I know that UTXOs are stored in chainstate database.

But how can I get them in simple txt view? Not balances, but each UTXO.

With vanilla Bitcoin Core, there is no efficient way to do this.

I see two options:

a) Slow and very inefficient RPC loop (not recommended)

  1. Get the genesis block hash (RPC getblockhash 0)
  2. Get the block with all transaction (RPC getblock <hash> 2, 2 stands for verbosity with transaction)
  3. Loop through all transactions and all its outputs, call gettxout <txid> <n> (where n is the outputs index)
  4. If gettxout returns an object, the output is unspent (UTXO), dump it to a text file

This may take a couple of hours or days (depending on your machine).

b) Fast way by patching Core (0.17.1)

  1. Change the code of the function call GetUTXOStats(), apply a text file dump in the utxo set loop (while (pcursor->Valid()) {)
  2. Compile
  3. Call RPC gettxoutsetinfo and let your added code dump data per UTXO to a file (or similar)

https://github.com/in3rsha/bitcoin-utxo-dump seems to work well too, if you don't want to patch Bitcoin Core.

As per README, once you've fully synced the blockchain, quit the Bitcoin server and run:

sudo apt install libleveldb-dev
go get github.com/in3rsha/bitcoin-utxo-dump
bitcoin-utxo-dump -db /path/to/.bitcoin/chainstate/

This produces a large utxodump.csv file with about 8GB size (about 2x the chainstate/ directory size) in 14 minutes when I tried it, with format:


Here's a quick script to import that CSV into sqlite3 which is more manageable:

echo | sqlite3 utxodump.sqlite3 \
-cmd 'CREATE TABLE utxo(
  count INT,
  txid CHAR(64),
  vout INT,
  amount INT,
  type CHAR(12),
  address CHAR(34)
)' \
-cmd 'CREATE UNIQUE INDEX utxo_txid_vout
  ON utxo(txid, vout);' \
-cmd '.mode csv' \
-cmd '.import utxodump.csv utxo'

I used that here BTW: https://github.com/cirosantilli/bitcoin-strings-with-txids/tree/7e95546479508e9fe5158dad6bc8601e2b4e02ee#utxo_nonstandard to try and find unspent puzzles that I might be able to solve, but I didn't :-(
