# Curecoin (CURE): how it works, supply and reviews

## In short

- **Type**: Own blockchain combining proof of stake with rewards for Folding@home computation.
- **Issuance**: Folders as a whole receive 3,744 CURE per day, shared by their share of team points (schedule as of the May 2018 halving).
- **Risks and caveats**: Folding rewards depend on the project's folding pool rather than on-chain rules; moving them into the wallet is still a goal.
- **Checked**: 1 November 2026

## What is Curecoin

Curecoin (CURE) is a cryptocurrency created in 2014 to support medical research. Participants earn coins for running Folding@home protein-folding simulations, and since a 2018 hard fork the chain is secured by proof of stake instead of ASIC mining.

## Network and consensus

| Parameter | Details |
|---|---|
| Type | Own blockchain combining proof of stake with rewards for Folding@home computation. |
| Consensus | Pure proof of stake since the 2.0 hard fork; SHA-256 ASIC mining was removed. |
| Block time | 4-minute blocks since the 2.0 hard fork (previously 10 minutes). |
| Staking | Coins start staking after 4 days of coin age (previously 30 days). |
| Launched | Curecoin launched in May 2014; Curecoin's own posts give 10 May (2022 post) and imply 5 May (2024 post calls 5 May its 10th anniversary). |
| Chain status | Block 1,273,847 was produced at 02:41 UTC on 1 November 2026 (proof of stake). |
| Wallet software | Latest wallet release, v2.5.2.2, was published on 9 June 2026. |

## Supply and issuance

| Parameter | Details |
|---|---|
| Issuance | Folders as a whole receive 3,744 CURE per day, shared by their share of team points (schedule as of the May 2018 halving). |
| Initial distribution | 4% of the total distribution is reserved for blockchain maintenance over a 100-year mintage; 2% went to the 2014 crowdfund donors. |
| Team allocation | 213 CURE a day are set aside for management, promotion and development costs. |
| Staking rewards | Minimum staking reward raised to 4% from 1% at the 2.0 hard fork. |
| Halving | The halving due on 10 May 2022 was deferred; a 25% reduction was announced for 5 May 2024. |

## What CURE is used for

- CURE is earned by contributing computing power to Folding@home protein-folding research.
- Holders can stake CURE in an unlocked wallet to mint proof-of-stake blocks.
- CURE can be donated to medical research organisations or exchanged for other currencies.

## Who develops and governs Curecoin

- **Company**: CureCoin LLC and The CureCoin Project hold accumulated tokens to fund development (2017 statement).
- **Non-profit arm**: The CureCoin Project has fiscal sponsorship from Visions Made Viable, a 501(c)(3) non-profit in California (2016).
- **Research partner**: The Curecoin folding team contributes to the Folding@home project at WUSTL (formerly Stanford).
- **Open source**: Wallet code is on GitHub (cygnusxi/CurecoinSource); a 10,000 CURE bounty was offered for a walletnotify feature.
- **Rewards distribution**: Folding rewards are paid through the project's folding pool; moving them into the wallet client is a roadmap goal.

## History

| Date | Event |
|---|---|
| May 2014 | Curecoin launches, paying 7,488 CURE a day to protein folders. |
| 8 May 2017 | The team publishes its letter to Poloniex responding to the exchange's delisting of CURE. |
| 22 December 2018 | Hard fork to Curecoin 2.0 (release 2.0.0.1) removes ASIC proof-of-work mining. |
| 10 May 2022 | The team defers the halving scheduled for 10 May 2022. |
| 9 February 2024 | Curecoin announces a 25% reward reduction ('soft halving') for its 10th anniversary on 5 May 2024. |
| 9 April 2025 | The team starts testing its own distributed computing framework, first for prime-number research. |
| 9 June 2026 | Wallet v2.5.2.2 adds an unlock-for-staking-only option. |

## Security and audits

- The project argues proof of stake resists 51% attacks because an attacker would need to hold 51% of all CURE.
- The knowledge base advises always encrypting the wallet; v2.5.2.2 can unlock a wallet for staking only.
- A code bounty of 10,000 CURE was offered for a wallet feature, claimed through a GitHub pull request.

## Security incidents

No security incident is recorded in the sources checked on 1 November 2026 (the company’s own channels and incident databases): [defillama.com/hacks](https://defillama.com/hacks), [hacked.slowmist.io/search](https://hacked.slowmist.io/search/), [rekt.news/leaderboard](https://rekt.news/leaderboard/), [curecoin.net](https://curecoin.net/dev-blog/), [github.com/cygnusxi/CurecoinSource/releases](https://github.com/cygnusxi/CurecoinSource/releases)

## Risks and caveats

- Folding rewards depend on the project's folding pool rather than on-chain rules; moving them into the wallet is still a goal.
- The team sets aside 213 CURE a day for its own costs, outside the public distribution.
- The reward schedule has been changed by team decision (halving deferred in 2022, 25% reduction announced for 2024).
- The project's own supply figures are not kept up to date (27.8 million on a page last modified in 2023).
