Gram (GRAM) is a decentralized layer-1 blockchain developed in 2018 by the encrypted messaging platform Telegram. The project was then abandoned, taken over by the TON Foundation, and renamed from "Telegram Open Network" to "The Open Network". The Telegram team brought TON to the state of an almost full-fledged product. However, in 2020, Telegram CEO, Pavel Durov, left the project, and the development was handed over to independent crypto enthusiasts.

Hamster Kombat is a viral Telegram mini-app game that amassed a 300-million player base. It introduced and popularized a tap-to-earn mechanic. To reward the players, the Hamster Foundation has planned an airdrop which at the time can be considered the largest in the industry history.

Hedera Hashgraph is a blockchain network that allows the development of decentralized applications. Dr Leemon Baird and Mance Harmon are the founders of Hedera Hashgraph. The platform claims to be sustainable and energy-efficient, thanks to the Proof-of-Stake (PoS) consensus algorithm. HBAR is the native cryptocurrency of the Hedera network. It secures the network and is used to pay the transaction fees for applications on the chain. Users can also stake HBAR to earn passive income.

HIGH Token (Highstreet) is a native token of a decentralized commerce-centric play-to-earn metaverse built with virtual reality (VR) support. Apart from realizing a two-way currency flow within physical and virtual worlds, Highstreet (HIGH) introduces a market where in-game items can be redeemed for real-life products. During gameplay, users have an opportunity to explore the metaverse, fight monsters, and complete quests all the while acquiring goods that have both digital and real-world utility.

Humanity (H) is the native utility and governance token of the Humanity Protocol, a decentralized identity network bridging Web3 and biometrics. It utilizes unique palm-print recognition and zero-knowledge proofs to establish human uniqueness on-chain. The token acts as network gas, powers multi-pool staking rewards, and incentivizes zkProofer verification nodes.

GRASS is a decentralized network that allows users to earn tokens by sharing their unused internet bandwidth. This bandwidth is then used to train AI models and power web services, creating a novel way to monetize idle resources and democratize access to essential data for AI development.

Harmony is an open-source blockchain that uses a technique called state sharding, which separates a chain into segments that process transactions and store data in parallel, to support fast transactions. The protocol's Effective Proof-of-Stake (EPoS) staking mechanism allows token owners to delegate their holdings to network validators but aims to reduce the centralization of delegated assets. Harmony has a native token, ONE, that owners can use to stake on the network in exchange for block rewards and pay for transactions.

Helium (HNT) is the native token of the Helium Network, a decentralized wireless infrastructure (DePIN) powered by global hotspots. After migrating to Solana, the ecosystem transitioned to a single-governance model using HNT. In 2026, the project focuses on 5G expansion, IoT adoption, and a deflationary burn-and-mint mechanism driven by network usage.

Horizen (formerly ZenCash) is a privacy-focused cryptocurrency that aims to provide secure and anonymous transactions. It utilizes a decentralized network of nodes to maintain privacy and security. Horizen also offers a platform for building dApps, enabling developers to create their own privacy-focused applications on the blockchain.

A key feature of HyperCash (HC), previously known as Hcash, is optional privacy: white addresses are public, black addresses are protected by zero-hash proofs. HC combines DAG and blockchain, secured by PoS and PoW respectively.
