Cros said on Monday it is pursuing a “Mainnet 2.0 (Breakpoint)” upgrade that will overhaul both its mainnet operating model and token distribution structure.

The core is to reorganise network operators around validators and to link token rewards to actual participation rather than simple holdings. The foundation said it sees a strengthening trend toward institutionalising digital assets, centred on the United States’ Clarity Act and other moves. It said it will pursue the Mainnet 2.0 upgrade before those changes fully take hold.

◆Simultaneous overhaul of operations and distribution; PoSA shift is the starting point

The starting point of the overhaul is a change in the operating structure. Cros plans to shift to a PoSA (Proof of Staked Authority) model validated on BNB Chain. Under this approach, validators stake assets directly, operate nodes and validate blocks. The foundation said this will build an operating structure that links responsibility and rewards.

Cros said the operating overhaul is intended to change the token distribution method as well. It already applies a “zero minting” policy under which no additional tokens are issued at the mainnet level. As a result, participation rewards come not from new issuance but from within an existing predetermined allocation. It said 60 percent of total supply is set aside as a participation-based distribution pool, and 5 percent is allocated for ecosystem expansion.

Users can participate in the network by delegating tokens to validators they trust rather than simply holding them, and receive block rewards generated as a result. The foundation named this the “Delegate and Reward” model and said it will distinguish between staking-based rewards and contribution rewards based on gas usage. It underscored that rewards are not discretionary incentives but the product of network participation.

The distribution schedule is designed with a halving structure in consideration of long-term sustainability. The first-year block distribution starts at 300 million Cros and then halves each year. It is designed to give a relatively larger share to participants who join early and contribute to ecosystem growth. The foundation said, however, that these figures do not mean returns are guaranteed.

◆100 percent burn of gas fees; April 15 vote, June 1 launch

In terms of token economics, the gas-fee processing method will also change. Cros will introduce a structure that permanently burns 100 percent of the base fee generated on the mainnet. It is designed so that the greater the network usage, the stronger the pressure for the circulating supply to decrease. By contrast, the priority fee paid additionally by users will be paid directly to validators. The foundation plans a dual structure that burns the base fee while directing the priority fee to validator rewards to secure both scarcity and operating incentives.

The burn mechanism will apply from June 1, the scheduled launch date for Mainnet 2.0, and all gas fees accumulated up to that point will also be fully burned at launch.

The upgrade process also includes community participation procedures. Cros plans to put the Breakpoint transition to the community through a staking-based vote for 72 hours starting on the 15th. Network participation aggregation will begin on April 15, and block rewards will be calculated from when staking for voting begins. The foundation plans to pay a lump sum of 45 days’ worth of block rewards in line with the June 1 mainnet launch.

The foundation said the upgrade is not a simple replacement of technical structure but a redesign of operating authority and the reward system around participation. It plans to proceed with distribution within existing supply without new issuance and add a gas-fee burn structure so network activity is directly linked to token economics. The foundation said the related structures and functions may be revised, halted or changed depending on future development progress and the foundation’s official review and approval procedures.
