Kadena Confirms It Can No Longer Sustain Operations

In a post shared on its official X (Twitter) account, Kadena stated that it can no longer continue its business activities due to ongoing market conditions. The announcement reads:

“We regret to announce that the Kadena organization is no longer able to continue business operations and will be ceasing all business activity and active maintenance of the Kadena blockchain immediately.”

The company noted that a small team will remain to manage the transition and wind-down process, while all other operations are being terminated. Users and partners were advised to reach out to operations@kadena.io for any inquiries during the shutdown phase.

This announcement led to a sharp sell-off across exchanges as KDA holders reacted to the unexpected closure, driving prices rapidly lower.

Decentralized Design Keeps Kadena Blockchain Partially Alive

While operations are ending, Kadena emphasized that the decentralized nature of its blockchain will allow it to remain partially functional. The core network infrastructure will continue to exist, maintained by independent nodes and the community.

Crypto analysts have suggested that the network’s structure could enable limited activity despite the halt in development and corporate operations. However, there is currently no plan to resume full operations or relaunch the project in the near term.

KADENA PUBLIC ANNOUNCEMENT

The block contained 593 transactions worth a total of $52.6 million. The average transaction size was 0.7987 BTC, and the miner’s reward included the standard block reward of 3.125 BTC plus 0.0042 BTC in transaction fees. 

The miner used Solo CKPool to mine the block. This platform allows individual miners to compete against industrial mining giants. While Solo CKPool enables smaller operations to participate, success in solo mining remains extremely rare, as participants must compete with miners operating large-scale ASIC devices. 

Bitcoin Mining Challenges 

Bitcoin mining difficulty adjusts every 2,016 blocks to maintain an average block time of approximately 10 minutes. This adjustment increases mining difficulty, making solo mining increasingly rare. For example, a miner operating at 1 petahash per second has roughly a 1 in 4.26 million chance of finding a block. 

Currently, Bitcoin mining difficulty stands at 136.04 trillion, near all-time highs, making it extremely difficult for individual miners to find a block. 

Peter Chung, Head of Research at Presto Labs, commented: 

“Among all blockchain networks, none compare to Bitcoin in terms of decentralization. Events like these contribute to that narrative.” 

“A single miner finding a block is as rare as winning a lottery. Large miners and mining pools split tasks among themselves, gaining efficiency and stability. For most participants, joining pools is more practical, providing regular payouts. To make Bitcoin more decentralized, what’s needed are more diverse mining pools.” 

What is Solo CKPool? 

Solo CKPool allows individual miners to mine blocks using their own hardware. In this system, miners who find a block receive the full reward, while those who don’t find one earn nothing. This makes solo mining riskier but offers potentially large rewards when successful.

Sui Validators Approve Major Recovery Plan

After Cetus, a decentralized exchange, was exploited for over $220 million on May 22, Sui validators acted quickly to freeze $162 million in digital assets. The fate of these funds was determined through a governance vote concluded on May 29.

With 90.9% of validators voting in favor, the recovery proposal passed. The frozen assets will now be transferred to a multisignature wallet and held in trust until distributed to affected users, according to Sui’s official announcement.

This move signals a pivotal step toward financial restitution for those impacted by the exploit.

Validator Intervention Sparks Governance Debate

The swift validator action reignited debate within the crypto world. While decentralization purists voiced concern over the ability to freeze onchain assets, others praised the move as an effective counter to escalating security threats in DeFi.

The recovery initiative extends beyond the frozen funds. It will also leverage Cetus’ own treasury and an emergency loan from the Sui Foundation to fully restore protocol operations.

Cetus Targets Full Recovery Within One Week

Cetus expressed appreciation for the rapid community support and outlined a full roadmap for protocol recovery. The first phase involves upgrading validator nodes to transfer the funds to a multisig wallet, followed by system restoration.

The team expects a full restart within one week. All liquidity providers will regain access to their assets, while remaining losses will be compensated via a dedicated smart contract currently undergoing auditor review.

Cetus emphasized that this compensation mechanism will ensure fair restitution for all affected users.

