Weekend Project to tinker with Blockchain and Transactions
I wanted to host different cryptocurrency full nodes running on the testnet's with wallets enabled on my raspberry pi's:
- node1: bitcoin
- node2: litecoin
- node3: dogecoin
- node4: dash
- node5: groestlcoin
Then when all of them were synced (with 2GB pruned to save disk space) create wallets and addresses for each cryptocurrency, then start cpu mining using generatetoaddress and build up some funds.
During this process I interacted with the json-rpc interface and used Pushgateway and Prometheus, to graph dashboards on Grafana of the incoming balances over time as well as the current balances:
After that I interacted with the walletnotify option to notify myself everytime I get a incoming transaction, where the flow would be:
- Wallet notify captures the transaction id with
%s - Python script interacts with the blockchain to determine if the tx has more than 2 confirmations
- Once it has enough confirmations, I get the info such as amount, balance, etc then I log it to MongoDB
- Once I have written the transaction details to MongoDB I send myself a notification on Pushover on my phone
- I then decided to develop a small Python Flask WebUI that pulls the information from MongoDB
More information on how i've setup these nodes, scripts and code will be published to this repo.
