The debate reflects tension between defensive design choices and future flexibility in Bitcoin’s slow upgrade cycle. His comments focused on SPHINCS+, a hash-based signature scheme that some developers view as a safe option against…

Stratiphy Restores Crypto ETN Access for UK Investors via New ISA Offering

UK fintech platform Stratiphy has launched a new offering that gives investors a practical tax-free route back into crypto exchange-traded notes (ETNs) for UK investors after a series of regulatory shifts effectively shut investors out.

These products could initially be held in standard stocks-and-shares Individual Savings Accounts (ISAs), offering tax-free exposure. However, that changed at the start of the new tax year, when HM…

Critics said the Security Council’s intervention raised fresh concerns about centralization and emergency governance powers. He said the move was comparable to Bitcoin’s response to the 2010 value overflow bug, when the network accepted a rollback after an…
