Context:
- In early Bitcoin (2009–2010), signature validation relied on OpenSSL’s permissive parser. Non‑strict DER encodings that OpenSSL accepted could be considered valid then.
- Bitcoin Core made “strict DER” a consensus rule in 2015 (BIP66). BCH inherited that, and BSV split from BCH in 2018.
- BSV’s 2020 Genesis/Chronicle updates explicitly removed several post‑Satoshi consensus/policy constraints (e.g., CLEANSTACK) to increase permissiveness, but I couldn’t find an authoritative BSV protocol reference that clearly states whether strict DER (BIP66) was retained or removed at consensus level.
