On October 10, delta, which aims to create a network with global state sharing, announced the completion of a $11 million financing round. This financing is divided into two phases, including a pre-seed round led by Figment Capital and Maven 11, and a seed round led by Variant and DBA. Other investors include Reverie, Castle Island Ventures, Credibly Neutral, Ambush Capital, Robot Ventures, Delphi Ventures, Public Works, Komorebi Collective, and others.
The delta network provides developers with a balanced solution for sovereignty and interoperability by separating execution and data availability. The system also introduces zero-knowledge proof settlement methods to achieve seamless multi-domain interoperability.
What is delta?
Delta is a network composed of autonomous execution environments connected by a decentralized, censorship-resistant base layer. Delta separates ① execution and ordering from ② data availability and settlement. Execution and ordering occur within domains (similar to rollups/execution sharding), while data availability and settlement are provided by a network of validators operating the base layer. The overall composition of these components forms a unified global state machine.
While the global state is shared, domains have complete control over their block space. They can be application-specific or general-purpose computing platforms; they can use any existing virtual machine or develop their own custom programs; the operational model can be decentralized, centralized, or even permissioned. Any application, business, or service provider can set up their own domain without permission. Their users can pay fees in any token through off-chain subscriptions or not pay any fees at all.
Users gain censorship resistance from the base layer. They decide how to use their assets and maintain the ability to self-custody—ensuring their funds are secure and they have the right to exit the domain without permission. Assets exist on the base layer, so there is no need for each domain to implement separately.
The base layer facilitates native interoperability between domains. For users, delta provides an instant, nearly free, bridge-less experience for transferring assets from one domain to another.
The key to achieving these features is zk settlement. Similar to rollups, domains can take various forms, but they all settle to the same base layer. Unlike rollups, they achieve settlement through direct integration of zero-knowledge proofs into the base layer. This "fixed" zk settlement approach elevates global interoperability between local networks to unprecedented levels. Domains can interact with each other, and even perform atomic interactions, without the need for global coordination like in blockchains.
Delta's state model implements a leaderless consensus protocol that outperforms any blockchain. The domains in delta essentially isolate the ability to change the global state based on spending. Due to this limitation, there is no need for full ordering of transactions on the base layer. Without ordering, domains can continuously stream their state changes using minimal Byzantine Reliable Broadcast (BRB) protocols. In addition to reducing the communication overhead per transaction, delta's leaderless, unordered consensus is more robust and scalable than the fully ordered consensus implemented by all blockchains to date. Unlike these systems, delta can linearly scale throughput simply by adding more machines.
Solving the biggest problems in cryptocurrency
Platforms and applications have as much optionality as Web2 and are as composable as smart contracts on the same blockchain. However, application chains and rollups require complex interoperability solutions to "glue" independent blockchains together. The drawbacks of this approach currently far outweigh the benefits of sovereignty.
For example, consider the challenges new chains face in onboarding users.
All on-chain applications should provide a seamless experience for new users to deposit assets like stablecoins. To achieve this experience, new chains face significant challenges in their choices:
- It is crucial to enable stablecoin issuers to deploy locally on-chain in terms of cost and process. This option is only available to projects with sufficient funds and resources.
- Requiring users to bridge from the Rollup's settlement layer is highly secure but poses a significant barrier for users who do not yet hold stablecoins on the Rollup's settlement layer.
- Application chains and Rollups can collaborate with third-party bridge providers, but this approach requires significant trade-offs. Relying on a single provider may pose unbearable security risks, while using multiple providers can lead to a poor user experience as users must consider multiple versions of the same underlying asset.
As an integrated system, delta addresses the most critical challenges associated with launching application chains or rollups:
Allocation
- On integrated chains, attracting users and liquidity is a shared goal between the chain and its applications. On application chains, builders can only rely on their own efforts—users and assets cannot be shared.
- On delta, assets and users are globally shared—once they are loaded onto delta, they can be accessed by all domains built on delta. At the same time, domains retain maximum control, owning and optimizing their user experience.
Interoperability
- Users want to interact with multiple applications simultaneously without friction. To facilitate this experience, application chains must reintroduce intermediary services (third-party infrastructure and liquidity providers) to abstract away a lot of complexity. Blockchains are designed to eliminate these intermediaries, and each layer of abstraction moves away from the original value proposition.
- On delta, since the state is globally shared, domains no longer need intermediaries to connect with other domains. Users can move from one domain to another without any friction caused by intermediaries or routing complexities.
Barriers to entry
- Building and maintaining an application chain or rollup requires more costs and resources compared to deploying a set of smart contracts on an integrated chain.
- On delta, domains can be lighter than other forms of application chains and rollups. Unlike rollups, domains do not have to prove complete execution paths and/or handle long withdrawal periods related to fraud proof dispute periods. Unlike independent application chains, domains do not need to bootstrap validator sets.
Returning to the previously mentioned challenge of stablecoin accessibility, this challenge does not exist for domain builders on delta. On delta, stablecoin issuers only need to deploy once, and all domains can equally access their holders and liquidity without sacrificing control and reasoning about interoperability complexity.
The vision of delta
Delta will broadly enhance the vision of application chains and horizontal scaling. But delta not only addresses the problems of existing methods but also creates a new design space.
Delta provides its users with two inalienable rights—self-custody and permissionless exit rights. With these guarantees, delta can safely reintroduce a range of trust models at the execution layer. For the first time, blockchains can offer permissioned services while still ensuring that user funds are completely secure and can be withdrawn at any time. This allows a new category of enterprises, games, and even government blockchains to coexist on public networks with trustless and decentralized blockchains, achieving unprecedented levels of interoperability between them.
