BSC Post-Quantum Upgrade Clears Major Test as Network Throughput Drops 40%

The move to quantum-resistance of blockchain infrastructure is bringing new challenges to the forefront besides cryptography design, namely, heavy data overhead caused by post-quantum algorithms. BNB Chain Developers made the announcement recently on the BSC Post-Quantum Cryptography Migration Report which describes successful implementation of post-quantum upgrades to the network. All of these upgrades used ML-DSA-44 for transaction signatures and pqSTARK for consensus vote aggregation. Importantly, the report verifies that the novel cryptographic mechanisms are backwards compatible with existing addresses, wallets, RPC interfaces and SDKs allowing the network to maintain its current architecture while priming itself for upcoming quantum threats. Nevertheless, testing revealed a key scalability issue. By introducing these quantum resistant signatures we saw a downward shift in terms of network performance, this was attributed mainly to the increase in data being passed around the network. A lot of people assume the hardest part of post-quantum cryptography is the cryptography itself. In our testing, that wasn’t really the case. The bigger challenge came from the amount of additional data moving through the network once quantum-resistant signatures were… pic.twitter.com/r5xAc0KKfb — BNB Chain Developers (@BNBChainDevs) May 19, 2026 Signature Sizes Bring New Scaling Pressure As per BNB Chain analysis of the incident, the main challenge was not verifying signature and cryptographic calculations but dealing with large growing transaction data size. The size of a normal transaction signature grew from 65 bytes to ~2.4 KB when integrated ML-DSA-44 It fully propagated through the network stack: transaction sizes rose from approximately 110 bytes to nearly 2.5 KB, and block sizes swelled from around 110 KB to nearly 2 MB. These increased-size payloads limited propagation overhead between regions, consequently significantly reducing the maximum throughput of the network. The cross-region testing quickly revealed the performance hit, where native transfer throughput fell from 4,973 TPS to around 2,997 TPS, almost a minus-40% drop. Developers emphasized that the cryptographic computations themselves were still relatively manageable during tests. The throughput drop came mainly from the additional cost of data transfer and inter-block synchronisation between validators across multiple regions. Contrary to popular belief, the biggest hurdle in post-quantum blockchain upgrades is not algorithm design. However, according to BNB Chain, bandwidth efficiency and data-layer scalability might be the more significant long-term constraints. Compatibility Remains A Major Advantage Despite the throughput decline, BNB Chain stressed that its post-quantum framework was engineered to be compatible with the chain’s current ecosystem. The testing phase showed that wallet integrations, RPC functionality, SDK support and address formats worked as before without many disruptions. Backward compatibility decreases migration friction and could enable adoption ease if post-quantum security begins becoming a sector-wide requirement. Second, most wallets in the space are designed for use with other chains, whether it’s ethereum or bsc. The report further reveals that BNB Chain is taking an incremental route toward post-quantum readiness rather than imposing a rapid transition. This is just a promise, and developers recognize that there remain unresolved points regarding network and data-layer scaling before production-level deployment can be considered practical. Quantum Concerns Continue Growing Across Crypto When the quantum computing area is progressing greatly recently, post-quantum cryptography has raised meaningful attention in the blockchain community. Current blockchains are built on cryptographic schemes which could be broken by a sufficiently powerful quantum adversary. While experts disagree about how imminent this threat is, several major ecosystems are already exploring migration trends to quantum-resilient protocols. It furthermore serves as a harbinger of things to come in blockchain scaling. In addition to optimizing execution speed and gas costs, data efficiency, propagation strategies, and validator communication architectures may move into focus as quantum-resistant signatures reach production environments. However, BNB Chain developers stress that the technology needs more fine-tuning before mass-usage is feasible. Binance Launches HTTP-native x402 Payments Binance announced Binance x402 underlined as a programmable payments framework based on HTTP and built on BNB Chain. Targeting agent-driven commerce and software-native financial interactions, this system empowers applications and autonomous agents to perform programmable payments directly over vanilla HTTP 402 payment flows. The framework includes off-chain authorization and on-chain settlement, as well as pay-per-call and usage-based billing models, according to Binance. This architecture has been created to help machine-to-machine transactions and automated software payments without an overreliance on conventional payment rails. Binance also notes its support for autonomous transactions, part of a growing strategy to create crypto financial infrastructure designed usable by AIs across the BNB Chain. The purpose of the launch coincides with growing curiosity among blockchain networks around payment solutions for AI agents, automated APIs and decentralized software services.

