactions.
- Sign the transactions using the normal SecondFi authentication process.
- Confirm that the assets have arrived in the new wallet.
Users should never enter their SecondFi recovery phrase into the migration tool.
Migration and Recovery Are Different
Users whose wallets still contain assets should follow the migration process. Those whose assets were removed during the security incident are dealing with a recovery case, which is separate from ordinary migration.
SecondFi has advised affected users to retain their original wallet and application because they may be required during the recovery process.
Users should also avoid assuming that one migration covers multiple wallets. Each SecondFi wallet should be checked and handled separately.
What Happens to Staking?
The official migration process also addresses staking-related activity.
For a staked wallet, the process may include unstaking, withdrawing available staking rewards, deregistering the existing stake key and recovering the stake deposit before transferring the relevant assets to the new wallet.
Once the assets arrive in the new wallet, users who want to continue staking will need to configure staking again.
Migration can also affect Cardano governance. Because the existing stake key is deregistered, previous DRep delegation may no longer remain active. Users who participate in Cardano governance should review their settings after migration.
Cardano Wallets Users Can Consider
There is no single wallet that is best for every Cardano user. Depending on their needs, users may consider established options such as:
- Eternl
- Lace
- NuFi
- VESPR
- Typhon
- Daedalus
- Compatible hardware-wallet solutions
Regardless of the provider selected, the destination wallet should be created and controlled by the user.
Users should never accept a wallet address or recovery phrase from someone contacting them through Telegram, Discord, X, email or another messaging platform.
Hardware Wallet Users Should Take Extra Care
SecondFi’s current guidance distinguishes hardware-wallet users from standard software-wallet migration.
Hardware-wallet users should not use the normal in-app migration flow. Instead, they may access their existing hardware wallet through another compatible Cardano wallet interface.
This distinction is important because changing the wallet application used to access a hardware wallet is not necessarily the same as transferring assets to a completely new wallet.
SecondFi Migration Scam Warning
The shutdown of a cryptocurrency wallet can create opportunities for scammers posing as support agents or recovery specialists.
Users should be particularly cautious of websites, applications or individuals claiming to offer:
- SecondFi wallet migration
- SecondFi recovery
- Wallet verification
- Cardano recovery
- Asset recovery services
SecondFi has warned users about fake applications, browser extensions and phishing attempts connected to the migration process.
Users should never:
- Share their recovery phrase or private key.
- Send ADA to someone claiming to facilitate migration.
- Install migration software from an unsolicited link.
- Give remote access to their computer or phone.
- Allow another person to create their destination wallet.
- Trust unsolicited “support” messages.
- Believe claims of guaranteed recovery of stolen assets.
Verify Every Transaction Before Signing
Blockchain transactions generally cannot be reversed once signed and submitted.
Before approving a migration transaction, users should carefully verify the:
- Destination wallet address
- Network
- Asset amounts
- Transaction fees
- Wallet provider
After migration, users should independently confirm that their ADA, native tokens and NFTs have arrived. They can also use a reputable Cardano block explorer to verify the transaction on-chain.
Key Advice for SecondFi Users
The most important principle is simple: the destination wallet must be controlled by the user.
Users with remaining SecondFi assets should use the official migration process, create a new wallet themselves, protect the new recovery phrase and carefully verify every transaction before signing.
Users affected by the June 2026 security incident should follow the separate recovery process rather than treating an emptied wallet as a normal migration.
Above all, users should remember:
Never share your recovery phrase. Never send ADA to a stranger for “migration.” Never trust unsolicited support messages. And always verify the destination address before signing a transaction.
For official information and the latest migration guidance, users should rely on SecondFi’s official channels rather than third-party links or messages.

Firm represents the latest in the Mirando family’s 110-year tradition of design innovation
United States, 10th Sep 2026 – MIKEADV CORP, the Boston-based, award-winning Integrated Marketing Communications agency known for handcrafted logo design, web development, and search engine optimization (SEO) services, is celebrating its 20th year in business. The anniversary comes 110 years after agency founder Mike Miranda’s great-uncles, Felix and Mike Miranda known as Mirando came to the United States from Italy and started the Imperial Knife Company. In a tribute to his great-uncle, MIKEADV CORP’s Founder Mike Miranda was named after him, carrying not just his name, but it seems, his gift for design.
