DoubleZero is a decentralized network designed to enhance the connection and data sharing between blockchains and distributed systems.
The platform uses dedicated fiber-optic links and hardware contributed by individuals and organizations, turning unused infrastructure into a high-performance global network.
Contributors set up DoubleZero Devices (DZDs) and run the DoubleZero software to provide services like routing, filtration, and data processing.
2Z is the network’s native token. It’s used to reward contributors, pay for bandwidth and optimized routing, and participate in governance.
What Is DoubleZero?
DoubleZero is a decentralized connectivity network designed to enhance the communication between blockchains and distributed systems. The platform consists of connections contributed by participants worldwide to create a stable and scalable communication layer.
To join the network, contributors deploy DoubleZero Devices (DZDs) in data centers. These devices manage routing, traffic flow, and data processing, and are linked through DoubleZero Exchanges (DZXs) located in major hubs. Together, they form a global mesh of high-performance links designed to support reliable and consistent connectivity.
By contributing to the network, you can earn 2Z tokens when your connections improve speed and reliability. At the same time, blockchain validators and applications benefit from faster communication, fewer delays, and more dependable performance.
How DoubleZero Works
Bandwidth contributions
Contributors on the network provide dedicated fiber-optic bandwidth between two data centers. At each endpoint, they install DoubleZero Devices (DZDs), which are pieces of hardware that connect their link to the network.
These devices run DoubleZero’s software, which prepares the link for participation. Once the setup is confirmed through smart contracts, the connection is officially added to the DoubleZero network and becomes part of its global system.
Network integration
Individual links are connected together through DoubleZero Exchanges (DZXs). These exchanges serve as hubs in major cities, where the connections of different contributors converge and are woven into the broader network.
By joining through a DZX, each link becomes part of a continuous global network. The system’s controllers automatically configure the devices so data can move smoothly across different paths. This process allows DoubleZero to operate as a coordinated network rather than a set of isolated links.
Smart contracts
All contributions are managed through smart contracts, which act as automated agreements on the blockchain. These contracts handle tasks like verifying new connections, recording usage, and distributing rewards. Contributors are paid in 2Z tokens when their links improve the network’s overall performance. Additional participants, known as resource contributors, help keep the system running by monitoring activity and publishing data on link quality.
Key Features
Dedicated bandwidth
When you connect to DoubleZero, you use bandwidth from dedicated fiber-optic links instead of relying on the public internet. These links are committed and measured, which means your applications can operate on more predictable and consistent connections. For systems like blockchains, this helps reduce the uncertainty that often comes with internet-based routing.
Edge filtration
As data passes through DoubleZero, it is filtered at the edge of the network. DoubleZero Devices (DZDs) remove duplicate or unnecessary traffic before it reaches validator node operators or infrastructure providers. By reducing this overhead, they can allocate more resources to other functions, such as block validation, transaction processing, and infrastructure management.
Optimized routing
When you send messages through DoubleZero, they follow routes that are optimized for speed and reliability. This can reduce latency and jitter compared to the public internet. For you, this means that data reaches its destination more quickly and consistently, which is particularly valuable in distributed systems where timing plays a crucial role.
Incentive model
If you contribute bandwidth or computational resources, you can earn rewards in 2Z tokens. These rewards are tied to measurable improvements in performance, such as reducing latency or increasing throughput. This means you are compensated based on the quality of your contribution, while applications and infrastructure providers benefit from a stronger and more efficient network.
The 2Z Token
2Z is the native token of the DoubleZero protocol, issued on the Solana blockchain as an SPL token. It’s used within the ecosystem for many purposes, including:
Network access: Users can pay with 2Z to access DoubleZero’s dedicated connectivity services. In some cases, payments may be made in Solana’s native token, SOL, or other supported assets, which are then converted into 2Z.
Rewards: Providers can earn 2Z tokens for contributing computational power, security, and fiber optic infrastructure. Payouts are performance-based, with rewards given only when resources add value and exceed the baseline of the public internet.
Staking: 2Z holders will be able to stake or delegate their tokens to resource providers, reinforcing network security while earning rewards.
DoubleZero (2Z) on Binance HODLer Airdrops
On October 2, 2025, Binance announced 2Z as the 48th project on the Binance HODLer Airdrops. Users who subscribed their BNB to Simple Earn and/or On-Chain Yields products from September 26 to 28 were eligible to receive 2Z airdrops. A total of 35 million 2Z tokens were allocated to the program, accounting for 0.35% of the total token supply.
2Z was listed with the Seed Tag applied, allowing for trading against the USDT, USDC, BNB, FDUSD, and TRY pairs.
Closing Thoughts
DoubleZero is a decentralized network that focuses on enhancing the connection and data sharing between blockchains and distributed systems. The platform connects dedicated bandwidth, devices, and hubs into a network of optimized links that is designed to provide more predictable performance than typical internet routing. For contributors, the network provides a way to utilize idle capacity, while for applications, it offers more stable and efficient data transmission.

Caldera is a Rollup-as-a-Service (RaaS) platform that helps developers launch custom, app-specific rollups with just a few clicks.
