Base Shifts From OP Stack to Unified Stack for Next Phase of Upgrades

TheNewsCryptoPublicado em 2026-02-19Última atualização em 2026-02-19

Resumo

Base, a Coinbase-incubated Ethereum layer-2 blockchain, is transitioning from the OP Stack to its own unified software stack called "base/base" to accelerate upgrades and enhance security. While moving away from the OP Stack, Base will continue to receive support from the Optimism Foundation and remain compatible with OP Stack specifications. The new stack, built on open-source components like Reth, simplifies the architecture, making the network easier to update while maintaining safety and decentralization. Base remains a Stage 1 decentralized rollup and is strengthening security with an independent signer, faster withdrawals, improved governance, and stronger protections. The roadmap includes multiple hard forks: Base V1 will implement Ethereum’s Fusaka upgrades and transition to TEE/ZK proofs, while future forks (V2 and V3) aim to improve user interactions and add Ethereum’s Glamsterdam support. Node operators are advised to switch to the new base client for compatibility with upcoming upgrades.

Base, a Coinbase-incubated Ethereum layer-2 blockchain, was launched as an OP Stack chain, then incorporated a diverse range of software in collaboration with various partners, including Optimism, Flashbots, and Paradigm.

According to the Base announcement, they introduced a single unified stack called base/base for accelerating upgrades and additional security, and it is made public and opened for contribution. While moving away from the OP Stack, it will still receive mission-critical support from the Optimism Foundation.

Simplifying the Stack to Accelerate Upgrades

According to the Base engineering blog, “Our unified solution, base/base, built on open-sourced components such as Reth, allows us to dramatically simplify the number of components, by optimizing them directly for our use case.” This will make the network easier to update and allow the developers to focus on what Base specifically needs, as it is open and public.

As Base is upgrading how it works to become more independent and efficient. Importantly, nothing changes in terms of safety. Base remains a Stage 1 decentralized rollup, and the team is also strengthening security by adding an independent signer and speeding up plans for faster withdrawals, improved governance, and stronger protections to keep the network open, neutral, and secure for everyone.

Base’s Long-Term Roadmap

As of now, Base blog noted, “Base will continue operating as it does today, and we will remain compatible with the OP Stack specification.”

The upcoming hard fork (Base V1) is going to implement Ethereum’s Fusaka upgrades and transition from Optimistic proofs to TEE/ZK proofs for a faster network. Further, two more hard forks are discussed, such as the Base V2 hard fork, which is planned to introduce smoother user interactions. Then, Base V3 hard fork is planned to add Ethereum’s Glamsterdam Support.

As the shift marks a broader architectural consolidation across Base’s evolution, from its initial OP Stack foundations to a unified stack fully maintained within Base, the Base network asks node operators to use the new base for client updates instead of Optimism’s to remain compatible with upcoming future hard forks.

VCs on 2025 Crypto Investments: 84% of 118 Tokens Break Issue Price, Only One Type of Company is Quietly Making Money

Crypto investor Ching Tseng categorizes the market into four quadrants based on two axes: crypto-native vs. traditional finance (TradFi)-oriented, and having traction vs. no traction. In 2025, 84.7% of 118 tracked token launches fell below their issuance price, with a median fully diluted valuation drop of 71%. Crypto-native projects without traction are experiencing massive capital destruction, often relying on speculative narratives without sustainable revenue or user retention. Crypto-native teams with traction, often built in prior cycles, generate real revenue but face structural challenges with their tokens lacking direct value capture mechanisms. While some have implemented successful buyback programs, the core issue remains finding growth beyond crypto volatility. TradFi-oriented startups without traction face long, costly enterprise sales cycles but benefit from a robust M&A environment, with crypto acquisitions reaching a record $8.6 billion in 2025. The current winners are TradFi-oriented companies with traction, particularly in the Real World Asset (RWA) tokenization space, which grew from $5.5B to $18.6B in 2025. They are winning through enterprise sales, building alliances, and improving unit economics on established compliance stacks. Their main risk is being bypassed by large incumbent institutions building their own infrastructure. The overarching theme is market maturation, where narrative alone is insufficient for long-term success.

