Public mining opens on
Parameters
| Target block time | 75 seconds |
|---|---|
| Block reward (era 0) | 6.25 coins |
| Halving interval | 1,680,000 blocks — about 4 years |
| Maximum supply | 20,999,987.3152 coins |
| Closed start | Until 31 October 2026, 15:42 UTC only the project's own machines can mine: in those 29 days about 33,408 blocks are produced, about 208,800 SWM (80% to the project's mining wallet, 20% to the three funds), about 0.99% of the cap. From then until 1 November 2026, 15:42 UTC the people on the waiting list can mine too; from that moment mining is open to everyone and the node software will be published on this site. Why: the infrastructure around the coin, liquidity pools included, needs coins before public mining begins; the aim is an orderly, predictable start. The genesis block itself holds no coins. |
| Coinbase maturity | 100 blocks |
| Proof of work | Equihash 200,9, inherited unchanged. Once mining is open to everyone, nothing in the rules keeps larger miners out. |
| Privacy | Optional. Shielded transactions keep sender, receiver and amount encrypted on-chain, using zero-knowledge proofs. |
| Code | Proven open-source code, with consensus rules and cryptography left unmodified. Read it, build it, check it. |
| Ticker | SWM |
| Status | Mainnet, live since 2 October 2026, 15:42 UTC. |
Emission
An era is the stretch between two halvings: 1,680,000 blocks, or roughly four years at a 75-second target block time. In each era the block reward is half of what it was in the era before, which is why the total supply approaches 20,999,987.3152 coins without ever reaching it.
| Era | Block heights | Block reward | Issued in era | Cumulative supply |
|---|---|---|---|---|
| 0 | 1 – 1,679,998 | 6.25 | 10,499,987.5 | 10,499,987.5 |
| 1 | 1,679,999 – 3,359,998 | 3.125 | 5,250,000 | 15,749,987.5 |
| 2 | 3,359,999 – 5,039,998 | 1.5625 | 2,625,000 | 18,374,987.5 |
| 3 | 5,039,999 – 6,719,998 | 0.78125 | 1,312,500 | 19,687,487.5 |
| 4 | 6,719,999 – 8,399,998 | 0.390625 | 656,250 | 20,343,737.5 |
Mining rewards mature after 100 blocks before they can be spent. The genesis block contains no spendable coins, so every coin in the table above has to be mined.
Reward allocation
Every block reward is split four ways, in the same proportions, for the whole emission schedule. Each halving reduces all four amounts together — the 80 / 8 / 4 / 8 structure never changes, all the way down to the block where the reward reaches zero. In the last eras integer rounding retires the small streams first: Grants & Ecosystem rounds to zero from era 25, Core Development and the Reserve from era 26, and the miner keeps the remainder.
The percentages are hard-coded in the genesis rules. Each allocation is paid automatically to its predefined destination address. Destinations can only be changed through a formal protocol upgrade; the percentages themselves cannot be changed. The three destinations are script addresses held by the project, and they are published together with the genesis rules.
No coins in the genesis block, no hidden treasury — every allocation is visible in every block.
Fixed in the genesis rules for the whole emission schedule. Paid block by block as part of each block reward — not a premine.
| Recipient | Share | Per block (era 0) | Total in era 0 |

| Miner | 80% | 5.00 | 8,399,990 |
| Core Development | 8% | 0.50 | 839,999 |
| Grants & Ecosystem | 4% | 0.25 | 419,999.5 |

| Miners | 16,799,990.4872 |
| Core Development | 1,679,998.7648 |
| Grants & Ecosystem | 839,999.2984 |
| Community & Development Reserve | 1,679,998.7648 |
| Total | 20,999,987.3152 |
Amounts are exact to the smallest unit for the first seven eras (about 28 years). After that the inherited rounding rule rounds each allocation down to a whole unit and the miner receives the remainder, which is why the lifetime miner share is fractionally above 80%.
Genesis rules
These are the addresses the allocations are paid to, and the genesis block they are fixed in. They are part of the network definition every node loads, so a node with different addresses rejects this chain’s blocks and forks itself off. Compare the genesis hash below with what your node reports: if they match, you are on SWARM.
The keys behind the three addresses were generated offline and are held under the custody policy published with the launch manifest in the release repository(opens in a new tab).
Pay-to-script-hash, 2-of-3 multisig (s3…). Each script is controlled by three key shares generated offline at the launch key ceremony and held under the custody policy published with the launch manifest; two of the three are needed to spend.
| Allocation | Share | Destination address |

Checking the chain itself? The public endpoints, the three fund addresses with copy buttons and the address prefixes that tell mainnet from testnet are all on Verify, so they live in one place and cannot drift apart. Check you are on the real chain →
The block reward halves and the 80 / 8 / 4 / 8 split stays exactly the same. The percentages are fixed in the genesis rules and cannot be changed.
Over the whole life of the chain that is 80% to miners, 8% to Core Development, 4% to Grants & Ecosystem and 8% to the Community & Development Reserve.
Paid block by block to its own predefined address, like the other allocations. How it is governed and spent is set out in the custody policy published with the launch manifest.
