Behind High Energy Consumption of Blockchain: PoS Consensus Mechanism To Be A Solution

Published

on

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.

Jonathan Franklin of Georgetown University Highlights How Coverage Itself Shapes Missing Persons Cases

Published

on

Washington, D.C, 20th December 2025, ZEX PR WIREJonathan Franklin has reported many high-profile national stories, but one beat continues to shape his thinking: how media attention—or the lack of it—affects the outcome of missing persons cases. In his work for NPR, Franklin has drawn a clear line between editorial decisions made in newsrooms and real-world consequences for families, communities, and the public’s understanding of urgency.

Franklin, who holds a master’s degree in journalism from Georgetown University, believes one of the most underreported facts in American media is this: coverage itself is an intervention. “There’s this quiet assumption that journalism is observational. In missing persons stories, that’s never been true,” he said.

His reporting doesn’t claim to solve cases. It doesn’t make promises. What it does is document the structural gaps that determine who get covered, when, and for how long. For families who have lost someone, that timing matters. “When attention comes early, systems move faster,” Franklin said. “When it doesn’t, families are left trying to create urgency themselves.”

Patterns in Coverage, Patterns in Silence

Franklin’s reporting on missing persons cases surfaced repeated disparities in how race, gender, and perceived social status affect media treatment. His work incorporated both individual family accounts and systemic analysis, drawing on datasets that showed a consistent trend: missing persons of color receive far less media attention, even when their circumstances are similar to widely covered cases.

This dynamic, sometimes referred to as “Missing White Woman Syndrome,” was coined by journalist Gwen Ifill to describe the disproportionate media interest in young, white, middle-class women. Franklin’s work approached that phrase not as a slogan but as a hypothesis—one that he put to the test using editorial history, family interviews, and statistical context.

One key subject in his reporting was the launch of the “Are You Press Worthy?” tool by Columbia Journalism Review and TBWAChiatDay New York. This public-facing algorithm allowed people to estimate their likelihood of media coverage if they were to go missing, based on factors like age, race, and gender. Franklin covered the tool not for novelty, but for what it revealed: that journalists already knew how bias worked in theory, yet few were changing their practices in response.

Working the Gap Between Journalism and Justice

While Franklin is not an activist, his reporting has helped bridge conversations between journalists and advocates. He has covered the work of the Black and Missing Foundation and independent projects like Our Black Girls, which document missing persons stories that traditional outlets often ignore.

Instead of turning his reporting into a callout, Franklin focuses on systems. He gives newsroom leaders space to talk through editorial logic, hesitation, and resourcing issues. At the same time, he reports on the silence experienced by families who don’t receive coverage until public pressure builds—or never receive it at all.

“There’s no need to sensationalize what’s already painful,” Franklin said. “Families don’t want pity. They want momentum.”

That balance—between institutional critique and human context—is what distinguishes his work. Colleagues note that Franklin is comfortable sitting with discomfort. His stories don’t close with false resolution. They end where the story, for the family, is still ongoing.

How Journalism Shapes Outcomes

Franklin’s training at Georgetown emphasized structural thinking and accountability. Combined with field reporting experience at WUSA9 and NPR, he brings both a theoretical and practical lens to media responsibility. In his view, the idea that coverage is neutral no longer holds.

“If media attention correlates with better outcomes, then ignoring someone is not a neutral act. It’s a decision with consequences,” he said.

Franklin’s stories are now being used in classrooms, journalism workshops, and internal newsroom sessions about equitable coverage. But he resists any label that places him above the work. He sees his role as iterative. “There’s always someone we missed. The goal isn’t perfection. It’s consistency,” he said.

A Voice Built on Verification, Not Volume

Unlike social media campaigns that chase virality, Franklin’s work stays grounded in verified facts, ethical sourcing, and follow-through. He prefers to let families speak directly when possible. He also resists flattening complex stories into singular narratives of hope or tragedy.

He holds undergraduate degrees from Wofford College in English, Digital Media, and African and African American Studies. That academic background shaped his ability to frame race and justice not as themes, but as ongoing conditions that influence how stories are told and received.

