ROADMAP & UPDATES
PRODUCT & METRICS
A high-throughput, low-latency and low-fee consensus platform
|KEY METRICS [as of 15 May 2019]|
|Initial Circ. Supply||3,061,800,000 ONE (24.3%)|
|Total Supply||12,600,000,000 ONE|
- 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.
- Built by a 12-person team featuring 7 engineers from Google, Apple, & Amazon and 2 PhDs
- Harmony helps businesses build marketplaces of fungible tokens for industry use cases such as energy credits and non-fungible assets (game collectibles, real estate). Harmony applies zero-knowledge proofs for data sharing (ad exchanges, credit ratings) while preserving the consumer’s privacy.
KEY FEATURES & HIGHLIGHTS
Harmony implements deep sharding with innovations on both protocol and networking layers of blockchain by introducing:
- Highly scalable FBFT (Fast Byzantine Fault Tolerant) consensus using BLS (Boneh-Lynn-Shacham) multi-signatures.
- Secure distributed randomness generation protocol using VDF (Verifiable Delay Function).
- Sharding with adaptive Proof-of-Stake for strong network security.
- Kademlia routing and erasure encoding for optimal network performance.

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 helps businesses build marketplaces of fungible tokens (such as energy credits and loyalty points) and non-fungible assets (such as game collectibles and real estate).
- Harmony is applying zero-knowledge proofs for data sharing while preserving the consumer’s privacy. Common industry use cases include ad exchanges, credit ratings and many other data consortia that would otherwise take many years to form among competing companies.

Harmony Token Ecosystem
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.
Token Governance & Use of Funds
As of May 2019, Harmony has used approximately 37% of TGE funds according to the allocations below:
- 65% Core Team & Protocol Development
- 15% Marketing & Community
- 15% Professional Services
- 5% Administrative & Office
ONE Token Release Schedule
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.
Token Overview & Use Cases
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:
- The token is used for staking, which is necessary to participate in the POS consensus & earn block rewards and transaction fees.
- The token is used to pay for transaction fees, gas and storage fees.
- The token is used in voting for on-chain governance of the protocol.

PRODUCT & METRICS
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.
Demo App / Product Launch
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 weekly 4-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.

Harmony Points of Differentiation
- Key innovations in state sharding (secure staking & resharding with decentralized randomness) and in peer-to-peer networking (optimal cross-shard routing, fast block propagation).
- Harmony is a POS-based state-sharding protocol, while existing protocol projects are mostly POW-based.
- Harmony's consensus is a fast BFT algorithm which uses BLS multi-sig and scales linearly with the number of nodes, while many existing projects uses the old single chain-based consensus (same as Bitcoin).
- Harmony's consensus doesn't have forks and has instant finality, while existing chains have forks and no instant finality.
- Harmony's cross-shard communication is sublinearly efficient due to the use of Kademlia routing and Erasure Encoding.
