How To Build Own Lightning Network in Few "Easy" Steps
- few pieces of paper
- table
- crazy friend/partner/spouse
- some time
Why Lightning Network is Needed?
"Bitcoin doesn't scale"
7 billion people doing 2 blockchain transaction per day
- 24 GB blocks
- 3.5 TB/day
- 1.27 PB/year
Bigger blocks = Centralization
- Very few full nodes
- Very few miners
- De facto inability to validate blockchain
Building Blocks
- simple transactions
- multisig adresses
- time lock
- hash values and secrets
Simple Transactions
