Some of you may know that we encountered several difficulties with the blockchain in the last days/weeks: we regularly had fork of the blockchain while we were only 3 nodes of network.
After a long investigation, I’ve discovered why exactly this issue happened: this is due to a wrong protocol rule leading to an unstable common difficulty level.
Fixing this rule is OK, however, **it involves that 40% of the blockchain is no more compliant** with last protocol rules. Precisely, block #2060 and following are to be rewritten.
**Concretely** , all transactions from this block and after will be erased. Same for certifications:
@Folaht --\> cgeek, mhugo, galuel, ManUtopiK, kimamila, toearc
@Galuel --\> inso, vit
I will personally rewrite the blockchain from block #2060 to today’s blocks, it will probably be done _in 1 or 2 days_.
Sorry for this data loss, but at least, this testing currency is making its job: this (important) bugs has been discovered & fixed! 😌

Blockchain has been written successfully on [http://twiced.fr:9101](http://twiced.fr:9101).
You may reset your blockchain & sync again.
