Bitcoin-QT.  My blockchain failed.  I started rebuilding roughly a month ago.  Win7.  The system seized once a week ago, I restarted and it continued reindexing no problem.  Last night I was within a few of days of sync and expected to be up to date today.  I woke up this morning to BSOD.  I rebooted and the blockchain has failed with "Corruption: error in middle of record" log notation.  There doesn't seem to be any obvious problem in the chainstate directory.

I had run two copies of the Bitcoin-QT for years.  Mining got unprofitable so I shut one down as I needed that machine for other work and still do.  Also I moved my bitcoins to an online wallet.  The one copy I kept running would wake up and run a few hours every night then shut down.  I felt it was good for Bitcoin to keep running a blockchain and who knows I might someday need to send a signed message.  Now this.  

Reindexing the blockchain almost made the machine unusuable, slowing it down and using resources.

It's as if the developers don't want common users to have a blockchain copy.

There really should be an option to delete x weeks of blocks.

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

Signing a message does not require a caught up blockchain.

There is.

Use blockchain pruning.