The platform is built around two parts: the Rollup Engine (to create and manage rollups) and the Metalayer (to connect them for cross-chain communication).
Rollups launched with Caldera are automatically connected and can communicate, share liquidity, and transfer assets with each other easily.
Introduction
Building on Ethereum can be challenging when the network is busy. As more people use the network, transactions can take longer and cost more. Rollups help by moving activity off the main chain, but many still operate on their own like isolated islands, making it hard to move data or assets between different chains.
Caldera lets you launch your own rollup in minutes, designed specifically for your app and automatically connects it to other chains. That means faster transactions, lower costs, and a smoother experience for users and developers.
What Is Caldera?
Caldera is a Rollup-as-a-Service (RaaS) platform that lets developers launch rollups that are designed specifically for their app’s needs. Instead of starting from scratch, teams can use Caldera’s tools to quickly spin up fast, flexible rollups tailored for use cases like decentralized finance (DeFi), gaming, Non-Fungible Tokens (NFTs), or social platforms.
The Rollup Engine
At the heart of Caldera is the Rollup Engine, a powerful deployment system that lets developers launch and manage custom rollups in just a few clicks or Application Programming Interface (API) calls. This is similar to how Amazon Web Services (AWS) makes it easy to run web applications in the cloud, the Rollup Engine takes care of the heavy lifting so developers do not need to stress over the technical details or be blockchain experts to get started.
Metalayer
The Metalayer is the invisible network that links all Caldera rollups together, allowing them to communicate, share liquidity, and pass messages securely. Instead of each rollup being an isolated island, apps can interact with each other across chains, and users can move assets like tokens or NFTs seamlessly between them.
Together, the Rollup Engine and Metalayer let developers build flexible, application-specific chains without giving up the benefits of a shared ecosystem.
How Does Caldera Work?
1. Launch a rollup
Developers start by choosing their rollup settings using the Rollup Engine:
Execution layer: Choose from popular rollup frameworks such as Arbitrum Nitro and Optimism Bedrock for optimistic rollups or go with zero-knowledge (ZK) solutions like zkSync’s ZK Stack or Polygon CDK.
Data availability: Choose between options like Ethereum, Celestia, or Avail to store transaction data.
Customization: Adjust performance settings, roll out software upgrades, and scale computing resources on demand
2. Connect instantly with the Metalayer
Once deployed, your rollup is automatically plugged into the Metalayer, which enables:
Intent-based bridging: If you want to move stablecoins like USDC from one rollup to another, the system automatically finds the fastest and cheapest way to do it. This is powered by bridging partners like Across (a cross-chain bridge), Eco (a protocol for efficient transaction routing), and Hyperlane.
Fast settlement: With Hyperlane handling the messaging layer, transfers and cross-chain communication are completed in seconds.
Developer Tools: Caldera provides APIs, SDKs, and ready-to-use UI components for developers to build cross-chain apps without writing custom bridging logic.
3. Scale on demand
Caldera’s modular architecture lets developers:
Launch new rollups: A DeFi app could spin up a separate rollup just for high-volume traders, while a gaming platform might launch dedicated rollups for different game worlds or regions.
Upgrade without downtime: Developers can roll out protocol upgrades like adding new features or integrating with different data availability layers without disrupting the user experience.
Scaling compute resources: If demand increases, like during an NFT drop or a major in-game event, teams can increase computing power to maintain performance.
Ecosystem Overview
Caldera is powering an expanding network of over 50 active rollups across a wide range of use cases, including DeFi, gaming, social apps, and infrastructure protocols.
Some of the notable chains built on Caldera include:
Manta Pacific: A modular Layer 2 focused on ZK applications.
ApeChain: Designed for the ApeCoin ecosystem, enabling fast and cheap transactions for NFTs and gaming.
Injective’s inEVM: A rollup that brings EVM compatibility to the Injective ecosystem.
ERA Token
The ERA token is the native utility token of the Caldera ecosystem. The token is used for a variety of purposes, including:
Gas fees: ERA is used to pay for transaction fees across the Metalayer, supporting interactions between rollups.
Staking & Network Security: Validators stake ERA to help secure the network, verify cross-rollup messages, and support future subnets like those involved in generating ZK proofs.
Governance: ERA holders can propose and vote on protocol changes, grant funding, and elect members to roles such as the security council. While initial governance is bootstrapped by the Caldera Foundation, long-term decision-making will move to on-chain community voting.
Caldera (ERA) on Binance HODLer Airdrops
On July 16, 2025, Binance announced ERA as the 27th project on the Binance HODLer Airdrops. Users who subscribed their BNB to Simple Earn and/or On-Chain Yields products from July 1 to 5 were eligible to receive ERA airdrops. A total of 20 million ERA tokens were allocated to the program, accounting for 2% of the total token supply.
ERA was listed with the Seed Tag applied, allowing for trading against the USDT, USDC, BNB, FDUSD, and TRY pairs.
Closing Thoughts
Caldera offers a modular way to build and scale blockchain apps by letting teams launch custom rollups with built-in connectivity across chains. With the Rollup Engine handling deployment and the Metalayer supporting cross-chain communication, Caldera aims to make building on-chain apps faster, smoother, and more flexible.
