At June 17, 2016, the attacker found a loophole in The DAO's smart contract. With a new smart contract, the attacker was able to drain most of the funded ETH into a child DAO called "The Dark DAO".

The event created great turmoil in the Ethereum community, which forced the community to act within 28 days, otherwise the funds would potentially be lost. The community acted and with strong consensus and opted for a hard fork.

While most people were happy, others felt that the immutability of the network was compromised. Out of that philosophy, the Ethereum Classic project was born, a project that would keep the original blockchain alive.

The attack as it unfolded.

Creator of the malicious DAO: 0x4a574510c7014e4ae985403536074abe582adfc8

Start of the drain: 2016–06–17 03:34:48 UTC, block 1718497
The malicious child DAO aka “The Dark DAO”:0x304a554a310c7e546dfe434669c62820b7d83490
Malicious token holders aka “Dark token holders”.
These are the accounts that control the malicious DAO:
0xc0ee9db1a9e07ca63e4ff0d5fb6f86bf68d47b89 0xf835a0247b0063c04ef22006ebe57c5f11977cc4
Curator of the malicious DAO and creator of the malicious proposal: 0xb656b2a9c3b2416437a811e07466ca712f5a5b5a
The malicious proposal from which the attack was launched:
#59, aka “lonely, so lonely”, 2016–06–08 05:38:01 UTC, before the recursion call bug went public on 2016–06–10
Voted Yes (same as the malicious token holdes):

0x347c28ef5487b37a8e03040653a739f19b986b2d
Recipient as stated in the malicious proposal (same as curator): 0xb656b2a9c3b2416437a811e07466ca712f5a5b5a

The Dark DAO address T0x304a554a310c7e546dfe434669c62820b7d83490 is, of course, empty on the forked chain as this was the whole point of the fork.

That statement is now true for the Ethereum classic chain (the unforked chain.)

This can be verified by checking the address http://gastracker.io/addr/0x304a554a310c7e546dfe434669c62820b7d83490

However, there is no useful block explorer currently available for Ethereum Classic so a more detail investigation where the funds have gone is up for developer to take a deeper look at.

Does this prove that the Ethereum community made the right choice?
