Blockchain technology is transforming the way data is shared and value is transferred. However, there remain significant obstacles that must be overcome before blockchain is ready for mainstream adoption – most notably, security. How to protect both the cryptographic keys that allow access to the ledger and blockchain applications remains a top concern for any organisation or individual interested in using blockchain to transact anything of significant value.

Blockchain technology is transforming the way data is shared and value is transferred. However, security concerns must be overcome before it is ready for mainstream adoption.

Protecting cryptographic keys remains a top concern. Using hardware security modules (HSMs) and trusted computers in place of digital wallets and as blockchain nodes will give security-conscious users and organisations assurance that no matter what blockchain application they choose, they have the means to protect digital assets, argues Olivier Boireau of Design SHIFT.
