Mining with rented hashrate
Hashrate marketplaces send their buyers' hashrate to any Stratum V1 pool. These are the settings to use with MergedHash. Renting costs money and blocks are not guaranteed, so treat it as a calculated risk, not an income.
Which port
Rented hashrate arrives through the marketplace's own proxies, often many PH/s on one connection. Use the high-difficulty ports, which start at difficulty 1,048,576 and never go below 262,144:
| Chain | Solo | Shared (PPLNS) |
|---|---|---|
| eCash (ECX) | stratum+tcp://mine.mergedhash.com:3337 | stratum+tcp://mine.mergedhash.com:3339 |
| Bitcoin (BTC) | stratum+tcp://mine.mergedhash.com:3346 | stratum+tcp://mine.mergedhash.com:3349 |
The normal ports (3335/3338, 3345/3348) work too, but they start low and the first seconds produce a flood of easy shares that some marketplaces count against the pool.
NiceHash
In the NiceHash hashpower marketplace, add a new pool under My pools: algorithm SHA256 (or SHA256AsicBoost), host mine.mergedhash.com, port 3337 (or the port you chose), user bc1q…yourAddress.nicehash, password x or x,d=4194304. NiceHash tests the pool when you save it. Then create an order that uses this pool.
MiningRigRentals
Add MergedHash under Pool configuration for your rental (or in your saved pool profiles): host stratum+tcp://mine.mergedhash.com, port 3337, worker bc1q…yourAddress.mrr, password x. For a large rig use a starting difficulty that suits its hashrate, for example x,d=4194304 for 1–20 PH/s. Add a second MergedHash port as a fallback if you like.
Braiins Hashpower
Set the destination pool to stratum+tcp://mine.mergedhash.com:3346 for Bitcoin or :3337 for eCash, user bc1q…yourAddress.braiins, password x. Version rolling (ASICBoost) is supported.
Starting difficulty (d=)
| Rented hashrate | Password |
|---|---|
| up to 1 PH/s | x |
| 1–20 PH/s | x,d=4194304 |
| 20–200 PH/s | x,d=67108864 |
| 200 PH/s and up | x,d=1073741824 |
Vardiff then keeps the connection at about 6–12 shares a minute. Add ,htr=H… to also receive Hathor.
Worker names and tracking
Give each rental its own worker name (.nicehash, .mrr-123, .braiins) so you can see them separately on your miner page. Rewards go to the address before the dot, written directly into each block's coinbase; nothing is credited to the marketplace or the pool.
Solo or shared with rented hashrate
With rented hashrate you pay a fixed price for the rental time, while block rewards depend on luck. On a solo port you get the whole block only if your rental finds it during the rental; over a short rental that may not happen. On a shared port your shares join the recent-shares window (PPLNS) and are paid in later blocks found by the shared port, even after the rental ends, as long as they are still in the window. Read solo vs PPLNS before you rent, and check the current network difficulty on the status page.
Rental questions
Does MergedHash accept NiceHash?
Yes. Use a high-difficulty port (3337/3339 for eCash, 3346/3349 for Bitcoin). The pool supports version rolling and extranonce subscribe.
Will a rental find a block?
Nobody can say. The chance of a block during a rental equals the rented hashrate's share of the network hashrate multiplied by the rental time. Many rentals find nothing.
Who receives the reward?
The address in your worker name, directly in the block's coinbase, minus the 1% pool fee. The marketplace and the pool never hold it.