Speaking at Consensus 2025 in Toronto, Frank Mong, COO of Nova Labs, explained how decentralized networks like Helium are reshaping the industry. Small businesses such as cafes, bars, and convenience stores can now host wireless hotspots and generate passive income.

Replacing Towers With Shared Wi-Fi

“It costs about $300,000 to build one 5G tower, and you need one on every block,” Mong said. “Instead of raising mobile plan costs, what if people simply share their Wi-Fi securely and large companies like AT&T tap into that data?”

With 95,272 mobile hotspots and 284,053 active IoT nodes, the Helium Network has become a real-world application of DePIN technology. The U.S. currently leads in hotspot density.

Major Partnerships Fuel Expansion

In 2024, Telefónica partnered with Nova Labs to enhance coverage in underserved areas. In April 2025, AT&T joined in, allowing their users to automatically connect to the Helium network when within coverage.

Mong stated, “What we achieved in the U.S. and Mexico should be replicated globally,” signaling Nova Labs’ ambition to scale partnerships across regions.

What was once a technical vision is now a business opportunity for both mom-and-pop shops and multinational telecoms. Decentralized physical infrastructure networks are not just Web3 buzzwords — they are building a smarter, fairer, and more cost-effective future for telecom.

By scanning irises through a proprietary device called the Orb, Worldcoin aims to verify human uniqueness and distribute its WLD token globally. However, experts warn that such a model, reliant on centralized hardware and control points, could become a digital panopticon rather than a tool for freedom.

Decentralization Is a Philosophy, Not Just Code

As Shady El Damaty of Holonym Foundation explains:

“True decentralization prioritizes user agency, not corporate control. Relying on custom devices and closed infrastructures contradicts that ethos.”

Even with privacy-focused tools like zero-knowledge proofs (ZKPs) and multiparty computation (MPC), El Damaty argues the system’s architecture is fundamentally flawed in its promise of decentralization.

Worldcoin, however, defends its model, stating that the World App is non-custodial and no personal data is stored. The company claims all iris data is encrypted and deleted immediately after processing.

A Pattern of Data Overreach?

Critics see a disturbing pattern. El Damaty compares Worldcoin’s biometric data collection to OpenAI’s large-scale scraping of unconsented user data, calling it a “recurring theme” of invasive tech practices marketed as progress.

World distances itself from OpenAI, insisting it neither sells nor retains personal data. But concerns remain—especially as governments in Germany, Kenya, Brazil, and most recently Indonesia push back against the project’s local operations.

Targeting the Vulnerable?

According to critics, Worldcoin is focusing its biometric campaigns on developing countries, where individuals may be more easily swayed by monetary incentives without fully understanding the risks.

El Damaty warns:

“In many regions, people are being coerced into giving up sensitive data for short-term rewards.”

Biometric Divide or Digital Future?

If access to basic services becomes tied to biometric verification, it could create a two-tiered digital society, say critics—those who comply and those who are locked out.

Worldcoin says biometric enrollment is optional, and unverified World IDs can still access limited services. However, as digital services increasingly require stronger identity checks, the pressure to “opt in” may intensify.

As AI and bots proliferate online, systems that prove human identity will be essential. But how that identity is verified—with privacy, or through surveillance—may define the digital future.

In a statement on X, Bjelic said: 

“As projects evolve and mature, it’s natural for visions to evolve and sometimes diverge. With that in mind, I can no longer contribute to Polygon to the best of my abilities. However, I am confident that the project’s leadership is fully committed to its success. I will always be cheering from the sidelines and supporting however I can.” 

Bjelic will resign from his roles on the Polygon Foundation board. Jaynti Kanani, Sandeep Nailwal, and Anurag Arjun founded Matic Network in 2017. The team later rebranded the project as Polygon. Polygon has gained a significant place in the blockchain ecosystem with its Ethereum Layer 2 solutions. Additionally, the platform has conducted significant R&D in zero-knowledge and proof-of-stake technologies. 

Polygon 2.0 and Token Transition: A New Step in Blockchain 

Polygon launched a significant token transition in late 2024 as part of its 2.0 roadmap. MATIC tokens were replaced with the new POL tokens at a 1:1 ratio. This change aimed to expand the use of the network’s native tokens across gas fees, staking, and infrastructure like AggLayer, making the Polygon network more functional and user-friendly. 

