Correlation between share difficulty and network difficulty

[🏰 TradeFortress 🏰]

What is the correlation between share difficulty and network difficulty?

Is a share difficulty of 5, equal to a block that would be accepted for a network difficulty of 5 (ie, 1 to 1)?

In a nutshell, yes.  To add a block to the chain, some miner somewhere has produced a share with difficulty of at least the current target (18,736,441,558 right now).  At the end of January last year, that miner would only have had to produce a share with difficulty of at least 2,968,775.

Genesis block (block 0) difficulty: 1
Block 100000 difficulty: 14,484
Block 200000 difficulty: 2,864,140
Block 300000 difficulty: 8,000,872,136
