• Syscoin has launched zero-knowledge proof-of-data availability into its ecosystem, merging Bitcoin’s mining mechanism with DeFi and leveraging Bitcoin’s infrastructure for blockchain innovation.
• The solution will allow the deployment of scalable solutions on Bitcoin without compromising its security or decentralization in a monumental step for Bitcoin adoption beyond speculation.

Syscoin has announced the world’s first zero-knowledge proof-of-data availability in a historic launch that ushers in a new era of developing and deploying scalable applications on the Bitcoin blockchain.

Syscoin, which has been pushing to leverage Bitcoin’s secure infrastructure for the deployment of dApps, partnered with NodeKit and Polyhedra Network on the initiative.

For years, developers have been working on the blockchain trilemma—the tradeoff between scalability, security and decentralization. Some, like Ethereum, chose scaling over decentralization by switching to proof-of-stake, but recent developments like a bug on the Nethermind client prove how risky this approach can be.

Syscoin solves this trilemma using the battle-tested proof-of-work consensus mechanism for maximum security. To solve scalability, the network is introducing zkDA, a fundamental shift in how blockchain networks approach scaling while still providing Bitcoin’s security to any rollup.

With zkDA, rollups can directly leverage Bitcoin through Syscoin’s merged mining, essentially functioning as Bitcoin rollups regardless of the network they are deployed on.

A unique aspect of zkDA is that it integrates with almost every other blockchain infrastructure. This makes it a versatile solution for a wide range of dApps as it integrates with different execution and data availability layers, ranging from simple transactions to complex smart contracts.

Syscoin developer Jagdeep Sidhu commented:

This collaboration brings scalable solutions without compromising security and decentralization, fundamental to blockchain development.

Security, Scalability and Flexibility: Syscoin Changes the Game with zkDA

Commenting on the partnership, Polyhedra CEO Abner Jia stated:

Our partnership leverages Bitcoin’s security with Syscoin’s zkDA, providing a path for Bitcoin to compete with other major smart contract platforms.

Syscoin’s revolutionary solution centres on the Proof of Data Availability (PoDA) service. This service delivers over 400 kb of data availability per second, operating on the Syscoin UTXO chain. It ensures that the blockchain handles vast amounts of data generated by all smart contracts on the network.

In addition to making data available, PoDA ensures that the data is verifiable and accurate, making Syscoin’s zkDA clients agile and responsive to evolving blockchain demands.

Some of the key aspects of the zkDA offering include the aforementioned Bitcoin integration. This is made possible through zkBridge, which facilitates two-way transactions between the Bitcoin blockchain and Rollux, Syscoin’s Ethereum Virtual Machine (EVM) Layer 2 network. This essentially creates a robust Bitcoin Layer 3 that draws the best of Bitcoin and Ethereum.

The zkDA clients get a receiver chain on Rollux, giving them unprecedented levels of interoperability and a sender chain that they can leverage to transfer Syscoin assets to other chains. Additionally, they get access to NodeKit’s leading rollup solutions.

Commenting on the partnership, NodeKit founder Noah Pravecek stated:

Our collaboration with Syscoin enhances our sequencing solutions, addressing decentralized and cross-chain rollup complexities.
