The mean size (in bytes) of all blocks created that interval.
Mean Block Size (in bytes)
Only mainchain (non-orphaned/uncles) blocks are counted.
For chains that use median time, the day is defined using it, otherwise, it’s defined using the block’s timestamps.
This metric is not available for all assets, as some node’s RPC API do not expose the size of the blocks.
Released in the 1.0 release of NDP
Mean block size is somewhat arbitrary; block count multiplied by mean block size gives you the total data throughput on a blockchain per day. Blockchains with shorter interblock times will often have smaller blocks but may throughput more data than their higher-latency peers.
