it is wired
I thought that blk000XX.dat files are similar in each node, but it is not!

this is old one
$ ll blocks/blk00000.dat
-rw------- 1 srg srg 134215966 Apr  5 16:03 blocks/blk00000.dat
$ sha256sum blocks/blk00000.dat
2b41358fac62f7bf20a29dfa5761bbd39fa4f5e4ca8874cd15982abf1b7d0f42  blocks/blk00000.dat


and I restarted process from the scratch
$ ll blocks/blk00000.dat
-rw------- 1 srg srg 134214783 Apr  2 05:45 blocks/blk00000.dat
$ sha256sum blocks/blk00000.dat
a49e3196378bcd5fa59f53a7b568684fcdd4c626445deda127e5933122008765  blocks/blk00000.dat


any ideas why?
