Title: Did satoshi mined the first testnet block?
Post by: BlackHatCoiner on November 03, 2020, 01:20:34 PM
According to our wiki (https://en.bitcoin.it/wiki/Testnet) testnet has changed 3 times since version 0.1

The testnet's genesis block gave 50tBTC to 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa which is the same as satoshi's. You can check the testnet's coinbase transaction of block 0 here (https://blockchair.com/bitcoin/testnet/transaction/4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b). Did they do it to honor him? Who continued the bitcoin development in February of 2011 and began the testnet 3?

Well, most of us know that there had been 2 resets of test network in the history of bitcoin due to the insane increase in difficulty of test network.

The first version of testnet was introduced by Gavin himself and you can find the announcement for the same here : TEST network, for experimental development and hacking (https://bitcointalk.org/index.php?topic=363.0).

The second testnet reset was also proposed by gavin on January 30, 2011 in the forum : [RFC] Testnet reset (https://bitcointalk.org/index.php?topic=3051) based on a discussion from the IRC : https://web.archive.org/web/20131201213242/http://bitcoinstats.com/irc/bitcoin-dev/logs/2011/01/30

17:10   slush   gavinandresen: agree, but is there any reason for keeping difficulty so high?

Did they do it to honor him?
Might be. The block explorer lists the genesis block from Testnet 2 since Testnet Mark III was announced only in 2012. You should probably check these 2 PRs regarding this. Here are the pull requests to create new genesis block : #53 (https://github.com/bitcoin/bitcoin/pull/53) and #57 (https://github.com/bitcoin/bitcoin/pull/57)

Who continued the bitcoin development in February of 2011 and began the testnet 3?
gavin and other developers took over the control of bitcoin core development when satoshi left and everyone know about that. Regarding the creation of testnet Mark III, its gavin again :

Announcement for testnet Mark III : https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2012-May/001493.html
PR for Testnet Mark III : https://github.com/bitcoin/bitcoin/pull/1392

There are quite a discussions prior to #1392 which can be seen in the above mentioned PR.

P.S Regarding your topic title : May not be! davout should have been the miner for Testnet 2 genesis block since he was the one who has written the PR for resetting genesis block if I am not wrong.

The first test net uses the same genesis block as bitcoin, that's the first transaction goes to satoshi addy, but for testnet 2 and testnet 3 there were different genesis blocks. So, this doesn't mean satoshi mine it, it's means that was the same Genesis Block.
