ICON prepares launch of EVM and eWASM-compatible blockchain: ICE


ICON, a protocol of interconnected networks aggregating blockchain information into one layer, at this time introduced the launch of a model new blockchain challenge coming to ICON.

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

“ICE additionally represents a shift within the course of the ICON challenge by separating performance, product concentrating 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 trade. With ICON, customers will have the ability to wrap property, natively swap property utilizing every respective community’s underlying safety, question information between networks, and extra. Our targets will likely be to push these boundaries via continued analysis and growth 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 growth group specializing in constructing advanced digital machine pallets, the ICON Community will obtain each EVM and eWASM compatibility via a personalized and novel Substrate primarily based side-chain.

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

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

EVM compatibility allows builders to iterate and innovate a lot sooner utilizing current tooling and code from the Ethereum ecosystem. It additionally permits for elevated progress prospects of ICON given simpler portability of apps. On ICE, ICON can be including eWASM assist; making ready ICON for ETH 2.0 compatibility.

Along with Parastate, there are quite a few different groups engaged on ICE, with the objective 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 targets:

First, the ICE blockchain will likely be centered on the app layer; as it’s a lot simpler for current blockchain builders to leverage the instruments and codebase of EVM suitable networks. Moreover, functions will have the ability to port over their providers rapidly to benefit from 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 via BTP.

Influence on ICX token holders

The ICE blockchain’s native token, ICE, will likely 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.

By means of the usage of ICON’s BTP, ICX would be the governance token of the ICE community. ICX will likely be used to vote for validators, just 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 offers 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 should 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 will likely be written in Solidity, Rust, and C++. Charges for good contract interactions, good contract deployments, and token transfers will likely 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 will likely be 25% larger than the availability of ICX, with this further 25% being put aside to incentivize future core contributors to the ICE blockchain. Will probably be inflationary to incentivize voting and block manufacturing just like the ICON Community.

Inflation charges and extra detailed economics will likely be offered by the ICON group after extra analysis into the Substrate SDK. Nonetheless, ICON says it should 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 autumn of 2021. The preliminary proof of idea community will likely be reside in Q3 2021, permitting DApp builders to start constructing EVM and/or eWASM functions earlier than full completion.
