Ignition Chain is secured by solo stakers, who participate by running nodes, staking $AZTEC, earning block rewards, and helping coordinate block production. Running a validator on Aztec Network requires an 8-core CPU, 16 GB RAM, a 1 TB NVMe SSD, 25 Mbps bandwidth, and 200,000 staked $AZTEC tokens.USX Stablecoin Goes LiveUSX, a privacy-preserving “neodollar” built on Scroll and powered by LayerZero’s OFT standard, is now live.