Beyond consumer-facing applications, the ecosystem is rapidly prioritizing long-to-to-long network resiliency and how & when architecture can be future-proof. The post-quantum report reveals technical challenges that continue to impede large-scale quantum-resistant deployment, including the ability of validators to synchronize with data throughput in high-pressure conditions. On the other hand, Binance x402 projects BNB Chain into an era where software programs and AI-driven applications will autonomously be performing work as parts of blockchain economies. These announcements collectively shape a larger trend in evolution away from pure transaction execution on the blockchain at scale. Where it gets most critical is less about if post-quantum cryptography actually fits inside the BNB Chain ecosystem, and more in how that data should be stored as a by-product of those systems.

Dogecoin Price Prediction: Bulls Fight for 10 Cents as $1 Target Reappears

Dogecoin is testing the key 10-cent level after a rejection from weekly Fibonacci resistance. At the same time, another long-term chart shows a rounded recovery setup, with $0.278 as the first major breakout target before any move toward $1 Dogecoin Price Tests 10-Cent Support After 0.618 Fib Rejection Dogecoin price is pulling back after hitting the 0.618 Fibonacci level near $0.11825 on the weekly chart shared by Surf on X. The DOGE chart shows price moved higher from the lower support zone near $0.08063, which marks the 0.786 Fib level. After that bounce, Dogecoin climbed toward the 0.618 Fib resistance but failed to hold above it. DOGE/USD Weekly Price Chart. Source: Surf on X DOGE is now trading near $0.10429, close to the key $0.10 level. Surf marked this area as the main level to watch after the recent correction. The chart shows the $0.10 zone has acted as a major mid-range level before. If Dogecoin holds above it, the current move can still look like a healthy pullback after the Fib rejection. However, a weekly close below $0.10 would weaken the setup. It would bring the lower Fib support near $0.08063 back into focus. The descending trendline from the previous highs has already been broken. That gives bulls some structure, but DOGE still needs to reclaim the $0.11825 level to show stronger upside. For now, Dogecoin remains between two important areas. The $0.10 level is short-term support, while $0.11825 is the next resistance level DOGE needs to clear. Dogecoin Chart Shows $0.278 Breakout Target Before $1 Call Dogecoin is forming a rounded recovery setup on the weekly Coinbase chart shared by Celal Kucuker on X, with the first major upside target marked near $0.27855. The DOGE/USDC chart shows price holding above the lower support zone near $0.08779. This area acts as the base of the current structure after Dogecoin’s long decline from its previous highs. DOGE/USDC Weekly Price Chart. Source: Celal Kucuker on X The chart also shows a curved accumulation pattern under a major resistance zone near $0.27855. That level has blocked price before, so DOGE needs a weekly breakout above it to confirm stronger upside. Celal Kucuker also marked a larger move toward $1.0001. However, that target depends on DOGE first clearing the $0.27855 resistance area and holding above it. The chart suggests a staged move. First, DOGE needs to keep support above the lower range. Then it needs to break the mid-range resistance near $0.27855. Only after that would the $1 target become more relevant. For now, the setup shows recovery structure, not confirmation. Dogecoin remains below the main breakout level, so the $0.27855 zone is the first key level before any larger move toward $1.

What Is the Cheapest Way to Send USDT in 2026?

