| # CosmWasm VM - Core product | ||
|

|
|
||
| ## Project Overview :page_facing_up: | ||
|
|
||
| Composable Finance focuses on trustless, cross-chain communications between Polkadot and other ecosystems. | ||
| In this case, a CosmWasm VM is a supplementary component to onboarding a new developer community and a widely adopted smart contract framework. | ||
|
|
||
| ### Overview | ||
|
|
||
| The first CosmWasm VM implementation in Substrate for the Polkadot and Kusama ecosystems. | ||
|
|
||
| CosmWasm, short for Cosmos Webassembly, is a smart contract framework designed for use in the Cosmos ecosystem. | ||
| Originally, the CosmWasm specification was built as a Cosmos SDK module and currently provides a plug-and-play functionality for Cosmos chains. | ||
| CosmWasm was written in half Rust and half Golang (Go), with low-level calls in Rust and high-level dispatching logic, handled in Go. | ||
| The actor model is implemented in Go which then calls the low-level Rust library to execute contracts effectively. | ||
|
|
||
| CosmWasm offers a high degree of customization as part of its design philosophy. | ||
| A key feature of CosmWasm is that it allows for multi-chain contracts; one dApp, one contract, but multiple chains. | ||
| As a result, CosmWasm allows users to benefit from the utility across chains instead of being forced to choose between them. | ||
| Implementing the CosmWasm framework in Substrate will allow developers and parachains in the Polkadot and Kusama ecosystems | ||
| to seamlessly interact with a well-tested and heavily adopted smart contract framework. | ||
|
|
||
| In terms of security, CosmWasm is designed to avoid the attack vectors found in Ethereum and Solidity, such as Reentrancy, and Default Visibilities. | ||
| Its security is further reinforced by its well-developed tooling and testing mechanisms prioritized early in its conception. | ||
| Due to these benefits, many projects have adopted CosmWasm as their smart contract framework, | ||
| including notable examples like Juno, OKX, and Osmosis. | ||
|
|
||
| Overall, the CosmWasm VM proved to be the best VM for our needs as we found it to be the most portable and robust solution. | ||
| CosmWasm was built with interoperability in mind from the very beginning, | ||
| the goal being to build a smart contracting framework capable of operating across multiple blockchains. | ||
| By utilizing the XCMP as a transport layer, | ||
| CosmWasm contracts would be able to communicate with each other on different parachains without the need for any trusted parties. | ||
| The entire Dotsama ecosystem has the potential to benefit from CosmWasm. | ||
| This means that any team building on Dotsama will have unparalleled reach, | ||
| and the potential to create applications that have never been seen before. | ||
|
|
||
|
|
||
| ### Project Details | ||
|
|
||
| In its current state, Confio’s implementation of the CosmWasm VM excludes library components and consists of a single implementation targeting the Cosmos SDK. | ||
| Our team is building a library implementation of CosmWasm that can be utilized by different host implementations to minimize the work to port Cosmwasm to different ecosystems. | ||
| Currently, the only implementation of CosmWasm consists of half of it written in Rust and half Golang. | ||
| Therefore, the current version was not compatible with Substrate and has never been leveraged outside of Cosmos. | ||
| This meant we had to build a VM from scratch. | ||
|
|
||
| Furthermore, we have two host implementations which allows developers to integrate CosmWasm in their ecosystems in a straightforward manner. | ||
| This ensures that our CosmWasm VM is highly portable with consistent execution semantics regardless of its host. | ||
| As a result, this would enable developers to integrate our CosmWasm VM as a pallet, within a frontend app, or inside a CLI tool. | ||
|
|
||
| The official CosmWasm VM uses Wasmd for the runtime. | ||
| It ensures that developers follow the same execution semantics, | ||
| thus, all CosmWasm contracts will function the same irrespective of the Cosmos blockchain they are executed on. | ||
| We utilized the Wasmd reference material to rewrite the Go portions of CosmWasm in Rust for implementation on our parachains. | ||

||
| ### Ecosystem Fit | ||
|
|
||
| CosmWasm would be able to facilitate the orchestration of cross-chain smart contracts between different parachains. | ||
|
|
||
| Our target audience consists of parachain builders, | ||
| and dApps in the Dotsama ecosystem that want to leverage a WASM based smart contracting framework. | ||
| We hope this VM enables and incentivizes developers to build in the Polkadot ecosystem as CosmWasm has been adopted by a large developer community. | ||
|
|
||
| We are the only team in the Substrate/Polkadot/Kusama ecosystem implementing CosmWasm for Substrate. | ||
