Ethereum’s Fast L1 Vision: Vitalik Buterin Unveils Strawmap Plan for Slots and Finality

TLDR:

    • Vitalik proposes cutting Ethereum’s slot time from 12 seconds to 2 seconds using a sqrt(2) formula.
    • Erasure coding upgrades to Ethereum’s p2p layer will reduce block propagation time across the network.
    • The Minimmit finality algorithm targets a reduction from 16 minutes today down to just 8 seconds.
    • Ethereum’s quantum-resistant upgrades will roll out in phases, with slot protection arriving first. 

Ethereum’s Fast L1 goal took center stage as Vitalik Buterin published a detailed strawman roadmap outlining how the network plans to evolve its base layer.

The document covers slot time reductions, peer-to-peer network upgrades, and a new finality algorithm. Buterin walks through each goal methodically, explaining how the changes interconnect.

The roadmap presents a phased, component-by-component transformation of Ethereum’s consensus layer toward a faster, simpler, and quantum-resistant design.

Slot Time and Network Architecture at the Core of Fast L1

Ethereum’s Fast L1 goal begins with a structured reduction of slot time across multiple incremental steps. Buterin proposes moving from the current 12 seconds down through 8, 6, 4, 3, and eventually 2 seconds per slot.

Each reduction follows a “sqrt(2) at a time” formula, with steps only taken when safety is confirmed.

Supporting shorter slots requires major improvements at the network layer. Buterin points to ongoing work by @raulvk on an optimized peer-to-peer design using erasure coding.

The new architecture splits each block into pieces so that any subset of them is enough to reconstruct the full block.

In his post, Buterin explained: “split each block into 8 pieces so that with any 4 of them you can reconstruct the full block.” This design cuts 95th percentile block propagation time and makes shorter slots viable without security tradeoffs.

That said, adding protocols like ePBS and FOCIL to the slot structure tightens timing constraints. These changes shrink the safe latency window from one-third of a slot to one-fifth.

To offset this, researchers are exploring a model where only 256 to 1,024 randomly selected attesters sign per slot, eliminating the aggregation phase and shortening slot duration further.

Finality Overhaul and the Shift to Quantum-Resistant Consensus

Beyond slot time, the strawman roadmap targets a complete rework of how Ethereum achieves finality. Today, finality takes roughly 16 minutes on average, calculated across 12-second slots, 32-slot epochs, and 2.5 epochs. Buterin wants to decouple finality from slot time entirely so each can be optimized on its own path.

The target is a one-round-finality algorithm called Minimmit, a variant of the established BFT consensus design. A projected trajectory moves from 16 minutes today through several intermediate stages, eventually reaching as low as 8 seconds with aggressive Minimmit parameters.

These changes will also carry a transition to post-quantum cryptography, including hash-based signatures and a STARK-friendly hash function.

Three hash function options are under active research: adjusting Poseidon2’s round count, returning to Poseidon1, or adopting BLAKE3 as a conventional alternative.

Buterin described the overall transformation as a “ship of Theseus” style process, replacing each part of Ethereum’s consensus layer one at a time.

Notably, the phased approach means slot-level quantum resistance could arrive well ahead of finality-level protection, providing an early security layer if quantum computing advances faster than anticipated.

DeFi exploiter targets lending protocols with oracle tricks

DeFi exploiter targets lending protocols with oracle tricks

A serial hacker is targeting DeFi lending protocols, with approximately $3.5 million stolen so far. In the latest incident, they exploited an oracle misconfiguration in lending platform Ploutos Money, leading to a loss of almost $400,000.

Crypto security firm CertiK noted that the project appears to have deleted its website and social media presence.

According to analysis by blockchain auditor BlockSec, Ploutos Money used Chainlink’s bitcoin (BTC)/USD feed as an oracle for USDC price. “The attacker was able to borrow 187 ether (ETH) by posting only eight USDC as collateral,” the post explains.

BlockSec also points to the timing of the exploit, just one block after the misconfiguration was confirmed. While the firm suggests “the attacker closely monitored and acted on the configuration change,” many of the replies to CertiK and BlockSec’s posts suspect insider involvement.

Pseudonymous blockchain investigator Tanuki42 linked the exploiter to at least four other hacks, including two million-dollar losses for Moonwell.

Last week, Moonwell was left with $1.8 million of bad debt when a misconfigured oracle returned a cbETH price of $1.12 instead of approximately $2,200. The code change which caused the loss had been co-authored by Claude Opus 4.6, alongside a Moonwell contributor.

The (bad) luck of the draw

Also today, in an apparently unconnected attack, Ethereum-based “private ZK lottery,” FOOM CASH, lost $1.6 million when its “broken ZK verifier” was compromised.

According to blockchain security firm QuillAudits, the project lost $1.3 million on Ethereum and $316,000 on Base. The firm’s analysis explains that the project’s use of its ZK verifier was flawed.

In setting two constants to the same value, “anyone can compute it [the verification equation], no secret needed.”

A similar attack affected Veil.Cash, a privacy protocol on Base, last week. However, losses were small at only 4.5 ETH, of which 2 ETH were recovered by white hats Decurity.

