How do Resource Credits work on the Hive blockchain? Since transacting on the Hive blockchain has zero fees, transaction rate-limiting is employed to safeguard the blockchain from spam attacks. Everything action that you take on the blockchain will consume a small amount of Resource Credits. This includes posting, commenting, voting, transferring tokens, etc. Viewing content does not consume Resource Credits.

Every user has a limited amount of Resource Credits to use each week. The more transactions a user does, the less Resource Credits they will have left (until they recharge). Users with more Hive Power will have more Resource Credits.

When the blockchain becomes busy (due to heavy use), the Resource Credit cost of transactions may become higher than during times when the blockchain is less busy.

If users do not have enough Resource Credits, they will be unable to transact with the blockchain until their Resource Credits recharge or they acquire additional Hive Power to increase their Resource Credit balance.

If you get an error that you have exceeded your Resource Credit allowance, it is normally best to just wait and try again later. Usually if you wait and try again later, the transaction will go through.

If you are unable to transact for extended periods of time, or you are frequently running into Resource Credit limits, then you will either need to reduce your usage to stay within your limit, or purchase more Hive Power for your account.
