- Beacon Chain: it happens to run on the PoS algorithm and thus, acts as an economical alternative to PoW. However, the team does not plan to replace PoW with PoS instantly. In fact, in the beginning, both of these protocols will run in parallel.
- Sharding: Until now, people had to use 3rd parties for sharding on Ethereum. However, this will be introduced as a native feature in Ethereum 2.0, allowing scalability of transactions and facilitating the network to execute more transactions in a given time.
- eWASM: This is the latest EVM where sharding and beacon chain will be hosted. Basically, all of the current and forthcoming upgrades will be integrated and run on this machine.
