SCRIPT_VERIFY_MINIMALDATA property
Require minimal encodings for all push operations (OP_0... OP_16, OP_1NEGATE where possible, direct pushes up to 75 bytes, OP_PUSHDATA up to 255 bytes, OP_PUSHDATA2 for anything larger). Evaluating any other push causes the script to fail (BIP62 rule 3). In addition, whenever a stack element is interpreted as a number, it must be of minimal length (BIP62 rule 4). (softfork safe)
Implementation
static final SCRIPT_VERIFY_MINIMALDATA = (1 << 6);
