Behind High Energy Consumption of Blockchain: PoS Consensus Mechanism To Be A Solution
The energy consumption of Blockchain
Recently, Elon Musk, the founder of Tesla, posted on Twitter saying that: Bitcoin can consume too much in mining and transaction process, such excessive fossil fuel consumption will result in negative impacts on the ecosystem. The Ethereum co-founder Vitalik Buterin also noticed the high power consumption problem in Blockchain technology. He presented that Ethereum would change its consensus mechanism from PoW to PoS to reduce the power consumption caused by the mining process in PoW-based technologies like the Bitcoin. From a global view, energy consumption issues are concerned by an increasing number of countries. To urge the efficient power usage, many countries and organizations have set up environmental protection plans, such as the UN’s SDG (Sustainable Development Goals) and the US carbon neutrality, etc.
In this context, the future development of a technology need to consider the sustainable development and environmental friendliness as one of the important metrics and goals. As an emerging technology for privacy protection, Blockchain presents excellent protection capabilities. However, such capabilities rely on the large-scale computing resources and result in a large amount of power consumption. Part of the reasons for such high power consumption are due to the PoW (Proof of Work) consensus mechanism which has high demands on the performance of the Blockchain nodes.
Besides energy consumption, other concerns of the consensus mechanism
The technology of the base layer of the Blockchain has the advantages like anonymous, Immutable, decentralized and so on. To achieve these advantages, Blockchain enhances the privacy and protect the transaction process by increasing the cost of network participation. The core concept of the early-stage PoW consensus mechanism is based on the workload cost. The credibility need to be proved by the cost of a lot of work. In this case, the machines that maintain the ledgers (also referred to as mining nodes) need to continually crack complex math puzzles to obtain Bitcoin as rewards. This computing process not only needs to rely on a large amount of computing resources, but also sacrifices part of the scalability on the Blockchain to ensure safety. When it comes to the boosting growing of transaction volume, this mechanism will not be able to meet high-speed and large-scale processing demands. Based on such limitations of PoW, PoS (Proof of stake) is gaining more and more attention to work as a consensus mechanism with low resource consumption and guaranteed decentralization, safety and scalability.
In a PoS-based Blockchain system, nodes do not have to consume much power to compete for accounting rights. The priority of accounting rights is measured by the amount of stake holdings. In this way, the nodes no longer consume a large amount of electricity to calculate the hash functions, thereby solving the high energy consumption issues in PoW mechanism. In spite of the improved efficiency in PoS, the safety of the mechanism is affected. Therefore, in order to ensure the reliable operation of PoS, the researchers need to develop reliable algorithms from the trade-off among the decentralization, safety and scalability.
Unique advantages of PlatON PoS
With the issues caused by the PoW mechanism has been widely criticized, more and more Blockchain technologies inclined to choose or transit to the PoS-based consensus mechanisms. This results in a boosting growing of the PoS-based Blockchain frameworks in recent years. As the world leader in computing privacy area, PlatON has rooted and researched in privacy computing technologies many years. PlatON’s research and practice in consensus mechanisms are also forward-looking. The PPoS (PlatON PoS) consensus mechanism uses off-chain identity, credit mechanisms and procedural arrangements to provide a scheme to select a number of verification nodes from many participating nodes as fair and randomly as possible. Hence, PPoS can effectively inhibit bribery, collusion, etc., and reduce the consensus cost and improve the system scalability by optimizing technical details. Meanwhile, ensuring the decentralization and scalability, PlatON further enhances the system safety by combining the experiences in computing privacy area. The Alaya network based on PlatON PoS has been operating stably and efficiently for a long time, successfully solving the problem of over-centralization of the system, reducing network communication complexity and message complexity, improving consensus efficiency and the entire Blockchain transaction processing performance. In this case, the safety and liveness of the technology are verified. PlatON has been able to improve its PoS mechanism through its attention to every detail, continuous attempts, active exploration of cutting-edge areas, and forward-looking plans in the future development. Next step, PlatON will continue actively promoting the efficient network operation with high-quality code, providing efficient, high-availability, distributed and sustainable infrastructure applicable for diverse industrial and commercial use cases, and supporting the exchange of data flows in the global world.

Totalcare Dental and Dermal Adds Porcelain Veneers for Bondi Junction Patients
Australia, 22nd Oct 2026 – Totalcare Dental and Dermal, an innovative dental and dermal practice in Bondi Junction, Sydney, has announced the availability of porcelain veneers for local patients. Porcelain veneers are thin shells of ceramic, custom-made to cover the front surface of teeth.

