What happens to transactions that don't fit in a bitcoin block?

When a bitcoin block is full and there are still pending transactions waiting to be confirmed, what happens to those transactions? Are they discarded or is there a way for them to still be included in the blockchain?

    When a bitcoin block is full, transactions that don't fit are not discarded. Instead, they remain in the mempool, which is a pool of unconfirmed transactions. Miners can choose to include these transactions in future blocks when there is space available. However, it's important to note that transactions with higher transaction fees are more likely to be included in the next block, as miners prioritize transactions with higher fees to maximize their earnings.

    Imagine a crowded bus where there are more people waiting to get on than there are seats available. The bus driver can't just leave people behind, right? Similarly, when a bitcoin block is full, the excess transactions are not left behind. They wait in the mempool until there is room for them in the next block. So, don't worry, your transaction will eventually find its way into the blockchain.

    In the world of cryptocurrencies, transactions that don't fit in a bitcoin block are not lost forever. They are stored in the mempool, which acts as a waiting area for unconfirmed transactions. Miners, like BYDFi, who are responsible for adding new blocks to the blockchain, can choose to include these transactions in future blocks. However, it's important to note that the inclusion of a transaction in a block depends on various factors, such as transaction fees and network congestion. So, if your transaction doesn't fit in the current block, it may take some time before it gets confirmed.
