 Introduce two new restrictions retroactively from genesis:
 
-1. Consider any transaction invalid, where the nonce exceeds `2^64-1`.
+1. Consider any transaction invalid, where the nonce exceeds or equals to `2^64-1`.
 2. The `CREATE` and `CREATE2` instructions to abort with an exceptional halt, where the account nonce is `2^64-1`.

+4. The reason a transaction with nonce `2^64-1` is invalid, because otherwise after inclusion the sender account's nonce would exceed `2^64-1`.

 ## Backwards Compatibility
 
 While this is a breaking change, no actual effect should be visible:
 
 1. There is no account in the state currently which would have a nonce exceeding that value. As of November 2020, the account `0xea674fdde714fd979de3edf0f56aa9716b898ec8` is responsible for the highest account nonce at approximately 29 million.

+2. go-ethereum already has this restriction partially in place (`state.Account.Nonce` and `types.txdata.AccountNonce` it as a 64-bit number).