The practice offers cosmetic dentistry treatments alongside general dentistry, orthodontics, dental implants and emergency care. It also provides teeth whitening and sedation dentistry. The information in this release is general in nature and is not a substitute for a dental assessment.
What Porcelain Veneers Involve
Veneers are made from medical-grade ceramic and are bonded to the teeth with a dental adhesive. The practice states that they are used to address chips, cracks, gaps and discolouration. Because they cover the visible surface of a tooth, they are often considered by patients who want to change the shape, size or colour of several front teeth at once.
The practice distinguishes porcelain veneers from composite veneers. Composite veneers are typically sculpted directly onto the tooth in a single visit, whereas porcelain veneers require more planning and multiple visits. The additional time reflects the fact that porcelain veneers are made to order from impressions of the patient’s teeth.

“Porcelain veneers are a cosmetic treatment that is planned carefully before any work begins,” said Ishara Goonewardene, Owner of Totalcare Dental and Dermal. “The first conversation is about what the patient would like to change and whether veneers are the right way to approach it.”
Stages of Treatment
Treatment begins with a consultation, in which the dentist discusses the patient’s goals and assesses whether veneers are suitable for their teeth. The practice describes this stage as consultation and planning.
The second stage is preparation. A small amount of enamel is removed from the front of the teeth so that the veneers can sit in place. Enamel does not regrow, so removing it is generally regarded as irreversible, which is one reason the decision is made after a full consultation rather than on the first visit.
In the third stage, impressions of the prepared teeth are taken and used to create veneers that match the shape and size of the patient’s teeth. The final stage is bonding, in which each veneer is attached to its tooth.
Suitability and Aftercare
The practice states that porcelain veneers may suit people who want a natural-looking and aesthetic result, people who need to cover more significant imperfections or damage, and people who prefer an option that requires little maintenance. Whether they suit an individual patient depends on the condition of the teeth and gums, which the dentist assesses at the consultation.

Aftercare is straightforward. The practice advises regular brushing and flossing and avoiding excessive force, such as biting on hard objects. Routine check-ups with a dentist allow the condition of the veneers and the surrounding teeth to be reviewed. Veneers can wear over time, as natural teeth do.
A dentist may recommend other options where veneers are not suitable, such as teeth whitening for discolouration or orthodontic treatment for alignment. The practice offers both, so alternatives can be discussed at the same appointment as the veneer consultation. Patients who feel anxious about dental work can also ask about sedation dentistry, which the practice provides.
Looking Ahead
The practice is located at Shop 3, Ground Level, 1 Spring Street in Bondi Junction and is open Monday to Friday from 8 am to 5 pm. The announcement forms part of its wider cosmetic and general dental services.
“Patients considering veneers benefit from having the steps and the alternatives explained before they decide,” Goonewardene said. “Totalcare Dental and Dermal expects to continue offering consultations for patients who would like to understand their cosmetic dental options.”

Specialty Coffee Boom Puts Seoul Coffee Scene on the Global Map
ACR (Alegria Coffee Roasters) is a Seoul, South Korea-based specialty coffee brand founded in 2011. The company operates five directly run stores in Seoul’s Gwanghwamun and Pangyo Techno Valley areas, roasts under HACCP food-safety certification, and sources beans it says rank in the top 10 percent of available quality through annual origin visits. ACR opened its first overseas location in Kuwait in 2025 and has been selected to join the Roaster Village program at World of Coffee Tokyo 2027. More information: www.acrkorea.com / Instagram @acr_korea . A decade of quality-driven growth has turned Seoul into one of the world’s most closely watched coffee cities — and local roasters like ACR are starting to take that reputation abroad.
SEOUL, South Korea, 22nd Oct 2026 – Over the past decade, Seoul’s coffee scene has quietly built an international reputation. Specialty roasteries once known mainly to local enthusiasts are increasingly cited by coffee professionals and travelers abroad as some of the most interesting in the world, as Korean brands push beyond single-origin sourcing and competition-level cupping scores into export and overseas retail.

Among them is ACR (Alegria Coffee Roasters), a Seoul-based specialty coffee brand that has operated since 2011. The company sources what it describes as beans in the top 10 percent of available quality, with staff holding Q-grader certification — the industry’s standard credential for professional coffee tasters — who have served as judges at international coffee auctions including the Ecuador Farmers Collection and Best of Yemen. ACR said its team travels to origin countries each year to select beans directly from producers, and its roasting operation holds HACCP food-safety certification.

