SLOT-TO-PING AND ANOTHER DESCRIPTIVE MEASURE FOR BLOCKCHAINS

Summary from the TLDR Crypto newsletter

The slot-to-ping (s2p) ratio is the ratio of the block production time to the time it takes for the block to reach other validators. A smaller s2p promotes centralization, as delays in block production times lead to higher returns by allowing producers to include more blocks. block-bits-per-slot-time against propagation/execution bandwidth must also be considered as it considers block data transfers instead of assuming it is always a tiny fraction of the slot time.
