The Bitcoin protocol itself cannot be modified without the cooperation of nearly all its users, who choose what software they use. Attempting to assign special rights to a local authority in the rules of the global Bitcoin network is not a practical possibility. Any rich organization could choose to invest in mining hardware to control half of the computing power of the network and become able to block or reverse recent transactions.
What is TSA Preâ? To trim ever-winding airport lines, the Transportation Security Administration has rolled out a program that eliminates a few cursory security checks for approved frequent fliers. And in typical government fashion, it has a fancy name: TSA Preâ. No, this is not TSA Precheck, but TSA Preâ, a service that likely won't play nice with Google search, but will certainly piss you off the more times you read it in print.
In conjunction with the Transportation Security Administration (TSA), certain members of CBP's Trusted Traveler programs, are eligible to participate and may receive TSA PreCheck expedited screening benefits at select U.S. airport checkpoints. All Global Entry members are eligible for TSA PreCheck. U.S. citizens and U.S. lawful permanent residents enrolled in NEXUS and SENTRI are also eligible for TSA PreCheck. Canadian citizens who are members of NEXUS are also eligible to participate in TSA PreCheck.
