Flowra Launches Open Orderflow Auction for Solana Block Building

TheNewsCryptoPublicado a 2026-08-21Actualizado a 2026-08-21

Resumen

Solana's block building and MEV landscape is seeing a significant shift with Flowra's launch of the Open Orderflow Auction (OOA). This new system aims to decentralize transaction ordering, which is currently concentrated, by replacing reliance on private channels with an open auction where registered searchers compete. The goal is to improve competition and price discovery, allowing validators to capture more value from MEV. Early tests showed positive outcomes, including a 20.6% increase in compute units per block for one validator and reports of higher fees and robust uptime. Flowra also introduced a Programmable Block Policy, giving validators greater control over transaction inclusion for compliance needs, and partnered with Honeypot for sanctions screening. Inspired by Ethereum's successful model, Flowra believes Solana's high throughput is well-suited for open block-building auctions. The system is now available, with an institutional onboarding phase underway ahead of a broader rollout.

Solana’s ecosystem is undergoing a major infrastructure shakeup. Flowra, a blockchain infrastructure company has launched a new block-building system for Solana called the Open Orderflow Auction (OOA), which is designed to create more competition around transaction ordering and give validators a larger share of the value generated by MEV.

Right now, a huge portion of Solana’s transaction ordering and MEV (Maximal Extractable Value) market remains tightly concentrated. Traditionally, many validators rely on closed orderflow channels.

Flowra’s new open auction system changes that by allowing registered searchers to compete for transaction inclusion through an open auction instead of relying on private orderflow channels. Flowra says this approach could improve price discovery while giving validators more opportunities to earn from the demand for Solana blockspace.

Early testing showed promising results. On one validator, a Flowra-enabled setup increased compute units per block by 20.6%, taking the validator from 84% to 101% of the network average. The company also reported higher block fees than comparable validator software, along with full block production and 99.999% block engine uptime during the test.

Flowra Adds Validator Controls and Compliance Screening

Alongside the auction, Flowra has introduced Programmable Block Policy, giving validators more control over which transactions are included in their blocks. This could be useful for validators that need to follow specific regulatory or institutional requirements without making changes to the Solana protocol itself.

Flowra has also announced a collaboration with compliance infrastructure provider Honeypot to bring sanctions and risk screening to this block-building layer.

The company said its approach draws from Ethereum’s competitive block-building market, where open bidding has helped increase proposer revenue. Flowra believes Solana’s high transaction throughput and low latency could support a similar model.

Flowra is currently onboarding institutional-grade validators to the Open Orderflow Auction, with a wider rollout expected as participation grows. The system is now available to validators and searchers operating within the Solana ecosystem.

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.

Cryptocurrency Transfers Abroad: What Changes for Russians Starting September 1st

From September 1, 2026, a new Russian law will legalize cryptocurrency transfers abroad for citizens. The regulations will allow sending crypto to personal foreign wallets and using it for payments to foreign businesses, provided established rules are followed. The law recognizes crypto as property and introduces a legal framework for its circulation, permitting both qualified and non-qualified investors (with an annual limit of 300,000 rubles for the latter) to buy cryptocurrencies and stablecoins. Notably, using crypto for domestic payments within Russia remains illegal and subject to fines. Companies can use crypto for foreign trade contracts, but these transactions remain under currency control and anti-money laundering (AML) scrutiny. Major banks are increasing oversight of crypto operations, requiring detailed explanations for business transactions, with stricter controls expected from July 2027. While providing new legal avenues, the article warns of risks. Users must choose transfer methods (exchanges, P2P platforms, crypto exchangers) carefully, considering fees, speed, and service reliability. Key risks include service providers freezing transactions, demanding documentation, or blocking accounts. Experts caution that even popular assets like Bitcoin can be tracked or potentially targeted, and sanctions may restrict access to international platforms. Ultimately, while legalized, cross-border crypto transfers will operate within a framework of enhanced state control over fund origins and counterparties.

Bryansk Residents Explained How to Recognize Cryptocurrency Mining from Neighbors

Residents of the Bryansk region are advised on how to detect cryptocurrency mining operations by their neighbors. Key signs include a constant, monotonous hum from cooling fans, noticeable heat emission and a smell of overheated electronics, as well as electrical issues like circuit breaker trips, voltage fluctuations, and flickering lights, especially in older buildings with weaker wiring. Mining involves computers solving complex computational problems to verify blockchain transactions, consuming significant electricity and generating heat. Equipment ranges from specialized ASICs to graphics card setups, requiring robust power supplies and cooling systems. Miners often join pools to combine computing power. While cryptocurrency operations are legal in Russia, risks include high power loads, equipment overheating, noise complaints, and financial losses due to price volatility. From September, digital currencies will be legally recognized as property, and residents will be allowed to transfer crypto abroad under specific regulations.

GensynAI's Jeff Amico States That Real-World Asset (RWA) Investors May Lose Creditor Rights

Jeff Amico of GensynAI warns that investors in Real-World Asset (RWA) tokenized lending pools may lack creditor rights in case of borrower default. He notes a common structure where users receive a yield-bearing stablecoin from a platform, but the underlying loan and collateral are held by separate legal entities. This setup means investors have no enforceable claims against the borrower, the special purpose vehicles (SPVs), or the collateral itself, relying instead on the platform's promise to return funds. Amico emphasizes that investors must first identify who legally owes them money and what credit enhancement mechanisms exist, rather than focusing solely on nominal yield. Protections like collateral or first-loss capital are meaningless unless the lien is properly perfected and an agent is designated to enforce it on the investor's behalf. Investors without a formal credit agreement are particularly vulnerable. He cites Pareto/FalconX as a better model where depositors are direct contractual creditors, though this comes with higher minimum investments and KYC requirements. This highlights a trade-off: the crypto industry's permissionless ideals often conflict with the legal protections required for secure lending. Amico argues that weak legal structures could limit the RWA sector's growth. Traditional finance offers a clear template with defined creditor rights and perfected liens. Tokenized lending needs infrastructure, like oracles, to verify off-chain loan agreement status and collateral perfection, as smart contracts cannot do this autonomously. Ultimately, transparency is key. Some investors may accept weaker protections for open access, while others may prefer stronger legal rights. The legal structure of a lending pool will be as critical as its advertised yield, especially during a default, determining whether a token holder has enforceable rights or merely a platform promise.
