Iota - Next Generation Cryptocurrency

iota is an open-source distributed ledger protocol that goes 'beyond blockchain' through its core invention of the blockless ‘tangle’. the iota tangle is a quantum-proof directed acyclic graph, with no fees on transactions & no fixed limit on how many transactions can be confirmed per second in the network. instead, throughput grows in conjunction with activity in the network; the more activity, the faster the network. unlike blockchain architecture, iota has no separation between users and validators; rather, validation is an intrinsic property of using the ledger, thus avoiding centralization. iota is initially focused on serving as the backbone of the emerging internet-of-things (iot).