Why XRP Spot Buying Is Skyrocketing While Futures Open Interest Slumps

Published

on

XRP Leads Altcoin Inflows While Bitcoin Investment Products Struggle


Bitrue reported a 212% surge in spot buying for XRP on February 26, with buy orders more than doubling sell pressure.

Bitrue said on February 26 that it recorded a 212% jump in XRP spot buying as institutional investors continued allocating capital through newly launched XRP exchange-traded funds (ETFs).

The exchange linked the spike to roughly $1.1 billion in cumulative ETF inflows, arguing that steady demand from funds and retail traders could tighten available supply in the months ahead.

Spot Buying Jumps as ETF Inflows Build

In a post on X, Bitrue said XRP buy orders on its platform outpaced sell orders by more than two to one.

“We recorded a 212% increase in XRP spot purchase volumes, outpacing the sell side by over 2x,” the exchange posted on X.

It attributed the imbalance to sustained institutional accumulation since the debut of XRP ETFs, which it claims have drawn $1.1 billion in net assets, even though data from SoSoValue showed there have been muted ETF flows in recent days.

However, the derivatives market tells a different story. According to CryptoQuant, XRP futures open interest has fallen across major platforms over the past 90 days, with Binance recording a decrease of 7.7 million XRP and Bybit showing a larger reduction of around 12 million tokens. Furthermore, the three-month moving average for XRP futures volume has dropped to its lowest level since November 2024, settling at approximately $87 billion.

Looking at XRP’s broader market structure, it was trading around $1.44 at the time of writing, up nearly 5% in the last 24 hours and about 2% during the week. Even so, the token is still down more than 23% over the past month and almost 38% across the past year, far below its July 2025 all-time high of $3.65.

Cooling Leverage Meets Steady Spot Demand

The divergence between spot accumulation and falling derivatives activity suggests a shift in market composition rather than uniform bullish momentum. Open interest now stands near $2.37 billion per CoinGlass figures, and the contraction in leveraged positions may reflect traders reducing risk after months of volatility.

From a price standpoint, XRP remains range-bound between $1.38 and $1.48 over the past 24 hours. One market watcher, CasiTrades, flagged resistance around $1.40 and $1.65, with support near $1.11 and $0.87. According to them, a sustained move above those resistance levels would likely require stronger follow-through from ETF inflows and broader market participation.

As such, considering the broader data, Bitrue’s reported spike in spot buying highlights firm exchange-level demand, but the wider data show a market that is rebalancing rather than accelerating.

Nonetheless, the crypto exchange is predicting that growing retail and corporate support could lead to a supply deficit that may push up the Ripple token’s performance enough to beat major rivals this year.

“With support increasing from retail and institutional levels, Bitrue is forecasting a potential supply squeeze, which will likely result in XRP outperforming key competitors over Q2 2026,” wrote Bitrue.

Ether Hits $2.1K But Holding It Requires Two Factors

Ether (ETH) price reached a weekly high of $2,150 on Thursday, which is a key level for large ETH holders, but volatility in the crypto and stock markets continues to catalyze corrections below $2,000.

A daily close above $2,100 remains important because that level aligns with the cost basis and realized price of wallets holding 100,000 or more ETH. Realized price tracks the last moved price of coins, offering a profitability gauge rather than a spot reference.

Since 2020, Ether has traded below this whale cohort’s realized price only a handful of times, most notably during the 2022 bear market. The chart shows that the price has regularly recovered after the realized price level was tested as support.

Futures market analyst Dom described the setup as “a good clean look for the whole market,” pointing to an early-week sweep near the range lows. Dom said that the price tapped the one-month rolling VWAP (volume-weighted average price) and the value area high, the upper boundary of the price range where most of the volume traded over the past month.

The VWAP measures the average traded price weighted by volume. Acceptance over $2,140 may mark a shift in short-term order flow, while failure to retain a higher level keeps the price inside the established range.

$1,800 remains the key price level to watch

CoinGlass data highlighted short liquidations of over $220 million over the past two days, clearing overhead leverage. Now, roughly $2.66 billion in cumulative long liquidation exposure sits near $1,800, forming a liquidity pocket below the price.

Crypto analyst Pelin Ay pointed to a notable shift in funding rates on Binance. ETH funding flipped sharply negative earlier this month as aggressive short positions piled in alongside Ether price weakness. Following Tuesday’s drop below $1,800, the funding rate has since swung back into positive territory at 0.23%, a sign that late shorts were squeezed out of their positions.

However, with the funding rate now elevated, traders’ positioning appears to be tilting toward the long side. If this trade becomes overcrowded, it raises the risk of a potential long squeeze near the $1,800 level once again, especially if the price momentum stalls or reverses.

Market analyst IncomeSharks identified three technical hurdles, including repeat super trend rejections and a channel resistance near $2,250.

The SuperTrend uses volatility, measured by the average true range (ATR), to define the trend direction. When the price trades below the indicator, the line flips red and acts as dynamic resistance. On the chart above, each rebound has been rejected at the red band, signaling that sellers remain in control.

The analyst added that traders should watch whether Ether revisits or finds renewed buying interest near the April lows around $1,500, a level that resides between a weekly demand zone of $1,691 and $1,384, before any sustained move above $2,500 can take shape.