Bjelic’s departure is seen as a natural outcome of the token’s decentralization and changes in the governance structure. Nevertheless, Polygon continues its development process without slowing down. The team remains focused on technical innovations and pushing the boundaries of blockchain technology. With the support of the community and investors, token continues to strengthen its leadership position in Ethereum Layer 2 solutions. 

Lastly, POL is trading at approximately $0.237. This price is about 69% lower than its all-time high of $0.77 in December 2024. The 24-hour trading volume is approximately $142 million.

RPC Centralization Poses Risks

In a blog post shared on May 19, Buterin highlighted the dangers of over-reliance on Remote Procedure Call (RPC) providers. These services let wallets and apps interact with Ethereum without running a full node. However, Buterin warned that this convenience comes at a cost:

“A market dominated by a few RPC providers will face strong pressure to deplatform or censor users. Many RPC providers already exclude entire countries.”

Introducing “Partially Stateless Nodes”

To combat this, Buterin proposes the creation of partially stateless nodes, which allow users to run lightweight, privacy-friendly nodes that store only the necessary parts of Ethereum’s state.

As Ethereum’s gas limit increases and the blockchain expands, running a full node becomes increasingly resource-intensive. Partially stateless nodes aim to ease this burden by letting users store only personal account data, DeFi activity, and frequently used tokens such as stablecoins and ETH.

These new nodes would validate blocks statelessly, meaning they do not require the full Merkle tree or entire historical data. This makes it easier for individual users to operate secure nodes without needing enterprise-grade hardware.

Buterin also emphasized that reducing dependency on RPCs and supporting more personal nodes is crucial for maintaining Ethereum’s decentralization and censorship resistance.

According to a framework proposed by Ethereum co-founder Vitalik Buterin, Starknet has now reached “Stage 1” decentralization, marking a shift to limited governance and operational independence.

And the timing couldn’t be better — Starknet has also emerged as the largest ZK-rollup-based layer-2 network by total value locked (TVL).

Starknet Leads ZK-Rollups With $629 Million TVL

With a TVL of $629 million, Starknet now outpaces close competitor ZKsync, which holds $610 million, as reported by L2Beat. This positions Starknet at the forefront of ZK-rollup technologies in terms of locked value, making it a benchmark among zero-knowledge scaling solutions.

The project’s advancement to “Stage 1” decentralization was supported by technical measures like the implementation of a security council and censorship resistance mechanisms. Starknet has also adopted validity proofs, allowing cryptographic verification of all transactions via smart contracts — a core difference from the fraud-proof model used by Optimistic rollups.

Stage 2 In Sight, With Eyes On Bitcoin

StarkWare CEO Eli Ben-Sasson stated that the long-term vision is to reach “Stage 2” decentralization, where the network will be fully autonomous and community-driven. Only a few small layer-2 networks have achieved this so far.

Interestingly, Ben-Sasson also mentioned that Starknet’s ambitions extend to Bitcoin, suggesting parallel development on the world’s largest blockchain.

Currently, the entire layer-2 ecosystem holds around $44.2 billion in value, though it remains down 20% year-to-date. Base, Coinbase’s Optimistic rollup, leads the sector with $14.7 billion in locked assets, accounting for a 33% market share.

Sandeep Nailwal, Polygon’s co-founder, told:

“We’re onboarding massive partners and growing fast, but without compromising on decentralization or security. This partnership is about solving real-world problems through blockchain.“

Investment in ZK Technology for Scalability

Polygon is heavily investing in zero-knowledge (ZK) technology, which allows the ecosystem to scale without sacrificing trust, decentralization, or transparency. According to Nailwal, the goal is to make blockchain as smooth and intuitive as Web2, while retaining its core strengths.

Solving Real Problems for Real People

Nailwal emphasized that the diversity of India’s user base requires tailored use cases. Together with Jio, Polygon will develop solutions that resonate with real-world needs to gradually onboard users to the chain.

He also noted that blockchain can help combat deepfakes and misinformation, as users increasingly demand verifiable and trustworthy information.
