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
