Ravencoin Mempool Guide: Predicting Transaction Confirmations

When it comes to accepting payments using Ravencoin (RVN), you have two options: you can choose to only accept confirmed transactions on the blockchain, or you may consider accepting both confirmed transactions and certain mempool transactions.

Opting for confirmed transactions provides a high level of trust and security, as these transactions are already a part of the blockchain. However, the downside is that it can take a minute or two for a transaction to be confirmed, which might not be ideal for applications requiring instant access or services that demand a super-snappy user experience.

In situations where you want user interactions to be brutally fast, such as allowing visitors to pay a small fee, say 10 RVN, to instantly unlock and read an online article, mempool transactions become essential.

In this article, we’ll show you two straightforward checks to ensure your mempool transactions are trustworthy and reliable, so you can provide that super-snappy user experience.

1. No Dependencies on Other Mempool Transactions: It’s crucial that a transaction doesn’t depend on other unconfirmed transactions. You can easily check this with the getmempoolentry remote procedure call, reviewing the “depends” attribute. If the “depends” attribute is empty, it means the transaction isn’t relying on any other unconfirmed transactions, making it more reliable.
2. Verify the Transaction Fee: Verify the transaction fee to ensure it’s reasonable and likely to be accepted by a miner. You can compare the transaction fee with the estimated fee from the estimatesmartfee RPC call.
