The company
CheckSig origins
It all began with the Digital Gold Institute (DGI), our consulting, training, research and development center on Bitcoin, crypto assets, and blockchain technology.
At DGI, professionals with varied expertise – finance, academia, banking, strategic consulting – came together and found investors needed a reliable Bitcoin and crypto partner.
CheckSig name
“OP_CHECKSIG” is a Bitcoin Script language instruction, for verifying that signatures authorizing a transaction are valid.
CheckSig defines what we do and why we are here: to safeguard your Bitcoins.
