Vitalik Calls for ‘Cypherpunk Principled Non-Ugly Ethereum’ as Bolt-On Upgrade

TheNewsCryptoPublished on 2026-02-21Last updated on 2026-02-21

Abstract

Vitalik Buterin has outlined his vision for Ethereum evolution, rejecting the idea of abandoning the current chain. Instead, he proposes a "cypherpunk principled non-ugly Ethereum" as a tightly integrated "bolt-on" upgrade. This enhancement aims to create a simpler, more privacy-focused framework with stronger censorship resistance, zero-knowledge proof compatibility, and a simpler consensus mechanism. It would allow smart contracts to be rewritten in a more elegant, verifiable language using AI tools. Buterin expressed confidence in Ethereum's ability to undergo significant in-flight upgrades. This aligns with the Ethereum Foundation's 2026 priorities, which focus on scaling, improving user experience, and hardening the chain, including measures like Fork-Choice Enforced Inclusion Lists (FOCIL) and post-quantum readiness.

Ethereum’s next chapter is envisioned by Vitalik, which is a ‘cypherpunk upgrade’ and not as a replacement chain, but as a tightly integrated evolution of the existing system.

On February 20, Vitalik Buterin mentioned his ambitious vision for Ethereum in a response to an X post, which said, “Vitalik should let the original ethereum die a slow and painful death by fragmentation (tempo, reth, l2s, app chains, institutions, etc) and rebuild it as a cypherpunk chain from first principles on risc v just to show who was the boss.”

Building on Ethereum, Not a New Chain

Buterin had dismissed the idea of abandoning the current Ethereum network due to issues such as fragmentation caused by layer-2 solutions and institutional influence. Rather, he proposed building a “cypherpunk principled non-ugly Ethereum” as a tightly integrated “bolt-on” addition to the existing system.

Which means, he aims to build a simpler version, a more privacy-focused framework that interoperates with today’s Ethereum by adding more features, such as stronger censorship resistance, zero-knowledge proof compatibility, and simpler consensus.

Buterin also said that this newly set system can allow smart contracts to be rewritten in a more elegant, verifiable language, using AI tools, that potentially reshapes how developers and users interact with Ethereum in the next five years.

Further, Buterin echoed the confidence by saying, “Ethereum has already made jet engine changes in-flight once (the merge), we can do it ~4 times more!”

Strengthening Ethereum for 2026

Previously, the Ethereum Foundation released its protocol priorities for the year 2026, in which they mentioned there are three new tracks to be focussed such as scaling, improving UX, and hardening the chain. With that, on Thursday, Buterin wrote about Fork-Choice Enforced Inclusion Lists (FOCIL) as a major step toward strengthening Ethereum.

Also, on Friday, Buterin wrote that the 2026 upgrade includes network security testing, post-quantum readiness, and mentioned. “Ethereum will emerge from the year a far stronger, more powerful, and more self-sovereign protocol than what it was entering this year.”

Michael Saylor Claims It Has Become Impossible to Implement the Bitcoin Update He Opposed!

Michael Saylor stated that it has become mathematically impossible for BIP-110 to achieve its required 55% voluntary support threshold within the current Bitcoin mining difficulty adjustment cycle. According to his analysis of 946 blocks generated up to block 960,561, only 24 blocks included a version field signal supporting BIP-110. Saylor noted that all these signaling blocks were mined by DATUM miners sharing rewards through the OCEAN pool, with no supporting signals from miners outside OCEAN. He concluded that BIP-110 will not reach the 55% level in this cycle and argued the current signals do not represent a broad miner consensus. BIP-110 is a proposal aimed at making it harder to embed large non-financial data, like images or text, into the Bitcoin blockchain, promoting a view that Bitcoin should be used primarily for monetary transactions. Saylor opposes this, arguing the Bitcoin network should not arbitrate which transactions are necessary and that rules should not change based on the preferences of a few. He also contends that high support metrics may be inflated by automated signaling software rather than reflecting genuine miner support.

Within Strategy's Framework, STRC's Dividend Yield Remains at 12% as Share Price Stays Below Par Value

Michael Saylor, Executive Chairman of Strategy (MSTR), confirmed that the dividend rate for its STRC perpetual preferred shares will remain at 12.00% through August 2026. The rate has increased from 9% at its July 2025 launch to the current high via a "ratchet" mechanism, which permanently raises the rate by 0.5% whenever the share price falls below $95. This mechanism is intended to push the price back toward its $100 par value and support Strategy's "at-the-market" (ATM) program for issuing new shares to fund Bitcoin purchases. However, the mechanism has not worked as intended. STRC shares closed at $89.46 on July 31, remaining about 10-11% below par value despite the record-high dividend. Competition from rival Strive's higher-yielding SATA securities has pressured demand. The persistent discount has forced Strategy to suspend new STRC issuances via its ATM program, limiting this funding channel for Bitcoin acquisitions. STRC's struggles reflect Bitcoin's own volatility, as the preferred shares historically move in tandem. Analysts have warned the ratchet structure carries long-term, one-way risk. A law firm is investigating Strategy's ability to maintain dividend payments if Bitcoin's price stays low. Retail investors own roughly 83% of outstanding STRC shares, a group seen as prone to panic selling during downturns. In response, Strategy has established financial reserves, including a liquidity cushion covering about 26 months of dividend/interest obligations, and a $2 billion share buyback program alongside a Bitcoin monetization framework, though the company emphasized it is not obligated to sell any Bitcoin.

Analyst: Bitcoin's Price Will Drop to $60k in August, Then Rebound to $70k

Financial analyst Andrey Poroshin has provided a new forecast for Bitcoin's price dynamics in August. Poroshin, an analyst at the Bitbanker exchange, expects the cryptocurrency market to experience a downturn this month, with prices retesting the $60,000 level due to a lack of supportive macroeconomic catalysts. He noted that the recent US Federal Reserve decision to hold interest rates did not significantly impact the market, while inflation remains above the 2% target. Poroshin stated that Bitcoin is ending July under pressure from moderate volatility and a lack of new macroeconomic stimuli, leading to continued market caution. According to his base scenario, Bitcoin will drop to a range of $60,000 to $62,000 before recovering to $70,000. He pointed out that even $70,000 remains below the cost of mining in the US, which has prompted some miners to shift towards AI data center operations. Poroshin cited the winding down of BitMEX's operations as a potential catalyst for a price rebound, suggesting the exit of weaker players often coincides with market reversals and reduced short-term selling pressure. He believes Bitcoin is currently less susceptible to geopolitical shocks, such as the Iran-US conflict, and does not expect significant market changes in August related to the pending CLARITY Act. Looking ahead, Poroshin forecasts that September will bring more active price fluctuations driven by potential Fed rate decisions and possible discussions or approval of the CLARITY Act.

Following the Coldcard Hack, One of the Largest Bitcoin Wallet Hacks Recently, a New Wave of Losses Begins! Losses Are Mounting

Following a major hack targeting Coldcard hardware wallets, losses have surged to approximately 1,367 BTC ($88.6 million) across 4,585 addresses. The third wave of attacks stole an additional 207.7 BTC, exhibiting different patterns from the first two. While initial attacks used shared deposit addresses and targeted P2WPKH wallets, the latest wave employed unique recipient addresses per victim and focused on P2WSH addresses. Analysis by Galaxy Research cannot definitively link all three waves to the same attacker, raising the possibility of a second actor exploiting the known vulnerability. The stolen funds, predominantly from wallets holding under 1 BTC, remain unspent. The vulnerable Coldcard firmware was released in March 2021, and all stolen coins originate from after that date.
