Atleta​


Atleta API is available on Web3 API platform.

Atleta is a modular, multi-layer, EVM-compatible, smart contract platform with native cross-chain interoperability, dedicated to servicing the sports industry.

Key Features of Atleta Network:

  • Modular Multi-Layer Architecture: Atleta's design separates core blockchain functions into distinct layers — Execution, Interoperability, and Storage. This modularity allows for scalability and adaptability, enabling seamless upgrades without disrupting ongoing operations.
  • Execution Layer: An Ethereum Virtual Machine (EVM)-compatible smart contract layer that facilitates transactions and supports the development of decentralized applications.
  • Interoperability Layer: Enables cross-chain communication, allowing for the transfer of assets and messages between different blockchain networks, thereby fostering a connected and collaborative ecosystem.
  • Storage Layer: Provides a decentralized data storage solution for various types of information, including videos, text files, and images, ensuring secure and efficient data management.
  • Nominated Proof-of-Stake (NPoS) Consensus Mechanism: Atleta employs NPoS to enhance decentralization and security. This consensus model allows a wide range of participants to contribute to network validation and governance, promoting inclusivity and resilience.
  • High Performance and Scalability: The network is designed to handle substantial transaction volumes, achieving approximately 60–80 transactions per second with a block time of around 6 seconds. This performance is facilitated by its Substrate-based architecture, which enables modular scalability.
  • Instant Finality: Utilizing the GRANDPA (GHOST-based Recursive Ancestor Deriving Prefix Agreement) finality gadget, Atleta ensures immediate transaction finality per block, enhancing security and efficiency.
  • EVM Compatibility: Atleta supports EVM-compatible smart contracts, allowing developers to deploy existing Ethereum-based applications and leverage liquidity across other EVM networks seamlessly.

Avail​


Avail API is available on Web3 API platform.

Avail is a Web3 infrastructure layer that allows modular execution layers to scale and interoperate in a trust minimized way.

A foundational Data Availability (DA) layer, Nexus interoperability layer, and Fusion Security network layer come together to form the Unification Layer.

  • The DA layer is a highly optimized, low-level layer, specifically constructed for data availability. This is the deepest blockchain layer, with the minimal functionality required to build cross-ecosystem interoperability on top.
  • Nexus acts as a light but powerful proof aggregation and sequencer selection ZK rollup on top of Avail, allowing for cross-rollup and cross-ecosystem settlement.
  • Fusion Security enables a basket of tokens to pool their crypto-economic security to serve and secure the Avail network.

Avail's mission is to streamline the rollup experience, offering a unified, efficient platform for both users and developers from any ecosystem. This vertically integrated stack aims to dissolve the growing pains and user fragmentation experienced today, enabling Rollups to seamlessly access users and liquidity across the entire blockchain landscape.

The Turing Testnet is live and marks Avail's final and definitive pre-Mainnet testing environment, aimed at vetting Mainnet deployments, executing extensive stress tests, and assessing network topologies for scalability and resilience.

Avalanche​


tip

Available for Freemium and Premium users.

Avalanche API is available on Web3 API platform.

Avalanche is an open-source platform for launching decentralized applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem. Avalanche is the first decentralized smart contracts platform built for the scale of global finance, with near-instant transaction finality. Ethereum developers can quickly build on Avalanche as Solidity works out-of-the-box.

Avalanche is an ecosystem that features three built-in blockchains: Exchange Chain (X-Chain), Platform Chain (P-Chain), and Contract Chain (C-Chain).

B2 Network​


B² Network API is available on Web3 API platform.

The B² Network is an advanced Layer-2 solution designed to enhance transaction speed, reduce costs, and broaden application diversity without compromising security. It is notable for being the first zero-knowledge proof verification commitment rollup on Bitcoin.

Key Features:

  • Zero-Knowledge Proof Verification: Utilizes zero-knowledge proof technology to ensure transactional privacy and security, allowing for the verification of transactions without revealing the underlying data.

  • Rollup Technology: Processes multiple off-chain transactions and rolls them into a single on-chain transaction, significantly increasing efficiency and reducing costs.

  • Turing-Complete Smart Contracts: Supports Turing-complete smart contracts, enabling complex computations and a wide range of decentralized applications (dApps) to run off-chain with enhanced performance.

  • Gate Commitment and Challenge-Response Mechanism: Integrates gate commitment and challenge-response mechanisms, leveraging Taproot on Bitcoin to ensure secure and private transaction confirmations.

  • EVM-Compatibility: The B² Network is compatible with the Ethereum Virtual Machine (EVM), allowing it to run Ethereum-based smart contracts and dApps. This compatibility enables developers to use existing Ethereum tools, libraries, and standards while benefiting from the B² Network's enhanced features.
