He explains how it is not possible to have both Security, Decentralization and Scalability at the same time. Close Modal Based on testing conducted in August 2015 with IBM. I've described above what Vitalik did in the past, calling it "The Scalability Trilemma". VisaNet can authorize up to 65,000 transaction messages per second, settling them to the penny, ruble, rupee, yen, centavo or santang. The networks that Visa and Mastercard use process, in aggregate, more than 5,000 transactions per second with capacity to process volumes multiple times that number. Because a transaction is 420 Bytes on average, we can calculate that Bitcoin can handle 1000000/420/ (1060)4 transactions. I don't know if Ripple can ever manage to become decentalized and since they don't actually care about this issue I totally doubt it. This coin has a block time of 10 minutes and a block size of 1Mbyte.
Others are not decentralized at all, meaning it is still like using a bank with different tech. Most of the alt chains have already been 51% attacked in the past. Are their networks as safe and secure as Bitcoin is though? Not at all. I've also heard about XRP and other chains claiming millions of transactions per second. Although with Lightning Network, which will be a layer-2 solution, transactions with Bitcoin will be almost instant and feeless. Anyone know a crypto that can handle more ? I know XRP can do 1700 transactions per second. If crypto wants to get fully adopted in future they will need the possibility to execute a very high number of transactions to meet the correct requirements for their crypto to process efficiently. If you divide that figure by 365, the results show that more than 108.6 million credit card transactions occur in the U.S.
#Visa transactions per second plus
plus another 5.66 billion from American Express and 2.72 billion from Discover. If you think about Visa for example, is able to transact 15000-20000 transactions per second. This figure includes 31.2 billion purchase transactions from the top 50 issuers of Visa and Mastercard credit cards in the U.S.
