- Eth2.
- PoW -> PoS. Validators will have to stake 32 ether.
- Sharding. The beacon chain is the primary chain, and there are 64 shard chains that run in parallel. Each node only needs to run one shard chain. This parallelizes the network, allowing more transactions (from 15/s to 100k/s) The beacon chain makes sure the shard chains settle and sync properly.
- “Docking” is when the current eth blockchain becomes a shard in eth2. An important step on the roadmap. This is phase 1.5.
- Some believe we may finish at 1.5 and not go full sharding of phase 2. Vitalik’s thoughts: https://ethereum-magicians.org/t/a-rollup-centric-ethereum-roadmap/4698. Basically, rollups will be so prevalent that we won’t need full phase 2.
- 2 hour anti-PoS talk: https://www.youtube.com/watch?v=trwhWsKm3Qs.
- Remember PoW punishment for mining an invalid (and ultimately rejected) block is not explicit (you’re not charged) but implicit (you wasted your hashrate). Sure, it’s a self-incentivizing system. But that’s just waste. Is PoS, punishment is explicit. Your stake is slashed.
- PoW has an easier time in the earlier days of the blockchain. Anybody can start a node and begin mining. Fairer distribution. PoS requires stake, which requires that somebody send it to you. It all starts with 1 account, then doles out from that actor.
- A 51% attack on PoW mean slip to 49% if more people bring up more miners. This is more resilient than PoS, which is static if some group gets 51% of the token. It’s over.
- Overall: sure, the points are valid for bitcoin stay better on PoW. But others are more efficient on PoS.
