Sui deploys emergency upgrades after six-hour network outage
After last week’s major six-hour outage, the Sui network has implemented upgrades to its mainnet, deploying version V1.63.3, and upgrading the protocol to version 107. The Sui Network rolled out protocol upgrades that reportedly address the underlying issues that may have triggered the outage Cryptopolitan reported last week, which lasted about 6 hours and stalled about $1 billion in transactions. Upgrades to Sui’s protocol and mainnet improvements The upgrades primarily include fixes to validator consensus issues that prevented nodes from reaching agreement on rejected transactions, optimized transaction confirmation paths for better efficiency and reliability, ensuring the ability to achieve finality directly and disabling RPC interfaces used by validators for transaction signing and submitting aggregated validator signature transactions. The project’s team has also made plans for faster detection/recovery mechanisms, better tooling for its operators, and expanded testing of the consensus engine. The team’s focus will remain on enhancing resilience while preserving Sui’s strengths. What happened to the Sui Network? The Sui Network suffered a major outage on January 14, which halted transactions and froze over $1 billion in value on the network. The Sui Foundation acknowledged the problem at 3:24 pm UTC on X amid reassurances to the users that core developers were working on a fix. “The Sui network is now back and fully operational. Transactions are flowing normally. If you continue to experience issues, please refresh your app or browser window. Thanks for your patience,” the Foundation wrote on X, promising a full incident report in the days that followed. The team started looking into the problem about 30 minutes before they made the announcement, according to the Foundation. However, the network was not restored for nearly 6 hours afterward. The incident was reportedly caused by what the team called a consensus outage, which is a technical issue that prevented the blockchain from confirming transactions. It is the network’s second major outage since its origin The outage from last week was the second major one the Sui network has faced since it started operating in May 2023. The first real one happened in November 2024 and was linked to challenges that had accrued over time. The post-mortem the team later shared identified the root cause as an internal divergence in validator consensus processing, which they say was triggered by an edge-case bug in the consensus commit logic. Notably, it was not caused by an exploit, network congestion, or timing synchronization issues, and there was no rollback, nor were user funds lost in the process of fixing the issue, thanks to the network’s safety mechanism, which worked as it was designed. It is not the first high-speed blockchain to face these struggles. Networks like Solana have faced similar issues in the past, though Solana has since left those behind and has not had any outages in more than one year. This is thanks in part to emergency updates that have allowed validators to communicate more effectively and address critical issues rapidly. The smartest crypto minds already read our newsletter.

Vitalik Buterin Warns Ethereum Faces “Unwieldy Mess” — Demands Protocol Cleanup Now
Ethereum co-founder Vitalik Buterin is warning that Ethereum risks becoming an “unwieldy mess” unless developers begin actively simplifying the protocol instead of continuously adding new features. In a post published on X on Sunday, Buterin said Ethereum’s biggest threat is not competition but internal complexity. An important, and perenially underrated, aspect of "trustlessness", "passing the walkaway test" and "self-sovereignty" is protocol simplicity. Even if a protocol is super decentralized with hundreds of thousands of nodes, and it has 49% byzantine fault tolerance, and nodes fully… pic.twitter.com/kvzkg11M3c — vitalik.eth (@VitalikButerin) January 18, 2026 He argued that decentralization, trustlessness, and self-sovereignty lose their meaning if the protocol becomes so complex that only a small group of experts can understand or maintain it. His remarks come as Ethereum is simultaneously posting record transaction activity and historically low fees. Buterin Calls Out ‘Protocol Bloat’ in Ethereum’s Codebase Buterin noted that even a network with hundreds of thousands of nodes and strong fault tolerance fails its core mission if its codebase grows into multiple layers of advanced cryptography that few people can audit. At the center of his concern is what he describes as protocol bloat. Ethereum’s development process, he said, has historically favored adding features while rarely removing old ones, largely to preserve backward compatibility. Over time, this leads to a protocol that grows heavier, harder to reason about, and more fragile. Buterin warned that such complexity undermines security, raises the barrier for new client teams, and weakens Ethereum’s ability to survive if current core developers step away. To counter this trend, Buterin called