Solana SPL USDT carries the lowest per-transfer fee in 2026 at roughly $0.001, well under a cent. TRC-20 USDT runs close behind, often free for senders with staked TRX for energy, and remains the network most stablecoin users actually transact on. Cheapest in absolute terms is not always cheapest in practice. A sub-cent transfer to a wallet that doesn't support the chosen network loses every cent of its value. Wallets like IronWallet that handle both TRC-20 and Solana stablecoin transfers, with gasless mechanics on the Tron side, let users pick whichever network the recipient actually uses without paying separately for network gas. The Cheapest USDT Networks in 2026 Per-transfer USDT transfer fee 2026 numbers across the major networks supporting USDT vary by four orders of magnitude. The lowest USDT fee sits on Solana, with several other options close behind. Figures below reflect typical conditions in early 2026, not worst-case spikes. Solana SPL USDT transfers cost roughly $0.001 per send, with confirmation in about one second. TON USDT sits at around $0.005, with the Telegram-integrated wallet enabling fee-free transfers between Telegram contacts. Polygon USDT costs around $0.001 to $0.005, depending on network conditions. Arbitrum, Optimism, and Base all sit between $0.05 and $0.15 for standard transfers. TRC-20 USDT ranges from effectively zero (with staked TRX for energy and bandwidth) to about $1.40 (burning TRX if no energy is available). Most active senders pay closer to $0.20 by renting energy through specialized services. BEP-20 USDT on BNB Chain runs around $0.10 to $0.30 per transfer with three-second confirmation. Ethereum mainnet ERC-20 USDT remains the most expensive at $2 to $15 typical, occasionally exceeding $30 during peak congestion. Why TRC-20 Remains the Practical Default Despite Solana carrying the lowest raw fee, TRC-20 sits at the center of stablecoin transfers in 2026 for reasons that extend past per-transaction cost. Universal support is the first factor. Almost every major centralized exchange, including Binance, Coinbase, Kraken, OKX, Bitget, and Bybit, supports TRC-20 USDT for deposits and withdrawals. Most non-custodial wallets handle it natively. The recipient on the other end almost certainly has a way to receive it. Supply weight tells the same story. Roughly half of the entire USDT circulating supply now lives on Tron , per Tether's transparency reports as of April 2026. Ethereum holds about 40%, and the remaining 10% spreads across Solana, Avalanche, L2 networks, and others. Mature off-ramp infrastructure follows from that supply weight. Regional exchanges in Latin America, Africa, and Southeast Asia treat TRC-20 as the default rail. P2P platforms route around TRC-20 liquidity. Remittance corridors run on TRC-20 at scale because the network has the depth. Energy management closes the loop. Senders who stake TRX earn enough energy and bandwidth daily for free transfers, and rental services let occasional senders rent energy for cents. The combination makes TRC-20 effectively free in practice for active users. When Solana SPL USDT Makes Sense Solana SPL USDT earns its cheapest-on-paper status by genuine technical merit. Sub-cent fees, one-second finality, and a growing share of stablecoin volume make it the right network for specific scenarios. High-frequency wallet-to-wallet transfers benefit most. A user sending USDT dozens of times per day to Solana addresses pays a few cents in total fees across the month. The same pattern on Tron without staked energy costs dollars; on Ethereum, hundreds. Solana-native DeFi and payment apps fit naturally , too. Jupiter, Kamino, Drift, and other Solana protocols use SPL USDT directly, with no bridging required. Payments to merchants accepting Solana settle in seconds at the lowest available cost. One constraint remains: recipient compatibility. Solana exchange support has expanded substantially, but not every CEX deposit page lists it yet, and not every regional off-ramp handles it. How Gasless TRC-20 Closes the Cost Gap Gasless stablecoin transfers on TRC-20 let users send USDT on Tron without holding TRX for fees. The network fee comes out of the USDT itself, abstracted by the wallet. Users who want to send USDT cheap without managing a separate gas token find this the closest match to Solana's sub-cent experience. IronWallet implements this directly. A user with USDT in IronWallet sends to a TRC-20 address and pays the network cost from the USDT balance, with the wallet handling the energy and bandwidth backend. Net result: gasless TRC-20 matches Solana's user experience for stablecoin senders who prefer Tron's deep exchange and off-ramp support. No separate native token to acquire, no minimum balance for fees, no friction for users who only hold stablecoins. Energy rental services achieve a similar outcome through Telegram bots like TronCastle and dedicated platforms like TR.ENERGY, which let any wallet user rent energy for a small TRX payment instead of burning TRX directly. Choosing the Right Network for Your Recipient Any honest USDT network comparison ends at the same place: the cheapest USDT transfer is the one that lands in the recipient's wallet. Network choice is a recipient decision, not a sender preference. Practical rules for the most common cases: Sending to a centralized exchange: Check the exchange's accepted networks first. TRC-20 is the safest default; Solana works on most major venues now; ERC-20 only if cost truly doesn't matter Sending to a Solana wallet: Use Solana SPL USDT for the lowest cost and fastest settlement Sending to an Ethereum or DeFi user: Polygon or an L2 like Arbitrum or Base keeps the fee under $0.20 while maintaining EVM compatibility Sending to a friend's mobile wallet: Confirm which networks their wallet supports. Most multi-chain mobile wallets handle TRC-20 and Solana both; IronWallet handles TRC-20, ERC-20, Solana, Polygon, Base, and BNB Chain Sending across borders for remittances: TRC-20 offers the best balance of cost, recipient access, and local off-ramp availability in most corridors Conclusion Solana SPL USDT is the cheapest USDT transfer in 2026 at fractions of a cent. TRC-20 USDT with energy management runs nearly as low and works everywhere stablecoin users actually need to send. Practical answer: pick the network the recipient supports, then pick the cheapest among those options. Wallets like IronWallet that handle both TRC-20 and Solana with gasless TRC-20 mechanics give users that flexibility without the cost of holding multiple native gas tokens. A cheap send that arrives beats a free send that doesn't. Disclaimer: This article is provided for informational purposes only.

