About

What Is ICON Network (ICX)?

Apps use ICON to operate cross-chain seamlessly, build momentum and gain reputation. ICON's Cross-Chain Framework simplifies cross-chain development with its easy-to-use xCall messaging standard and connections to secure bridging protocols.

Who Are the Founders of ICON Network?

ICON Network was co-founded by Min Kim, the former chief strategy officer of DAYLI Financial Group, Korea’s largest fintech holding company, and the chief operating officer at Tapas Media, a U.S. digital content distribution platform. He is also an alumnus of Haas School of Business at the University of California in Berkeley. Min Kim incubated ICONLOOP, ICON’s technical partner.

What Makes ICON Network Unique?

ICON's native ICX coin fuels interoperability with a sizeable percentage of all these fees collected in ICX are burned. Apps, written in any programming language, can use the ICON Cross-Chain Framework on a growing list of blockchains.

How Is the ICON Network Secured?

ICON is a delegated proof-of-stake (DPoS) network, which means a majority of stakeholders delegate their share of the network – in this case, ICX – to registered validators that produce blocks and participate in governance. ICON’s DPoS consensus lets non-technical stakeholders benefit from staking without having to set up a node or join a staking pool.

On ICON, ICX holders can stake and delegate ICX to P-Reps – entities that have registered to participate in governing the ICON blockchain. This DPoS implementation offers the best of both worlds – stakers can passively earn rewards, while technical individuals that are actually interested in setting up infrastructure and governing ICON can do so.

The ICON blockchain is governed by Public Representatives (P-Reps). To become a P-Rep, a team or individual must go through an on-chain registration process which includes paying a 2,000 ICX registration fee. Following registration, a P-Rep can start receiving delegation in the form of staked ICX.

  • ICON’s BTP (Blockchain Transmission Protocol) allows interoperability with other blockchains like Ethereum, Binance Smart Chain, and Klaytn.
  • This enables seamless asset transfers and smart contract interactions across different networks.

7. Tokenization & Asset Management

  • ICON can tokenize real-world assets (real estate, stocks, etc.) and manage them on-chain.
  • This helps in fractional ownership, crowdfunding, and secure asset tracking.

8. Voting & Governance

  • ICON’s decentralized governance model allows token holders to vote on network upgrades and proposals.
  • This ensures a community-driven approach to blockchain development.

Conclusion

What blockchain does ICON use? Is it its own blockchain or built on top of another?

ICON operates on its own blockchain, known as the ICON Network. It is not built on top of another blockchain like Ethereum or Solana. Instead, it is an independent blockchain designed to facilitate interoperability between different blockchains and real-world systems.

Key Features of ICON's Blockchain:

  1. ICON Network – A decentralized blockchain that uses a Loopchain consensus algorithm (a variant of BFT-DPoS).
  2. ICON Republic – A governance structure that allows different blockchains (called "communities") to connect and interact.
  3. Interoperability – ICON aims to bridge different blockchains (e.g., Ethereum, Bitcoin, and private chains) through its BTP (Blockchain Transmission Protocol).
  4. Native Token (ICX) – Used for transactions, staking, and governance within the ICON ecosystem.

Comparison to Other Blockchains:

  • Unlike Ethereum L2s (e.g., Arbitrum, Optimism) or Cosmos-based chains, ICON is a Layer 1 (L1) blockchain with its own consensus and governance.
  • It is similar to Polkadot or Cosmos in its focus on interoperability but has its own unique architecture.

Is ICON programmable? Does it support smart contracts or decentralized applications?

Yes, ICON (ICX) is programmable and supports smart contracts and decentralized applications (DApps). Here’s a breakdown of its capabilities:

1. Smart Contracts

  • ICON uses SCORE (Smart Contract on Reliable Environment), its version of smart contracts, which are written in Python or Java.
  • SCORE allows developers to create decentralized applications (DApps) with similar functionality to Ethereum’s Solidity-based smart contracts.

2. Decentralized Applications (DApps)

  • ICON supports the development of DApps across various industries, including finance (DeFi), identity, and supply chain.
  • The ICON Network is designed to be interoperable, allowing DApps to interact with other blockchains via the ICON Bridge (e.g., Ethereum, Binance Smart Chain, and others).

