LikeLib2.0 Technical Features, Redefining Public Chain

Published

on

Based on the country’s strategy to promote the development of blockchain, we focus on the core issues of blockchain applications in various fields, take typical blockchain applications as an important breakthrough, promote breakthroughs in key application technologies of blockchain, and study blockchain service architecture, data Key technologies such as access technology, hybrid storage, data source, cross-chain and sharding, blockchain and IoT intelligent system integration, and develop a basic platform for blockchain services, in blockchain education and training, e-government, supply chain, and carry out application demonstrations in key areas such as finance to open up the innovation chain, application chain and value chain, thus providing common and secure blockchain basic support capabilities.

Recently the technical features of LikeLib2.0 public chain system are announced through the media.

LikeLib2.0 provides a secure and stable blockchain service basic platform, covering more than 3 core modules with independent intellectual property rights, such as data connection, hybrid storage, and cross-chain technology, which is able to quickly build solutions for typical application scenarios.

Compared with LikeLib1.0, LikeLib2.0 has a higher level of improvement in core technology architecture, and the transaction speed is about 10000TPS.

The newly released 2.0 system will not only merge transaction program fees, but also copy forks of the blockchain and increase the volume of transfer transactions. The average transaction value can be distributed among the running nodes.

In addition, there have been steady improvements in supporting smart contracts, exchangeable consensus mechanisms, and various storage networks. It can replace the blockchain consensus mechanism and the basic IPFS distributed storage network according to different factors (such as transaction volume), which can store a large amount of data outside the chain.

LikeLib2.0 uses database fragmentation technology. Within the database of LikeLib2.0 public chain system, only a small part of the input transactions need to be processed, and a large amount of verification work can be completed through other conventional parallel processing on the network.

Here, BTC and LikeLib seem to be merchants from two countries. The two parties cannot trust each other and use different currencies, so they cannot directly trade.

Therefore, the two parties negotiated a set of rules (equivalent to a relay chain protocol) and established a special trading venue to handle transactions, jointly managed by large merchants (equivalent to gateways) in their own country as representatives. These large merchants also need to have a sufficient amount of assets as security.

The whole process is called a cross-chain bridge, which has technical advantages such as multi-signature technology/ring signature technology/hash locking.

LikeLib2.0 uses Lightning Network transactions and zero configuration transaction channels.

Both parties transfer funds to a common payment channel and conduct transactions by transferring funds from one end to the other. The existing hosting solutions on the Lightning Network only manage their users’ funds on one or a few, and they will not use one channel with each user. Instead, an internal private ledger is kept to record when the funds belong to the user.

Therefore, users do not have to wait for the payment channel to be broadcast to the chain. The result is a decentralized network of custodians, with each custodian running a centralized subnet with users.

Earlier we mentioned the ring signature technology in the LikeLib2.0 cross-chain bridge. The ring signature is named because a certain parameter implicit in the signature is composed according to certain rules. However, many schemes proposed later do not require the structure of the signature to be a ring, as long as the formation of the signature satisfies the spontaneity, anonymity and group characteristics, and it is also called a ring signature.

In fact, the security of the ring signature technology scheme is quite high, such as: unconditional anonymity, unforgeability, unconditional anonymity of the signer, and the signer can freely specify his own anonymity range, forming a beautiful ring logic structure, which can realize group signatures The main function of but does not require trusted third parties or group administrators.

Ring signature is a special group signature. There is no trusted center and no group establishment process. For the verifier, the signer is completely anonymous.

In terms of zero-knowledge proofs, in theory, it is possible to prove something to everyone else without exposing anything significant, and the volume of the generated proof is small, the proof cost is very low, and it has nothing to do with the amount of calculation that needs to be proved.

LikeLib2.0 uses the generation algorithm (G) to generate public parameters for the proposition, the proof algorithm (P) to generate the proof of the satisfiability of R1CS, and the verification algorithm (V) to verify the proof and other technical methods and means to finally generate the proof. It can be proved that there is a secret value reset equation satisfied without revealing the secret.

Data traceability, from the perspective of application, focuses on the process and method of tracking.

The “decentralized and distributed” technology of LikeLib2.0 records all information publicly on the “public ledger”, and can only be entered and cannot be modified. Due to the feature of multiple parties jointly maintaining the simultaneous ledger, the traditional information island problem is broken and decentralized management is realized.

In this open distributed accounting system, the blockchain provides users with openness and consensus; decentralized and transparent transactions and anonymity for both parties.

The data traceability annotation is a technique for tracing the source, reproduce the historical state and evolution process of the data according to the trace path, and realize the redirection of the historical data archives.

The World Wide Web has continued to iterate for thirty years before it has today’s prosperity and “Internet +”. If we still have confidence in the blockchain in 2020, perhaps we should give it more time. Obviously, the LikeLib2.0 public chain system has given the blockchain industry a gratifying answer in 2020.

