## What is Novacoin

Novacoin (NVC) is a cryptocurrency launched in early 2013 that combines scrypt proof-of-work and proof-of-stake block generation with separate difficulty targets. It has no fixed maximum supply; block rewards fall as difficulty rises.

## Network and consensus

| Parameter | Details |
|---|---|
| Type | Layer 1 blockchain with its own chain (Bitcoin/Peercoin-style codebase) |
| Consensus | Hybrid proof-of-work (scrypt) and proof-of-stake with separate target limits |
| Block time | 10 minutes between stake blocks, 30 minutes between PoW blocks |
| Confirmations | 6 confirmations for transactions, 520 for mined blocks |
| Stake age | Coins start staking after 30 days and reach full weight at 90 days (source code) |
| Chain activity | The official explorer listed block 1,108,140 among the latest blocks on 31 October 2026 |

## Supply and issuance

| Parameter | Details |
|---|---|
| Maximum supply | No fixed maximum supply |
| Issuance | Maximum PoW reward 100 NVC per block; maximum PoS reward 10 coins |
| Halving | PoW reward halves with every 64x rise in PoW difficulty; PoS interest halves with every 8x rise in PoS difficulty |

## What NVC is used for

- NVC is the native coin used to pay transaction fees (0.001 NVC per kB).
- Holders can stake NVC to create proof-of-stake blocks and earn stake rewards.

## Who develops and governs Novacoin

- **Founders**: Introduced in early 2013 by a team led by a developer known as Balthazar
- **Governance**: Changes are merged through pull requests when there is broad consensus among developers
- **Open source**: Source code on GitHub (novacoin-project/novacoin), still updated in 2026

## History

| Date | Event |
|---|---|
| 2013 | Novacoin is introduced by a development team led by Balthazar. |
| 20 July 2013 | PoW block spacing on mainnet is set to 30 minutes from this date (source-code comment). |
| 4 April 2016 | Release 0.5.8 is tagged. |
| 11 February 2022 | Release 0.5.10, the latest tagged release, is published. |
| 22 September 2026 | Code for validating post-quantum signatures is added to the main branch. |

## Security and audits

- Blocks from proof-of-work need 520 confirmations before they mature; transactions are considered final after 6 confirmations.
- In September 2026 developers added validation for post-quantum signatures to the main branch (not yet in a tagged release).

## How voting works

Votes are anonymous and carry no text. Each device has one vote per item; press the same button again to remove it. Cloudflare Turnstile checks that a person is voting. We keep a random device ID in a cookie and a salted hash of the IP address to limit abuse — no names, no accounts. Votes are visitors’ opinions, not investment advice.
