IXI Emission Details

Overview

A strong incentive model is essential for maintaining the security and decentralization of the Ixian network. This incentive is delivered through the native cryptocurrency, IXI, which is used for network transactions, fees, and rewards.

The total supply of IXI is determined by two factors:

  1. The Premine: A fixed amount of IXI created in the genesis block to fund initial development, node infrastructure, and long-term project growth.
  2. Inflation: New IXI created in every block and distributed to network participants (Master Nodes and Miners) as a reward for securing the network.

Premine

The genesis block (#1) contains seven transactions that constitute the premine, allocating funds for initial seed nodes, developer rewards, and the foundation.

  • 240,000 IXI to 1AAF8ZagTw6UqiQPUoiKjmoAN45jvR8tdmSmeev4uNzq45QWB: Intended for setting up 12 initial seed nodes (used by seed1.ixian.io).
  • 20,000 IXI to 1NpizdRi5rmw586Aw883CoQ7THUT528CU5JGhGomgaG9hC3EF: Intended for running an Ixian DLT seed node (used by seed2.ixian.io).

  • 20,000 IXI to 1R2WxZ7rmQhMTt5mCFTPhPe9Ltw8pTPY6uTsWHCvVd3GvWupC: Intended for running an Ixian DLT seed node (used by seed5.ixian.io).
  • 1,000,000,000 IXI to 13fiCRZHPqcCFvQvuggKEjDvFsVLmwoavaBw1ng5PdSKvCUGp: Intended to be used as a reward for developers.
  • 1,000,000,000 IXI to 16LUmwUnU9M4Wn92nrvCStj83LDCRwvAaSio6Xtb3yvqqqCCz: Intended to be used by the foundation to further evolve Ixian technology.

The total premine amounts to 2,000,320,000 IXI. Of this, 1 billion IXI for the developer reward is subject to a 5-year vesting period, with 20% released at the end of each year. The other 1 billion IXI is allocated to the foundation for ongoing development, marketing, and other operational activities.

Inflation and Block Rewards

New IXI coins are generated with every new block. These "block rewards" are distributed to network participants via two mechanisms: Signing Rewards and Argon2 Mining Rewards. This process creates a predictable inflation schedule designed to incentivize network security.

Signing Rewards

The signing reward is the primary mechanism for new coin issuance and is distributed to the Master Nodes that validate and sign blocks. The reward structure began with an inflationary model tied to the circulating supply and later transitioned to a fixed schedule with periodic "halvings."

Argon2 Mining Rewards

The mining reward was a legacy mechanism for initial coin distribution. This reward also followed a halving schedule and has a fixed expiration date.
