CALCTOPIA LIMITED

Calctopia Limited is a technology firm that builds scalable blockchain infrastructure on what it describes as the world's largest identity network. The company's platform supports private and verifiable smart contracts, offering a standard-compliant, secure environment for blockchain-based transactions. Users can explore the network through a dedicated blockchain explorer that works with Firefox and Chrome browsers.

A standout offering is SECCOMP - the Secure Spreadsheet - the first end-user programme that brings encrypted secure computation to Microsoft Excel. By leveraging patented cryptographic techniques, SECCOMP enables organisations in accounting, auditing, finance, statistics and actuarial fields to negotiate M&A, LBOs, debt refinancings and other investment deals while keeping sensitive data confidential. The tool requires only basic spreadsheet knowledge, giving a second life to existing workbooks without the need for specialised mathematical expertise. A limited free trial is available, with full functionality provided on a monthly subscription basis. Calctopia's solutions aim to let businesses profit from secret information without ever exposing it.
