🌈 The Power of Sharding: Unlocking Harmony's Potential 🚀

In the fast-paced world of blockchain technology, scalability has always been a key challenge. The holy trinity of decentralization, scalability, and security has been an elusive goal for many projects. But fear not, for there is a shining star in the blockchain galaxy that aims to conquer this trilemma with its unique combination of features - Harmony!

🏰 The Genesis of Harmony 🎉

Founded in 2018 by the visionary Stephen Tse, Harmony set out on a mission to redefine the blockchain landscape. After a successful mainnet launch in 2019, Harmony has been on a relentless journey to revolutionize decentralized applications (DApps) with its cutting-edge technology.

The team behind Harmony comprises more than 30 members, each bringing their expertise in engineering, academic research, and entrepreneurship. Led by Stephen Tse, this dream team is the driving force behind Harmony's innovation.

💡 Understanding Sharding and Effective Proof of Stake (EPoS) 🧩

Harmony's secret weapon against the scalability trilemma is the power of sharding and its Effective Proof of Stake (EPoS) consensus mechanism. Sharding is like dividing the blockchain into smaller pieces, or shards, allowing multiple transactions to be processed in parallel. This results in high throughput, low latency, and a more scalable network.

Sharding has emerged as one of the methods by which blockchain developers aim to increase transaction speeds of blockchain-based platforms. The concept rests on an approach already used in databases to improve their efficiency. One of the best-known implementations of sharding in the crypto world is the one used with Zilliqa. Each of its shards is capable of processing a fraction of the totality of transactions taking place on the Zilliqa network. The platform thus profits from the increased number of shards on it, as the transaction can be managed by more units that take care of them.

Supposedly, the problem the Harmony developers have with this approach is that it does not include the division of the blockchain data storage. This prevents the devices with limited access to resources from participating in the network and increases the risk of single-shard takeover attacks. Instead of this, Harmony proposes the deep sharding of the blockchain state.

🚀 Harmony's Deep Sharding Approach 🧱

This approach involves sharding on both the transaction and consensus layers. Based on this, the nodes can identify other nodes that can play a role in the transaction and make transactions only with them as part of the consensus-building procedure. This is supposed to improve the parallel processing capacity and, in turn, throughput performance of the platform.

Harmony currently has a limit of 250 validators slots per shard known as BLS Keys. If needed, the number of shards and validators can increase to meet network demand in the future. Shard 0 is the Beacon Chain and acts as an information relay between shards 1, 2, and 3. No matter the shard used, transaction times will be roughly two seconds.

Currently, most activity takes place on the Beacon Chain. Full cross-shard implementation isn't yet fully developed but is on the roadmap. In the future, cross-shard communication will allow for smart contracts to operate across shards by transmitting messages between nodes directly.

🔒 Decentralization and Security - Harmony's Forte 🔒

Harmony's EPoS also promotes decentralization by discouraging centralization of power among validators. This ensures that the network remains secure and resilient against potential attacks. Sharding further strengthens security by distributing the network's workload among validators, delegators, and users.

Effective Proof of Stake (EPoS) is similar to the standard Proof of Stake (PoS) validator and delegator model. Validators stake ONE (Harmony's native token) to run a node and possibly process transactions through an election process. Delegators stake their ONE behind a validator in return for a percentage of future block rewards and transaction fees. Once elected and assigned a shard, the validator creates blocks and shares its rewards with delegators.

EPoS’s reward distribution is what makes it different. Most PoS systems consolidate rewards and power behind a small number of validators. The more you stake, the more you earn and validate. In contrast, EPoS reduces rewards and penalizes validators who stake too much in a single node. Nodes with smaller stakes actually receive more favorable rewards in relation to their size, encouraging large validators to decentralize. This system also helps avoid single points of failure.

Besides offering a secure method for validating transactions, EPoS provides low gas fees. This makes it an attractive alternative to Ethereum's high gas fees or Bitcoin's scalability issues with Proof of Work (PoW).

💸 ONE Token - The Heart of Harmony 💰

Harmony's native token, ONE, plays a central role in the ecosystem. It fuels transactions, governance decisions, and staking activities. You can get your hands on ONE through various exchanges like Binance, and once you have it, you can securely store it in EVM-compatible wallets like MetaMask and Binance Chain Wallet.

The Harmony protocol's native token ONE is used for:

Paying network transaction fees.
Staking as a delegator or validator in return for block rewards.
Taking part in Harmony's open governance mechanism.

Harmony provides a constant reward to validators of 441 million ONE annually. Transaction fees are burned with an end goal of creating a net-zero state, offsetting the ONE provided for block rewards.

Harmony is not just about blockchain; it's about changing lives. The project envisions a Universal Basic Income (UBI) system based on personal data sharing. Imagine being rewarded for sharing your data with advertisers, retailers, or media, disrupting the current data-sharing monopolies.

Harmony found itself at the heart of the propositions to introduce the Universal Basic Income (UBI) based on the personal data sharing. The data would be shared in exchange for payment provided by advertisers, retailers, or the media, all with the help of the Harmony blockchain. The proceeds would serve as a supplementary or basic income, followed by the dismantling of the current data-sharing monopolies.

🌐 Harmony - Bridging the Gap with Cross-Chain Finance 🌉

In the world of blockchain, interoperability is the name of the game. Harmony embraces this concept with its Cross-Chain Finance model, allowing seamless asset transfers between Harmony, Ethereum, Bitcoin, and more. It's like building bridges across different blockchain realms!

Harmony's Cross-Chain Finance model is one of its key features, allowing users to transfer assets between Harmony and Ethereum. The Horizon bridge facilitates this process, providing a secure and trustless connection between the two blockchains.

🚀 Harmony's Diverse Partnerships - Expanding the Ecosystem 🤝

Harmony has spread its wings far and wide, partnering with various projects to leverage the power of its infrastructure. From gaming with Animoca to health with Lympo, content creation with Contentos, and even calendar services with Timeless, Harmony is leaving no stone unturned to support innovative DApps.