for an explicit “simplification” or “garbage collection” function within Ethereum’s development process. He said simplification should focus on reducing total lines of code, minimizing reliance on complex cryptographic dependencies, and introducing stronger invariants that make client behavior more predictable. Buterin Outlines Plan to Strip Complexity From Ethereum He pointed to past changes such as the removal of the SELFDESTRUCT opcode and transaction gas caps as examples of how carefully chosen constraints can make the protocol easier to implement and safer to operate. Buterin also outlined larger-scale cleanup options, including moving rarely used or complex features out of the core protocol and into smart contracts. Under this approach, legacy transaction types, precompiles, and even the Ethereum Virtual Machine itself could eventually be demoted from mandatory protocol components, allowing new clients to focus on a simpler core. The broader goal, he said, is for Ethereum to pass what he calls the “walkaway test.” That means reaching a point where Ethereum’s value proposition remains intact even if active protocol development slows or stops. Ethereum’s Path Forward Draws Sharp Divide With Solana In a January 12 post, Buterin said Ethereum must be able to ossify if it chooses , with all essential features already in place. Vitalik Buterin declares 2026 the year Ethereum reverses centralization drift with technical shifts restoring self-sovereignty and trustlessness across nodes, wallets, and applications. #Ethereum #VitalikButerin https://t.co/IxoJdam8lj — Cryptonews.com (@cryptonews) January 17, 2026 These include quantum-resistant cryptography, a scalable architecture built around ZK-EVMs and PeerDAS, full account abstraction, a secure gas schedule, and a proof-of-stake system that can remain decentralized for decades. Buterin’s push for simplification has not gone unchallenged. On January 18, Solana co-founder Anatoly Yakovenko publicly rejected the idea of protocol ossification, arguing that blockchains must “never stop iterating” to remain useful. Yakovenko said Solana’s survival depends on continuous adaptation driven by developers whose livelihoods rely on the network, framing stagnation as a greater risk than complexity. His comments come amid significant technical progress on the network. Ethereum is currently processing close to 2.5 million transactions per day , while average gas fees have fallen to around $0.15. Ethereum is handling more transactions than at any point in its history while charging users some of the lowest fees seen in years. #Ethereum #ETH https://t.co/iRJ5gNsvVM — Cryptonews.com (@cryptonews) January 19, 2026 Recent upgrades, including the Fusaka hard fork and adjustments to blob parameters, have expanded capacity and reduced costs, largely through increased layer-2 usage. At the same time, Ethereum’s staking dynamics have turned sharply positive. The validator exit queue has dropped to zero , while entry queues have surged to multi-year highs, showing reduced sell pressure and rising confidence in Ether as a yield-bearing asset.

Ethereum Transactions Hit Record High as Fees Fall to Multi-Year Lows
Ethereum is handling more transactions than at any point in its history while charging users some of the lowest fees seen in years. Key Takeaways: Ethereum is processing record transaction volumes while gas fees have fallen to the lowest levels. Recent protocol upgrades and rising layer-2 usage have expanded capacity and eased pressure on mainnet fees. Stablecoin activity and growing staking participation signal renewed confidence in Ethereum. Data shows the seven-day moving average of transactions on Ethereum approaching 2.5 million, nearly double the level recorded a year ago. Activity has climbed steadily since mid-December, reversing a gradual slowdown that had persisted through much of the second half of 2025. Ethereum Gas Fees Fall to Lowest Levels in the Network’s Modern History At the same time, transaction costs have dropped sharply. Average gas fees are hovering around $0.15, marking the lowest level in Ethereum’s modern history. Estimates from Etherscan suggest some common actions, such as token swaps, have recently cost as little as $0.04. The pairing of record throughput and minimal fees stands in contrast to earlier cycles, when congestion routinely pushed costs beyond the reach of smaller users. The change follows a series of technical upgrades. Ethereum’s Fusaka hard fork, activated seven weeks ago, introduced Peer Data Availability Sampling and formalized a twice-yearly upgrade cadence. A subsequent update in January adjusted blob parameters, increasing capacity and lowering data costs for layer-2 rollups. Together, these changes have improved efficiency across the ecosystem. Fee pressure has also eased due to shifts in how Ethereum is used. The block gas limit was raised from 45 million to 60 million in late November, expanding execution capacity. ETH has 10x more TVL and 14x more stablecoin supply than Solana. SOL has 3x more active addresses and 110x more daily transactions than Ethereum.

