On Monday, October 16, at 05.22 UTC on the block 4,370,000 in the Ethereum network, the previously planned hardfork was implemented.

Byzantium's hard work has made the following changes to the Ethereum blockchain:

- delayed the "complexity bomb" for another 18 months;
- speed of blocks confirmation increased;
- Reduced the reward for the block from 5 to 3 ETH;
- added zk-SNARK elements, which are designed to introduce new privacy features, currently found in crypto-currencies such as Zcash;
- expanded the capabilities of the virtual machine Ethereum, etc.

The Metropolis hardfork was first introduced on the Ethereum roadmap in 2015. Byzantium is the first part of a major upgrade of Metropolis. Before activating of Metropolis in thenext year, there will be another second, which will be called Constantinople.

Buterin to Propose Way to Speed Up ETH 2.0 Migration

Vitalik Buterin,creator of Ethereum, believes the eth1 system can exist as a zero shard in eth2

Ethereum founder Vitalik Buterin proposed a solution that allows you to quickly get rid of the Proof-of-Work (PoW) algorithm chain and move everything in Ethereum 2.0 to Proof-of-Stake (PoS).

According to him, the eth1 system can exist as a zero shard in eth2.

Validators who choose to participate in eth1 will be able to register as friendly. They are expected to support the full eth1 node in addition to the eth2 node.

A full eth1 node will load all blocks of the zero shard and maintain the updated state of the old circuit.

Buterin believes that his proposal does not make any changes to the planned procedure for the transition from eth1 to eth2. Only software for stateless clients and witness size changes in the eth1 protocol are required.
