What Alternate Current is

Alternate Current is a free Minecraft: Java Edition mod that changes how redstone dust calculates power and updates blocks. It forms networks from connected wires and distributes power from wires receiving power from outside a network. The project aims to make redstone updates deterministic and less dependent on location while retaining high Vanilla parity. Its README says redstone dust contributes up to 20 times less MSPT with the mod, and that network-level optimizations can lower updates by up to 20%. The README also describes each wire emitting 24 block updates and 6 shape updates when its power changes. These are project performance claims. Listed loaders include Fabric, Forge, NeoForge, Ornithе, and Quilt, with server-side and singleplayer environments supported. Available Minecraft versions and loaders depend on the release; the listed version range includes 1.14 through 1.21.11 and specific 1.21 releases. The project is MIT-licensed and links to its source repository, issue reporting, and a Discord server. The GitHub repository has no detected security policy or published security advisories.
