Qtum Joins Forces With Beam To Launch Atomic Swaps

The Qtum open-source blockchain platform has announced its partnership with Beam, a privacy coin based on the Mimblewimble protocol, in order to bring its users trustless atomic swaps.

Atomic Swaps are a secure mechanism of exchanging value between different blockchains, utilizing cryptographic security measures such as Hashed Timelock Contracts (HTLC) to avoid fraud when completing peer-to-peer cross-chain transactions. HTLC technology allows users to completely eliminate the need for third-party escrow, making the process completely trustless.

The new Atomic Swaps between Qtum and Beam is currently in testing, with no mainnet release scheduled as of publication. Users are now able to exchange tokens through atomic swaps in Qtum’s testnet environment using a CLI (Command Line Interface) wallet.

For Qtum, Beam represents the second Atomic Swap implementation after Bitcoin, with Qtum CIO Miguel Palencia citing admiration for Beam from the community as the reason for its inclusion:


“As a public blockchain focused on technical innovation, Qtum has a reputation for promoting the development and application of blockchain technology that guarantees security and scalability. We saw great success with our Bitcoin atomic swap integration back in January and want to continue to expand next-level interoperability with another cryptocurrency that the Qtum community admires: Beam.”Qtum CIO Miguel Palencia

Beam CEO Alexander Zaidelson likewise welcomed the implementation of Atomic Swap technology.

The original promise of cryptocurrencies is to allow users full sovereignty of their money without the need for any intermediaries. Atomic swap technology allows just that. Thanks to our strong cooperation with Qtum, we provide our users with a way to seamlessly swap Qtum to Beam without involving any third party, removing the custodial risk. Beam CEO Alexander Zaidelson

The Beam privacy coin is based on the Mimblewimble protocol, which makes transactions private by default. Nodes do not need to store the entire blockchain for transaction validation, making the protocol more scalable than existing privacy coins.

However, as noted in the available documentation, Atomic Swaps with Qtum are not covered under the privacy umbrella normally granted by Beam’s architecture.

Qtum itself is not a privacy protocol, specializing instead on offering a UTXO-based blockchain platform with multiple virtual machines, including EVM and the upcoming x86 VM. It also introduces an innovative Decentralized Governance Protocol (DGP) allowing specific blockchain settings to be modified by making use of smart contracts.
