Harmony ONE


HARMONY ONE

Harmony is an open and fast blockchain. Our mainnet runs Ethereum applications
with 2-second transaction finality and 100 times lower fees.
Harmony’s mission is to scale trust and create a radically fair economy. Our
platform is decentralized, scalable and secure to settle any transactions
without trusted parties.

🤝 BLOCKCHAIN PROTOCOL: SCALING & SECURITY

Harmony’s vision is to create cooperation for global communities, and scale
their digital economies.
Uniform Scaling on Shard 1 & Economics Games on .1.country
[This is an extended transcript of Harmony’s annual overview and roadmap in Palo
Alto.] Good afternoon, everyone. My name is Stephen, the founder of Harmony.
Today, I’m going to dive deeply into two topics — uniform scaling and economic
games. Part 1 — Uniform Scaling on our Shard 1
https://blog.harmony.one/p/uniform-scaling-on-shard-1-and-economics


1. SECURE, RANDOM STATE SHARDING

Harmony has transcended the blockchain trilemma by bringing the best research to
production. Sharding is proven to scale blockchains without compromising
security and decentralization.
We divide not only our network nodes but also the blockchain states into shards,
scaling linearly in all three aspects of machines, transactions and storage.‍ To
prevent single shard attacks, we must have a sufficiently large number of nodes
per shard and cryptographic randomness to re-shard regularly. Each shard has 250
nodes for strong security guarantee against Byzantine behaviors. We use
Verifiable Delay Function (VDF) for unbiasable and unpredictable shard
membership.
Harmony Protocol Technical Quarterly Report and Roadmap for Q2 2023
Executive Summary In Q1 2023, Harmony Protocol made significant progress in
Stream Sync, State Sync, Cross-Shard Transactions, and Leader Rotation, along
with numerous protocol updates and enhancements. As we move forward into Q2
2023, our roadmap focuses on State Pruning, Light Client development, and
several new initiatives to optimize the Harmony network. However, it is
essential to emphasize that these new incentives are recommendations and will
not be implemented without community involvement and governance voting.

2. EFFECTIVE POS & TOKEN ECONOMICS

Harmony has designed a novel Proof-of-Stake (PoS) mechanism for network security
and economics. Our Effective Proof-of-Stake (EPoS) reduces centralization
and distributes rewards fairly to thousands of validators. Our staking mechanism
supports delegation and reward compounding.
To support 100% uptime but fully open participation, EPoS slashes validators who
double-sign and it penalizes elected but unavailable nodes.Harmony Economics
Model caps the annual issuance at 441 million tokens (about 3% rate in long
term). Our model gives validators a simple and predictable return. All
transaction fees are burnt to offset the issuance, naturally leading to zero
inflation when our network usage becomes high.


3. FAST CONSENSUS, INSTANT FINALITY

Harmony has innovated on the battle-tested Practical Byzantine Fault Tolerance
(PBFT) for fast consensus of block transactions. Our Fast BFT (FBFT) leads to
low transaction fees and 1-block-time finality in Harmony Mainnet.‍
We use Boneh–Lynn–Shacham (BLS) constant-sized signatures to commit blocks in a
single round of consensus messages. We achieve 2-second block time with view
changes in production against adversarial or unavailable leaders.‍ Harmony
Mainnet was launched in June 2019. Our network has produced 41M blocks with 772k
transactions in publicly traded, native ONE tokens.

2023 Harmony Architecture
Introduction Harmony is a blockchain designed to provide fast, secure, and
scalable infrastructure. This article will cover the current state and plans for
Harmony’s architecture. RPC Full Node RPC full nodes serve as the entry point to
the Harmony network. They handle requests for querying information in the
blockchain or processing transactions. In 2020, Harmony transitioned from
original RPC nodes to elastic RPC clusters to handle the increasing volume of
RPC requests. The transition was made to improve the performance and scalability
of the network. However, now that the traffic amount has decreased, we have
transitioned back to the legacy RPC nodes.

4. KEYLESS SMART WALLETS

Resilient. Funds are recoverable through time locks and multiple safety nets. No
single point of failure such as thefts, cracks, loss, censorship or coercions is
catastrophic.
Sufficient. All steps are well defined without delegating to hardware devices or
seed phrases in safety boxes. Users do not need any passwords or rely on
biometrics.
Composable. One-time or low-entropy passwords are useful for small funds.
Multiple authentications can independently boost protection thresholds against
brute-force.
Self-Sovereign. No third parties, government documents, designated guardians,
backup servers or hardware enclaves are necessary. Users have full custody and
self control.
