We are CheckSig

CheckSig may seem an unusual name, but it is actually a word used at the heart of Bitcoin’s security model.

OP_CHECKSIG is a Bitcoin Script’s operation code, used to verify that a transaction signature is valid.

In other words, the CheckSig opcode is the guard of your Bitcoins. It works behind the scene to ensure that only the proper private key can move your funds.

So, it only made sense that we chose it as our company name! Security is our core mission.
