Recently I noticed that Difficulty in genesis block is defined as 131072 in yellow paper. It is different as 17,179,869,184 in mainnet. Anyone knows why two are different?

This has been fixed in the last release of the yellow paper (BERLIN VERSION fabef25 – 2021-12-02).

According to the yellow paper :

yellow paper : equation 41

with H_i being the block number.

For the genesis block (H_i = 0), the difficulty is effectively equal to 2^34 = 17,179,869,184.

However, I do not know where this incorrect value of 131,072 comes from. Anyway, great find!
