solang VS substrate

Solidity is language for smart contacts originally designed for Ethereum. If you want to execute your Solidity smart contract in a blockchain whose VM interprets WASM, then you need to compile Solidity into WebAssembly. Currently, we target Substrate (https://github.com/paritytech/substrate) and Ewasm (https://ewasm.readthedocs.io/en/mkdocs/) that need WebAssembly. This is the project's repo: https://github.com/hyperledger-labs/solang

If you really want to use solidity there is https://github.com/hyperledger-labs/solang , a solidity compiler for Solana. You will still need to learn how to interact with the Solana blockchain but you can do it in Solidity.

I see solang can compile Solidity code to Solana. Can this code be deployed to the Solana blockchain?

You could try to use https://github.com/hyperledger-labs/solang and target WASM.

It should be technically possible as I see there is a solidity to wasm compiler: https://github.com/hyperledger-labs/solang

Substrate — a framework for building application-specific blockchains (written in Rust);

frame-benchmarking = { version = "4.0.0-dev", default-features = false, optional = true, git = "https://github.com/paritytech/substrate.git", branch = "polkadot-v1.0.0" }

To offer some perspective outside of the typical "all crypto is a scam", Parity is doing some cool stuff with a rust modular blockchain library called Substrate https://github.com/paritytech/substrate.

Rust takes the cake in the blockchain space: Substrate, Cosmos (CosmWasm), and Solana. All of the zero knowledge cryptography libraries used for layer 2 solutions are written in Rust, compiling to Wasm (see arkworks, Risc0). Ethereum's next version of smart contracts will even use a restricted subset of Wasm ("Ewasm") instead of EVM.

Verifying NPoS election solution graph and its score is a memory-intensive operation that needs to be performed within a single block time. Under the current runtime constraints, a solution graph with 22,500 nominators can be verified well within the block production time on Polkadot. There are plans to improve on this and implement multi-block election solution verification, after which, the NPoS system can scale to incorporate more nominators.

Fast-unstake is now available on Kusama. This allows instant unstaking if you have not participated in staking in the last 28 eras. https://github.com/paritytech/substrate/pull/12129

First, any outstanding multisig calls (ones where one signatory has signed, but not the threshold) will not be able to execute. Please either finish your multisig calls before this upgrade, or wait until after it is completed. https://github.com/paritytech/substrate/pull/12072
