Avail, a modular blockchain aimed at unifying Web3 and optimizing data availability for scalable applications, has partnered with dWallet Network to introduce programmable native Bitcoin in rollups in the Avail ecosystem.
Polygon co-founder Anurag Arjun spun off Avail from Polygon into a separate entity in 2023. Avail was initiated within Polygon Labs at the end of 2020 and publicly introduced in mid-2021. It has plans to launch its mainnet later in 2024.
Leveraging dWallet’s decentralized multiparty computation (MPC) infrastructure, smart contracts using rollups built on Avail DA can natively manage BTC while programmatically preserving user ownership. This approach marks a shift from many Bitcoin L2 solutions that often rely on stealthy and risky cross-chain solutions, such as bridges, that require users to sacrifice ownership of their BTC.
According to the company, the collaboration aims to leverage dWallet’s MPC infrastructure to enhance Bitcoin’s capabilities by enabling the creation of native Bitcoin rollups, enabling more efficient and secure transactions and operations on the Bitcoin blockchain while supporting a broader range of functionalities that go beyond simple transactions.
The integration with the dWallet network powered by Avail Nexus, a zero-knowledge coordination package that integrates validity-based light clients and execution-proof aggregation, will also enable developers to strengthen Avail Fusion’s borrowed security with native assets from mature ecosystems, including BTC. and ETH.
Additionally, the dWallet Network integration will facilitate the Fusion Security model when it goes live, allowing users to safely store their BTC, ETH, or other assets in dWallets and leverage them to increase the security of the Avail ecosystem while maintaining the retain ownership of their own assets. . This introduces the first native multi-chain staking/restaking solution aimed at securing the consensus of another blockchain.
To implement the dWallet primitive, the dWallet network uses 2PC-MPC, a multi-party protocol invented by his team. This protocol enables the generation of an ECDSA signature in a non-covert manner, requiring participation from both the end user and a significant number of nodes.
dWallet technology enables a Solidity smart contract on an Avail rollup to create Bitcoin signatures and allows developers to manage a dWallet. Meanwhile, the dWallet Network approves the Avail rollup smart contract for logic enforcement, requiring users to complete the signature to prevent collusion and asset theft.
This latest integration aligns with Avail’s goal to unify Web3, using a comprehensive full-stack architecture consisting of three solutions: DA, Nexus and Fusion Security. Avail DA serves as the foundational layer for a diverse ecosystem of rollups, while Avail Nexus uses Avail DA as a trust anchor for ecosystem-wide coordination. Finally, Fusion Security will provide additional protection to a growing network of rollups and blockchains, strengthening Avail’s consensus mechanism.
Omer Sadika, co-founder and CEO of dWallet Network, commented:
“We believe the future of Web3 is multi-chain, not cross-chain, and together with Avail we will continue to work tirelessly to make this vision a reality.”
Strengthening the Avail ecosystem with dWallets accelerates the unification of Web3, addresses fragmentation issues and paves the way for a fully integrated, secure and native experience across all Web3 ecosystems, the companies said.
