Blockchain reminder: transactions
When we make one transaction en Bitcoin or in any other cryptocurrency, its authenticity needs to be validated. In this way, the network ensures that the transaction is valid and that it is processed reasonably. Those responsible for this are the miners or the network participants (in case of networks PoS, DPoS o PoA). They are paid a small fee (transaction fee) for the work of validating the transaction made.
But due to the blockchain working mechanism, there are times when the mining fee may be higher than the actual amount of the transaction. This is related to the concept of inflation. And is that, if there is a high demand for transactions, and there is little capacity to meet it, the transaction fee increases. This is caused, because the miners will request a higher payment to prioritize and attend to the transactions quickly.
