Goliath Mainnet Goes Live as Onyx Shifts to a Layer-1 Blockchain
Onyx Protocol launched the Goliath mainnet on Thursday, moving from a Layer-3 application chain to a sovereign Layer-1 blockchain built for banks and financial service providers. The release adds live XCN liquid staking, an Ethereum bridge, and token swap functionality inside the Onyx App.
This launch marks the latest step in a development cycle that started in 2024. A testnet followed in late 2025, and the mainnet had originally been planned for the first quarter of 2026.
Goliath Blockchain Performance and Network Design
Goliath uses asynchronous Byzantine Fault Tolerance to deliver instant transaction finality. Onyx says the network can handle up to 100,000 transactions per second.
That figure goes beyond the project's earlier goal of matching Visa's capacity of roughly 24,000 transactions per second.
What Goliath Offers for Banks and Financial Services
Goliath is built for institutional finance rather than general-purpose decentralized applications. Onyx has pointed to cross-border payments, supply chain verification, and healthcare audit systems as key use cases.
The protocol presents Goliath as infrastructure that gives banks access to DeFi liquidity while still offering the speed and reliability they expect from traditional financial networks.
Native XCN Utility on Goliath
XCN is the native token of the Onyx ecosystem. On Goliath, it now functions as the gas token while continuing to exist as an ERC-20 asset on Ethereum.
A native bridge lets users transfer XCN between Ethereum and Goliath. Within the Onyx App, users can also swap XCN, ETH, and USDC on the Goliath network.
Liquid Staking and Token Swaps in the Onyx App
Liquid staking is now live on Goliath. Rewards build automatically and are paid out at the time of unstaking in a single transaction.
The Onyx App also includes token swap functionality tied directly to the Goliath network, expanding how users can interact with XCN, ETH, and USDC.
Market Context Around the Goliath Launch
Even with the mainnet launch, XCN has still been affected by broader market pressure. The token has fallen in recent days during a wider crypto downturn, as Bitcoin dropped to around $66,000.
The rollout also comes as Onyx competes with established institutional blockchain infrastructure providers, including Ripple, Stellar, and JPMorgan's proprietary blockchain products.
Onyx Priorities and the Challenges Ahead
Onyx said its next priorities are expanding validator participation, growing the developer ecosystem, and scaling cross-chain capabilities.
The bigger question is whether Goliath can bring in real banking partners and support actual institutional transaction volume. One analysis framed it bluntly: until Goliath secures banking partners and processes real institutional volume, the market is treating it as a promise rather than a proven platform.
