New research from Florida Atlantic University and the University of Mississippi suggests that blockchains with "full" blocks and transaction queues provide an extra layer of protection against fraudsters and money launderers. The study, titled "Bitcoin Blocksize, Custodial Security, and Price," examines the Mt.Gox crash and other instances of cryptocurrency theft from exchanges. The researchers found that cybercriminals prefer to launder stolen bitcoin quickly, and that full blocks act as a deterrent to hackers and scammers by signaling network congestion and a rise in network security that affects bitcoin price. The study also found that block fullness is 20% lower on average during incidents of cryptocurrency breaches or fraud.