NexFabric Debuts Human-Verified Industrial AI for Laser Cutting at EuroBLECH 2026

Published

on

Hannover, Germany, October 21st, 2026, FinanceWire

Italian-built NexCut helps sheet metal shops tell a settings problem from a machine fault, and gives newer operators a guided way to learn what veterans know.

NexFabric today presented NexCut in Europe for the first time, at EuroBLECH 2026 on the stand of Esautomotion (Euronext Growth Milan: ESAU), Hall 15, Stand E28, after a first showing at CIIF in Shanghai. NexCut is the first laser-cutting application of the NexFabric industrial AI platform. Built in Italy, it pairs AI-assisted analysis with checks the operator confirms, so manufacturing teams can diagnose production problems without handing the decision to the machine.

Factories are losing the people who know their machines best. In Germany, 12.9 million workers, close to 30% of the workforce, will reach retirement age by 2036, according to the Federal Statistical Office. In Italy, companies reported difficulty filling 47.8% of planned hires, with CNC operators and welders among the hardest roles to fill, according to a CGIA analysis of Unioncamere Excelsior data. NexCut is built for that handover. A junior operator learns the diagnostic routine on the job, guided step by step, instead of spending years picking it up beside a veteran. Every diagnosis is saved as a procedure the next shift can reuse.

NexCut addresses a practical challenge in laser cutting: telling a problem with process settings from an issue with the machine or its hardware. Take a common case. Dross starts building on the underside of the parts. A less experienced operator may slow the cut or raise gas pressure. If the real cause is a dirty lens or a worn nozzle, that change wastes material and the fault stays. NexCut has the operator check the hardware first and confirm what they find. If there’s a hardware problem, it won’t clear the machine to run until it’s fixed.

Here’s how it works. Each laser cutter gets its own NexCut kit: a touchscreen operator station at the machine and a connected hardware module that brings in process signals from the cutter. When cut quality drops, NexCut combines those signals with physical checks the operator carries out and confirms, covering the lens, gas, focus position, cutting height, nozzle and machine stability. It narrows down the likely cause, explains why, and points to the fix. The operator makes the call. Every step is logged, so the process stays traceable and repeatable, and a central dashboard gives production managers a view across all connected machines.

“Running a laser cutter well takes years of experience, and even experienced operators still make mistakes,” said Stefano D’Andria, CEO & Founder of NexFabric. “NexCut is there to help and teach. Any operator can use it, whatever their experience, and the decision always stays with the person at the machine.”

The first proof of concept is running under real operating conditions at Soluzioni Markaurelio S.r.l. in Avezzano, Italy. It is testing NexCut against clear targets: an average guided diagnosis of 7 to 11 minutes, a 50 to 70% reduction in setup time, startup scrap and machine stoppages, and new operators working on their own within two to four weeks.

NexCut is built for manufacturers across Europe that run laser cutters. Operators get step-by-step guidance at the machine. Owners keep the know-how in-house when experienced staff leave. NexFabric plans to work with multiple industrial partners and dealers, broadening access while preserving manufacturer choice.

“Industrial AI must increase human decision-making capability, not replace it,” D’Andria added. “We’re starting in Italy, where our R&D is, and building for factories across Europe.”

D’Andria is at EuroBLECH through October 23 and available for interviews at the stand. To book a time, contact Orian Tal at orian@thepitch.media.

Rabbi Steve Karro’s Message: Give Something Back Before the Holidays Arrive

Published

on

Miami, Florida, 21st October 2026, ZEX PR WIRE, Rabbi Steve Karro is asking his community to make one concrete act of giving part of their holiday preparation this year.

A season that asks something of us

Every year, the weeks before the holidays fill up fast. Cleaning, cooking, travel, gifts. Rabbi Steve Karro has spent decades studying the parts of Jewish tradition that ask us to slow that rush down and make room for someone else.

As a rabbi and scribe based in Miami Beach, Florida, he sees the holiday season as more than a checklist of preparations. He sees it as a yearly reminder to look outward.

“Every situation, I ask what the Creator expects from me,” Rabbi Karro said. “Before the holidays, the answer is usually simple. Give something. Give it now, not later.”

The invitation

Rabbi Karro is encouraging people in his community to take on a simple practice ahead of this holiday season: one act of direct giving to someone nearby, done before the holiday itself begins, not during it and not after.

“It does not need to be large,” he said. “It needs to happen before the holiday starts, not get folded into it. That timing matters. It says the giving came from you, not from the season telling you to.”

Why the order matters

Rabbi Karro draws a distinction between giving that happens because a holiday requires it, and giving that happens because a person chooses it ahead of time.

“When you give during the holiday, you are following the calendar,” he said. “When you give before it, you are following your own decision. Both are good. But the second one changes something in you.”

He points to family life as the frame he uses to think about this.

“When your closest family is happy, and the people around them are happy too, that is the real measure,” he said. “Giving before the holiday is one way to widen that circle a little further out from your own table.”

