MoneyGram joins XDC Network as an institutional validator

What a validator does on XDC

XDC Network runs on XDPoS, a delegated proof-of-stake design. Its validators are called masternodes. Our masternode guide covers the setup in full; the essentials, from XDC's own documentation:

Stake and identity

“Masternodes are required to complete a KYC process and stake 10,000,000 XDC,” and “these tokens must be locked in your Masternode wallet” (XDC documentation). A validator is therefore a known, identified operator, which suits regulated companies.

Getting into the active set

“Token Holders stake XDC to vote for Masternode candidates,” and the “Top 108 Candidates become active Masternodes” (XDC architecture docs). Candidates outside the top group wait as standby nodes, which “do not participate in validating transactions and block creation” but are “on standby to fill the role of Validators that drop from network participation” (XDC documentation).

Producing blocks

Active masternodes “take turns proposing blocks (round-robin)” and “sign blocks to confirm” them, with “900-block epochs for validator rotation” (XDC architecture docs). The live epoch length and block time are on our network page.

Rewards

Validators earn XDC for this work. The rate depends on block times and the number of validators, so we compute it live rather than quote a fixed figure: see the estimate above and our staking guide.
