🔍 Technical principles | Mempool
· Key points: Bitcoin Core’s default maximum mempool size is 300 MB. By default, a transaction can remain in the mempool for up to 336 hours (two weeks), after which it is removed.
· Why: While a transaction is still in the mempool, it hasn’t been added to the blockchain and may still be replaced or removed before it is included in a block.
· Practical tip: When receiving a payment, if you only see that the transaction has entered the mempool and is still unconfirmed, don’t release the goods yet: an unconfirmed transaction can still be replaced.
