DigiByte is an open-source, decentralized UTXO blockchain created in late 2013 and launched in early 2014, operating with no central company or CEO and funded entirely by its volunteer community rather than an ICO or premine. The protocol uses five cryptographic mining algorithms alongside real-time difficulty adjustment via DigiShield, and the Odocrypt algorithm that rotates every 10 days to resist ASIC centralization. Blocks are produced every 15 seconds, making it roughly 40 times faster than Bitcoin, with SegWit enabling high transaction throughput at negligible fees. Beyond its native DGB currency, the platform supports DigiAssets for tokenizing real-world assets, smart contracts, decentralized applications, and Digi-ID for secure, blockchain-based authentication. It is a community-driven, globally distributed project with no identifiable legal headquarters.

Enya Labs is the core development contributor to Boba Network, an Ethereum Layer 2 scaling solution built on the Optimistic Rollup architecture. The company developed HybridCompute, a technology that bridges off-chain Web2 data sources with on-chain smart contracts and decentralized applications, enabling use cases across DeFi, NFT, GameFi, and SocialFi verticals. Boba Network's native token is BOBA, and the protocol targets developers building dApps that require real-world data connectivity alongside the throughput and cost benefits of an L2.

FAIR is a Layer 1 blockchain built around a consensus mechanism called Proof-of-Encryption, which uses the BITE (Blockchain Integrated Threshold Encryption) protocol to encrypt transactions before consensus and decrypt them only after finalization. This design is intended to eliminate MEV (Maximal Extractable Value) exploits such as front-running and sandwich attacks at the protocol level rather than as an application-layer patch. The chain runs a C++-based parallelized EVM with instant finality, maintaining Solidity tooling compatibility while adding native privacy features aimed at AI agents and institutional DeFi users. FAIR is also integrated with the SKALE ecosystem: SKALE Manager is planned to migrate from Ethereum to FAIR, SKL holders will receive a portion of FAIR's native token supply, and SKL burning is planned as a mechanism to run validator nodes on the network.

Fluent is an Ethereum Layer 2 blockchain implemented using zkRollup technology. It features a multi-virtual machine architecture that enables smart contracts written in EVM, SVM, and WebAssembly (Wasm) bytecode to execute on a single chain.

The ecosystem includes a block explorer (Fogoscan), a points/rewards program (Fogo Flames), and a suite of trading applications being built on the L1.

Fractal Bitcoin is a Bitcoin scaling network that extends the Bitcoin codebase to enable faster block times and greater throughput while preserving Bitcoin-native primitives such as UTXO accounting, Ordinals, and BRC-20 tokens. The protocol uses recursive Bitcoin instances rather than a separate virtual machine, allowing developers to deploy applications that inherit Bitcoin's security model without forking the base layer. It is backed by UniSat, the open-source Bitcoin Ordinals wallet provider, and its native token is FB. The ecosystem includes an AMM DEX called InSwap, a block explorer via Uniscan, UTXO-based farming, and a gaming platform called SatWorld, all built natively on the Fractal chain.

Gigachain is a Layer 1 blockchain protocol built around trustless parallel execution, a design intended to overcome the throughput limitations of sequential transaction processing common to most existing blockchains. The core technical differentiator is its approach to parallelizing transaction execution without sacrificing trustlessness, distinguishing it from other parallel execution attempts that rely on optimistic or centralized coordination. The project was incubated by the Telos Foundation and includes an incentive program for wallets that stake TLOS tokens, reflecting its roots in the Telos ecosystem. The team includes engineers and advisors with backgrounds at Polygon, Consensys, Avail, IOHK, and Telos, with expertise spanning zero-knowledge proofs, cryptography, DeFi, and interoperability.

Grin is an open-source, privacy-preserving cryptocurrency launched in January 2019, built on the MimbleWimble blockchain protocol. It features no visible amounts or addresses, trivial transaction aggregation, and a linear emission schedule of 1 GRIN per second, designed to produce a fair coin distribution without an ICO, pre-mine, or founder's reward. The protocol uses MimbleWimble's cryptographic properties to prune historical transaction data from the chain, keeping storage requirements manageable over time. Grin is GPU-minable and ASIC-resistant by design, targeting individual miners and privacy-conscious users seeking censorship-resistant digital cash. The project is maintained by a globally distributed group of volunteer developers and funded entirely through community donations, with no controlling company, foundation, or individual.
