I'm sort of surprised that no one has even proposed a hardfork to recover those coins— esp. in light of mtgox somehow losing most of their customer's coins. Smiley
... Huh. Knowing this was accidental, is there any moral obligation to recover lost funds through a hard fork, especially considering the now-victims weren't even the people who "directly" lost it?

Like... some guy accidentally drops $1.7M down a near-bottomless pit, and at the bottom of the pit are some kind of human-controlled robot miners who could bring it up with just a bit of fuss - should the controllers order the robots to bring the money up, or should it just sit there for all eternity because - hey, I'm not the idiot who dropped $1.7m down a pit?

This is a pretty unique situation... almost like we can "print" away the debt - except the coins were always there, just lost.

They were all within a couple hours of each other AFAIK and all by MTGOX.  Am I incorrect?

OH. Smiley
Well you might be right and if that is the case well .... wow!

Well MtGox wasn't the only one to do it.  2609.36304319 BTC over the years due to this single malformed template isn't a small chunk of change.  It just struck me as strange as these 23 outputs represents the majority of the "custom" scripts in the UTXO and they all are the same exact mistake.

Ouc, well MtGox at least MtGox can point to the fact that they weren't the only ones to make this mistake.  A total of 2609.36304319 BTC over the years due to this single malformed template isn't pocket change.  It just struck me as strange as these 23 outputs represents the majority of the "custom" scripts in the UTXO and they all have the same error.

This was MTGOX it made a bit of news back when it happened.

Like most epic failures it took a complex series of events to happen— that transaction was non-standard and wouldn't have been mined by normal nodes... but mtgox had an API to ask eligius to mine transactions of interest to it which bypassed all non-standardness checks and their system flagged those transactions for prioritization.

I'm sort of surprised that no one has even proposed a hardfork to recover those coins— esp. in light of mtgox somehow losing most of their customer's coins. Smiley

Right. He apparently used an empty string instead of a hash160. EQUALVERIFY compares strings, not numbers, so the 20-byte output of HASH160 will never equal the 0-byte OP_FALSE.

In building a UTXO parser I came across a number of high value "custom" scripts and started looking at each of them individually.   They all look like really expensive mistakes.

They all have the same output signature.  Here is a link to the most expensive one (497 BTC)
https://blockchain.info/tx/03acfae47d1e0b7674f1193237099d1553d3d8a93ecc85c18c4bec37544fe386

OP_DUP OP_HASH160 OP_FALSE OP_EQUALVERIFY OP_CHECKSIG

If they indeed are unspendable (which I believe they are because it would require a signature from a pubkey which hashes to zero) and you didn't make one of these 23 txns well the good news is that is 2609.36304319 BTC destroyed, so your BTC are worth a little more.