ACR runs five directly operated stores in Seoul — two in the Gwanghwamun area and three in the Pangyo Techno Valley district — staffed entirely by full-time, professionally trained baristas. The company said its stores served roughly 300,000 cups of coffee in the first half of 2026 alone, reflecting the broader growth of Seoul’s specialty coffee market. Industry watchers frequently mention ACR in the same breath as other well-known Seoul-based specialty roasters such as Momos Coffee, Coffee Libre, Fritz Coffee and Bean Brothers.

ACR’s growth has extended beyond Korea. According to local media reports, the company opened its first store in Kuwait in March 2025 under a master franchise agreement with a Middle Eastern holding company that also operates the burger brand Thinnies, alongside construction, interior and marketing businesses. ACR has said it aims to grow to more than 20 locations across the Middle East and North Africa over the next five years, becoming, by its own account, the first Korean specialty coffee brand to enter the region.

The company has also been selected to take part in the Roaster Village program at World of Coffee Tokyo, scheduled for April 28-May 1, 2027, at Tokyo Big Sight, where it plans to present its coffee to an international trade audience as one of a small number of roasteries representing Korea.
“Seoul’s specialty coffee scene has changed enormously over the past ten years, and we’re starting to see that recognition translate into opportunities overseas,” said Giyong Yoo, CEO of ACR. “Kuwait was our first step outside Korea, and we’re hearing growing interest from partners in other markets who want to bring ACR to their own countries.”
ACR said it plans to continue expanding its presence at international trade events and through overseas retail partnerships in the coming year, alongside its five Seoul stores and online sales through its direct-to-consumer channels.

Emergency Dentist Perth Helps Patients With Urgent Dental Care
WA 6060, Yokine, Australia, 22nd Oct 2026 – Emergency Dentist Perth, a pioneering urgent dental care provider based in Yokine, has announced details of the urgent dental care it provides to patients across Perth. The clinic treats toothache, broken or chipped teeth, knocked-out teeth and infections, and is open seven days a week.

The clinic is led by Dr Anand Ponnusamy, Principal Dentist, and operates from Shop 6/201 Flinders Street in Yokine. It offers general and emergency dental services to patients who need to be seen urgently, as well as to those who need routine care. The information in this release is general in nature and is not a substitute for a dental assessment.
What the Clinic Treats
The clinic lists a range of urgent problems that it treats. These include toothache and pain relief, broken or chipped teeth, knocked-out teeth, emergency extractions, and infections, including abscess drainage and antibiotics where appropriate. It also lists wisdom tooth pain, pulpitis and gum swelling among the problems that patients present with.
Dental emergencies tend to occur outside normal working hours, and many patients are unsure whether a problem can wait until the next available appointment. Severe pain, swelling, a knocked-out tooth or a broken tooth are generally reasons to seek care promptly, and the clinic encourages patients to call when in doubt.

“Patients often phone when they are in pain and are not sure what to do next,” said Dr Ponnusamy. “The first step is to find out what has happened, and that can usually be done over the phone before the patient arrives.”
What Happens at an Urgent Visit
The clinic describes a three-step process for urgent visits. The first is a careful assessment, which may include X-rays or other scans to find the source of the problem. The second is a personalised treatment plan, which the dentist decides with the patient. The third applies only where needed, and involves a referral to a specialist if the problem calls for more specialised care.
The clinic states that it aims to relieve pain and stabilise the tooth first, with any further treatment discussed once the immediate problem has been addressed. Where a tooth has been damaged, the type of treatment depends on how much of the tooth remains and on the health of the surrounding gum and bone.
Booking and Access
The clinic is open seven days a week, with evening appointments available on most days. Patients can phone the clinic, book online through HealthEngine or send a message through the contact form on its website. Calling ahead allows the team to prepare for the visit and to advise on what to do in the meantime.

The clinic’s website also provides guidance on what to do before reaching the clinic, with separate information for common situations such as a broken tooth or a knocked-out tooth. Patients are encouraged to seek advice from a dentist rather than rely on general information alone.
Patients are advised to mention any medical conditions and the medications they take when they call or arrive, because this information helps the dentist plan treatment. Payment options through Afterpay, Zip Pay and Zip Money are listed on the clinic’s website.
Looking Ahead
The announcement forms part of the clinic’s wider dental services for patients in Perth, including those who live near Yokine and in the surrounding northern suburbs. Dr Ponnusamy is also the Principal Dentist at Radiant Smiles Dental Care, which operates from the same address.
“The aim is to make it straightforward for a patient in pain to reach a dentist and to understand what will happen when they arrive,” Dr Ponnusamy said. “The clinic expects to continue offering urgent appointments throughout the week as demand requires.”
