# ATAC Global CX > ATAC Global CX is a blockchain-verified credentialing platform for the global remote customer experience (CX) workforce. We certify work-from-home customer service agents through the CRSA (Certified Remote Service Agent) credential, assessed with a knowledge exam and a live voice simulation that measures real call-handling skill. Every credential is verifiable on-chain, giving agents portable proof they are call-ready and giving employers and BPOs a fast, fraud-proof way to confirm a candidate before going live.
