Introduction

RentHash is Blockware’s peer-to-peer marketplace for renting full mining machines for fixed terms. Instead of buying or operating ASICs, buyers rent a machine for a set period (commonly 30–120 days), receive the machine’s daily Bitcoin production during that term, and Blockware handles hosting, payout routing, and contract enforcement. Sellers receive upfront remittance for the agreed rental. Rentals are time-bound hardware leases and are not transferable or tradeable.

Why RentHash?

RentHash makes mining Bitcoin and acquiring hashrate easier.

• Lower the barrier to mining - Buyers gain access to Bitcoin mining yield without the capital or ops overhead of buying and hosting hardware.

• Provide miners additional liquidity without selling their Miners - Sellers can monetize future production immediately by accepting upfront remittance for a defined rental term.

• Bring transparency to hashrate trades - By standardizing full-machine rentals, measurement, and remittance, RentHash makes hashrate transactions clearer and reduces the need for bespoke OTC arrangements. 

What RentHash Is

RentHash is P2P Marketplace for contracting Hashrate.

• Full-machine rentals - Each RentOffer is for an entire machine (or a bundle) and specifies term, price, and expected hashrate. Typical terms are 30, 60, 90, or 120 days.

• Buyer experience - Buyers receive the machine’s daily BTC production for the rental term while Blockware operates and maintains the rig.

• Seller experience - Sellers receive an upfront payment according to the agreed remittance terms and the fee disclosures on the offer.Sellers also receive a Hosting Credit for the Term. 

• Non-transferable - Rentals are time-bound leases - they are not transferable or tradeable.

• Platform responsibilities - Blockware provision the Rental, manages payout routing through our Pool, and enforces delivery guarantees. 

How RentHash Works

RentHash connects mining hardware owners with short-term hashrate buyers.

1. Sellers list a RentOffer describing the machine, term, and price. Today. sellers can list their hashrate by contacting Sales@blockwaresolutions.com. 

2. Buyers purchase a rental via BTC or supported fiat rails and begin mining immediately.

3. Blockware provisions the Rental and payout routing and operates the rig during the contract.

4. Buyers receive daily BTC production during the term; sellers receive the agreed remittance per contract.

5. At term end Blockware verifies hashrate delivery and applies remediation policies if the rental is under-delivered. (See the Guaranteed Hashrate section below.) 

Guaranteed Work (Hashrate) Delivery 

RentHash guarantees the amount of hashrate delivered over the rental term in a way that is auditable and reproducible.

• Primary unit: TH·day - Blockware measures delivered work in terahash-days (1 TH·day = 1 TH/s for 1 day).

• Measurement approach - Delivered work is computed by integrating effective hashrate across the contract window using pool-reported and rig telemetry. In practice we use daily and hourly time-weighted averages and correctly weight partial intervals that overlap contract boundaries.

• Deterministic remediation - If delivered work is below the contractual target at maturity, Blockware applies a defined remediation policy - typically time extensions to make up shortfalls or operational remediation for larger deficits. 

• Auditability - Live contract summarizes performance. Pool information associated with Hashrate on the pool can be reviewed and downloaded self-service on the Marketplace.

Measurement Model

Why TH·day? TH·day is a simple, intuitive unit: it captures the amount of work produced by a machine over time.

How we calculate delivered work - We sum time-weighted hashrate samples that fall inside the rental period. Daily averages count as one full day; hourly samples are converted into day fractions; and partial buckets are proportionally weighted. 

Payments and Fees

Payment - Blockware collects the payment and provisions the Rental as seller remittance is completed. 

Payment rails - The platform supports Bitcoin, Lightning, and Credit Card. Fee disclosures (commission or transaction fees) are shown on each RentOffer at Checkout.

Seller Remittance - Sellers receive payment upfront and a hosting credit for the term.

What To Expect

For sellers

Immediate liquidity - You receive upfront remittance for the rental term. The amount remitted to the seller is calculated by subtracting both hosting and fees from the offer's total purchase price.

Responsibilities - Sellers are required to keep and maintain operational Miners for a contract. Sellers guarantee the work (Hashrate) delivered as described in the Guaranteed Work (Hashrate) section above. A buyer's contract will automatically be extended to meet the contract terms. 

Protections - In the event an active contract experiences a material loss in work (hashrate) performance, Blockware will seek remediation on behalf of the buyer from the seller in the form of supplemental hashrate from the seller or a refund. 

*Sellers will review, sign and complete Terms of Service before listing. 

For buyers

What you receive - Buyers get the machine’s daily BTC production for the rental term and do not need to manage hardware or hosting.

Remediation & assurance - If the machine under-performs, Blockware’s remediation policy applies so buyers receive the work they paid for. The measurement and remediation process is auditable. 

*Buyers will read, sign and complete the Terms of Service in RentHash at Checkout.

How to List Your Miners for Rent on RentHash

RentHash allows ASIC owners to rent out their mining hashrate to buyers through short-term contracts. This guide walks you through creating a rental offer for your miners.

Step 1: Navigate to Your Miners

1. Log in to your Blockware Marketplace account.

2. From the left navigation menu, go to: My Mining Insights → My Miners

3. Here you will see a list of all miners associated with your account

Step 2: Select a Miner to Rent

Find the miner(s) you want to rent out. On the right side of the miner row, click the $ (Create Rent Offer) icon. This opens the Create Rent Offer configuration window.

Step 3: Review the Miner Details

If needed, click Change Selection to choose different miners.

Step 4: Configure Your Rental Offer

Note: Each duration creates a separate rental offer. Click + Add Another Offer to list several contract options simultaneously.

Step 5: Set Your Energy Rate

Set the Offer Energy Rate using the pricing slider. This is the price the renter pays per kWh of energy consumed.

The slider shows a pricing range based on your hosting electricity cost, expected mining revenue, and market conditions. As you adjust the rate, the table below updates in real time.

Step 6: Review the Offer Economics

The profitability table shows how your pricing affects both the seller and the renter. Key metrics include:

Adjust the slider until the offer reflects your desired margin. Typically, lower prices lead to faster rentals; higher prices lead to a higher margin but slower demand.

Step 7: Review the Offer

Once your pricing is configured, click Review Offers to verify the final listing before publishing.

Check the:

• Contract duration

• Energy rate

• Expected profit

• Selected miners
