The development of a new high-performance blockchain, dubbed Zero, backed by partners including Citadel, DTCC and Google Cloud, signals a growing effort to reconcile the demands of institutional finance with the foundational principles of decentralized ledger technology. The initiative, announced in February by LayerZero Labs, aims to provide infrastructure capable of handling institutional-scale transaction throughput while preserving the characteristics of a public blockchain.
The push for interoperability between blockchains, a long-standing challenge in the cryptocurrency sector, is now colliding with increasing institutional demand for efficient on-chain settlement, according to industry observers. Since the emergence of Litecoin in 2011, the ability for different blockchains to communicate, transact, and share data securely has remained a persistent technical hurdle and a significant source of risk.
Bryan Pellegrino, co-founder and CEO of LayerZero Labs, described his firm’s role as providing a “messaging layer” for data and value transfer across chains, akin to a packet on the internet. “It’s just arbitrary bytes, and anybody can use them,” he said. The Zero network is intended to function as global market infrastructure, capable of handling institutional workloads while maintaining a “neutral public permissionless layer.”
A central challenge lies in overcoming the trade-off between decentralization, and performance. Pellegrino explained that current blockchain designs typically force a choice: high decentralization with limited transaction speeds (around 15 transactions per second), or high performance at the expense of decentralization. The Zero network seeks to address this by offering both.
This emerging architecture increasingly resembles the internet’s layered structure, with a neutral base layer supporting regulated activity at the asset and application layers. Pellegrino drew a parallel to TCP/IP, advocating for a base layer that is “as neutral as humanly possible,” allowing applications and assets to define their own rules on top.
But, establishing trust in a permissionless environment remains a key obstacle. “Building the trust layer in a permissionless environment… It’s the chicken and egg,” said Karen Webster, CEO of PYMNTS, during a recent podcast discussion. In decentralized systems, trust is intended to be embedded in code, but cross-chain environments introduce new vulnerabilities due to varying trust assumptions across numerous networks.
Pellegrino noted that asset issuers connecting to a large number of chains face the challenge of navigating different sets of trust assumptions. LayerZero’s approach involves pre-execution verification, including simulating cross-chain state changes to ensure core invariants, such as solvency, are preserved before transactions are finalized.
Ryan Rugg, Citi Global Head of Digital Assets for Treasury and Trade Solutions, emphasized that institutions will not abandon established risk management frameworks. “Safety, soundness, security are table stakes,” she said, adding that Citi aims to provide services on blockchain rails if clients choose to utilize them.
The concept of “rails” highlights a shift towards a layered model, similar to traditional financial networks, where open technical standards underpin tightly governed financial applications. Stablecoins, which operate on public blockchains but are issued by centralized entities with compliance obligations, illustrate this dynamic. The underlying rails may be permissionless, but the assets themselves are subject to control.
Pellegrino cautioned against overcorrection, warning that removing the underlying decentralized capabilities would negate the technology’s value. The challenge, he said, is to accommodate those principles within regulated market structures. The initiative from LayerZero Labs, and the involvement of established financial institutions like Citadel and DTCC, represent a concrete step toward that goal.
