Chorus One to Bridge Polkadot and Cosmos Ecosystems

The building of trust-less bridges between Polkadot and other blockchain networks is one of the top priorities for the Web3 Foundation. Chorus One’s effort lays the groundwork to build this technology for the Cosmos ecosystem. Additionally, the Interlay team has done excellent work on designing a Bitcoin bridge and we soon hope to turn this design into a full production implementation. Though we haven’t yet announced our bridging efforts related to the Ethereum ecosystem, there are a number of exciting initiatives related to this that are in progress which we hope to announce shortly. Some of these initiatives even have the potential to lead to bridges with many other leading blockchain networks.

SDK Blockchains from The Chorus One

Chorus One has received a grant by the Web3 Foundation to develop parts of a bridge that will enable Substrate and Cosmos SDK-based blockchains to interoperate as part of the fifth grant cohort.

SDK stands for Hyperledger Fabric Client software development kit. The interoperability provided by SDK blockchains will allow, for example, a user on a Cosmos SDK blockchain to move TerraUSD coins to Substrate chains to take advantage of applications in the Polkadot ecosystem.

Connecting Two Vibrant Ecosystems

are part of Chorus One's vision to provide the  ability to freely transfer value and information across sovereign blockchain networks and applications. The Polkadot and Cosmos ecosystems have both been at the forefront of cross-chain interoperability.

We are excited that Chorus One will contribute to bridging these two ecosystems with this initial project that will enable Cosmos SDK blockchains to keep track of consensus updates on Substrate-based networks.

“Polkadot combines the versatility of heterogeneous blockchains with the security and convenience of a single security pool and validator set. This is one of the most daring and promising visions of the blockchain space and could unleash unparalleled innovation. The Polkadot ecosystem is consistently shipping great software to advance that vision. We are incredibly excited to help bridge the flourishing Polkadot and Cosmos communities.” – Brian Fabian Crain, CEO of Chorus One
“A Substrate light client that's compatible with the Cosmos SDK is a great first step towards bridging the Polkadot and Cosmos ecosystems. We’re excited to see the results of this work and eventually a complete bridge between both networks." – Dieter Fishbein, Head of Ecosystem Development at Web3 Foundation

Update, October 15, 2020 – Chorus One began exploring how to make PolkaBTC available to the Cosmos SDK ecosystem via a Cosmos-Substrate IBC bridge.

Decentralization

Empowering Decentralization: Polkadot DAO Allocates 3M DOT for DeFi Growth

With an overwhelming majority of voters in favor, the Polkadot community has chosen to allocate 3 million DOT to enhance the ecosystem’s decentralized finance (DeFi) landscape. Made through three separate proposals via Polkadot’s decentralized governance (OpenGov), this decision provides an accessible, deep layer of native liquidity to help the ecosystem flourish. It also demonstrates the power of community-driven initiatives to shape the future of decentralized finance.Hydration (formerly known

Real World Assets

Polkadot and the Future of Real World Asset Tokenization

The world of blockchain is rapidly evolving, and one of the most exciting developments is the emergence of Real World Assets (RWA) tokenization.  What are Real World Assets? RWAs represent a wide range of physical assets, such as real estate, precious metals, artwork, intellectual property, and commodities. By tokenizing these assets on the blockchain, we unlock new possibilities for liquidity, transparency, and accessibility in traditionally illiquid markets. Unleashing the Potential of RW
