Chris Howell, CTO and co-founder of Wickr, a videoconferencing and collaboration platform that features end-to-end encryption, shared that concern and said managing the data entry and cryptography on a mobile client or e-voting machine can be extremely challenging.
“Blockchain can be very precise, but it requires precision from square one,” Howell said. “If it’s not done correctly at the local level, then the data going into the ledger may not be accurate and then your immutable data is just immutable rubbish.”
