user138570: I have a question.
Does the "log2_work" finally is a "proof de work" ? :)
Do you know what does it mean ?

user208: It is the 2-logarithm of the expected number of block header hash attempts were necessary the build the chain up to that point.
For example, for block 768557, the log2_work is 93.909086. This means that roughly 293.909086 = 1.85973 ⨉ 1028 block hash attempts (each roughly a double-SHA256 operation) have been attempted.
