chainpoint2ots

This web app allows to convert Chainpoint 2 proofs to OpenTimestamps proofs, with a simple drag 'n drop. It is provided as a Web UI and a Node.js micro service (which is a wrapper around conversion code from https://github.com/opentimestamps/convert2ots.git).

Run using Node.js

Install dependencies:

npm i

Run:

OTS_USE_BITCOIND=false node .

Run using Docker

Build:

docker build -t chainpoint2ots .

Run:

docker run --rm -p 3000:3000 chainpoint2ots

Configuration

The OTS_USE_BITCOIND environment variable must be either "true", "false" or "strict".
If set to "true" or "strict", OTS_BITCOIND_RPC_USER and OTS_BITCOIND_RPC_PASSWORD must be defined.
OTS_BITCOIND_RPC_PORT and OTS_BITCOIND_RPC_CONNECT can optionally be set (respectively defaulting to 8332 and 127.0.0.1).
If not set to "strict" the converter will (in case of failure) fallback on third party services instead of your bitcoin node.

You can set the OTS_HTTP_PORT environment variable to listen on a specific port (default is 3000).

Example:

docker run -d --rm \
    --name chainpoint2ots \
    -e OTS_HTTP_PORT=7890 \
    -e OTS_USE_BITCOIND=false \
    -p 80:7890 \
    chainpoint2ots

OTS_HTTP_PORT=7890 OTS_USE_BITCOIND=true OTS_BITCOIND_RPC_USER=bitcoinrpc OTS_BITCOIND_RPC_PASSWORD=test node .
