Bitcoin mempool fees

The blockchain has limited space. Like a traffic jam, the transactions move more slowly when the lanes are filled. Graph of Bitcoin mempool growth over six months The number of transactions that are waiting in line to be accepted by the network has ballooned significantly over the last couple of months, as the above graph shows. Attaching a higher fee to your transaction will likely get it through faster because miners have more incentive to include more profitable transactions in the blocks they mine.

These fees also promote a healthier and more secure network because they pay miners and encourage them to participate in the process. These miners are an essential part of Bitcoin's security behind the scenes. Luckily, there are ways to cut down on the costs, if you're patient enough to learn how the Bitcoin blockchain works and the right tools to use. Option 1: Wait it out If you have time on your side, there are a couple of options to consider.

Look for a time when the blockchain is less congested. On the weekend, for example, businesses are closed and fewer overall transactions are made. This gives transactions a little more space to clear. Alternatively, try sending your transaction with a smaller fee, then wait until it clears. The price continues to slide down from there if you're willing to wait even longer. Most do but some don't, so just make sure the wallet you're using supports setting custom fees.

Also, note that this strategy can be a little risky. If your fee is too low, the transaction could get stuck temporarily or won't go through at all. If you're worried about this scenario, you can check a site like mempool. The site shows fee suggestions for low-, medium- or high-priority transactions. The higher-priority fees will push the transactions through faster. But if you aren't in a rush, you can choose a lower fee and wait for it to be included eventually.

In addition, under the "purging" header, mempool. But, again, only some wallets support the feature, including Blockstream Green and Electrum. Option 2: Lightning to the rescue Developers have long anticipated the scenario of rising transaction fees as more users swarm to Bitcoin. That's one reason they're building the Lightning Network, a network that sits on top of Bitcoin to allow the network to support more transactions, relieving congestion. This is the best long-term solution for users planning to make several transactions in the future.

With Lightning, the user does need to pay a fee when initially setting up the channel. Although the term was first used by Bitcoin, the mempool has been adopted by the Ethereum network. But essentially, they are all the same thing. In fact, every node comprising a network has its own mempool.

For example, every node on the Bitcoin blockchain has its own pool of waiting transactions. Those individual nodes with their individual pools, together form a collective global pool. How Does the Mempool Work? When you broadcast a transaction, it is sent to a node or nodes that it is connected to. Then, if everything checks out, the nodes will pass this transaction on to all the other nodes they are connected to, and so on and so forth, with each node adding it to its memory pool, waiting for a miner to come along and do its thing.

The signed transaction is broadcast to a node on the blockchain Ethereum, Bitcoin, etc. The node will check and validate the transaction, adding it to its mempool and broadcasting it to its peers. Each node that receives the transaction will do the same, replicating the transaction across the network.

Some of these nodes will be mining nodes, which will add the transactions to a block and then compete to solve the hash of the block to be the one to add it to the blockchain. Once a miner is successful and the block of transactions is added to the chain, the new block is broadcast back across the network. All the nodes receive the new block and can see the included transactions. If they have any of those mined transactions stored in their mempool, they are removed.

The size of available memory will depend on the individual node. Although the default mempool size is MB, each node will have its own rules for which transactions it allows into its own mempool. A node with a smaller or larger mempool may drop transactions earlier or later which results in differing mempool sizes.
