Gridcoin (symbol: GRC) is an open source network protocol using blockchain[1][unreliable source] technology. Like Bitcoin, it is a peer-to-peer cryptocurrency and therefore functions as a form of electronic money.[2][unreliable source][irrelevant citation]

Gridcoin seeks[citation needed] to distinguish itself from Bitcoin by adopting "environmentally friendly" approaches to distributing new coins and securing the network. Most notably, Gridcoin implements a "Proof-of-Research" (POR) scheme, which rewards users with Gridcoin for performing useful scientific computations on the Berkeley Open Infrastructure for Network Computing (BOINC),[3] a well-known distributed computing platform. Gridcoin uses a more energy efficient proof-of-stake system - although it fails to explicitly address the energy cost of computing power.[3]

Main features[edit]

Gridcoin allows near instant peer to peer transactions and worldwide payments at very low processing fees. The code is open source and allows anyone to take part in the success and development of the currency.[citation needed]

Gridcoin features the Proof-of-Research (POR) algorithm, in partnership with Berkeley Open Infrastructure for Network Computing,[4][unreliable source?] commonly known as BOINC. This protocol rewards users of the network once they have completed the computational work unit (WU) in BOINC by linking their Cross-Project ID (CPID) to their Gridcoin cryptocurrency wallet. The reward for computation is a proportional payment of Gridcoin (GRC) based on calculations involving the user's recent average credit (RAC).[5][unreliable source?] Most cryptocurrencies consume a lot of electricity just to secure the blockchain and to achieve consensus on which node will have the privilege to add the next block to the blockchain. Gridcoin consumes most power in calculations that benefit mankind. Only a tiny fraction of the calculations are used to secure the blockchain.[6][unreliable source?]

Gridcoin additionally supports a blockchain-based voting system, which allows users to stay informed and participate in further consensus. One of the main topics voted upon is a whitelist of BOINC projects. This whitelist is kept to ensure that other users don't gain an unfair advantage by maintaining a high RAC, without the ability for anyone to compete. There are also many fun/informal polls created to help users get used to voting and drive up voter participation.[citation needed]


Gridcoin was officially launched October 16, 2013 by its pseudonym developer Rob Halförd.[7][non-primary source needed] Like most cryptocurrencies, Gridcoin works without the intervention of a third party organization.[8][non-primary source needed]

There was a change from the original Gridcoin protocol (Gridcoin-Classic) to Gridcoin-Research, the "actual" Gridcoin on October 11, 2014. Gridcoin-Classic used a hybrid Proof-of-work that allowed for the network to be secured with the help of mining software alongside POS. Comparatively an improvement upon Bitcoin but computational resources were still being wasted. The work users were doing from BOINC were only being used to measure a subsidy distributed through the blocks.[9][non-primary source needed] Gridcoin-Research no longer uses scrypt mining and POW hashing because of how much energy is required to secure the network through these algorithms. With the change to Gridcoin-Research, and the POR algorithm, nearly all of the energy goes to science. The compute power to secure the blockchain is minimal, in-contrast. In the Proof-of-Research algorithm, the BOINC work is not only used to measure the subsidy and provide a unique alternative to classic work measuring Proof-of-Work schemes, but actually complements the security of the Proof-of-Stake system.[citation needed]


Gridcoin attempts to ease the environmental energy impact of cryptocurrency mining through its Proof-of-Research and Proof-of-Stake protocols.[10][11]

Gridcoin reward mechanism[edit]

Gridcoin rewards can consist of 2 parts: Proof-of-Stake and Proof-of-Research.[12][non-primary source needed]

Proof-of-Stake is generating new coins based on an interest rate of 1.5% p.a. on the staking coins. Proof-of-Research adds a payment on top of a minted block reward if a user is participating in BOINC projects that are whitelisted. The number of additional GRC is dependent on the users relative participation within the BOINC network compared to all participants eligible to generate Proof-of-Research.[12][non-primary source needed]
