The IRC-3 token standard interface was first proposed in 2018, to standardize the issuance and trading of non-fungible assets on the ICON blockchain.

NFTs represent unique ownership of digital or physical assets that are distinguishable and inherently non-fungible. A diverse universe of assets can be represented by NFTs, including physical properties such as homes, artworks, or virtual assets such as collectible cards and other one-of-a-kind unique assets. Inspired by the ERC-721 standard, IRC-3 covers the broad features of NFT use cases, including ownership representation of digital or physical assets, and consignment to third party operators for token transfers. The standard can be found on the ICON Non-Fungible Token Standard IIP page, including its specifications and a sample SCORE implementation. A community-driven NFT group was also formed during the most recent ICON developer call, where interested community members can gather to collaborate and build around the NFT technology.

CertiK, is the leading blockchain security company, founded by Computer Science professors from Yale and Columbia University. They pioneered using Formal Verification technology to perform comprehensive mathematical computations that are able to identify undetected vulnerabilities in a project’s source code. They have helped secure some of the largest blockchain projects in the space by combining their deep domain expertise, proprietary tooling and unique techniques.

Quick Take:

  1. Transaction fees in USD are currently extremely low, unnecessarily low
  2. With the current average transaction fee, it would take ~43M transactions per day (~500 tps) to break even
  3. With 10x the transaction fee, we could be counteracting inflation entirely with ~4.3M transactions per day (~50 tps)

They propose raising the base transaction fee to 10 times what it currently is over a period of time, making sure it is not causing disruptions in the network along the way. Step Price adjustments are a built-in Network Proposal, so what in necessary to do is make the proposal and agree. However, there is a maximum increase in Step Price of 30% so it will take some time to reach the goal of 10x growth.

  • Release is planned for July 20th according to the roadmap

Awareness and social encounters

Key Highlights:

  1. ~55.2% of circulating supply staked vs. 38.4% at the end of 2019. ~13.7% annual staking reward
  2. +3% weekly growth in wallets with balances. Over 300,000 wallets now have an ICX balance
  3. Main P-Reps lowered the global commission rate to ~17.3% down from ~17.5% last week
  4. ICONLOOP raises 6 billion KRW (~5 million USD) in a bridge round from leading Korean investment firms
  5. ICONLOOP onboards POSCO (a multi-billion dollar company) to the network through the VisitMe app
  6. ICON released its June technology roadmap update including staking from SCORE, multiple unstaking periods and voting up to 100 P-Reps
  7. Cointelegraph covers ICON Hyperhack in an article titled “The Rise of Virtual Hackathons

With the recently released interoperability protocol, BTP 1.0 ICON brings true decentralization to the blockchain by seamlessly connecting public & private decentralized services.

With many sports leagues around the world in a state of suspension because of the COVID-19 pandemic, especially in the United States, you’d think this would be a bad time for sports betting platforms. ICON-powered sports betting DApp ZenSports, however, has not only adjusted to the new reality, but is flourishing in it. ZenSports Mark Thomas says traffic is on par with pre-pandemic times, in part thanks to the additions of newer sports such as MMA and esports. It took some effort on the part of ZenSports and users themselves to get there, though.

He adds, “Sometimes, you’re forced to learn something new. And you learn that you love it.”

Min Kim, ICON founder, tweeted “ICON ranks quite well overall vs. other top smart contract platforms. Have room to improve, esp. market maturity category.”

They will also update ICONex Chrome, ICONex Mobile, and ICON Tracker to support the new features.

[Update details]

Based on community requests, they have worked on several features to enhance the governance experience of the ICON network. Based on this feedback, they will soon add P-Rep private key dualizing, staking, and delegating functions in SCORE, multiple unstaking periods, and a function to increase the number of delegations from 10 to 100. Details of each feature can be found below.

[P-Rep Private Key Dualizing function]

  1. Allows P-Reps to register an additional key, the key used to produce and validate a block, to the ICON Network.
  2. Currently, when an ICONist tries to register as a P-Rep, the ICONist’s key will automatically be registered as a key for the node, and the keystore has to be put into the docker.
  3. With this update, ICONist can register a separate additional key for P-Rep nodes when they try to register as a P-Rep.
  4. The ICONist public address will be used to participate in governance, receive reward, and only the node key you have registered are included in the docker.
  5. Therefore, the ICONist’s public key does not enter the docker, but only the key of the node enters the docker. It can be understood that the owner of the node and the key for node operation are separated.

[Staking and delegating function in SCORE]

  1. Allows SCORE to stake and delegate directly to P-Reps.
  2. Since ICON Network has a block reward for voting, if a SCORE can vote to a P-Rep, the SCORE also can receive a reward and distribute it to the ICONists who deposited ICX to the contract.

[Multiple Unstaking Periods]

  1. Allows ICONists and SCOREs to have separate schedules for unstaking.
  2. Currently, an ICONist can only submit one unstaking request to the network. With this update, ICONist will be able to submit several unstaking requests (up to 1000).

[Extension of the number of delegation slots]

  1. Allows an ICONist to vote up to 100 P-Reps.

[Additional developments during the month]

They continued to make progress on additional IRC token standards for the ICON network. They hope to release more information on these standards in the coming weeks.

Partnerships and team members

Danal Holdings (Subsidiary of Danal — software development, commerce, mobile payment) has decided to invest in ICONLOOP. They intend on using DID for integrated payment system and identification services on their platform.

Check a thread by Markus from ICON Hyperconnect:

Balanced is a DAO consisting of a decentralized balance sheet of ICX collateral, with the vision of creating a vibrant ecosystem of tokens pegged to the value of real-world assets. It allows users to mint and retire pegged assets, while also providing market makers with clearly defined arbitrage opportunities. The initial iteration of Balanced will support the minting and retiring of USD-pegged assets referred to as ICON Dollars (ICD).
