How does the spacemesh earnings calculator work (SMH)?

The spacemesh is now being traded on We have updated the calculator to reflect the trade value, currently at 0.5 USD per SMH.

Spacemesh has a high reward frequency of 40 blocks per minute, compared to 6 per hour for Bitcoin. The chance of winning smesh is is much higher than bitcoin and offers a fair way of distribution smesh. In order to win smesh there is no need for a race to gain market size. Lower reward distribution as seen with other Proof od Work and new Proof of Space Time networks like chia have caused expontial network growth because participants needed to keep adding storage in order to keep up with the network and see rewards within predictable time frames. The higher spacemesh reward frequency also means there is no need for pools.

Please note that all statements here can change since the spacemesh network hasn’t launched yet.

What kind of hardware do I need for mining spacemesh (SMH)?

Spacemesh is optimized to be run on Home PC’s and does not require specialized hardware. The rewards are however proportionally distributed depending on the size of the storage committed and linked to your spacemesh identity. The commited space will be filled with precalculated hashes. This process can be performed with our CPU of GPU. A recent GPU will perform best in generating the committed space. There is a minimum size requirement of 1TB. More recent GPU’s tend to generate the PoST init file faster that older ones. If you don't have a graphics card yet we recommend the Nvdia GeForce 1660 Super for basic performance (50 hours per TB), the Nvdia GeForce RTX 2070 (40 hours per TB) for good performance and an Nvdia GeForce 1 RTX 3070 (14 hours per TB) for beast mode. GPU PoST file init has not been featured in the spacemesh testnets but there is a GPU post performance test script available. Actual performance might differ as the spacemesh project matures and grows. We will dedicate a full article on CPU and GPU performance once more real life info and test data is available. And unlike other PoST blockchain projects spacemesh does not kill SSD drives.

Nvdia GeForce RTX 3060 - 6 days per TB

Nvdia GeForce RTX 3080 TI - 3,5 days per TB

Nvdia GeForce RTX 4090 - 1.7 days TB

Note that it is important to take the disk storage performance into account. Your system will have to read the whole disk to prove te storage within 12 hours. Network storage is not advisable as it compromises on transfer speeds. Never fully plot the disk, leve some space over.

What is spacemesh (SMH)?

Spacemesh is not a blockchain - it is a mesh of blocks

Spacemesh is based on the concept of a blockmesh rather than a blockchain. The mesh is divided into layers which are sets of blocks. As long as blocks follow the rules they will be included in the mesh. Participants are thus not racing to be the first to create the next block. Using an mesh instead of a chain spacemesh can also efficiëntly create more transactions than other blockchains within a timeframe. This also allows for a more frequent distribution of rewards to participants called smeshers.
Sets of blocks are combined into layers when they are smeshed in the same timeframe. These timeframes are fixed time intervals. Once a layer has been published blocks are processed and checked on validity by a consensus protocol called 'Hare'. The Hare protocol is fast, next to it the 'Tortoise' vote counting protocol is run to finalize block validity. This protocol ensures consenus over the entire history of the ledger.

Blocks are lists of transactions that are added to the ledger and belong to one single layer and to one single smesher. Blocks also contain information about which blocks from previous layers they extend. Each block in a new layer votes for blocks in the previous layer it considers valid. When receiving enough votes a block is included in the ledger.

Spacemesh Smeshers create blocks and provide proof of space time (NiPoST)

In order to run spacemesh users need to set aside diskspace. Instead of using CPU, CPU or ASIC compute power, Disk Space is used as the scarce resource. Millions of people around the world have access to disk space, ensuring fair access. Joining spacemesh is thus bacically costless for a home user, like it was at the beginning of bitcoin mining. Smeshers need to provide prove that the committed disk space was used for the protocol over a designated period of time. It determines the eligibility of a smesher to provide blocks. NiPost provides Proof of Existence and Proof Elapsed Time. Proof of elapsed time is provided by timeservers.

Spacemesh Ensures Fair Access

Spacemesh is a cryptocurrency that aims to provide fair access and a low entry barrier. The currency is supposed to be mined - smeshed is the term here - with entry-level hardware. This low entry barrier should help to achieve decentralisation and a fair distribution of spacemesh. The low entry barrier allows accumulation of spacemesh without having to convert local currency. Its use-case is a means of payment between two parties.

Spacemesh solves problems with current Proof of Work and Proof of Stake blockhains

Proof of work and mining pools make the distribution of currency very centralised. Only persons with enough resources can mint proof of work coins. The entry barrier for Proof of work coins is very high. Combine that with the fact that proof of work is very resource intensive and bad for the environment proof of work is not the right choice to achieve consensus in a blockchain. Prood of stake removes the environmental impact but access to the statking rewards is often difficult because of entry barriers and leads to centralized plutocracies of rich validators.

Spacemesh provides access to fair payment contracts

A third goals of the spacemesh team is to enable fair access to contracts running on spacemesh. Ensuring fair rewards for their work.

Spacemesh requires less energy

Because the scarce resource of the spacemesh blockmesh is composed out of disk space there is less energy required to secure the network. Cost per transaction is estimated at 3 cents per transaction while Bitcoin transactions currently cost $50.

Where can I trade spacemesh (SMH)?

The Spacemesh network isn't live yet, because of this Spacemesh is currently not available on any exchange. As we have seen with other proof of spacetime networkd it might take some time before the assets are tradeable. Subscribe to our spacemesh info mailinglist to be the first to know.
