I was thinking more on the process for these transactions.
I assume that the process is
- sidechain miner broadcasts transaction with OP_BRIBE output
- this transaction ends up in the memory pool of miners
- Miners add the transaction to their next block
- Miners add a transaction which spends the output to one of their own
addresses
I think you need an additional rule that OP_BRIBE checks fails unless the
output is locked 100 or more blocks.
The output script would end up something like
IF
<block height> <chain_id> <critical hash> OP_BRIBE_VERIFY
ELSE
<public key> OP_CHECKSIG
ENDIF
This output acts like "anyone can spend" for the one block height.
Otherwise, only the sidechain miner can spend the output.
This allows the sidechain miner to reclaim their coins if the transaction
ends up in a different block.
OP_BRIBE_VERIFY would have an additional rule
The script to fails if
one or more of the transaction outputs start with something other than
the template
<block height> does not match the block height, or
<critical hash> is not the hash for the sidechain with <sidechain_id>, or
there is no hash for that sidechain in the block's coinbase
The template is
<100> OP_CHECKSEQUENCE_VERIFY
