Goldcoin (GLC) is a peer-to-peer cryptocurrency that strives to provide a digital alternative to traditional cash payment systems. Launched in 2013, Goldcoin is an open-source platform that operates without a central authority, with transactions and coin issuance managed collectively by the network. Goldcoin's blockchain operates on a proof of work (POW) algorithm, similar to other well-known cryptocurrencies. The platform is designed to scale on-chain, eliminating the need for Layer 2 solutions, and enables instant payments to anyone, anywhere in the world, with or without additional charges.

Goldcoin operates on a proof of work (POW) algorithm, with features such as 2-minute block intervals, 32 MB block size, full 0-Conf support, on-chain scaling, and a 51% Defense System. This system is designed to protect the network from potential attacks and harsh mining environments. Goldcoin's network capacity is 1,120 transactions per second, and it supports transactions without additional charges. The platform's design allows for instant transactions, making it a convenient option for users who require quick and efficient digital transactions.

Goldcoin strives to serve as a secure value store and cash payment system. It is designed to be used by anyone, anywhere in the world, offering a global reach that traditional banking systems may not provide. Goldcoin can be stored on a desktop wallet, Android device, or paper wallet, offering flexibility in how users choose to manage their assets. The platform's high transaction capacity and support for transactions without additional charges make it a potentially attractive option for high-volume, low-cost transactions.

Goldcoin was launched on May 15, 2013, initially forked from Feathercoin. Since its inception, the platform has undergone several transformations, with the current client software being SegWit free, RBF free, and utilizing its own proprietary difficulty adjustment algorithm called Golden River. In September 2023, a block containing 1,100M coins was created with a funding target of 110 years, which intended to provide long-term funding for the project. The platform's development is managed by an international community of contributors who are dedicated to the mission of providing economic freedom to all people.
