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.

Larry’s Gutters Brings Seamless Gutter Installation in Groveland, FL
Lake County gutter contractor expands on-site fabrication services to Groveland homeowners, offering custom-fit K-Style seamless aluminum gutters backed by a Lifetime Workmanship Guarantee.
Leesburg, Florida, United States, 23rd Jul 2026 — Larry’s Gutters, a Central Florida gutter contractor serving Lake, Alachua, Marion, and Sumter counties, has extended its seamless gutter installation services to homeowners in Groveland, FL. The company’s expansion into Groveland brings on-site fabrication capabilities to a southern Lake County community where rapid residential development, established agricultural canopy, and the drainage demands of the area’s varied terrain have generated consistent demand for professionally installed seamless gutter systems among both new construction homeowners and those replacing aging sectional installations.

Larry’s Gutters has built its presence across Central Florida through a consistent commitment to custom on-site gutter fabrication and professional installation standards. The company has completed more than 5,000 residential gutter projects in the region over more than 12 years of operation, serving homeowners throughout Lake, Alachua, Marion, and Sumter counties from its Leesburg headquarters. The company holds accreditation from the Better Business Bureau and membership in the Rain Gutter Association, and backs every seamless gutter installation with a Lifetime Workmanship Guarantee that covers workmanship for the life of the installation.
Groveland, located in southern Lake County along the US-50 corridor, has experienced substantial residential development over the past two decades while retaining the character shaped by its agricultural heritage and the mature tree canopy common to rural Lake County properties. Live oak, water oak, and cypress trees are prevalent throughout the area, contributing to year-round broadleaf and organic debris accumulation in residential gutter channels. The city’s proximity to the Clermont hills and the South Lake chain of lakes introduces drainage considerations that require careful downspout planning on properties where lot grade varies across the site. Homeowners in both established neighborhoods and newer subdivisions frequently encounter the joint separation and overflow issues associated with aging sectional gutter systems.
Homeowners in Lake County seeking seamless gutter installation in Groveland, FL can contact Larry’s Gutters for a free quote and on-site assessment. The company’s installation process begins with a roofline measurement and a thorough evaluation of fascia condition, drainage requirements, and lot grade before a roll-forming machine fabricates a custom K-Style aluminum gutter run at the job site to the precise length required for each section of the home. This approach eliminates the joints and seams that allow water infiltration in sectional systems and removes the failure points that develop under the debris weight and rainfall intensity typical of Florida’s wet season.
“Groveland has been growing quickly, and we encounter two distinct situations in the same service area. Older properties with mature live oak canopy load gutters with year-round debris, and newer subdivision homes have builder-grade sectional systems that are beginning to show joint separation and sealant failure. On-site fabrication addresses both situations through the same method: a single continuous run cut to the exact length of that roofline, with no seams where water can enter and no joints that loosen under debris weight or seasonal expansion,” said Chris Knight, owner of Larry’s Gutters.
Each seamless gutter installation by Larry’s Gutters includes valley shields, also known as splash guards, installed at every roof valley to prevent water from sheeting past the gutter channel during heavy rainfall events common throughout Central Florida’s wet season. Custom downspout placement is determined on a per-property basis, with positioning informed by each home’s lot grade and drainage patterns to direct water safely away from the foundation perimeter. For Groveland properties situated on sloped lots in the Clermont hills corridor, proper downspout placement is particularly important in preventing the concentrated foundation erosion that results when discharge is directed toward the structure rather than away from it.
Groveland homeowners can also locate Larry’s Gutters’ Leesburg service location and schedule a consultation for seamless gutter installation in Groveland, FL through the company’s Google Business Profile. Larry’s Gutters serves Groveland and the broader South Lake County area from its headquarters at 1720 Leesburg Commons Ct Suite 2, Leesburg, FL 34748.
In addition to seamless gutter installation, Larry’s Gutters provides micro-mesh gutter guard installation designed for the specific canopy types common throughout Lake County, as well as professional gutter cleaning and repair services for residential properties across its Lake, Alachua, Marion, and Sumter county service area. The company offers free quotes for all services with no obligation.