Russian Rouble Strengthens to Highest Level Against Yuan Since Early 2023

BitcoinWorld Russian Rouble Strengthens to Highest Level Against Yuan Since Early 2023 The Russian rouble has climbed to its strongest level against the Chinese yuan since early 2023, reflecting shifting dynamics in the currency market amid evolving geopolitical and trade conditions. The move underscores a broader realignment in Russia’s foreign exchange landscape as bilateral trade between Moscow and Beijing deepens. Rouble-Yuan Exchange Rate Reaches New Milestone Data from Moscow Exchange shows the rouble trading at its highest point against the yuan in over a year, a development that analysts attribute to a combination of factors including changes in trade flows, capital controls, and relative demand for the two currencies. The yuan has weakened broadly against the dollar in recent months, while the rouble has found support from Russia’s current account surplus and reduced import demand. The rouble-yuan pair has become increasingly significant as Russia pivots its trade away from Western currencies following sanctions. China has emerged as Russia’s largest trading partner, with bilateral trade volumes reaching record levels in 2023 and continuing to grow in 2024. This has boosted demand for yuan on the Russian market, while also creating new dynamics for the rouble. Why the Rouble Is Gaining Against the Yuan Several factors explain the rouble’s recent strength against the Chinese currency: Trade imbalances: Russia’s exports to China, particularly energy and commodities, have remained robust, while its imports from China have moderated. This has created a surplus of yuan in Russia, supporting the rouble. Capital controls: Russia has maintained strict capital controls that limit outflows, keeping rouble demand relatively high within the domestic market. Yuan weakness: The Chinese yuan has faced pressure from a slowing domestic economy and capital outflows, making it cheaper relative to the rouble. Policy divergence: The Russian central bank has kept interest rates high to combat inflation, attracting foreign capital and supporting the rouble. In contrast, the People’s Bank of China has eased policy to stimulate growth, weighing on the yuan. Implications for Trade and Markets The strengthening rouble against the yuan has mixed implications. For Russian exporters, a stronger rouble makes their goods more expensive in yuan terms, potentially reducing competitiveness in the Chinese market. For Russian importers, it lowers the cost of Chinese goods, which could help ease domestic inflation pressures. For Chinese firms trading with Russia, the exchange rate shift affects profit margins and may prompt adjustments in pricing strategies. The move also highlights the growing interdependence between the two economies, even as both face headwinds from Western sanctions and global economic uncertainty. Broader Context: De-Dollarization and Currency Shifts The rouble-yuan movement is part of a larger trend of de-dollarization in global trade, particularly among BRICS nations. Russia and China have increasingly settled trade in their own currencies, reducing reliance on the US dollar. This shift has made the rouble-yuan exchange rate a key barometer of bilateral economic relations. However, the rouble’s strength against the yuan does not necessarily reflect overall rouble stability. The Russian currency remains volatile against the dollar and euro, and its long-term trajectory depends on oil prices, sanctions developments, and domestic economic policy. Conclusion The rouble’s rise to its strongest level against the yuan since early 2023 marks a notable development in currency markets, driven by trade flows, capital controls, and diverging monetary policies. While the move benefits Russian importers and supports the rouble’s short-term stability, it also underscores the complex and evolving nature of Russia-China economic ties. Investors and businesses engaged in bilateral trade should monitor these exchange rate dynamics closely as they continue to shape trade competitiveness and financial planning. FAQs Q1: What is the current rouble-yuan exchange rate? The rouble has reached its strongest level against the yuan since early 2023, trading at approximately [specific rate if available, otherwise note: check current market data]. The exact rate fluctuates daily based on market conditions. Q2: Why is the rouble strengthening against the yuan? The rouble’s strength is driven by Russia’s trade surplus with China, strict capital controls, high domestic interest rates, and relative weakness in the Chinese yuan due to China’s economic slowdown and monetary easing. Q3: How does this affect trade between Russia and China? A stronger rouble makes Russian exports more expensive for Chinese buyers, potentially reducing competitiveness. Conversely, it lowers the cost of Chinese imports for Russia, which could help ease inflation. Businesses on both sides may need to adjust pricing and hedging strategies.
