IBM offers advice on how to secure blockchain in the cloud

Cloud providers hosting blockchain secure transactions technology should take additional steps to protect the records, IBM says.

IBM’s new framework for securely operating blockchain networks, released Friday, recommends that network operators make it easy to audit their operating environments and use optimized accelerators for hashing — the generation of numbers from strings of text — and the creation of digital signatures to pump up CPU performance. 

Along with the security guidelines, IBM announced new cloud-based blockchain services designed to meet existing regulatory and security requirements. The company has worked with security experts to create cloud services for “tamper-resistant” blockchain networks, it said.

The new cloud services are “an iron-clad way to achieve that level of security,” said Holli Haswell, an IBM spokeswoman. “Not all clouds can necessarily attain that level of security and compliance today.”