SOL is the home… pic.twitter.com/cHC1KWhb2s — Simon Dedic (@sjdedic) January 18, 2026 Meanwhile, a growing share of activity has migrated to layer-2 networks, reducing demand for mainnet blockspace even as total transaction counts rise. Stablecoins are a major driver of the surge. Analysts at Standard Chartered recently estimated that stablecoin transfers now make up roughly 35% to 40% of all Ethereum transactions. Geoffrey Kendrick, the bank’s global head of digital asset research, has described 2026 as a pivotal year for Ethereum, pointing to its role as the primary settlement layer for onchain dollars. Staking trends reinforce the picture of renewed confidence. More than 36 million ETH is currently locked in staking contracts, accounting for about 30% of the circulating supply, according to ValidatorQueue data. The entry queue has climbed to levels not seen since mid-2023, while exit demand has nearly vanished. Buterin Says Ethereum Is Entering a New Phase Focused on User Autonomy Ethereum co-founder Vitalik Buterin has framed the moment as more than a technical milestone. In a recent post , he said the community is entering a phase focused on restoring personal autonomy and improving user experience, arguing that earlier compromises made in pursuit of adoption no longer need to define the network’s future. “2026 is the year that we take back lost ground in terms of self-sovereignty and trustlessness,” Buterin said in an X post. Together, record activity, falling fees, and rising participation suggest Ethereum is entering a new phase, one where scale no longer comes at the expense of accessibility.

“No Longer”: Vitalik Buterin Demands End to Ethereum’s Value Compromises
Ethereum co-founder Vitalik Buterin has declared 2026 the year Ethereum reclaims lost ground on self-sovereignty and trustlessness, calling for an end to every compromise the network has made in pursuit of mainstream adoption. In a lengthy post on X on Friday, Buterin outlined sweeping technical and philosophical shifts aimed at reversing a decade of centralization drift across nodes, wallets, applications, and block building. “ 2026 is the year that we take back lost ground in terms of self-sovereignty and trustlessness, ” Buterin wrote. The manifesto indicates Ethereum’s sharpest pivot yet away from convenience-driven design choices that diluted core values, framing the moment as existential for the network’s long-term legitimacy and expanded role in global infrastructure. 2026 is the year that we take back lost ground in terms of self-sovereignty and trustlessness. Some of what this practically means: Full nodes: thanks to ZK-EVM and BAL, it will once again become easier to locally run a node and verify the Ethereum chain on your own computer.… — vitalik.eth (@VitalikButerin) January 16, 2026 Technical Roadmap Targets Node Accessibility and Privacy Infrastructure Buterin’s plan centers on making full node operation practical again through zero-knowledge Ethereum Virtual Machines and Block Access Limits, reversing years of rising hardware requirements that pushed verification off personal computers. “ Full nodes: thanks to ZK-EVM and BAL, it will once again become easier to locally run a node and verify the Ethereum chain on your own computer, ” he stated. The roadmap also prioritizes Helios to “ actually verify the data you’re receiving from RPCs instead of blindly trusting it, ” alongside oblivious RAM and private information retrieval protocols enabling users to “ ask for data from RPCs without revealing which data you’re asking, so you can access dapps without your access patterns being sold off to dozens of third parties all around the world. “ Social recovery wallets with timelocks will provide “ wallets that don’t make you lose all your money if you misplace your seedphrase, or if an online or offline attacker extracts your seedphrase, and also don’t make all your money backdoored by Google. ” Privacy features will integrate directly into wallet interfaces to “ make private payments from your wallet, with the same user experience as making public payments. “ Application interfaces will shift toward onchain hosting via IPFS to avoid “ relying on trusted servers that would lock you our of practical recovery of your assets if they went offline, and would give you a hijacked UI that steals your funds if they get hacked for even a millisecond. ” Buterin warned that “ over the last ten years we have seen serious backsliding in Ethereum, ” with nodes going “ from easy to run to hard to run ” and dapps shifting “ from static pages to complicated behemoths that leak all your data to a dozen servers. “ Long-Term Vision Beyond Immediate Protocol Upgrades Buterin acknowledged the transformation will not arrive quickly but emphasized its necessity. “ Every compromise of values that Ethereum has made up to this point – every moment where you might have been thinking, is it really worth diluting ourselves so much in the name of mainstream adoption – we are making that compromise no longer, ” he declared. “ It will be a long road. We will not get everything we want in the next Kohaku release, or the next hard fork, or the hard fork after that. But it will make Ethereum into an ecosystem that deserves not only its current place in the universe, but a much greater one, ” Buterin wrote. He concluded that “ In the world computer, there is no centralized overlord. There is no single point of failure. There is only love. “ Vitalik Buterin says Ethereum solved blockchain's trilemma with ZKEVMs and PeerDAS technology now running on mainnet after decade-long development. #Ethereum #Buterin https://t.co/cUzlhhO6Xr — Cryptonews.com (@cryptonews) January 4, 2026 The manifesto comes as Ethereum achieves breakthroughs on the blockchain trilemma through ZKEVMs and PeerDAS technology . The network has activated its second Blob Parameter-Only hard fork, raising the blob limit from 15 to 21 and expanding data capacity to support rollup scaling while maintaining low base-layer fees. Network growth has also accelerated sharply , with new active addresses climbing from just over 4 million to around 8 million in the past month and daily transactions hitting a record 2.8 million, roughly 125% higher than year-earlier levels. Glassnode data shows that month-over-month activity retention has nearly doubled in the newest user cohort, indicating that new participants are staying engaged rather than churning after initial interactions.

