Postern Pool · Bloch mining

SHA-256d mining for the post-quantum base chain.

Bloch hashes exactly like Bitcoin — double-SHA-256. Point any BTC ASIC, GPU, or CPU miner at Postern Pool and mine straight to your own bloch1q… address. Non-custodial by construction: the pool never holds your coins.

How to connect Why SHA-256d

Connect a miner

Point hashrate at the pool

Standard Stratum V1. Works with any SHA-256d miner. The one rule that trips people up: your username is your bare Bloch address — no worker suffix.

Pool URL: stratum+tcp://stratum.posternpool.com:3336
Username: your own bare bloch1q… address — NO worker suffix
Password: x (any value; ignored)
Algorithm: sha256d

Do NOT append a worker name. The pool expects a bare address as the username. Sending address.worker is rejected with invalid address: expected 48. Use bloch1q… alone — nothing after it, no dot, no rig name.

Bitcoin ASIC — Antminer / Whatsminer / Bitaxe (pool config)

# In the miner's web UI, add a pool:
URL      stratum+tcp://stratum.posternpool.com:3336
Worker   bloch1qyour_own_address_here   # bare — NO .worker
Password x

GPU — ccminer

ccminer -a sha256d \
  -o stratum+tcp://stratum.posternpool.com:3336 \
  -u bloch1qyour_own_address_here \
  -p x

CPU — cpuminer / minerd

minerd -a sha256d \
  -o stratum+tcp://stratum.posternpool.com:3336 \
  -u bloch1qyour_own_address_here \
  -p x

Get an address first

# From your Bloch node / wallet:
bloch-cli getnewaddress
# -> bloch1q…  (this is your -u username)
# Rewards are paid to THIS address. Keep the key.

Why SHA-256d

Bitcoin-class hashrate, securing a quantum-resistant base.

ASIC-honest by design. Bloch uses the same double-SHA-256 as Bitcoin, so the enormous existing pool of SHA-256d ASICs can be pointed at it directly. No novel PoW to game, no hidden ASIC advantage — the honest incumbent hardware just works.
Proof-of-work, all the way down. Coins don't vote; hashrate secures. Bloch is a pure-PoW, fair-launch base — the post-quantum signature layer sits on top of the same battle-tested mining economics that secure Bitcoin.
Decentralization is a verb. Running a node and pointing hashrate at it is how the network spreads out. Do povo, para o povo — from the people, for the people. Every independent miner is one more root the base can't be pulled up by.

Pool proxy tech

Self-hostable. Non-custodial. Yours.

Postern Pool runs on bloch-pool-proxy — a lean Stratum front-end you can run yourself. Don't trust our pool? Run your own against your own node.

Extranonce partitioning

Each connection gets a distinct search space — many miners, no wasted or colliding work.

Vardiff

Per-connection difficulty auto-tunes from a Bitaxe to a full ASIC farm, keeping share rates sane.

PPLNS payouts

Pay-per-last-N-shares rewards sustained contribution and resists pool-hopping.

Non-custodial

The block template pays your address directly. The proxy coordinates work — it never takes custody of coins.

Bring your own node

Point the proxy at any Bloch node's RPC. No middleman between you and the chain.

Open by default

Same Stratum V1 any BTC-class miner already speaks — nothing proprietary to install.
