Crypto 101: Layer-2
What on Earth is Layer-2? 🌍
If blockchain is a superhero, then Layer-2 is like its sidekick(s). It performs much of the ‘heavy’ lifting off-chain (off the main blockchain), making things run smoother, faster, and cheaper.
Superman can’t stop Doomsday and bad guys in the world at the same time – the Justice League takes on all the ‘other’ stuff going on.