Buterin says 2026 will mark Ethereum’s push to reclaim privacy
Ethereum co‑founder Vitalik Buterin has proclaimed 2026 as the year the network will actively reverse what he describes as a decade of “backsliding” in self‑sovereignty, decentralization, and privacy. Buterin made the declaration in a social media post on X (formerly Twitter), stating that the Ethereum community will focus on reclaiming user autonomy and trustlessness that have eroded over time due to design trade‑offs in pursuit of mainstream adoption. “2026 is the year that we take back lost ground in terms of self‑sovereignty and trustlessness,” Buterin wrote, signaling a renewed emphasis on empowering users over third‑party intermediaries He added that the transformation will take time to materialize fully, noting that not all goals will be achieved in the next Kohaku release or even in subsequent hard forks. Nevertheless, he argued that the gradual progress will ultimately shape Ethereum into an ecosystem worthy not only of its current standing, but of a far greater role in the broader blockchain landscape. Vitalik says they hope to introduce social recovery wallets and timelocks Over recent years, Ethereum’s developers have quietly put the pieces in place for the needed enhancements. For starters, earlier this year, the Ethereum founder had noted that the ZK-EVM had progressed to alpha status, achieved production-level benchmarks, and shifted its focus to security. In his latest post, he explained that the network will now prioritize a setup that allows users to run nodes locally and independently verify the chain using ZK-EVM and BAL. He also asserted that users on the network can move away from trusting RPCs by default and toward actively verifying the data they deliver. Additionally, he shared that their plan to improve the user experience includes introducing social recovery wallets and timelocks — wallets that prevent losing everything if a seed phrase is lost. Buterin has backed social recovery wallets since at least 2021, and that vision began taking shape last year with the launch of EIP-7702 in Ethereum’s Pectra upgrade. In the last few months, he has also been increasingly vocal about the importance of privacy at both the user and protocol level. In a Friday post, he said privacy-focused design should let users send private payments as easily as standard transactions. So far, even the Foundation has stepped up its privacy agenda, refocusing internal teams and initiating development of the Kohaku wallet framework. It also introduced ERC-4337 and FOCIL, which could enhance the system’s resistance to censorship. Buterin also emphasized that users should be able to access dapps without relying on servers that might become unavailable or compromised. Buterin stressed the need for quantum-resistant cryptography On Monday, the Ethereum founder also stressed the urgent need to implement quantum-resistant cryptography for long-term security. In his earlier post, Buterin expressed his concerns about delaying quantum resistance for the sake of efficiency. He stressed that Ethereum should be able to pass the walkaway test, underlining its purpose as a home for trust-minimized apps. He also outlined the network’s main goals: ensuring complete quantum security quickly; building a scalable system for ZK-EVM and PeerDAS; maintaining a sustainable state model; implementing full account abstraction; designing a DoS-resistant gas pricing system; creating a durable decentralized PoS model; and developing a censorship-resistant block-building method. He argued that completing these infrastructure enhancements over the coming years would be essential for Ethereum’s enduring technological and community strength. He further noted, “Being able to say ‘Ethereum’s protocol, as it stands today, is cryptographically safe for a hundred years’ is something we should strive to get to as soon as possible.” Before, the crypto mogul had also insisted that the network should focus more on decentralization and resilience over efficiency and convenience.
