Quest: Blockchain Explorer Introduction

As mentioned before, the blockchain is a public database.

000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f

Use the Block-Chain Explorer to find the transaction where the "Genesis Block" was created. Notice that the Blockchain Explorer finds two transactions with that address.

One in the Bitcoin blockchain, and another in the "Bitcoin Cash" blockchain.

Bitcoin Cash is a "Fork" of the original Bitcoin blockchain, it shares all history up to certain block, where a group of miners decided to continue working on another blockchain.

The other blockchain has no value in the bitcoin network, it is a separate cryptocurrency. The Genesis block in Bitcoin is this one:
