The network is operational with supporting infrastructure including a block explorer, node map, and desktop client software for macOS, Windows, and Linux platforms.

Pearl Research Labs is building an L1 blockchain protocol that uses Proof-of-Useful-Work (PoUW), replacing traditional hash-based mining with GPU matrix multiplication (MatMul) as the native consensus mechanism. The core technical differentiator is a custom MatMul implementation that lets GPUs produce blockchain proof-of-work as a side-effect of AI training and inference workloads, enabling a single computation to serve both purposes simultaneously. The network targets GPU operators, AI compute buyers, and blockchain participants seeking an alternative to energy-wasteful mining, with a compute marketplace and block explorer already deployed. Pearl publishes a formal whitepaper, a cryptographic research paper, and open-source code, and has partnered with AI inference provider Together AI to validate the compute layer. The network's native token ticker is PRL.

Peercoin (ticker: PPC) is a proof-of-stake blockchain that launched in 2012, making it one of the earliest cryptocurrencies and the originator of the proof-of-stake consensus mechanism as an alternative to Bitcoin's proof-of-work. The protocol combines proof-of-stake for security with an optional proof-of-work mining layer, and is designed around a low-inflation economic model intended for long-term sustainability. Peercoin is governed and supported by the Peercoin Foundation, a non-profit entity that coordinates development, documentation, and community resources. The project targets users and developers seeking an energy-efficient, decentralized base-layer blockchain, and the coin is tradeable on third-party exchanges with a wrapped version available for use in other ecosystems.

Unlike general-purpose blockchains, it embeds compliance requirements such as identity verification, asset issuance rules, and confidentiality features directly into the protocol layer. The network is governed by the Polymesh Association, a Switzerland-based nonprofit, and uses POLYX as its native utility token for staking, governance, and transaction fees. It targets institutional issuers, asset managers, and regulated financial entities seeking to tokenize securities and other real-world assets on-chain with built-in regulatory controls.

PopChain is a blockchain network designed for decentralized content distribution, enabling direct transactions between creators and consumers without intermediaries. The network uses a hybrid consensus mechanism combining Proof-of-Work and Proof-of-Service to address performance limitations of traditional Proof-of-Work systems. Scalability is achieved through side chains that connect to the main chain via smart contracts. The POPBOX is a hardware device that allows network participants to contribute idle storage and bandwidth resources in exchange for PopChain Cash, the network's native token, through a mining process. The project maintains a partnership with Vital Block related to the ConnectFi blockchain, indicating potential cross-chain integration capabilities.

Shielded Technologies collaborates with the Midnight Foundation, which oversees the Midnight protocol ecosystem governance and development.

Signet is an Ethereum rollup developed by init4 Technology that facilitates cross-chain settlement within a single Ethereum block. The system eliminates withdrawal delays by employing market-based asset swaps between chains, conditional transactions that execute or revert atomically, and round-robin block production to avoid auction dynamics. Rather than relying on proving systems or state roots, settlement occurs through these swap mechanisms. The platform supports DeFi users, application developers, and solvers requiring instant liquidity, real-time composability with Layer 1 events, and atomic cross-chain execution without partial fills. Solidity contracts deploy without modification, and standard development toolchains including Foundry, ethers.js, and viem are compatible without additional configuration.