Crypto Trader's Account: Friends Are Leaving, What's Left to Do in This Industry?

Crypto trader Donn reflects on the declining state of the cryptocurrency industry, noting that many peers are leaving due to three core challenges: lack of innovation in the past 2-3 years, the threat of quantum computing to Bitcoin by 2029, and increased DeFi attacks exacerbated by AI models like Claude Mythos. VC activity has stagnated, with few quality token projects generating over $50M in annual income. Liquidity and investor interest have dwindled, shifting focus to traditional markets. For traders, event-based strategies remain viable but are increasingly competitive and low-yield due to reduced open interest and retail participation. Systematic and basis traders are exploring alternative strategies as traditional methods become less profitable. DeFi yield farming is increasingly unattractive due to rising hack risks and insufficient returns, pushing farmers toward off-chain options. On-chain gem hunters still chase high-risk, high-reward opportunities, but success rates are low, and most tokens crash shortly after peaking. Personally, the author is scaling down crypto trading, maintaining a small arbitrage strategy on Polymarket, and exploring AI automation for analytical tasks. He is also researching AI model fine-tuning and broader AI applications beyond crypto, seeking new focus areas as the industry wanes.

To Counter Chinese Models, Silicon Valley's Big Three Even Formed an 'Avengers Alliance'?

In a rare move, Silicon Valley's AI giants—OpenAI, Anthropic, and Google—have formed a coalition called the "Frontier Model Forum" to combat what they term "adversarial distillation." This practice involves companies, particularly Chinese firms like DeepSeek, Moon Dark Side, and MiniMax, allegedly using massive API interactions to extract and replicate the capabilities of advanced models. Anthropic's report claims these firms engaged in over 16 million interactions, copying logic, reasoning chains, and model behaviors to train their own systems at lower costs. While distillation is a known technique, the alliance argues it threatens both commercial interests and safety, as distilled models may bypass critical risk assessments. However, the accusations are met with skepticism, citing hypocrisy, as these giants themselves face lawsuits over unauthorized data scraping. The debate highlights the unresolved ethical and legal gray areas in AI development.

XRP Ledger Gains Ground, Surpassing Solana In RWA Space – Pundit Shares

The XRP Ledger (XRPL) is gaining significant traction in the cryptocurrency sector, particularly in the real-world asset (RWA) tokenization space, where it has surpassed Solana. With nearly $1.9 billion in tokenized assets, XRPL is positioning itself as a leading network for efficient, affordable, and scalable blockchain integration with traditional assets. A key development is the new TokenEscrow feature, which enables secure holding and release of tokenized assets. According to experts, this amendment, combined with Flare Networks' compute layer, enhances privacy and compliance for RWAs, signaling strong institutional momentum rather than speculative interest. Additionally, Ripple Labs has announced a multi-phase plan to make the XRP Ledger quantum-ready by 2028, addressing potential future threats from quantum computing to blockchain cryptography. The strategy involves post-quantum recovery, proactive planning, exploration of new cryptographic primitives, and a full transition to quantum-resistant signatures.

Warsh Hearing Firmly States: Will Never Be Trump's 'Puppet', Vows to Uphold Federal Reserve Independence

In a Senate Banking Committee hearing on his nomination as Federal Reserve Chair, Kevin Warsh strongly emphasized the Fed's independence, vowing he would "absolutely not" be a "puppet" for former President Trump. He stated that Trump never asked for, and he would never have given, any promise to cut interest rates. Warsh outlined plans for significant reforms at the Fed, including a new inflation framework, less frequent communication from officials, and a gradual reduction of its $6.7 trillion balance sheet. He argued the Fed's recent struggles were self-inflicted and that its large balance sheet had exacerbated wealth inequality ("K-shaped" economy). While not explicitly calling for rate cuts, Warsh suggested AI could boost productivity and create room for them, though he acknowledged its short-term inflationary risks. He also supported integrating digital assets into the financial system but opposed a Fed-issued CBDC. A key obstacle to his confirmation remains Senator Tillis, who vowed to block the nomination until a Justice Department investigation into Chair Powell is resolved.
