What is Bitcoin? - Peer to Peer payment network -
Decentralized currency - Digital gold - Money of internet - Internet of money
Bitcoin Advantages - Decentralized - Distributed - Fast - Cheap

None
Bitcoin Disadvantages - Expensive - Slow - Limited to few
txs per second (1MB blocks)
Scaling!
Onchain Scaling BBigger blocks - Bitcoin Cash Advantages - easy
to implement - easy to use - cold storage & HW wallets Disadvantages - Network centralization - No instant transactions - Not solving scaling, postpones it - High fees
Sidechains Another blockchain two-way pegged to Bitcoin (eg. rootstock) Advantages
- Any sidechain functionality with Bitcoin (eg. smart contract) - Cold storage & HW wallets Disadvantages - 2-way peg is not solved yet - No instant transactions - Fees
Lightning Network
Advantages of Lightning Network - Instant transactions - Almost no
fees
Disadvantages of Lightning Network - Requires running node with money
(no cold storage) - Requires monitoring network for frauds - Requires invoice to receiving money - Payment routing is not been solved properly yet
How LN works - Two nodes create channel (Bitcoin TX),
with capacity of x BTC. - Updates channel states many times they want - Close channel (Bitcoin TX)
Implementation of Lightning Network - LND (Lightning Labs) - C-Lightning
(Blockstream)
Demo
Clients of Lightning Network - Zap (Desktop) - Bitcoin +
Lightning Wallet (Android)
None
Summary - LN is still in early stage - Many
people working on - Concept seems to be working - Have a fun with LN
