Blockchain.info didn't hear about the transaction until it was mined. Blocktrail saw it an hour earlier. I can't see a difference in the inputs / outputs.

For some reason, the transaction wasn't propagated fully around the network. Nodes likely rejected it because of the fee (the fee is small for so many outputs!). Blocktrail heard about it over the p2p network, whereas blockchain didn't look at it until a block was published including the transaction.

Nodes have a strong incentive to listen to blocks, but the mempool is now limited on nodes. You can't expect every node to see every transaction before it's mined.

Can you elaborate how to decode blocktrail transaction hash.

I am not that technically advance. I know about blockchain address transaction but not hash tx. I mean how to see this

and identify exactly which transaction took place