His recent reporting continues to revisit the question: what happens when the public never hears your name? It’s not only about missing persons, but he also says. It’s about visibility as currency. “Attention isn’t the solution,” Franklin said. “But the absence of it is a barrier from the start.”

Looking Ahead

Jonathan Franklin remains committed to reporting stories that explore how institutions respond to crisis. Missing persons cases are one example. His broader work includes coverage of the COVID-19 pandemic’s racial disparities, public protests, court decisions, and elections. But missing persons reporting, he says, always brings him back to the core question of journalism itself: what does it mean to be seen?

For Franklin, that question is not rhetorical. It’s the difference between silence and action.

Astana Becomes Hub for OIC Food Security Dialogue

Published

on

The Islamic Organization for Food Security (IOFS) marked IOFS Day and the Organization of Islamic Cooperation (OIC) Food Security Day with a high-level roundtable on Dec.17 in Astana, where participants reaffirmed their commitment to addressing food insecurity through multilateral cooperation.

Ambassador and IOFS Director General Berik Aryn thanked the Kazakh government and people for hosting and supporting the organization, highlighting Kazakhstan’s role in advancing food security initiatives across the OIC.

Established following a proposal introduced by Kazakhstan at the 7th World Islamic Economic Forum in 2011, IOFS works to address food security challenges among OIC member states.

Aryn outlined key IOFS achievements in 2025, including the expansion of the Afghanistan Food Security Program, the launch of the Flour for Humanity – Gaza Emergency Appeal, and continued implementation of the Africa Food Security Initiative.

“With the support of Kazakhstan, Tajikistan, Turkmenistan and Türkiye, we expanded agricultural rehabilitation and capacity-building activities in Afghanistan to help communities restore livelihoods,” Aryn said. 

He added that humanitarian food aid was delivered to Gaza earlier this year with backing from Azerbaijan, Bangladesh, Kazakhstan and Tajikistan, while food system resilience projects advanced in several African member states.

Aryn also cited progress under the IOFS Strategic Vision 2031 and preparations for the Strategic plan for ensuring food security in OIC member states. 

He noted the organization strengthened partnerships through international forums, including the UN Food Systems Summit in Addis Ababa, the African Food Systems Summit in Dakar and Global Green Week in Seoul.

“The challenges of climate change, conflict, economic instability and demographic pressure remain complex. However, through unity and cooperation, we can build resilient food systems and ensure that no child goes hungry and no nation stands alone,” Aryn said.

Deputy Foreign Minister Alibek Kuantyrov reaffirmed the country’s political support for IOFS, emphasizing the importance of multilateral approaches amid climate change, water scarcity and global market volatility.

“Food security is no longer a purely national issue. It is a global challenge shaped by armed conflict, climate change, economic instability, and supply chain disruptions. No country, regardless of its level of development, is fully immune, and only cooperation and shared responsibility can address risks of this scale,” Kuantyrov said. 

He noted that 41 of the OIC’s 57 member states have joined IOFS and said interest from remaining members and international institutions continues to grow. 

Kuantyrov highlighted plans to establish an IOFS gene bank in Kazakhstan to preserve and expand plant genetic resources, alongside continued humanitarian food assistance to crisis-affected countries.

Vice Minister of Agriculture Ermek Kenzhehanuly outlined Kazakhstan’s agricultural potential and national priorities, including modernization of irrigation infrastructure and the expansion of water-saving technologies. He emphasized the importance of regional cooperation with IOFS.

“Kazakhstan has significant potential for the production and export of high-quality, environmentally friendly and organic products which are currently supplied to more than 70 countries worldwide. Annually, we produce agricultural products worth approximately $18 billion, processed agricultural products worth around $7 billion.  Agricultural exports have increased 1.5 times over the past five years, reaching $5.1 billion,” Kenzhehanuly said.

He emphasized that cooperation with IOFS goes beyond protocol, describing it as practical, results-oriented work aimed at strengthening food security, advancing innovation and improving public well-being.

