1. Interlay awarded Web3 Foundation grant to create Bitcoin (BTC) – Polkadot (DOT) bridge

Interlay, a project to create transactability for DeFi platforms across blockchains, has announced its work on bringing Bitcoin to the Polkadot ecosystem. They will build a parachain on Polkadot that will associate with the Bitcoin (BTC) blockchain. Interlay is now executing a PoC for a BTC-Parachain in Substrate and Rust. The announcement is published via interlay medium post on March 05, 2020.


The new bridge  links the blockchain Polkadot network to Bitcoin (BTC). The parachain will use the open source XCLAIM framework and leverage collateralized intermediaries. Intermediaries are committed to prove correct transaction execution on Bitcoin, which ensures that users face no financial damage. This open-source R&D project, based on top-tier academic research, is funded by a Web3 Foundation grant.

Polkadot Uses Parachains to Link Other Networks

Polkadot was launched back in 2016 by Gavin Wood, the co-founder of Ethereum. They connect and launch blockchain-based apps by employing parachains to link various networks.As soon as the Polkadot BTC bridge is be done, users can access and utilize the parachainso as to create PolkaBTC on the 1:1 rule by using their deposited BTC.The original BTC will be redeemable at any time.


XCLAIM Design Principles

  1. Financially Secure
  2. Dynamic and Permissionless
  3. Fast and Efficient


Technical Specifications

The 200-page specification for the BTC-Parachain provides a top to bottom guide of how to execute XCLAIM between Bitcoin and a Polkadot parachain.The particular is part into two sections:


XCLAIM(BTC,DOT):This part implements protocols for the issue, transfer, and redemption of Bitcoin-backed tokens on Polkadot.

BTC-Relay-The BTC-Relay component is used to verify that certain transactions have happened on the Bitcoin blockchain. BTC-Relay tracks the Bitcoin main chain, parsing, verifying, and storing block headers and dealing with forks when essential.


The Interlay group stated:-


As a next step, we are developing BTC-Relay in Rust using the Substrate framework, followed by an implementation of XCLAIM(BTC,DOT). This work will be available as an open-source contribution once the first code iteration is stable. We are also actively seeking to integrate PolkaBTC into other parachains.
