How to run an dockerized Alephium full node

Supply-chain attacks are quite popular these days, as the Solarwind hack highlighted. Don’t trust blindly containers, and run sanity checks on your environment(s)!

Running a full node in 10 seconds Alephium Wiki provides some guidance on how to run a full node in the testnet.

Cross compile Ethereum for Docker and ARM

Supply-chain attacks are quite popular these days, as the Solarwind hack demonstrated. My advise is don’t trust blindly containers, and run sanity checks on your build environment!

Memory flashing in progress… What’s left is stacking, wiring and firing up!
