Where is stored a full data set of bitcoin blockchain?

Is ../blocks/ dir contains a full data for blockchain work?

I know that ../chainstate/ and other files truly contains service information, include hashes, UTXO data set and others. But is it true that the full information already is in ../blocks/ dir?

I will add an answer to this post

  • chainstate: Container the information about the UTXO and this is by default indexed in a level db.
  • blocks: Contains all the data related to the blockchain, so you can build your own chain state with just scan this file (blkXXXX.dat) one by one
