TL;DR We found some challenges porting high-value applications built in Solidity to PolkaVM. Therefore we are considering deploying an EVM stack on Polkadot Hub as soon as possible after launching the preview version of our Ethereum-compatible PolkaVM stack on Hub, so that we (Parity, W3F, and BD pa…

[image] Jan-Jan: developers can choose to retarget PolkaVM to make it cheaper for their users and save on infra Is there a clear plan on how this porting process (EVM => PVM) will look like, and are there any limitations to this? For example, will it be possible to easily port state, balances…

I’m happy that Parity has finally come to its senses. A lot of opportunity costs and damages to the ecosystem have already done (especially as previously OpenGov was voting against all other alternative solutions because of revive “the only Ethereum-compatibility solution moving on”). It’s importan…

I’d like to hear the pitch that convinces me that allowing the deployment of this “high value apps”(in other ecosystems) is going to translate in a guaranteed inflow of users in Polkadot. Otherwise it’s just making everything more complex, confusing and creating division with two silos. It’s very im…

It is also important to note that in some cases the PolkaVM bytecode size can even overshoot to 80x the size of its equivalent EVM bytecode . This could make the solution impractical if future improvements to the compiler cannot decrease the final bytecode significantly.

100% yes. PVM and EVM contracts will be able to call each other.

I’d like to point out that the resolc compiler is currently in an MVP state. So far we had the chance to implement only the most basic size optimizations yet. For example 64bit RISC-V support and some basic function outlineing were quick to implement and together more than halved down the baseline c…

[image] Jan-Jan: Differences in gas estimation, and decimals between DOT and ETH. What is the plan for the decimal difference? Masquerade as 18 decimals in the EVM? Also curious why these issues weren’t surfaced much earlier on in this campaign. We could have deployed revm last year and had …

Just had a thought how we can potentially even go below EVM bytecode sizes with PVM contracts and resolc. For example an ERC20 which compiles to 4kb EVM code size (currently 18kb PVM) could be around just 2kb of data. I’ll try to make a working PoC.

In my opinion it would be better to just postpone the deployment until the targeted Ethereum-compatible PolkaVM stack on Hub is fully ready and more performant than other EVM platforms. If it turns out theoretically and practically impossible, then it might be preferable to just shelve the project, …
