DOT rallies 12% in a day as Polkadot gears up to solve a major blockchain hacking problem By Cointelegraph

(DOT) price ticked higher in the past 24 hours on anticipations that its new cross-chain communications protocol would solve a long-standing problem in the blockchain sector.

Bulls pushed DOT’s price to $16.44 on May 5 from $14.72 a day before, gaining a little over 12% as they assessed the launch of XCM, a messaging system that allows parachains — individual blockchains that operate in parallel inside the Polkadot ecosystem — to communicate with each other.
