IOST is an enterprise-level blockchain platform that’s unique in its prioritization of scalability naturally and user-facing simplicity. Its goal is to drive adoption of decentralized applications (dApps) and blockchain-powered technology in real-world use cases. IOST has a total supply of 90 billion tokens, with about 22 billion in circulation. To increase performance and usability, IOST takes advantage of a number of unique features such as Efficient Distributed Sharding (EDS), the Proof-of-Believability (PoB) consensus mechanism, Layer 2 rollups, a decentralized identity system and an account naming system. Combined, these features dramatically improve IOST’s ability to process thousands of transactions per second. This has led to a flourishing environment for decentralized applications. The platform’s unique decentralized architecture is backed by more than 400 nodes. This design provides several layers of robustness and reliability, making it an ideal choice for developers and users seeking a scalable, user-friendly blockchain solution. IOST is committed to accessibility. It’s available in several languages, including English, Korean, Chinese, and Japanese, to connect with a worldwide audience.

IOST’s technical architecture is a testament to its commitment to addressing scalability challenges. Its design choices prioritize usability, which will further pave the way for blockchain to reach the mainstream. IOST has applied the state-of-the-art scaling technologies and intuitive user systems. This unified approach not only enhances the experience for developers and end-users, but lays the foundation for a robust decentralized ecosystem.

The following sections explore the key aspects of IOST's architecture, consensus mechanism, and unique features, highlighting how they contribute to the platform's overall scalability, efficiency, and user-friendliness.

Scalability Solutions: Efficient Distributed Sharding and Layer 2 Rollups

IOST addresses the blockchain scalability problem by introducing its Efficient Distributed Sharding (EDS) technology. Sharding, at its core, breaks the blockchain network into smaller, more manageable shards, with each shard able to process transactions autonomously. This parallel processing increases the network’s overall throughput. Consequently, IOST is able to handle up to 8000 transactions per second.

EDS does a great job of evenly distributing the workload amongst its shards. This strategy stops at least one shard from being a potential bottleneck. This intelligent, real-time redistribution of resources maximizes efficiency and keeps the network running at peak performance, even at the most extreme network congestion. The outcome is a blockchain platform that can truly scale to meet the ever-increasing demands of decentralized applications.

IOST uses Layer 2 rollups to increase scalability and lower transaction fees. Layer 2 solutions operate atop the main blockchain, often referred to as Layer 1. They batch a ton of off-chain transactions and prove them to the mainnet in one shot, making it efficient. This method offloads much of the burden from the primary chain, resulting in quicker transaction confirmation and lower costs. IOST’s unique Layer 2 framework increases scalability while decreasing high transaction costs. That makes the platform less intimidating and expensive, setting the stage for downstream real-world adoption over an ever-increasing variety of use cases.

Consensus Mechanism: Proof-of-Believability (PoB)

IOST uses an original consensus algorithm – Proof-of-Believability (PoB) to achieve a fine balance between decentralization and efficiency. PoB distinguishes itself even from other consensus mechanisms like traditional Proof-of-Work (PoW) and Proof-of-Stake (PoS). Rather, it picks validators based on their contributions and reputation to the overall IOST ecosystem—rather than simply their computing power or token wallet. This model promotes deeper engagement and investment in the network, creating a more collaborative and connected community.

The PoB consensus mechanism considers the following aspects to rank the nodes. These are things such as their history, trustworthiness, and the amount of IOST tokens in their ownership. Nodes that have a higher combined “believability” score are more likely to be selected as validators. This smart choice makes it possible for them to get rewards for taking part in the consensus process. Instead, this system gives users the tools to deter dangerous behavior. If a node acts maliciously or otherwise tries to cheat the system, they will lose their “believability” score and thus their chance to take part in validation.

The PoB consensus mechanism secures and stabilizes the IOST network as it gets stronger. Most importantly, it helps create a more equitable distribution of power and rewards. PoB focuses on contribution and reputation rather than token amounts alone. Such an open, participatory process enriches the community, fosters engagement, and builds a healthier, more sustainable blockchain ecosystem.

User-Friendly Features: Decentralized Identity and Account Naming

IOST places a strong emphasis on user experience, recognizing that ease of use is crucial for driving the adoption of blockchain technology. IOST includes a number of other user-friendly features. These features range from a native decentralized identity system to an intuitive account naming convention.

With IOST’s decentralized identity system, users can securely and privately control their digital identities in the blockchain world. This approach provides users with more agency over their data and minimizes their dependence on a handful of centralized identity providers. By leveraging blockchain technology, IOST's decentralized identity system ensures that users' identities are tamper-proof and resistant to censorship.

Their account naming system is very intuitive and simple to work with. It allows users to easily create and control their IOST accounts with no friction. Usernames are the easiest to remember and share since they’re almost always 5-11 characters. This convenient system allows you to quickly send and receive IOST Tokens. Users can simply use their friends’ usernames instead of complicated wallet addresses! IOST’s PayPIN is the convenient payment instrument customers expect. It offers users unmatched flexibility and convenience to transact within the social platform.

Additionally, IOST is currently available in several languages such as English, Korean, Chinese, and Japanese, allowing the platform to be used by a worldwide audience. That kind of multilingual support is a huge user experience win. It helps to spread IOST into other global multicultural communities.
