🔗 Regtest docker environement with electrs and mempool

• install docker

🔗 see https://docs.docker.com/engine/install/ubuntu/

• setting up a regtest environment in docker + mempool instance curl https://getnigiri.vulpem.com | sudo bash # see https://nigiri.vulpem.com/#install sudo nigiri start xdg-open http://localhost:5000/
• This creates
  • esplora localhost:3000 electrs localhost:50000
  • and a gui block explorer at http://localhost:5000
• Setup mempool instance sudo apt install docker-compose git clone https://github.com/ngutech21/nigiri-mempool.git

pushd nigiri-mempool sudo docker-compose up -d sleep 10

🔗 this is needed because the database needs time to start up

sudo docker-compose up -d popd xdg-open http://localhost:8080/

🔗 if the mempool is endlessly loading, then get the debug output with

sudo docker-compose logs -f mempool-api

• this opens a mempool at http://localhost:8080/

🔗 개인정보 보호정책

This program uses by default

• the electrum/esplora server of blockstream.com to fetch blockchain data
• fetches mempool fee information from mempool.space

You can specify your own (personal) server for both in “Network settings”.

When enabeling the Sync&Chat feature default relays are used to transmit encrypted data to your approved trusted devices. You can specify your own relay(s) in the Sync&Chat settings.

This program will not transfer any other information to other networked systems unless specifically requested by the user or the person installing or operating it.
