Solana cuts blockchain slot time to 350 milliseconds

Abstract

Solana has reduced its blockchain slot time to 350 milliseconds, the first reduction since the network's launch. According to Solana Foundation VP of Technology Jacob Creech, this marks a "new era" with a next target of 300ms. Average slot times are currently 360ms, down from the original 400ms target. The reduction is part of a broader plan to eventually cut slot times to 200ms to improve network latency and confirmation speed. This initial cut is the first of four planned 50ms reductions. The changes, formalized in the approved SIMD-0525 proposal, are slated for implementation in the upcoming Agave v4.2 validator client, though the schedule remains tentative.

Solana reduced its slot time to 350 milliseconds, marking the first such reduction since the inception of the network, according to the Solana Foundation’s vice president of technology, Jacob Creech.

“We’re in a new era of 350ms. Next stop, 300ms,” Creech said in a Friday X post.

Average slot times on Solana stood at 360ms at press time, down from the network’s original 400ms target, according to the Solana slot time explorer.

In June, the Solana Foundation shared plans to reduce slot times from 400ms to 200ms, arguing that it would improve latency and accelerate confirmations on the blockchain network. Three further 50ms reductions are planned.

All four stages are targeted for mainnet activation in Agave v4.2, a validator client developed by Anza, though the schedule is tentative.

SIMD-0525, the proposal establishing the shorter slot times, was approved and merged on May 14.

Bitcoin Soars by $10,000 in a Week, Short Sellers Lose $3 Billion

Bitcoin surged by over $10,000 in a week, surpassing $70,000 for the first time since May, as short-sellers lost approximately $3 billion in 24 hours in the largest short squeeze since 2021. The rally was triggered primarily by the US Treasury's announcement to double its long-term bond buyback operations to support market liquidity, a move interpreted as a signal of potential monetary easing. This led to a drop in long-term Treasury yields and prompted traders to seek Bitcoin as a hedge. The price breakout accelerated automated liquidations of short positions that had accumulated during a prior six-week trading range. The surge coincided with renewed regulatory momentum, including President Trump's call for Congress to pass the CLARITY Act and a White House meeting with crypto industry leaders, reinforcing perceptions of a more favorable political environment. Major stock indices mostly rose in response to the Treasury's announcement, while Bitcoin's momentum indicators strengthened. The move marks a potential return to the $80,000 level last seen in May.

Zcash, Bitcoin Cash, and Cardano Show Gains, with ZEC Leading the Way with a 47% Surge

In the last 24 hours, several altcoins saw significant gains. Zcash (ZEC) led the rally, surging 47.1% to $836 before consolidating around $810, driven by privacy focus and developments around a potential Grayscale spot ETF conversion. Bitcoin Cash (BCH) rose 31.4% to $299.49. Other notable gainers included Cardano (ADA), up 19% to $0.2563, Dogecoin (DOGE), and Whitebit (WBT), each up 17.7%. The rally extended to Stellar (XLM), Chainlink (LINK), and Hyperliquid (HYPE), which rose 11.9% to $81.50, buoyed by DEX volume and a token buyback mechanism. The broad-based momentum is attributed to renewed U.S. regulatory optimism, including President Trump's support for the Digital Asset Market Transparency Act, and expanded Treasury bond buybacks, which lowered yields and freed liquidity for risk assets. Analysts note the rally was accompanied by high trading volumes and leverage, which could amplify volatility. Market participants are watching for tangible progress on crypto market structure legislation in the coming weeks to sustain the uptrend.

Changes in reward and commission systems on cryptocurrency exchanges should be expected due to strategy shifts

As the bear market continued in Q2, leading crypto exchanges Coinbase, Bullish, and Gemini reported declines in trading revenue. In response, they are shifting strategies toward newer products like stablecoins and prediction markets, which is expected to change their reward and commission structures. Coinbase is focusing on its USD Coin (USDC) offerings, with average balances surging 44% to $20 billion, and has cut costs to fund increased USDC rewards. Gemini is tripling down on prediction markets, adding market makers and offering user rebates, though related revenue grew only 18% despite a near-doubling in bets. Bullish, targeting professional traders, launched a new rewards program. While its adjusted transaction revenue fell 21% quarterly, it was still up 24% year-over-year—the only exchange of the three to achieve annual growth. Despite falling trading volumes, commission economics improved for some, like Gemini, even as its overall revenue dropped. If the crypto price rally continues and ends the bear market, trading revenues could recover. However, as exchanges try to reduce dependence on market volatility, users can expect more rewards and incentives for using new products. Competition over fees may also intensify. The blurring lines between crypto and traditional finance platforms could further drive this competition, potentially benefiting retail traders and investors.

Zcash Surged 48% and Surpassed $800. Grayscale's Spot ETF Advance Intensifies Hype Around the 'Next Bitcoin'

Zcash surged 48% to surpass $800 for the first time since 2018, driven by talks of the "next Bitcoin," record futures volumes, and Grayscale's application for a spot ETF. The privacy-focused token, built on Bitcoin's design with a 21 million supply cap and proof-of-work mining, broke its January 2018 peak of around $800. It traded between $589 and $851 within 24 hours, a 45% swing. Grayscale, owned by Digital Currency Group (DCG), filed its fourth amendment to convert its Zcash Trust into a spot ETF (ticker ZCSH) on NYSE Arca, though SEC approval is pending. The filing also notes that another DCG subsidiary is in talks to acquire approximately 200,000 ZEC (worth about $163 million at the time) for the trust. Zcash futures volume hit approximately $4.55 billion on Friday versus about $553 million in spot trading, with open interest around $1.35 billion. This leveraged activity can amplify both rallies and corrections; Zcash experienced a sharp selloff in June after a vulnerability was found in its Orchard shielded pool. Zcash now ranks 12th by market capitalization at $13.87 billion, leading all other privacy-focused tokens.
