Hi @ivanli,

First of all i must tell you i am new addition to this beautiful world #steemit. Secondly i would like to say that your way of writing is exceptionally odd in a very positive way. It always attracts the readers and so it did with me.

You are introducing a new term Stale Blocks in a very systematic way.

Keep sharing such excellent things in the form of your supreme knowledge.

Stay Blessed and wish you a very very Happy New Year in Advance :)))
