7.7 Why EVT Is “Practically Finite” (Soft Cap / Stage Unlocking)

Because EVT is an excavation-based token, some people may wonder: “Isn’t it minted infinitely over time?”

This page explains — at a structural level — why EVT can be considered “practically finite.”

What you’ll learn on this page

• A clear answer to the “infinite issuance” concern

• What 5,000 EVT per store means

• The logic of stage-based unlocking (500 → gradual unlocking)

• How this relates to National Pool difficulty (50% / 75% / 90%)

1) Theoretical upper limit (Soft Cap)

SyFu is designed around the concept that, in theory, global merchants (card-accepting stores) are the target universe, and:

each store has a predefined amount of EVT “reserved” in it.

Maximum reserves per store

• Maximum: 5,000 EVT

This is the theoretical upper bound assigned to each store.

How the National Pool is built

A country’s National Pool is formed by:

the total EVT reserved in stores that have been unlocked in that country.

Because the number of stores depends on each country’s merchant base, each country naturally has a theoretical upper limit (soft cap).

2) Only unlocked stores become excavatable in practice

The key point is:

not all theoretically eligible stores are unlocked at all times.

In practice, what becomes excavatable is mainly:

• the portion of stores that users have unlocked using Right Scroll

• the portions that have been unlocked after meeting stage-based conditions

In other words:

• “a large potential store universe” does not mean “instant supply expansion.”

3) Stage-Based Unlocking: The Full 5,000 EVT Is Not Released From the Start

Even though the maximum reserve per store is 5,000 EVT, it is not fully unlocked from the beginning.

Unlocking flow

• Stage 1: Only 500 EVT is unlocked

• After that, based on ecosystem indicators, additional supply is unlocked gradually by +2% to +10%

• Over time, it can reach the maximum of 5,000 EVT

The indicators here are intended to reflect overall ecosystem growth, such as:

• the number of BIND payment records

• NFT prices and trading activity

• broader ecosystem growth signals

Specific indicators and ratios may be adjusted over time to maintain ecosystem stability.

4) National Pool difficulty increase (automatic inflation control)

EVT is controlled not only through “caps,” but also through an automatic pacing mechanism for excavation.

As excavation progresses and a country’s National Pool becomes more depleted, the excavation efficiency (difficulty) changes in stages once certain consumption thresholds are crossed.

• 50%

• 75%

• 90%

As each threshold is crossed, excavation efficiency is reduced.

This mechanism helps ensure:

• the excavation pace slows automatically during potential oversupply periods

• supply pace does not drift too far ahead of ecosystem growth

---

Summary

EVT can be considered “practically finite” for three main reasons:

1. A maximum reserve of 5,000 EVT per store

2. A staged structure where only unlocked portions become excavatable

3. A difficulty adjustment mechanism based on National Pool consumption

EVT is not a simple issuance-based token. It is designed as a structurally controlled model that combines a theoretical upper limit, stage-based unlocking, and difficulty control.
