Scrypt miners can join the pot now

PotPool now has a Scrypt lane. If you run a Scrypt rig, an L7 or anything smaller, you can mine DigiByte into the same pot as the SHA-256d miners.

You earn a share of the same rounds, by the same rule, so a Scrypt rig and a SHA-256d rig doing equal work toward blocks get an equal claim on the winnings.

DigiByte is mined with five algorithms, and each one finds roughly the same share of blocks. Until now I only ran SHA-256d. Scrypt is the second lane, and it pays into the same syndicate wallet: every block from either lane goes 100% into the pot that buys the Megapot tickets.

How to connect

stratum+tcp://scrypt.potpool.party:3334
0xYourBaseAddress.rig1

It works exactly like the SHA-256d port: your Base address is your claim identity, the part after the dot names the rig, and password x is fine. Rigs on both lanes under the same address are added together on your miner page.

Scrypt difficulty uses the Litecoin scale your rig already expects, so the numbers look nothing like SHA-256d ones. Let vardiff find it, or pin one with d= in the password if your marketplace needs a fixed start.

Donating works here too: name the rig donate and its blocks go into the pot without taking any weight. Read more about donating hashrate.

Is it fair to the SHA-256d miners?

This was the part I cared about most. A SHA-256d share and a Scrypt share are not the same unit, and the two networks' difficulties are thousands of times apart. Today SHA-256d sits around 440 million and Scrypt around 180 thousand. Both also swing two or three times over within an hour, because DigiByte retargets every block.

So I don't compare difficulties at all. Every share is credited by its real chance of finding a block: the block target divided by the share target, taken from the exact job the rig was working on. A share with a one-in-a-million chance of solving a SHA-256d block and a share with a one-in-a-million chance of solving a Scrypt block get the same weight. Equal work toward blocks, equal weight in the round.

Each round then multiplies every share by the same number, the SHA-256d difficulty at the moment the round started, just so the weights stay readable whole numbers. It is the same for everyone in the round, so it can't tilt one lane against the other.

What to expect

The exchange rate between the lanes is not fixed. It follows the two networks' difficulties, and those move a lot. On the day I launched this:

A 9.5 GH/s L7 earned between about a quarter and a half of the weight of a 100 TH/s SHA-256d rig.
A small 80 MH/s Scrypt card earned between about a sixth and a third of the weight of a 1.2 TH/s Bitaxe.

Don't read too much into the raw hashrate numbers. A Scrypt hash and a SHA-256d hash are different things, and your share depends only on how much your rig adds to the pool's chance of finding blocks. When Scrypt difficulty drops, every Scrypt share is worth more, and the credit follows it share by share.

Where it shows up

On the home page, SHA-256d and Scrypt hashrate sit side by side, with the share of recent work each lane brings. I never add the two hashrates together, since a Scrypt hash and a SHA-256d hash are different things.
On each round page, a Work by algorithm row splits the round's total work between the lanes.
On your miner page, hashrate is shown per lane and every rig is tagged with its algorithm.

Quick answers

I mine SHA-256d. Do I need to change anything? No. Your port, your username and the way your shares count stay the same.
What if the Scrypt lane has a problem? It runs separately, so SHA-256d mining keeps going whatever happens to it.

Why bother

More hashrate means blocks arrive sooner, the wallet reaches the 1,000 DGB threshold sooner, and tickets get bought more often. A second lane opens the pot to a whole second group of miners, and the credit rule means nobody on either lane is diluted unfairly.

If you have a Scrypt rig, point it at the pool and say hi on Telegram. I would love to see the Scrypt card on the home page light up.
