<p>I understand that each node is different and will have a different mempool (and size). But in looking at <a href="https://tradeblock.com/bitcoin/" rel="nofollow noreferrer">https://tradeblock.com/bitcoin/</a> it is showing a mempool size of around 20MB (<a href="http://bitcointicker.co/networkstats/" rel="nofollow noreferrer">http://bitcointicker.co/networkstats/</a> shows similar mempool size of 20MB). But <a href="https://blockchain.info/charts/mempool-size" rel="nofollow noreferrer">https://blockchain.info/charts/mempool-size</a> is showing a mempool of 103MB (<a href="https://jochen-hoenicke.de/queue/#24h" rel="nofollow noreferrer">https://jochen-hoenicke.de/queue/#24h</a> showing similar 100+ MB size). Neither site explains how they configure their mempool. tradeblock.com and blockchain.info are referenced from many sources - do you know what can explain this big difference in how they report mempool size? thanks</p>

But in looking at <https://tradeblock.com/bitcoin/> it is showing a mempool size of around 20MB (<http://bitcointicker.co/networkstats/> shows similar mempool size of 20MB).

Nodes have different policy about accepting transactions to mempool. Some nodes accept all transactions, others accept only transactions with a fee greater than 10 satoshi per byte for example.

Nodes have different policy about droping transaction from mempool. Some nodes drop one-day-old transactions, other nodes drop three-days-old transactions.

Nodes have different policy - this is the answer.
