BEM is the first official on-chain production-tool miner example token of the TapeOut protocol. The goal of TapeOut Protocol is to let a blockchain carry not only financial assets but also verifiable production tools. Developers take the protocol's most basic circuit components, NAND and LATCH (ERC-1155), wire them on a canvas into different logic circuits, and tape a circuit out as an ERC-721 NFT whose netlist is stored on chain and can be executed and verified by anyone. BEM is emitted through Proof of Design (PoD). The maximum supply of BEM is fixed at 21,000,000 with 8 decimals and halves roughly every four years. Only the mining contract can mint it, and that contract has been permanently sealed and can no longer be upgraded; it has no owner, no pause function and no blacklist, and is entirely community held. There was no pre-mine, no team allocation and no whitelist: a fair launch.
