Timestamp any item info in a bitcoin (regtest) node and track timestamp info with data integrity. System implemented in python3 & flask and deployed via docker.

Hosted bitcoin regtest with default node and miner node. On docker deploy:

• Start bitcoin regtest default node
• Start bitcoin regtest miner node at /root/miner
• Generates 1 Block by default node to get 50BTC
• Generates 103 Blocks so that bitcoin distributes mined BTC
• Start cron job that mines 3 Block every 10sec
• Init db and Create flask app @ 0.0.0.0:8080
• Start OpenTimeStamps server

OTS Usage

• Start container with bitcoin daemon

    docker run -d --name otscontainer ots
  

• Access otscontainer bash

    docker exec -it otscontainer bash
  

• All task is done within container

• Open multiple otscontainer bash instance each for OTSserver, OTSclient and bitcoin-cli

• Start miner daemon

    bitcoind -datadir=/root/miner -daemon
  

• Accumulate some coins in admin node

    bitcoin-cli generate 101
  

• Start OTS local server on one bash (inside )

    ./otsd --btc-regtest --btc-min-confirmations 3 --btc-min-tx-interval 60
  

• TimeStamp FILE in another bash

    ots --wait --verbose stamp -c http://localhost:14788 -m 1 FILE
  

• Generate Blocks for timestamp in third bash using miner account

    bitcoin-cli -datadir=/root/miner generate 3
  

• Upgrade if --wait is not used (sync bitcoin chain)

    ots --btc-regtest -l http://127.0.0.1:14788 upgrade FILE.ots 
  

• Verify Timestamp

    ots --btc-regtest -l http://127.0.0.1:14788 verify FILE.ots
