 .Scaling Blockchains

 The side effects of increasing the block size or decreasing the block time with respect to centralization of the network are severe as a few calculations with the numbers show.
-Let us assume the usage of Bitcoin grows so that the network has to process 40,000 transactions per second.
+Let us assume the usage of Bitcoin grows so that the network has to process 40,000 transactions per second, which is the approximate transaction processing level of the VISA network during peak usage.

 Assuming 250 Bytes on average per transaction this would result in a data stream of 10 Megabyte per second or 80 Mbit/s just to be able to receive all the transactions.
 This does not include the traffic overhead of forwarding the transaction information to other peers.
 While 10 MB/s does not seem extreme in the context of high-speed fiber optic and 5G mobile speeds, it would effectively exclude anyone who cannot meet this requirement from running a node, especially in countries where high-performance internet is not affordable or widely available.
