Why do some transactions not show up in the blockchain immediately?

[Abigaille]

This has happened to me 3 times now! I get a 15 min invoice from Bitpay and I immediately  send a payment from Coinbase or Multibit, but the transactions never shows on the blockchain and the invoice expires. I search the transaction hash on the blockchain.info and I get this error "Sorry we could not find any blocks or transactions matching this hash". I then send a second payment from the wallet and the transactions show instantly on the blockchain!

Why is this is unreliable? Why do some transactions show immediately on the blockchain and other do not? It is VERY frustrating!

Sounds like a bug in MultiBit, but more details would be needed to know for sure.

If such a bug existed in the most recent version of MultiBit, I'd expect a lot more people to be complaining about it, so it sounds like you might be doing something unusual.

It's happened from Coinbase and Multibit.  Here is the FAQ for the Multibit one: https://multibit.org/en/help/v0.5/help_support_sentBitcoinFromMultibitButTheyAreStuck.html


Here is Multibit reasons for a transactions not being broadcast:

There are various reasons why a peer does not relay a transaction. In a rough order of frequency they are:

    There are lots of tiny inputs (under 5432 satoshis) in your wallet and the transaction fires the anti-spam rules.
    The fee is too small and the peer chooses not to relay it.
    The transaction is a double spend. Doubles spends aren't relayed through the network.
    Some other reason - this is not a definitive list.


Mine fit into option 4: "Some other reason - this is not a definitive list"


So basically NO reason???