Larry’s Gutters Now Offers Seamless Gutter Installation in Waldo, FL
Alachua County gutter contractor expands on-site fabrication services to Waldo homeowners, delivering custom K-Style seamless aluminum gutters sized for the slash pine flatwoods environment and the low-pitch rooflines common throughout the area.
Gainesville, Florida, United States, 23rd Jul 2026 — Larry’s Gutters, a Central Florida gutter contractor serving Alachua, Lake, Marion, and Sumter counties, has expanded its seamless gutter installation services to homeowners in Waldo, FL. The company’s entry into the Waldo market brings professional on-site fabrication capabilities to an Alachua County community where slash pine flatwoods canopy, older low-pitch residential construction, and the ongoing replacement cycle of aging sectional gutter systems have created steady demand for seamless aluminum gutter installation.

Larry’s Gutters has served Central Florida homeowners for more than 12 years, completing more than 5,000 residential gutter projects across the region from its Gainesville and Leesburg service locations. The company holds accreditation from the Better Business Bureau and membership in the Rain Gutter Association, and backs every seamless gutter installation with a Lifetime Workmanship Guarantee that covers workmanship for the life of the installation. The company has established a consistent record of quality gutter installation and maintenance in Alachua County and the surrounding region.
Waldo, situated in eastern Alachua County within the slash pine flatwoods corridor, presents a residential gutter environment that differs significantly from the broadleaf canopy areas common in other parts of the region. Slash pine needles accumulate differently from leaves, settling flat along gutter channel floors and compressing into dense mats that block drainage at downspout entries while leaving the visible surface of the channel appearing unobstructed from the ground. The housing stock in and around Waldo consists largely of single-story homes built during the 1960s and 1970s, many of which feature low-pitch roof systems that further reduce the water velocity needed to flush debris through the channel. Original sectional aluminum gutters on these properties have in many cases reached or exceeded their service life, with joint separation, sealant failure, and corrosion at seam connections among the most commonly observed conditions.
Homeowners in Alachua County seeking seamless gutter installation in Waldo, FL can contact Larry’s Gutters for a free quote and on-site assessment. The company’s installation process begins with a measurement of the home’s roofline dimensions and an evaluation of fascia condition, drainage requirements, and lot grade before a roll-forming machine fabricates a custom K-Style aluminum gutter run at the job site. Each run is cut to the precise length required for that section of the home, producing a single continuous channel with no joints or seams where debris can accumulate, water can infiltrate, or structural failure can develop over time.
“Waldo’s combination of slash pine canopy and older low-pitch rooflines creates conditions where a seamless installation makes a concrete practical difference. Pine needles pack tightly into any gap or joint in a sectional system, and the low water velocity on flat-pitch roofs means debris does not flush out naturally during rainfall. A single continuous seamless run removes those failure points entirely,” said Chris Knight, owner of Larry’s Gutters. “We have been serving Alachua County homeowners for more than a decade, and the replacement demand we see in Waldo reflects how far many of the original sectional installations in those neighborhoods have aged past their service life.”
Each seamless gutter installation performed by Larry’s Gutters includes valley shields, also known as splash guards, installed at every roof valley to prevent water from bypassing the gutter channel during Florida’s wet season rainfall events. Custom downspout placement is determined on a per-property basis, with positioning based on each home’s lot drainage characteristics to ensure water discharges safely away from the foundation perimeter. The K-Style aluminum profile used by Larry’s Gutters provides a larger water-carrying capacity than the round profile common on older installations, making it particularly well suited to the debris and rainfall load that Waldo properties encounter.
The company’s expansion into Waldo coincides with a period of increased replacement demand across the eastern Alachua County flatwoods, where original gutter installations from the 1960s and 1970s are reaching end of service life across a significant share of the local housing stock. Homeowners who have observed overflow staining, joint leakage, or sagging sections in their current systems are encouraged to request a free assessment for seamless gutter installation in Waldo, FL before the wet season reaches its peak rainfall months.
In addition to seamless gutter installation, Larry’s Gutters provides micro-mesh gutter guard installation and professional gutter cleaning and repair services for residential properties throughout its Alachua, Lake, Marion, and Sumter county service area. The company offers free quotes with no obligation.

