Blockchain processes transactions with secure communication, privacy, resilience, non-repudiation, and transparency. These are necessary attributes in a low-trust scenario. The technology is a popular choice in systems where the data needs to be securely transferred between different parties–without letting adversaries lay their hands on it.

Blockchain will prevail due to fast-changing business needs across verticals like banking, logistics, and telecom. However, with the advent of quantum computers, predicting the future of blockchain safety may be tricky.

Conventional security in blockchain may pose problems in the future. The only way forward is to adopt quantum-safe security on top of the present security infrastructure. It will enable users to adopt blockchain and its value without any security concerns.
