It doesn't exist, eth 2.0 has... Staking at the moment Let me provide some information about Elrond Sharding has advantages and disadvantages. The advantages are obvious: parallel processing and storage splitting. The disadvantages when splitting the network into shards are that the network can be attacked with less resources. Splitting the network in half, the 51% attack becomes a 25%+1 attack in each shard and so on. It is possible to attack multiple shards at once but you need the resources to do this. So how does Elrond solve this? . In order to prevent attacking and malicious behaviour we have created the shards big enough (~800 nodes) so that controlling 2/3+1 from a shard is not that easy. Every epoch (~1day) nodes are shuffled between shards in order to destructure malicious groups. $### million to get 2/3+ 1 in a shard + you would need to replace the validators that are already in, that's without reshuffling that is implemented. There will also be "fishermen" in shards that look for invalid blocks (created by malicious groups that contain maybe double spend transactions) and signal these blocks to the metachain with a proof. Once the metachain verifies the proof the malicious nodes will be slashed (their locked tokens will be in part given to the fisherman and in part burned). Elrond has built a rating system, so that the chances of validators that behave malliciously will be reduced to get to the consensus group and this way having another "check and balance" in its protocol Elrond's VM is called Arwen, wasm based https://elrond.com/blog/elrond-virtual-machine-arwen-wasm-vm The code can be translated from solidity -> rust by hand, Contracts are short, it's not a huge effort. Especially since Rust framework is a lot less verbose and a lot safer. An automatic solidity to Wasm compiler is possible, but it's not something the Devs are working on at the moment as they are very busy with other things ,but anyone is free to give it a go though! Deploying an Ethereum dApp on Elrond is relatively simply - the smart contract logic has to be written in Rust instead of Solidity and deployed to Elrond. One of Elrond devs ported the BUSD stable coin Ethereum smart contract to Elrond in 1 day - writing, testing, deploying, testing some more. It's not automagic, it can't be, but it's average difficulty, at best. So it's quite easy, maybe not for us but for a Dev, yes 😊. The main interoperability will be from the Bridges that are in place, so the possibility to mint - (swap) NFTs, mint ESDTs, and others asset is fully viable. USDC will be the first stable coin bridging over to Elrond, followed shortly after by BUSD, then many others. Keep in mind that eth 2.0 (wen?!) will be moving over to eWASM as their virtual machine, Elrond is already there. It also appears in their roadmap that they are working on auto compilers from solidity to rust
Dammit that's seriously involved Thanks
