Title: How to make coinbase transaction of the Bitcoin Genesis block spendable ? Post by: someshwar on June 04, 2015, 12:35:47 PM Because of some quirk in the implementation, the Genesis block coinbase transaction can not be spent.
Can anyone point where in the code this quirk is ? and how to make it spendable. bitcoind, bitcoin. Thanks Title: Re: How to make coinbase transaction of the Bitcoin Genesis block spendable ?

There may be multiple places, but here's a specific test for it:https://github.com/bitcoin/bitcoin/blob/master/src/main.cpp#L1785 and how to make it spendable. You can't - you can try and fail, though :)Title: Re: How to make coinbase transaction of the Bitcoin Genesis block spendable ?

Start reading here:http://www.reddit.com/r/Bitcoin/comments/1nc13r/the_first_50btc_block_reward_cant_be_spend_why/cchdhrm FWIW, the bitcoin wiki has that line about it being a "quirk" Quote from: https://en.bitcoin.it/wiki/Genesis_block The first 50BTC block reward went to address 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa, though this reward can't be spent due to a quirk in the way that the genesis block is expressed in the code (this may have been intentional). Also the reddit page you linked to is interesting, but it doesn't really have anything about the motivation (from what I saw). It seems to me that it may have indeed been a "quirk". What did I miss?

Anyway, thanks for the clarification. I guess Satoshi has plenty of spendable bitcoins if he ever wanted to actually do that. |
