ICON, a protocol of interconnected networks aggregating blockchain information into one layer, right now introduced the launch of a model new blockchain venture coming to ICON.

This new blockchain, designated ICE, will carry a few new utility hub for the ICON ecosystem. Upon completion, ICE will present builders higher tooling, EVM and eWASM compatibility, and speedy entry to the rising ETH and Polkadot ecosystems.

“ICE additionally represents a shift within the course of the ICON venture by separating performance, product focusing on, and the aim of every of those respective networks. ICE will grow to be the applying hub of the ecosystem whereas we double down on our efforts to make ICON the main cross-chain and interoperability protocol within the business. With ICON, customers will be capable to wrap belongings, natively swap belongings utilizing every respective community’s underlying safety, question information between networks, and extra. Our objectives might be to push these boundaries by continued analysis and improvement of Blockchain Transmission Protocol (BTP) and centered integrations driving its adoption. ICON isn’t a competitor, it’s an enabler. It’s agnostic, and as crypto grows, ICON does as nicely.”

In partnership with Parastate, a Substrate-focused improvement workforce specializing in constructing complicated digital machine pallets, the ICON Community will obtain each EVM and eWASM compatibility by a custom-made and novel Substrate based mostly side-chain.

Whereas others have used the Substrate SDK to construct an app or feature-specific parachain for Polkadot; ICON is the primary workforce to make use of the Substrate SDK to increase the feature-set of an present layer-1 blockchain.

The principle function of this new blockchain is the addition of EVM compatibility to the ICON ecosystem.

EVM compatibility permits builders to iterate and innovate a lot quicker utilizing present tooling and code from the Ethereum ecosystem. It additionally permits for elevated development prospects of ICON given simpler portability of apps. On ICE, ICON can also be including eWASM help; getting ready ICON for ETH 2.0 compatibility.

Along with Parastate, there are quite a few different groups engaged on ICE, with the purpose of rising the developer base, main integrations, and driving exercise.

Breakdown: ICON ecosystem

The ICON Ecosystem will now be cut up between two networks with differing objectives:

First, the ICE blockchain might be centered on the app layer; as it’s a lot simpler for present blockchain builders to leverage the instruments and codebase of EVM appropriate networks. Moreover, functions will be capable to port over their providers shortly to make the most of ICON’s devoted person base.

Second, the present community will proceed to optimize for ICON’s Blockchain Transmission Protocol (BTP) and start focusing particularly on interoperability plus low-latency cross-chain apps. The core focus will grow to be rising integrations of different networks and driving volumes by BTP.

Impression on ICX token holders

The ICE blockchain’s native token, ICE, might be airdropped 1:1 to all ICX holders. All ICX holders on the time of the snapshot will obtain ICE tokens equal to the quantity of ICX they maintain.

Via the usage of ICON’s BTP, ICX would be the governance token of the ICE community. ICX might be used to vote for validators, much like how it’s used for (P-Reps) on the present community.

ICX holders will switch ICX to the ICE community by way of BTP, stake their ICX, vote for validators, and earn ICE tokens as rewards. Whereas ICX would be the governance token, ICE would be the gasoline token of the ICE blockchain.

Moreover, this supplies an early use case for BTP. The ICON Community will earn charges as customers ship ICE and ICX between the ICE Community and the ICON Community; creating additional financial ties to the ICX token. All charges earned from BTP transactions are despatched to ICON’s Contribution Proposal System or burned.

The structure of the ICE blockchain

The ICE blockchain will begin as a Proof of Authority community, with trusted validators working the chain.

After the community is stabilized, it would migrate to NPoS, the consensus mechanism generally utilized by different Substrate SDK networks. NPoS is a variation of DPoS (ICON Community’s present consensus mechanism), the place token holders vote for validators to provide blocks and govern the community.

Sensible contracts on the ICE Community might be written in Solidity, Rust, and C++. Charges for sensible contract interactions, sensible contract deployments, and token transfers might be paid in ICE tokens. 20% of the transaction charges of the community go to Parastate as a part of using their expertise.

The preliminary provide of ICE tokens might be 25% greater than the provision of ICX, with this further 25% being put aside to incentivize future core contributors to the ICE blockchain. It will likely be inflationary to incentivize voting and block manufacturing much like the ICON Community.

Inflation charges and extra detailed economics might be supplied by the ICON workforce after extra analysis into the Substrate SDK. Nevertheless, ICON says it would goal a 5% or 6% most inflation fee at launch.


Proper now, the plan is to have the ICE blockchain absolutely operational with BTP connections by This fall of 2021. The preliminary proof of idea community might be reside in Q3 2021, permitting DApp builders to start constructing EVM and/or eWASM functions earlier than full completion.
