Executing A Smart Contract in geth

Since Binance Smart Chain and more specifically DeFi on BSC are a thing, I’ve been learning the amazing ways of Smart Contracts, and while many documentation exist on this topic, I didn’t find a clear one on how to “simply” execute a Smart Contract on geth, aka Go Ethereum, the most used Ethereum implementation and client.

Geth can interact with the Ethereum blockchain using, well… Javascript, and more specifically an (old) implementation of web3.js.

We will use Bunny Pancake as our DEX example, and more precisely the BUNNY pool smart contract, aka 0xCADc8CB26c8C7cB46500E61171b5F27e9bd7889D.

Ledger Nano On KVM

In order to keep my cryptocurrencies as secure as possible, I only interact with those within a virtual machine located on an encrypted USB stick. I own both a Ledger Nano S and a Ledger Nano X, which connect using USB. Also I don’t use libvirt for this as I want it to be as easily and quickly usable as possible. So here’s the secret formula in order to access those hardware wallets from a GNU/Linux KVM VM via USB pass through:

proof-of-work based blockchain explained with golang

Yet another “blockchain explained” article, I know, I really thought about if releasing it or not, but you know, you only understand what you can explain clearly, so I hope I’ll be able to explain proof of work and blockchain as clearly as it is clear in my mind.
The originality of this post is that I’ll try to make those concepts clear through pieces of code extensively explained so it doesn’t feel like a theoretical expose where you get the idea without the taste.
