nsaction speed declines as the network increases in size as more transactions compete for the limited block spaces. • It will take more and more computing power to mine the same amount of bitcoin. Vulnerable to Quantum attack • Bitcoin and other proof of work based blockchains are susceptible to being broken by a powerful quantum computer. There is another technology which has evolved called “IOTA”. IOTA ARCHITECTURE IOTA USES BLOCKDAG • IOTA is not an acronym for Internet of Things, IOTA just mean something very small. Block chains are sequential chains where blocks are added in regular intervals. • The tangle a DAG (Directed Acyclic Graph) is able to achieve high transaction throughput and no transaction fees on transactions. • As it grows and more participants make transactions, the overall system becomes more secure and faster, with confirmation times/ transaction finality going down. • But look it’s still uses distributed database, it’s still a P2P network and it still relies on a consensus and validation mechanism. • The more the nodes, the faster the transaction speed will be.
