# Setup Local Devnet Build the Lotus Binaries in debug mode, This enables the use of 1024 byte sectors. ```sh make debug ``` Download the 1024 byte parameters: ```sh ./lotus fetch-params --proving-params 1024 ``` Pre-seal some sectors: ```sh ./lotus-seed pre-seal --sector-size 1024 --num-sectors 2 ``` Create the genesis block and start up the first node: ```sh ./lotus-seed genesis new localnet.json ./lotus-seed genesis add-miner localnet.json ~/.genesis-sectors/pre-seal-t0101.json ./lotus daemon --lotus-make-genesis=dev.gen --genesis-template=localnet.json --bootstrap=false # TODO Key import ``` Set up the genesis miner: ```sh ./lotus-storage-miner init --genesis-miner --actor=t0101 --sector-size=1024 --pre-sealed-sectors=~/.genesis-sectors --nosync ``` Now, finally, start up the miner: ```sh ./lotus-storage-miner run --nosync ``` If all went well, you will have your own local Lotus Devnet running.
