Title: Bitcoin Unconfirmed/Pending Transactions Flooding Network
Post by: Moloch on February 28, 2016, 06:58:31 PM
Where are all these unconfirmed transactions coming from? Is there another spam attack right now?

Current count is 18,500 unconfirmed transactions and its climbing fast!

The average fee is 0.07125 BTC per transaction! (seems way too high for an average fee)

Does anyone know what is going on?

At 14.9 satoshi per byte, I experience no flood.

The reason of high fee could be for spam of extremely large transactions.

Seems OK now. Can't say the same for my eardrum after that sound in the link.
 Definitely not a spam attack, just a random spike in transactions.

The mempool has been above 10k transactions quite some time now. This doesn't seem like everyday use, but not like a dedicated spam attack either. If this was an attempt to keep sat/kB fees high it's been quite successful though.

My node has 65k unconfirmed transactions. A little high, but not high enough to call it an attack.

On My node :  5580  Unconfirmed transactions
More than expected, but OK