Like MIKEADV, Imperial Knife Co. was committed to design excellence. “My great-uncle, after whom I was named, was a master of design and manufacturing craft,” explained Mike. “This talent with design runs in the family, apparently, and has been my inspiration in all my client work. As design increasingly gets absorbed into AI-driven processes, I feel the need for true design work is all the more urgent.” Virtually every early-stage client concept at MIKEADV is drawn by hand. “We’re pencil and paper guys,” Mike added. “From my brain to the paper; that’s really the only way to design something that stands out. The digitization comes later. My great-uncle understood this well, and the success he enjoyed with Imperial Knife Company bears it out.”
Felix and Michael “Mike” Mirando came to the United States from Frosolone, Italy, a town in the Molise region with a long tradition of cutlery making. They settled in Providence, Rhode Island, where the city’s Jewelry District provided an ideal environment for skilled metalworking and small-scale manufacturing.
In 1916, the Mirando brothers established what became the Imperial Knife Company. Their boyhood friend and fellow Frosolone native, Domenic A. Fazzano, later joined them in the business. The company’s earliest work was closely connected to Providence’s jewelry trade. Imperial produced simple knife components, including metal “skeletons” that local jewelers could finish in gold or silver and turn into pocket-watch chain knives.
That market began to change during the 1920s as wristwatches increasingly replaced pocket watches. Imperial responded by expanding into the manufacture of complete pocketknives, developing the high-volume production methods that would eventually make the company one of the largest knife manufacturers in America.
The Great Depression presented another challenge—and an opportunity. Consumers had less money to spend, and manufacturers needed to produce useful goods at lower prices. Imperial became known for inexpensive stamped-metal construction and colorful plastic handle materials that allowed it to manufacture pocketknives efficiently and in large quantities. Felix Mirando was a named inventor on patents covering Imperial’s innovative knife-handle construction, including a 1939 patent involving plastic material applied to a metal knife-handle assembly.
The strategy helped Imperial grow dramatically. Rhode Island historical records indicate that the company employed approximately 1,000 workers by 1929. Its Providence operation eventually expanded to four buildings around Imperial Place, becoming a major presence in the city’s Jewelry District.
By the late 1930s, Imperial’s production had reached extraordinary levels. In a later interview, Mike Mirando recalled production of approximately 10,000 pocketknives per hour. By 1940, Imperial was the world’s largest producer of pocketknives, with historical accounts placing its production at as many as 100,000 knives per day.
Imperial’s story did not end with its early Providence factories. In 1957, the company acquired the former Rochambeau Worsted Company property at 60 King Street in Providence. The facility became an important part of Imperial’s later manufacturing operations, including the production of stainless-steel tableware. After the original Jewelry District operation closed in the 1970s, the King Street plant became Imperial’s principal production facility and remained in use until 1987.
Today, Imperial’s former Providence factories remain part of the city’s industrial heritage. The former Vesta Knitting Mills buildings associated with Imperial stand around Imperial Place and are recognized within Providence’s historic Jewelry District. GoProvidence, Providence’s official tourism organization, includes Imperial Place in its self-guided Jewelry District history tour, recognizing the company’s importance to the neighborhood and to Providence’s manufacturing history.
The story of Imperial Knife is ultimately a story of immigration, craftsmanship, innovation, and American mass production. Two brothers from Frosolone entered Providence’s jewelry-manufacturing world and built a company that grew from a small workshop making components for jewelers into a global-scale producer of affordable pocketknives. Imperial helped make the pocketknife an everyday American tool—and left a lasting mark on the industrial history of Providence, Rhode Island.
“Imperial Knife thrived even during the era of mass production,” Mike reflected. “They were able to do this because they were obsessed with craft. We’re going through a similar phase now with AI, which represents mass automated design. We respond with obsessive handcraft. It’s the same family instinct, playing out in a new century.”
