@ -23,7 +23,7 @@ This document proposes to restrict valid signatures to exactly what is mandated
Every signature passed to OP_CHECKSIG, OP_CHECKSIGVERIFY, OP_CHECKMULTISIG, or OP_CHECKMULTISIGVERIFY, to which ECDSA verification is applied, must be encoded using strict DER encoding (see further).
These operators all perform ECDSA verifications on pubkey/signature pairs, iterating from the top of the stack backwards. For each such verifcation, if the signature does not pass the <code>IsValidSignatureEncoding</code> check below, the entire script evaluates to false immediately. If the signature is valid DER, but does not pass ECDSA verification, opcode execution continues as it used to, causing opcode execution to stop and push false on the stack (but not immediately fail the script) in some cases, which potentially skips further signatures (and thus does not subject them to <code>IsValidSignatureEncoding</code>).
