What is Goldcoin
Goldcoin (GLC) is an open-source cash payment cryptocurrency on its own proof-of-work chain, launched in May 2013 as a fork of Feathercoin. Since 2026 GLC also exists as a token on Solana and Robinhood Chain.
Network and consensus
| Parameter | Details |
|---|---|
| Type | Layer 1 proof-of-work chain; also a token on Solana and Robinhood Chain. |
| Consensus | Proof of work with the Scrypt algorithm. |
| Launched | 14 May 2013 on the bitcointalk.org forum; originally forked from Feathercoin. |
| Block time | 2-minute block target (2.5 minutes up to block 44,999); difficulty retargets every block. |
| Capacity | 32 MB blocks; the project states 1,120 transactions per second. |
| Fees | Transactions are free by default; a small fee buys miner priority under heavy traffic. |
| Attack protection | The chain uses its own 'Golden River' difficulty algorithm and a dual 51% defense system. |
Supply and issuance
| Parameter | Details |
|---|---|
| Maximum supply | 1,172,245,700 GLC total coins. |
| Issuance | Block reward of 3 GLC from block 1,468,200, then reduced each year by a formula; block rewards end in 2100. |
| Treasury | In August 2026 one billion GLC was locked on-chain in two hundred 5-million-GLC tranches. |
| Treasury release | The locked treasury is released on a fixed annual schedule enforced by consensus. |

History
| Date | Event |
|---|---|
| 14 May 2013 | Goldcoin launched on the bitcointalk.org forum, originally forked from Feathercoin. |

Security and audits
- The chain uses a dual 51% defense system and automated checkpointing; the v0.17.0 client rewrote the 51% defense system.
- The v0.17.0-beta1 release notes say it fixes a critical consensus bug and a wallet-corruption risk on Windows.

Native GLC runs on its own chain. The home page also lists a Robinhood Chain GLC token and a separate community memecoin on Solana, which is not GLC.
Risks and caveats
- Official supply and treasury numbers differ between pages (fixed 1,172,245,700 GLC vs. 'Total Blocks: Infinite'; 1.1 billion vs. one billion GLC treasury).
- The project plans an AI engine that trades at high frequency to align GLC prices across chains.
- The README says AI agents perform most of the development work.
