Harmony implements deep sharding with innovations on both protocol and networking layers of blockchain by introducing:
Harmony is a fast and secure blockchain with key innovations in state sharding and peer-to-peer networking. Its sharding uses secure proof-of-stake and decentralized randomness, and its networking achieves optimal cross-shard routing and fast block propagation.

Harmony's open, decentralized network is enabled through the use of the native protocol token - Harmony ONE. The token incentivizes and rewards a variety of participants including developers, validators/stakers, investors, and community members who develop, secure and govern the network. In order to use the network, users pay a small transaction fee denominated in the native Harmony token.
As of May 2019, Harmony has used approximately 37% of TGE funds according to the allocations below:
The following chart represents the number and breakdown of all ONE tokens that are intended to be released into circulation on a monthly basis.
Team tokens are locked until 2020 with 4 years vesting.
Harmony's scalable, high-throughput protocol is powered by a native token which is used for various forms of payment and participation in the protocol (staking, transaction fees, voting & governance).
Harmony uses blockchain to align incentives of different stakeholders, developers and businesses while allowing them to build open marketplaces of fungible and non-fungible tokens and assets. Furthermore, the upcoming application of zero-knowledge proofs will allow Harmony to become a data sharing platform that can overcome the conflicting problem plaguing many information and data markets: that individual market participants' have mutual distrust to share data but strong desire to acquire data themselves.
The Harmony token will function in the following aspects of the protocol:

Commercial Partnership and Business Development Progress
Harmony has a robust ecosystem building strategy focused on creating partnerships that drive adoption of the protocol across a variety of core use cases and verticals including gaming, data sharing, open marketplaces, provenance and supply chain tracking. At scale, Harmony helps businesses tokenize their assets and incentivize user engagement.
Notable key partners include Animoca (parent company of game assets like Garfield), Contentos (a content platform with 60M monthly users), and Timeless (a calendar-based service marketplace).
ONE token is not actively traded as of publish date of this report - the token will be available through the Binance Launchpad portal.
Harmony has in total 18 public repos; The main repo is the core protocol repo. The project in total has 2980 commits, 120 stars, 17 contributors, and 24 forks.

In Q3 2018, the Harmony team deployed a network of 40,000 AWS/GCP/Azure instances (nodes) in 100 separate shards (400 nodes each). The peak performance of the overall network was recorded at a rate of 118,000 TPS. The test block size was roughly 2 megabytes, and the average test transaction size was around 250 bytes.
In December 2018, the Harmony team achieved a block sync time of 1.36 seconds by implementing an adaptive IDA protocol.
The team then subsequently released several Testnet versions with the latest Testnet 3.0 in April 2019. The testnet 3.0 has been running reliably for over one month since launch, generating 220k+ blocks
The Harmony wallet, explorer and testnet documentation here.
A block explorer of Harmony's multi-sharded network is also available here.
The team recently launched the Harmony Lottery (to demonstrate its decentralized randomness) with hundreds of users on the first day. Harmony will also be launching Harmony Puzzle on Contentos platform to engage 50k+ users.
Each level of Harmony Puzzle is recorded on the Harmony testnet explorer and can be viewed during or after the game play.
The player should first play the game until the end (either ending at "Game Over" or winning all of the levels) and then click on the Harmony logo to be directed to the explorer for that specific game.
A player's move is shown in the "Sequence" line below. In this example, the player's moves were "UURDDLU" or "up-up-right-down-down-left-up".
Since early 2017, the Harmony founding team has been hosting a weekly4-hour gathering of entrepreneurs in the Bay Area to organically grow their team and community of partners.
The Harmony team has focused on a hybrid online/offline strategy to engage its community. The offline and online presences are split between three key strategies: content, channel, & ecosystem.

Official Harmony Forum
Harmony has been open source since January 2019 and has over 2,700 commits with over 100 stars from the community. Its team actively engages in technical discussions online on the Harmony Discourse forum at talk.harmony.one and on Discord. In Q1 2019, Harmony also announced a $1M USD worth of Harmony tokens technical bounty on Gitcoin to build out a full suite of developer tools with the goal of being the most accessible platform for developers to build on.
