CPU mining setup

What is CPU mining?

Yespower and yescrypt families are built so ordinary CPUs stay competitive — GPUs and ASICs don’t dominate the way they do on SHA-256 or Ethash.

You run a miner on hardware you already own: a Raspberry Pi, an old laptop, or a desktop. Your machine talks to a coin node over RPC (or a pool) and hashes blocks.

isekai-pool.com hosts public RPC nodes so you can solo-mine or build tools without syncing a full node yourself. See the status dashboard and API docs.

Install a miner

YTN & TDC: JayDDee/cpuminer-opt. KOTO: KotoDevelopers/cpuminer-yescrypt (not cpuminer-opt — see KOTO card above).

sudo apt update && sudo apt install -y git build-essential automake autoconf \
  libcurl4-openssl-dev libssl-dev libjansson-dev libgmp-dev zlib1g-dev screen

git clone https://github.com/JayDDee/cpuminer-opt.git
cd cpuminer-opt
./autogen.sh
./configure CFLAGS="-O3 -march=armv8.2-a+crypto -mtune=cortex-a76" LIBS="-lcurl"
make -j4

sudo apt update && sudo apt install -y git build-essential automake autoconf \
  libcurl4-openssl-dev libssl-dev libjansson-dev libgmp-dev zlib1g-dev

git clone https://github.com/KotoDevelopers/cpuminer-yescrypt.git
cd cpuminer-yescrypt
./autogen.sh
./configure CFLAGS="-O3 -funroll-loops -fomit-frame-pointer"
make -j4

sudo apt update && sudo apt install -y git build-essential automake autoconf \
  libcurl4-openssl-dev libssl-dev libjansson-dev libgmp-dev zlib1g-dev screen

git clone https://github.com/JayDDee/cpuminer-opt.git
cd cpuminer-opt
./autogen.sh
./configure CFLAGS="-O3 -march=native" LIBS="-lcurl"
make -j$(nproc)

sudo apt update && sudo apt install -y git build-essential automake autoconf \
  libcurl4-openssl-dev libssl-dev libjansson-dev libgmp-dev zlib1g-dev

git clone https://github.com/KotoDevelopers/cpuminer-yescrypt.git
cd cpuminer-yescrypt
./autogen.sh
./configure CFLAGS="-O3 -funroll-loops -fomit-frame-pointer"
make -j$(nproc)

Run the miner

Host 153.75.225.100 — RPC ports: 9982 (YTN), 8432 (KOTO), 9368 (TDC). Credentials: Node Status or your operator. Replace YOUR_RPC_PASS with your real RPC password in a secure environment only.

YTN — solo (cpuminer-opt)

./cpuminer \
  --algo=yespowerr16 \
  --url=http://153.75.225.100:9982 \
  --user=isekai_ytn \
  --pass=YOUR_RPC_PASS \
  --coinbase-addr=YOUR_YTN_ADDRESS \
  --threads=4

TDC — solo (cpuminer-opt)

Same pattern as YTN with --algo=yespowertide and port 9368. See Tidecoin page.

KOTO — pool (recommended)

Use minerd from cpuminer-yescrypt — no -a / algorithm flag needed.

./minerd \
  -o stratum+tcp://koto.isekai-pool.com:3301 \
  -u YOUR_KOTO_ADDRESS.worker_name \
  -p x \
  -t 4

KOTO — solo RPC (advanced)

./minerd \
  -o http://153.75.225.100:8432 \
  -u isekai_koto \
  -p YOUR_RPC_PASS \
  --coinbase-addr=YOUR_KOTO_ADDRESS \
  -t 4