3. Development Tools & Ecosystem

  • ICON SDK (Software Development Kit) – Provides tools for developers to build and deploy SCORE smart contracts.
  • ICON IDE (Integrated Development Environment) – A web-based tool for writing and testing SCORE contracts.
  • ICON Tracker – A blockchain explorer for monitoring transactions and smart contracts.
  • ICON Community & Grants – ICON Foundation supports developers through grants and hackathons.

4. Interoperability & Cross-Chain DApps

  • ICON’s Loopchain consensus algorithm enables high scalability and interoperability.
  • The ICON Bridge allows seamless interaction with other blockchains, enabling cross-chain DApps.

Conclusion

ICON is a programmable blockchain that supports smart contracts (SCORE) and DApps, making it a viable platform for decentralized applications. Its focus on interoperability and scalability makes it competitive with other smart contract platforms like Ethereum and EOS.

How fast are ICON transactions? What is the typical confirmation time and throughput (transactions per second)?

ICON (ICX) transactions are known for their speed and efficiency, thanks to its Loopchain consensus algorithm, which is a variant of Delegated Proof of Stake (DPoS). Here’s a breakdown of ICON’s transaction performance:

1. Transaction Speed (Confirmation Time)

  • Average Block Time: ~2–5 seconds (depending on network conditions).
  • Finality: Transactions are typically confirmed within 2–5 seconds, making ICON one of the faster blockchain networks.
  • Comparison: Faster than Ethereum (12–15 sec) and comparable to Solana (~400–500 ms) but with more consistent performance.

2. Throughput (Transactions Per Second - TPS)

  • Theoretical Max TPS: 9,000–10,000 TPS (as claimed by the ICON Foundation).
  • Real-World TPS: Typically 1,000–3,000 TPS under normal conditions.
  • Comparison:
    • Ethereum (Layer 1): ~15–30 TPS
    • Solana: ~2,000–5,000 TPS
    • ICON: 1,000–3,000 TPS (scalable with sharding)

3. Scalability & Future Improvements

  • ICON is working on BTP (Blockchain Transmission Protocol) and sharding to further improve throughput.
  • The ICON 2.0 upgrade aims to enhance scalability and interoperability.

Conclusion

ICON offers fast transaction confirmations (~2–5 sec) and high throughput (1,000–3,000 TPS), making it suitable for DeFi, NFTs, and enterprise applications. Its performance is competitive with other high-speed blockchains while maintaining decentralization.

How much data can I store on the ICON blockchain? Does it support on-chain data storage?

The ICON blockchain supports on-chain data storage, but the amount of data you can store is limited by the block size and transaction constraints. Here’s what you need to know:

1. On-Chain Data Storage Limits

  • Block Size: ICON blocks have a maximum size of ~1MB (as of the latest updates).
  • Transaction Size: Each transaction can include a limited amount of data (typically a few KB to tens of KB, depending on the transaction type).
  • Storage Cost: Storing data on-chain incurs transaction fees (ICX) and consumes storage space, which may require periodic maintenance (e.g., pruning or archiving).

2. How to Store Data on ICON

You can store data on-chain using:

  • Smart Contracts (SCOREs): Store data in contract storage (key-value pairs).
  • Transactions: Embed small data payloads in transactions (e.g., metadata, hashes).
  • IPFS + ICON: For large files, store them on IPFS and record the hash on-chain.

3. Alternatives for Large Data

If you need to store large datasets, consider:

  • Off-Chain Storage (IPFS, Arweave, S3) + On-Chain Hashes (for verification).
  • ICON’s Decentralized Storage Solutions (if available in the future).

4. Comparison with Other Blockchains

  • Ethereum: ~80 bytes per transaction (EIP-1559).
  • Solana: Larger blocks (~200-400MB), but still limited.
  • ICON: Similar to Ethereum in terms of on-chain storage constraints.

Conclusion

ICON supports on-chain data storage, but for large datasets, a hybrid approach (IPFS + ICON) is recommended. If you need high-capacity storage, consider off-chain solutions with on-chain verification.

Would you like help with a specific implementation (e.g., storing data in a SCORE)?
