Hi everyone.

Today I wrote some science fiction. Here someone "solved" genesis block. I mean that someone get block with hash consists of zeros. That created a loop in chain and new life  Cool.

Here we have genesis block header:
Code:
01000000 - version
0000000000000000000000000000000000000000000000000000000000000000 - prev block
3BA3EDFD7A7B12B27AC72C3E67768F617FC81BC3888A51323A9FB8AA4B1E5E4A - merkle root
29AB5F49 - timestamp
FFFF001D - bits
1DAC2B7C - nonce

For example someone get block with hash
Code:
0000000000000000000000000000000000000000000000000000000000000000

What will happen? It will become genesis block and loop the whole chain?

More general: What will happen if someone mines block with ANY existing in chain hash?
