Bitcoin miners are mining fewer empty blocks in 2020

In May, Bitcoin recorded its third halving, cutting the per-block subsidy from 12.5 BTC to 6.25 BTC.

With each halving of the block subsidy, transaction fees become a more significant component of miner revenue, thus incentivizing miners to include as many transactions in the blocks they mine as possible. However, even with the expected halving, miners this year were still mining empty blocks.
