Actual network rules will need to come later. However, even just not

Hello all,
as some may know, Bitcoin uses DER-encoded signatures in its transactions.
However, OpenSSL (which is used to verify them) accepts more than just the
strict DER specification (it allows negative numbers, extra zero padding,
extra bytes at the end, and
It'd help to know how the signatures are invalid.

The majority (~90%) is negative R or S values (which are just interpreted as
