Tokenomics

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

Supply Composition​

The 5.5 billion XP max supply comes from two sources:

SourceAmountHow it enters circulation
Pre-distributed1.5 billion XPCarried over for XPHERE 1.0 continuity
Emitted4 billion XPMinted as mining and validation rewards over 100 years
Total5.5 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​

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

DestinationShareWhere it goes
Burn50%Permanently removed from circulation
Union20%Union validator members
Miner20%xpHash Proof Chain miners — see Mining Rewards
Foundation10%Ongoing network operations
Total100%

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.
