BNB

BNB Chain said a proof-of-concept upgrade to post-quantum cryptography kept BSC operating but cut throughput by roughly 40% on May 19, 2026. Cross-region performance fell from about 4,973 transactions per second to around 2,997, mainly due to much larger transaction payloads and block sizes rather than signature verification delays.

BNB Chain completed a live post-quantum migration experiment on BSC, adding ML-DSA-44 signatures and pqSTARK aggregation while keeping wallets, SDKs, RPCs, and address compatibility intact. Under production-like conditions, native transfer throughput fell nearly 40% (4,973 TPS to 2,997 TPS), gas throughput dropped about 50%, and block sizes expanded almost 18x toward ~2 MB, highlighting scalability tradeoffs.

BNB Smart Chain developers completed a large-scale test of post-quantum cryptography on a live-style blockchain setup, swapping transaction signatures to NIST’s ML-DSA-44 and upgrading vote aggregation with pqSTARK proofs. The shift lifted average transaction size from about 110 bytes to roughly 2.5KB and expanded blocks from ~130KB to nearly 2MB at similar load, while throughput declined 40%-50%. The team said the results show quantum-safe migration is feasible with today’s standards, despite clear performance trade-offs.

Iran’s largest crypto exchange Nobitex processed at least $2.3 billion on Tron and BNB Chain since January 1, 2023. The activity continued after February when Trump’s war began, including at least $22.6 million on BNB Chain and at least $550,000 on Tron. World Liberty Financial said it has no relationship with Nobitex and does not own, operate, or control Tron.

Grayscale and VanEck filed amendments to their spot BNB ETF registration statements with the SEC on Friday, a step analysts view as evidence the agency is actively reviewing the proposals. Bloomberg ETF analyst James Seyffart said the updated filings suggest the SEC is providing feedback on disclosures and product mechanics. Both applications describe spot BNB funds that would launch without staking and list Coinbase as custodian.

BNB traded around $650 after slipping 1.25% over the past 24 hours, while volume fell 51.9% to nearly $772 million. The daily chart shows repeated rejection near $680, with $648 flagged as immediate support and a daily close below it potentially setting up an 11.5% drop toward $578. Derivatives positioning leaned bearish with a 0.8407 Long/Short Ratio, even as exchange data showed over $14 million in net outflows over the past 48 hours.

On May 16, Grayscale filed a second amended S-1 for its proposed spot BNB ETF, while Vaneck updated a competing application the same day. Bloomberg ETF analyst James Seyffart said the Grayscale amendment suggests the SEC is actively reviewing and providing feedback to issuers. The filings outline products that exclude staking and use Coinbase as custodian, with Nasdaq also needing an approved 19b-4 before trading can begin.

VanEck and Grayscale filed updated SEC amendments on Friday for their proposed U.S. spot BNB ETFs, with VanEck submitting Amendment No. 5 and Grayscale filing Amendment No. 2. The filings keep staking out of the initial launch while retaining conditional language, and both products are proposed to list on Nasdaq under tickers VBNB and GBNB. Separately, Canary Capital amended its staked TRX ETF S-1 on Friday and added service-provider details, while leaving the exchange, ticker, and management fee undisclosed.

BNB is trading near $655 with a market cap of $88.39 billion and a 0.9% rise over the past seven days. As of May 16, 2026, weekly charts show consolidation after a mid-May push toward $690, while Grayscale and VanEck have continued updating spot BNB ETF filings. The report also cites quarterly burns topping 1.5 million BNB in the latest cycle as part of the on-chain backdrop.

VanEck and Grayscale have updated their S-1 registration filings for a proposed U.S. spot BNB ETF, a move that Bloomberg ETF analyst James Seyffart said points to active SEC engagement. After the updates, some large holders reportedly rotated out of $50M in Ethereum into BNB, while BNB traded at $660 at press time.
