Transition to PoS Merger Spec Finalized

Ethereum 2.0 has finalized the specifications for a full transition to proof-of-stake (PoS), a so-called merger, according to a developer call. Ethereum developer Tim Beiko said that ETH 2.0 "now has proper specifications in terms of consensus." The specification "started as a Markdown file and evolved into the current Python executable specification," he said. They will likely follow the same approach as ETH 1.0, typically relying on opcode bootstrapping through the core EIP. (Trustnodes)

However, users need to pay some transaction fees (gas) to miners on the Ethereum Ropsten testnet. In addition to this, the V2 testnet also aims to solve some problems of L1 and L2 interaction, slow withdrawals and poor scalability of existing layer 2 Ethereum-based systems. If the operation is stable, ZKSwap will be launched on the main network after this stage of testing.
