Mark Walport Quotes
Distributed ledgers are inherently harder to attack because instead of a single database, there are multiple shared copies of the same database, so a cyber stack would have to attack all the copies simultaneously to be successful.

Many computer experts and security operatives view this kind of advice and strategy as counter-productive as there are some computer security extremists who so harden computer systems and networks that they function poorly and cause really harmful operational problems. The classic case was the FBI agent in Minnesota who before 9-11 had information that Muslims foreigners were taking flying lessons. She wanted to get the information to the national security FBI people, but she was not allowed to send the information by e-mail. Instead she had to use a "secure" system that was much slower and could not be viewed by the people who might have been able to connect the dots and do something about it. The FBI has now a better balance between functionality and security, but it is a good example of how "security fanaticism" can make us less safe.
Ironically, it was the case that there was even more hacking that was motivated by people who just wanted to prove that they could ‘breach a system’ and the more an organization claims that its data is secure, the more motivation there is for these hackers to demonstrate their prowess.
