The largest British Telecommunications Provider is commissioned to develop security measures on the use of Blockchain Technology. We all know that the rising fame of Blockchain has ignited the interest of both the public and different industry sectors.
It has bought the modernization of processes across these sectors in our society. One of the concerns though is the imminent security concerns. There are certain groups of individuals who are trying to circumvent the process behind this technology. The malicious intent to create ways on how to breech the security of Blockchain is a pressing issue that we need to be in the lookout for.
British Telecom Awarded Patent for Blockchain Security Method
The U.K.’s largest internet and telecoms provider has been awarded a patent for a proposed cybersecurity measure aimed at protecting blockchains.
In the patent, awarded on Oct. 31, British Telecommunications PLC (BT) outlined a method designed to prevent malicious attacks on blockchains – outlining a way to limit who can commit transactions to the system through user-specific profiles. The blockchain’s underlying code would then be able to automatically reject transactions which do not match the pre-described accounts.
One example use case outlined by the patent includes “majority control attacks” (also called “51 percent attacks”), where a hostile force with more than 50 percent of the total computing power tries to control a blockchain network.
According to the patent:
When an attack is detected, the system will automatically stop conducting transactions, preventing even a majority attack from being effective, according to the patent.
The patent further cites include distributed denial-of-service (DDoS) attacks, which are designed to completely overwhelm a miner with an excessive number of transaction requests.
BT does not address how it would deal with such attacks, however, it does state that “it would be advantageous to provide a mechanism for detecting and mitigating threats to blockchain environments.”
While the patent discusses the method of verifying transactions through the energy-intensive mining process employed by digital currencies like bitcoin, BT notes that the process is unrelated to the patented system.
