Throughput
Throughput is a measure of how many units of information a system can process in a given time window. To measure performance on a transaction platform, throughput is expressed in terms of TPS, transactions per second:
- For Bitcoin, TPS can be computed as follows. A Bitcoin block normally contains 1,500-2,000 transactions. Let's use the high-end number, 2,000. Since it takes 60 minutes to confirm these 2000 transactions, its TPS = 2,000 / (60*60) = 0.56; that is, only half a transaction per second. A similar calculation for Ethereum yields a TPS = 2,000 / 204 = 9.8, almost 10 transactions per second—much better than Bitcoin. Led by Vitalik, the Ethereum Foundation is working on the sharding approach, targeting at increasing TPS ...
