The earlier the transaction is submitted and the higher the fee, the higher the  priority. In addition, some blockchain systems also adopt consensus mechanisms such as Proof of Stake (PoS), where nodes holding more tokens have higher stakes, thus their submitted transactions have higher priorities."}]}],"pr":"1e4d3a9524d61d97b48821bf6caf530e08620c1fc92bc098cd45bb518e9fa3cc"}
