[thebalaa]

From https://bitcoinsv.io/contact/

• Restoring more original Satoshi op codes: OP_MUL, OP_LSHIFT, OP_RSHIFT, OP_INVERT
• Removing the limit of 201 op codes per script
• Raising the maximum block size to 128 MB

Thank you for your interest in bcash. Unfortunately, currently we don't have any plans on supporting those changes. But It should be possible and welcome to fork bcash apply those changes.We will be releasing a new, stable version of bcash in the coming days, so probably that is good place to fork from.

Hey @thebalaa - I forked bcash for SV

@nodar-chkuaselidze If you guys do decide to support SV, you can take the port. A few TODOs remain that I probably won't get to:

• Move the new opcode tests to magnetic-tests
• Add additional tests for the new opcodes
• Apply block size and script len as part of magnetic activation
