Tokenomics

The native token XP powers gas, mining rewards, and Union Staking on the XPHERE network.

Token Parameters

Field	Value
Symbol	`XP`
Decimals	`18`
Wei sub-unit	`1 XP = 10^18 wei`
Initial Supply	1.5 billion XP pre-distributed (XPHERE 1.0 continuity)
Max Supply	5.5 billion XP (1.5B pre-distributed + 4B emitted over 100 years)
Issuance	Minted every 60 blocks; −26.28% per year (×0.7372 every 31,536,000 blocks)
Minted reward split	20% Foundation · 40% Miner · 40% Union
Transaction fee split	50% burn · 20% Union · 20% Miner · 10% Foundation

Supply Composition

The 5.5 billion XP max supply comes from two sources:

Source	Amount	How it enters circulation
Pre-distributed	1.5 billion XP	Carried over for XPHERE 1.0 continuity
Emitted	4 billion XP	Minted as mining and validation rewards over 100 years
Total	5.5 billion XP

note

The Foundation has not published a bucket-level breakdown of the 1.5 billion pre-distributed XP. Whitepaper §5.e documents the ongoing minted-reward split (20% Foundation / 40% Miner / 40% Union) that governs the 4 billion emitted XP — it is not an allocation of the pre-distribution.

Emission Schedule

A fixed reward is minted every 60 blocks (≈ every 60 seconds) and reduced by 26.28% per year (×0.7372 every 31,536,000 blocks). The first reduction has already occurred.

Emission per 60 blocks:
  Year 1 (initial)          → 2000 XP
  Year 2 (current)          → 1474.4 XP
  Year 3                    → 1086.93 XP
  …−26.28% each year, over a 100-year schedule

Each minted reward is split: 20% Foundation, 40% Miner, 40% Union. See Mining Rewards and Whitepaper §5.e.

The Union 40% is a protocol-level allocation paid to Union validator members — the validator group that records blocks on the Main Chain. It is not a pool product, and it is distinct from the Foundation's XP Union Vault staking service at stake.x-phere.com, which pays stakers from the real earnings of the Foundation's own Union node and permanently burns the remainder — see Union Staking.

Transaction Fees and Burn

This section covers where a fee goes once paid. For what an operation costs in the first place — measured gas for transfers, ERC-20 calls, and deployment — see Gas and Transaction Fees.

Transaction fees are not burned in full. Every transaction's fees are split four ways:

Destination	Share	Where it goes
Burn	50%	Permanently removed from circulation
Union	20%	Union validator members
Miner	20%	xpHash Proof Chain miners — see Mining Rewards
Foundation	10%	Ongoing network operations
Total	100%

The 50% burn is permanent. Combined with the 26.28% annual emission reduction, it provides deflationary pressure during periods of high network activity.

note

Fee revenue is separate from minted emission. Miners and Union members each receive two streams: a share of the minted block reward and a share of transaction fees.

See Whitepaper §5.d for the formal burn model.

A second, non-protocol burn comes from the XP Union Vault: at each daily settlement, more than 40% of the rewards flowing into the vault are sent to 0x…dEaD permanently. The public record is at /burn.html.

Where XP Flows

Minted reward (every 60 blocks):
  Foundation                 ← 20%
  Miner (Proof Chain)        ← 40%
  Union (validator members)  ← 40%
                               ───── 100%

Transaction fees (every transaction):
  Burn (protocol)            ← 50%
  Union (validator members)  ← 20%
  Miner (Proof Chain)        ← 20%
  Foundation                 ← 10%
                               ───── 100%

Union Vault settlement (daily, staking service — not protocol):
  Stakers                    ← 60% × (staked ÷ cap)
  Burn (0x…dEaD)             ← everything else

The first two blocks are protocol-level distributions built into the network. The third is the Foundation's XP Union Vault staking service, which redistributes what the Foundation's own Union node earns.

Tracking Supply

Query current circulating supply:

curl -X POST https://rpc.x-phere.com \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"xp_getTotalSupply","params":[],"id":1}'

Or use the supply pages on XPScan or the Tamsa Explorer.
