Composable is Building on Polkadot to Facilitate Cross-Chain Interoperability at All Levels

A critical component of Composable’s interoperability infrastructure will be built along a parachain — initially on Kusama, then on the Polkadot Network. Composable aims to leverage a Polkadot parachain to architect a solution capable of running all smart contract languages together and in communication with each other along one parachain.

This enables the full cross-chain interoperability of DeFi protocols at all levels, without the need for bridges. As a result, DeFi becomes far more functional, flexible, and streamlined.

Why Polkadot?

Composable Finance is opting to build its cross-chain interoperable solution on Polkadot (and along its canary network, Kusama) largely due to its parachain offering. Polkadot parachains are a series of small, application-specific chains connecting to Polkadot’s central governance chain, the relay chain. Validators act to validate the parachains, and collators act to maintain the parachains by hosting full nodes and parachain information as well as producing new block candidates to send to validators.

These parachains, which are procured via auction, involve an incredible degree of flexibility, making this an optimal place for Composable to build its cross-chain interoperable infrastructure. Importantly, parachains can have their own native economies and their own native tokens. Polkadot parachains also allow for customization of transaction fees, collator incentives, and validation processes. This allows us to create the ideal infrastructure needed to implement full interoperability between different blockchains and the protocols that make use of them.

What is Composable building on Polkadot?

We are working to build an assembly polyglot machine on top of a parachain. This solution will merge various existing infrastructures in the space like the Ethereum Virtual Machine (EVM), Tezos, ink!, and Solana’s eBPF, in order to run any sort of compiled smart contract in the same place and allow them to talk to each other on the same chain.

In addition to merging the functionalities of these existing infrastructures so all are compatible and can communicate with each other, we also aim to add advanced security features to the underlying state machine. This involves emulating the diamond standard on EVM and incorporating native access control list (ACL) checks via unforgeable references. Access control will also be an important security feature considered in Composable, via the implementation of native access control list (ACL) checks. ACLs determine which users are authorized to access which information.

What are the benefits and applications?

The end result of this Composable infrastructure is the ability to run all sorts of compiled smart contracts together, allowing them to seamlessly communicate with each other. This allows for smart contracts to communicate and collaborate at all levels, without the need for bridging as Polkadot presently requires, and with better underlying code safety and security features.

Not only will this break down the barriers between existing chains, but it will also support the creation of multichain applications, which leverage more than one blockchain basis to deliver new and improved functionality to users:

Further, building on a Polkadot parachain allows the Composable Ecosystem to become a part of the broader Polkadot ecosystem.

As a whole, by leveraging Polkadot, Composable is positioned to resolve the disparity between different blockchains, and the resulting liquidity fragmentation, inconvenience, inefficiency, and inflexibility.
