Citrea is a Layer 2 ZK-rollup built specifically for Bitcoin, enabling scalability, lower fees, and Ethereum-style smart contracts without altering Bitcoin’s core protocol. By using zero-knowledge proofs and zkEVM compatibility, Citrea allows developers to build decentralized applications on Bitcoin using familiar Ethereum tools, while letting users transact with cBTC—its wrapped BTC token—more efficiently.

Metis is a Layer 2 scaling solution for Ethereum that uses Optimistic Rollups to dramatically reduce gas fees and transaction times while preserving Ethereum’s security. What sets Metis apart is its focus on enabling Decentralized Autonomous Companies (DACs)—business-friendly, plug-and-play blockchain entities with built-in tools for governance, reputation, and contributor management.

Somnia is a next-generation, EVM-compatible Layer 1 blockchain built to support high-performance, data-heavy applications like gaming, social networks, and metaverse interactions — all directly on-chain. With over 1 million transactions per second and sub-second finality, Somnia uses a novel MultiStream consensus protocol to process multiple transaction streams in parallel. This allows for real-time performance without sacrificing decentralization or Ethereum compatibility, opening up new use cases previously impossible on traditional chains like Ethereum and Bitcoin.

MANTRA is a layer-1 blockchain built to bridge traditional finance and DeFi by making regulatory compliance a core feature rather than an afterthought. Unlike many crypto platforms that skirt around legal frameworks, MANTRA embraces them — offering tools for digital identity verification, real-world asset (RWA) tokenization, and jurisdiction-specific compliance modules. Its OM token powers the ecosystem through governance, staking, and transaction fees, while the network’s liquid staking and identity solutions help make decentralized finance accessible to both users and institutions in a compliant way.

Flare Network is a layer-1 blockchain designed to solve one of crypto’s biggest challenges: interoperability. It enables different blockchains—especially those that don’t support smart contracts like Bitcoin, XRP, and Dogecoin—to interact and transact securely. Using its innovative State Connector, Flare brings off-chain and cross-chain data onto the blockchain in a decentralized, verifiable way. Combined with its Flare Time Series Oracle (FTSO) for decentralized price feeds, the network provides essential infrastructure for cross-chain DeFi, NFT interoperability, and dApps that rely on real-time, multi-chain data.

Tendermint is a foundational blockchain technology that enables fast, secure, and energy-efficient consensus for decentralized networks. It’s not a cryptocurrency itself, but rather the engine behind major blockchains like Cosmos, Binance Chain, and Crypto.com Chain. At its core, Tendermint separates the consensus layer (Tendermint Core) from the application layer (via ABCI), allowing developers to build blockchain apps in any programming language without needing to manage complex consensus mechanisms. It uses Byzantine Fault Tolerant (BFT) consensus combined with Proof of Stake, enabling instant finality — meaning once a transaction is confirmed, it can’t be reversed.

Walrus is a decentralized storage protocol built on the Sui blockchain that securely stores large files across a distributed network using erasure coding and blob storage architecture. Powered by the WAL token, it offers cost-effective, censorship-resistant storage with staking, governance, and reward mechanisms — making it an ideal solution for dApps, creators, enterprises, and privacy-conscious users seeking alternatives to centralized cloud storage.

Tokenomics analysis is the study of how a crypto token is structured, distributed, and used — acting as the economic backbone of any blockchain project. By understanding key elements like supply mechanics, utility, governance, inflation models, and vesting schedules, investors can better assess a token’s sustainability, risks, and long-term value, helping them avoid red flags and make smarter, data-informed investment decisions.
