October 27, 2019 Ethereum’s Devcon conference concludes with new proposals and renewed discussion.

The event has offered industry observers a clearer understanding of upcoming changes and sparked discussion over new proposals. Notable details include: Ethereum 2.0 will exist as a separate blockchain for several years before being fully merged with the original chain. Transfers of ETH between chains will likely be disabled, as they pose security risks, yet proposals for ‘two-way bridges’ to secure transfers are under discussion. The way that state is stored will change; Ethereum 2.0 is designed to be stateless, a choice impacting dApp costs and incentivizing new markets for storage. Dapp developers will also need to prepare for asynchronous communication standards, as transactions will no longer execute atomically. Finally, Vitalik Buterin, who wrote four blog posts during the conference, has proposed launching Ethereum 2.0 with 64 shards, rather than 1024. Collin Myers, head of global product strategy at Consensys, analyzed the economic implications of theses changes, concluding, among other things, that the reduction in shards would reduce the network’s complexity but increase the costs and power of validators, given likely greater hardware requirements.
