Boffins improve blockchain security

More resistant to quantum computing attacks


A team of boffins have emerged from smoke-filled labs with a cure for a problem which has not arisen yet. 

The issue is that as computers become all packed full of quantum chips with super-fast cats working in different levels of reality, blockchains security is going to be a doddle to knock over.

The boffins from the Inter-American Development Bank (IDB), Cambridge Quantum (CQ) and the Monterrey Institute of Technology have identified as well as resolved several potential threats to blockchain networks posed by quantum computers.

To combat these threats, the project team has developed a cryptographic layer that enables blockchain networks to protect themselves from attacks carried out using quantum computers.

The post-quantum cryptographic layer developed by IDB, CQ and the Monterrey Institute of Technology protects networks and offers resistance to quantum computer attacks was developed on the LACChain Besu blockchain network which is based on Ethereum technology.

During testing, transactions and communications were protected with quantum-proof keys from CQ's IronBridge platform that uses quantum computers to generate certified entropy.

CEO of IDB Lab Irene Arias Hofman provided further details on the project team's breakthrough in a press release, saying: “In the digital age in which we find ourselves we have at our disposal different emerging technologies with the capacity to solve social problems, and to the extent that we are able to combine them we will achieve an exponential impact. In this case, the knowledge of the IDB team, together with CQ and TEC, in both quantum and blockchain technologies, has made it possible to achieve a fundamental milestone to guarantee the future integrity of LACChain, a blockchain platform created by the IDB Lab which more than 50 entities in the region are using already.”