The event concluded with the signing of a memorandum of understanding between IOFS and M. Kozybayev North Kazakhstan University. The agreement aims to expand cooperation in education, research and capacity development in agriculture and food security.

Jonathan Franklin of Georgetown University on Reporting Missing Persons Stories Others Overlook

Published

on

Washington, D.C, 20th December 2025, ZEX PR WIREJonathan Franklin is a Washington based journalist whose reporting on missing persons cases has helped surface a long standing imbalance in American news coverage. Through his work at NPR, Franklin has examined how race, visibility, and newsroom decision making influence which disappearances receive sustained attention and which fade quickly from public view.

Each year, hundreds of thousands of people are reported missing in the United States. News coverage plays a measurable role in shaping public awareness and search momentum. Franklin’s reporting focuses on this early window, when attention determines urgency and silence compounds uncertainty for families.

Franklin’s work frequently intersects with the issues addressed by the Black and Missing Foundation, a nonprofit dedicated to raising awareness about missing persons of color. His reporting has highlighted cases and trends often overlooked by national media while maintaining a clear separation between journalism and advocacy. The focus stays on facts, patterns, and lived experience.

Rather than centering individual tragedy as spectacle, Franklin examines systems. He looks at how cases enter editorial pipelines, how language choices frame urgency, and how assumptions about audience interest shape coverage decisions. His reporting asks why some families must fight for basic recognition while others receive immediate saturation.

In interviews, families described weeks of unanswered calls and emails before any coverage appeared. Some learned quickly which details editors wanted and which details were ignored. Franklin documented these accounts carefully, treating family members as primary sources rather than emotional color.

His reporting pairs personal testimony with data. Franklin examined research analyzing thousands of missing persons stories across television, radio, print, and digital outlets. The findings show consistent disparities tied to race and gender. Early coverage correlates with sustained attention. Absence of coverage often signals stalled interest.

Franklin presented this information without accusation. He allowed newsroom leaders and journalists to explain constraints and habits. He also allowed families to explain consequences. The tension between those perspectives drives his reporting.

This approach reflects Franklin’s graduate training at Georgetown University, where he earned a master’s degree in journalism with a broadcast and digital emphasis. His work favors structure and clarity. Sentences stay short. Claims stay narrow. Sources remain visible.

Colleagues describe Franklin as methodical in the field. He records interviews carefully. He checks language. He follows stories beyond their initial release. Missing persons coverage rarely resolves quickly, and Franklin’s reporting reflects that reality.

His NPR reporting on missing persons and media attention gaps has circulated widely. Advocacy groups, journalism educators, and researchers have cited his work in discussions about newsroom equity and ethical coverage. Franklin does not frame his role as corrective. He frames it as descriptive. He documents what coverage choices produce.

“Media attention does not guarantee answers,” Franklin said. “But the absence of attention almost always guarantees isolation. Families feel that difference immediately.”

Franklin’s earlier reporting covered public safety, race, and national crises. He reported on the COVID 19 pandemic’s impact on Black communities, protests following the murder of George Floyd, the 2020 presidential election, and January 6. These beats shaped how he approaches stories rooted in institutional response and public consequence.

A native of Columbia, South Carolina, Franklin holds undergraduate degrees from Wofford College in English and Digital Media and African and African American Studies. His academic background informs how he approaches stories involving race without collapsing complexity into slogans.

His experience at NPR and earlier work at WUSA9 positioned him to report national stories through a local lens. Missing persons cases exist at that intersection. They involve families, law enforcement, journalists, and the public. Franklin traces those connections with restraint.

Franklin’s reporting emphasizes what happens after headlines move on. Follow up matters. Families remain. Systems continue. His work reflects an understanding that journalism shapes outcomes not only through what is published, but through what is ignored.

By documenting disparities rather than reacting to viral moments, Franklin contributes to a deeper understanding of how coverage affects search efforts and public response. His reporting asks readers and listeners to consider a difficult question. Who receives attention when someone disappears, and why.

Jonathan Franklin continues to report from the field, behind a microphone, and on camera. His work reflects a belief that careful reporting, done consistently, can expose patterns hiding in plain sight.
