Hormuz Strait Now Seeing Cryptocurrency “Safe Passage Fee” Scam Messages
According to Reuters, Greek maritime risk management company MARISKS has warned that some shipping companies stranded west of the Strait of Hormuz have received fraudulent messages impersonating Iranian authorities, demanding payment of a “transit permit fee” in Bitcoin or Tether (USDT). These messages are scams and not issued by official Iranian authorities. MARISKS stated that the scam messages claim documents must first be submitted and assessed by the “Iranian Security Department” before the cryptocurrency fee is determined. Currently, approximately hundreds of vessels and around 20,000 seafarers are stranded in the Gulf. During Iran’s brief opening of the Strait on April 18, at least two vessels—including one oil tanker—were forced to turn back after Iranian vessels opened fire on them.
StarkWare Researcher Proposes Bitcoin Post-Quantum Transaction Scheme Without Soft Fork
According to The Block, Avihu Levy, a researcher at StarkWare, published a paper proposing the Quantum Safe Bitcoin (QSB) scheme, claiming it enables quantum-resistant transactions under Bitcoin’s existing script rules—without requiring a soft fork. This scheme replaces elliptic-curve cryptography with the RIPEMD-160 hash function via a “hash-to-signature” puzzle, thereby enhancing resilience against quantum attacks. The paper notes that QSB’s current per-transaction cost ranges from $75 to $150—significantly higher than today’s average transaction fee—and involves complex user experience; thus, it is recommended only as a “last resort.” The scheme remains constrained by script opcodes and size limits, and does not yet support all use cases—such as the Lightning Network. Compared to BIP-360—which requires protocol-level changes—QSB needs no modifications to the Bitcoin protocol, but remains experimental.
