Нашел блок. но вместо +50btc получил "category":"orphan"
https://en.bitcoin.it/wiki/Block_chain
"Blocks in shorter chains (or invalid chains) are called "orphan blocks", and while they are stored, they are not used for anything. When a block becomes an orphan block, all of its valid transactions are re-added to the pool of queued transactions and will be included in another block. The 50 BTC reward for the orphan block will be lost, which is why a network-enforced 100-block maturation time for generations exists. "

Всё равно не могу понять - из-за чего этот orphan получился. Ведь мой блок даже в blockexplorer есть.