What giving back can look like

Rabbi Karro is not prescriptive about the form giving should take. He suggests people start with someone they already know needs something, rather than searching for a cause far from home.

“Start close,” he said. “A neighbor. Someone at your synagogue. Someone in your family nobody has checked on in a while. The person right in front of you is usually the answer.”

He also encourages people to think about what they can give beyond money: time, a skill, a meal, a conversation.

“Everyone has something they know how to give,” he said. “Teaching, cooking, fixing something, listening. Find yours and give it before the holiday, not during it.”

A practice, not a one-time gesture

Rabbi Karro hopes this becomes something people return to each year, not a single gesture tied to this season alone.

“I want to see this duplicated,” he said. “Not from one person, but from many people who hear about it and decide to do their own version. That is how something small becomes something that lasts.”

He also connects the practice to teaching, which he considers central to his work as a rabbi and scribe.

“Teaching what I have learned means more people can do good for the people around them,” he said. “That is the whole point.”

About Rabbi Steve Karro

Rabbi Steve Karro is a rabbi, scribe, artist, and teacher based in Miami Beach, Florida. Born in Russia, he moved to Jerusalem at age 10 and began his Hebrew education there. At 13, he continued his studies at Yeshiva Ponovich in Bnei Brak, and by 19 he had earned his rabbinic certificate and diploma. Rabbi Karro works internationally as a Judaica calligraphy and oil painting artist, and as a scribe specializing in restoring old Torah scrolls, writing new Torah scrolls, mezuzahs, and tefilin, and checking Torah scrolls, mezuzahs, and tefilin for communities around the world.

Sundas Naqvi: Moving Cities Does Not Mean Leaving Your Sound Behind

Published

on

Chicago, Illinois, 21st October 2026, ZEX PR WIRE, Chicago jazz and folk vocalist Sundas Naqvi shares the lesson she learned when she moved her music from southern England to the American Midwest, and what she now tells other musicians who relocate.

Leaving One Sound for Another

Sundas Naqvi grew up in southern England, singing in school choirs and small community concerts before she found jazz and folk music at university. That sound, built around British choir traditions and acoustic folk, was the only musical language she knew.

In her late twenties, she moved to Chicago. The city had its own musical history, built on blues, jazz clubs, and a folk scene that worked differently than anything she had performed in before. She had to figure out where her voice fit inside it.

“I thought I was bringing a finished sound with me,” Naqvi says. “What I actually brought was a starting point.”

What Changed, and What Did Not

Naqvi did not rebuild her style from scratch. The jazz standards she loved stayed. The folk influences she picked up in England stayed too. What changed was how she used them.

Chicago’s jazz lounges rewarded a different kind of phrasing than the rooms she had performed in back home. Its coffeehouses wanted something quieter and more conversational. Private events and seasonal festivals each asked for their own pacing. She learned to read a room the way she once read sheet music.

“The songs didn’t change,” she says. “I changed how I told them.”

That shift shaped the storytelling that now runs through her sets, songs built around resilience, family, and the small moments that connect strangers in a room. Naqvi says those themes came less from any single influence and more from paying attention to what audiences in her new city responded to.

The Lesson She Tells Other Musicians

Naqvi now volunteers with youth music education programs around Chicago, leading beginner songwriting workshops and vocal sessions. She says the musicians she meets, young and experienced alike, often make the same mistake she almost made: treating a new city, a new audience, or even a new venue as a place to perform an existing sound rather than a place to grow one.

“You don’t have to choose between where you came from and where you are,” she says. “But you do have to let the new place change you a little. If it doesn’t, you’re not really there yet.”

Her advice to musicians who relocate, or who are simply trying a new room for the first time, is to treat the first several performances as listening exercises. Watch how people react to pacing, silence, and song choice before deciding what to keep and what to adjust.

“A song that works in one room can fall flat in another,” Naqvi says. “That’s not a failure. That’s information.”

Still Bringing England Into the Room

Naqvi returns to England when she can, to see family and lifelong friends. She says those visits keep her connected to where her musical instincts started, even as her sound has grown around Chicago’s own traditions.

She still reads British literature alongside contemporary fiction, a habit she picked up long before she ever sang jazz. She spends free time exploring Chicago’s older neighborhoods and photographing its architecture, work she says sharpens the same instinct for detail she uses when she is writing a song.

“Noticing a building’s small details isn’t that different from noticing what makes a lyric land,” she says. “Both come down to paying attention to things most people walk past.”

That habit of attention, more than any single technique, is what she now tries to pass on in her workshops: slow down, notice the room, and let the place you are in actually shape the art you make there.

About Sundas Naqvi

Sundas Naqvi is an independent jazz and folk vocalist, songwriter, and occasional vocal coach based in Chicago, Illinois. She performs at neighborhood jazz lounges, coffeehouses, private events, and seasonal festivals throughout the city, blending jazz standards with contemporary folk influences. She also volunteers with youth music education programs, leading beginner songwriting workshops and vocal sessions for children in Chicago’s local arts community.
