FAQ's: Basics#

Braiins Hashpower market is a real-time marketplace for buying Bitcoin mining hashrate (SHA-256 algorithm). It allows buyers to acquire mining power without owning physical hardware.

The platform operates as a supply / demand marketplace with an order book model where buyers place bids at their preferred prices. When orders are matched, hashrate is delivered directly to the buyer's specified mining pool.

When you buy hashrate on Braiins Hashpower:

1. You place a bid specifying your price (BTC/EHs/day), budget, and destination pool
2. Your bid enters the order book
3. When your bid is matched, hashrate delivery begins at the specified cost
4. Hashrate is delivered directly to your specified mining pool
5. Your pool receives shares as if you owned the mining hardware
6. Order budget is gradually consumed and once depleted, the order is fulfilled.

Currently, Braiins Hashpower is a buying platform only. Miners cannot directly list their hashrate for sale on the marketplace.

The marketplace uses a dynamic matching algorithm designed to maximize yield:

Bid Priority:

• Price: Higher-priced bids are matched first
• Age: Among bids at the same price, older bids have priority
• Updates reset age: Any modification to a bid (price, budget, speed limit) makes it younger in the queue

Continuous Re-matching:

• The matching algorithm runs continuously as market conditions change
• Bids are constantly re-evaluated against available hashrate
• Hashrate delivery can shift between orders if a higher-priced or older bid becomes eligible
• An order currently receiving hashrate may lose delivery if outbid

Practical Implications:

• To maintain delivery priority, avoid unnecessary order modifications
• Higher prices secure more reliable delivery
• Orders are not guaranteed continuous hashrate - delivery depends on ongoing market conditions

Hashrate is the computational power used to mine Bitcoin. It's measured in hashes per second:

• TH/s - Terahashes per second (10¹² hashes)
• PH/s - Petahashes per second (10¹⁵ hashes)
• EH/s - Exahashes per second (10¹⁸ hashes)

On Braiins Hashpower, prices are typically quoted in sats/PH/day (satoshis per Petahash per day) or BTC/EH/day (Bitcoin per Exahash per day). It's not completely precise, but it's current market standard how to display hashrate units on marketplaces. Entirely correct would be BTC / EH/s / day meaning how many bitcoins does it cost to receive hashrate at 1 EH/s speed per 1 day.

Last price is the market price for mining hashrate. It represents how much buyers pay in average for a unit of hashrate over a period of time.

On Braiins Hashpower, the price is displayed in multiple formats:

• sats/PH/day - Satoshis per Petahash/second per day
• BTC/EH/day - Bitcoin per Exahash/second per day
• USD/EH/day - US Dollars per Exahash/second per day

You can toggle between these display formats in the platform header.

Hashvalue is the theoretical mining income for 1 PH/s per day, expressed in BTC. It is calculated from the current network difficulty and average transaction fees, typically using a 24-hour fee average.

Hashprice is the same value converted to fiat currency (e.g., USD) based on the current BTC exchange rate.

Comparing hashvalue or hashprice to the market price can be useful for arbitrage strategies.

You can direct purchased hashrate to any Stratum-compatible mining pool that meets the platform's compatibility requirements:

• Pool must support Stratum protocol
• Pool must have extranonce2_size of at least 7
• Pool URL format: stratum+tcp://pool.example.com:port

Popular compatible pools include Braiins Pool, and many other major Bitcoin mining pools. The platform validates pool connectivity before order creation.

For detailed compatibility information, see Pool Compatibility below.

#extranonce2_size Requirement

Braiins Hashpower requires destination pools to have an extranonce2_size of at least 7. This technical requirement ensures proper work distribution across the hashrate being delivered.

#How Compatibility Is Checked

When you enter a pool URL in the Braiins Hashpower UI, the platform automatically checks two things:

1. extranonce2_size: Must be 7 or higher (required for all pools)
2. Worker authorization: Uses mining.authorize to verify your username is valid

Important: Authorization checking only works on pools that support it, including Braiins Pool, F2Pool, Luxor, CK Pool, and SBI. Other pools may accept any username during the check but reject it during actual mining. Be careful to enter the correct username format for your target pool.

#Manual Compatibility Check

You can manually check a pool's extranonce2_size using nc and jq:

(echo '{"id":1,"method":"mining.subscribe","params":[]}'; sleep 1) | nc stratum.example.com 3333 | head -1 | jq -r '.result[2]'

Replace stratum.example.com and 3333 with your pool's host and port. The output must be 7 or higher for compatibility.

Note: The public stratum.braiins.com endpoint returns extranonce2_size of 6, but Braiins Hashpower uses a dedicated node with the required size.

#Known Incompatible Pools

The following major pools or services are not compatible due to insufficient extranonce2_size:

• Nicehash
• Miningrigrentals
• Public Pool

#Known Compatible Pools

The following pools are confirmed compatible (at the time of writing):

• Braiins Pool, Braiins Solo
• All other major pools (Antpool, Binance, CK pool, Cloverpool, EMCD, F2pool, Foundry, Lincoin, Luxor, Ocean, Poolin, SBI, Ultimus, ViaBTC)

If your pool is not listed, use the script above to verify compatibility or contact Braiins support.

Key bid parameters:

Additional parameters like price tick size are available via the /spot/settings API endpoint or displayed in the trading interface.

Yes! You can explore Braiins Hashpower using demo mode:

1. Go to hashpower.braiins.com
2. Click Account View
3. Enter demo as your API token

Demo mode provides simulated data including:

• Mock account balance
• Sample current and historical orders
• Simulated transaction history
• Full interface functionality

This allows you to learn the platform without risking real funds.

During the BETA period, the Spot Bid Fee is 0%. This rate may change after the platform exits BETA status.

Fees are deducted from the settled amount during hourly settlement intervals as hashrate is delivered to your pool.