Lucas Air Conditioning and Heating Leads as Trusted HVAC Contractor in Tavares, FL
Veteran-owned and Lake County-based, Lucas Air delivers expert AC repair, installation, and maintenance as Florida homeowners face their most demanding cooling season.
Tavares, Florida, United States, 23rd Jul 2026 — Lucas Air Conditioning and Heating, a veteran-owned HVAC contractor headquartered in Tavares, FL, continues to serve homeowners and businesses throughout Lake County as Central Florida enters its most demanding cooling season. With temperatures across the region consistently exceeding 90 degrees and humidity levels placing sustained pressure on residential and commercial HVAC systems, the company is meeting increased demand for AC repair, system installation, and preventative maintenance with the same professional standards that have earned it a 5-star rating on Google and recognition as a four-time Nextdoor Neighborhood Favorite across Lake County. July and August represent the peak demand window for HVAC contractors throughout Central Florida, making reliable, same-day service capacity and accurate diagnosis essential for homeowners and businesses that cannot afford extended downtime.

Tavares — known as the City of Lakes and the county seat of Lake County, FL — presents a distinct operating environment for HVAC systems. The area’s combination of year-round heat, elevated ambient humidity, and an extended cooling season that runs well beyond summer creates accelerated wear on key components including compressors, evaporator coils, blower motors, and electrical controls. Residential properties built near the chain of lakes experience additional humidity exposure that intensifies this wear cycle, making regular professional service especially important for homeowners throughout the area. For Tavares residents and surrounding Lake County communities, the difference between a proactive maintenance visit and an emergency breakdown call often comes down to the reliability of the contractor they establish a relationship with before a problem develops.
Lucas Air was founded in 2018 by Cameron Lucas, a U.S. Army veteran who served eight years in the 82nd Airborne Division. He built the company on the principles of Respect, Integrity, and Trust — values that carry over into every diagnostic appointment, installation project, and service call the team handles. With more than 60 combined years of HVAC industry experience across the team, Lucas Air Conditioning and Heating has grown into one of the most recognized names in residential and commercial HVAC service across Lake County and the surrounding region.
Homeowners in Tavares can access the full range of HVAC services from Lucas Air, including same-day AC repair, new system installations, $125 precision tune-ups, duct cleaning, pool heater repair, and the annual Preventative Maintenance Agreement. Property owners seeking a qualified HVAC contractor in Tavares, FL will find detailed service information, scheduling options, and current service offerings at the company’s dedicated Tavares location page. KwikComfort financing is available for new system installations, and free estimates are provided for all replacement and new construction projects.
“Tavares is home — it’s where we started, where we’re headquartered, and where the team shows up every day committed to doing the work right,” said Cameron Lucas, founder of Lucas Air Conditioning and Heating. “In a Florida summer, a reliable HVAC contractor is not a convenience — it is a necessity. We built this company to be the team that Lake County homeowners can call without hesitation, and that standard has not changed in eight years.”
Lucas Air serves Tavares and communities throughout Lake County and into Orange County, including Eustis, Mount Dora, Leesburg, Fruitland Park, Lady Lake, The Villages, Umatilla, Sorrento, Howey-in-the-Hills, Clermont, Minneola, Groveland, Winter Garden, and Apopka. The company holds Florida HVAC contractor licenses CAC1819409 and CAC1819837, carries full liability and workers’ compensation insurance, and was named Best of the Best in Heating and Air Conditioning by Style Magazine in 2025 — an honor determined entirely by reader votes across Lake and Sumter Counties. Lucas Air also holds a secondary service address at 11433 US-441 #5, Leesburg, FL, further extending its accessible footprint throughout central Lake County.
