A Gridcoin-Research block encapsulates a header and body. While Bitcoin’s transaction data structure and concept is used in an unmodified version, Gridcoin-Research utilizes a slightly modified block structure.

Īs a fork of Litecoin, Gridcoin-Research is a blockchain based cryptocurrency and shares many concepts with Bitcoin. It is recalculated whenever a host generates credit. If an entire week passes, the value is divided by two.

RAC is defined as the average number of Cobblestones per day generated recently.

Total number of Cubblestones a user invested with his machines for scientific computations.

They are measured in Cobblestone, whereas one Cobblestone is equivalent to 1/200 of CPU time on a reference machine with 1,000 mega floating point operation per seconds

BOINC credits are generated whenever a host submits a solution to an assigned task.

It is computed by applying the cryptographic hash function MD5 to (iCPID,email) and thus has a length of 16 byte.

The external Cross Project Identifier (eCPID) serves the purpose of identifying a volunteer across different BOINC projects without revealing the corresponding email address.

From this time on, the iCPID is included in every request and response between client and server This value is stored by the client and server.

The BOINC project server creates the internal Cross Project Identifier (iCPID) as a 16 byte long random value during account creation.

This application consists of one or multiple in-/output files, containing binary or ASCII encoded parameters. All workunits are created by the server component and each workunit represents a chunk of a scientific problem which is encapsulated into an application. The solutions are validated and assimilated by the server component. The server component handles the client requests for workunits and the problem solutions uploaded by the clients. The volunteers can process the project tasks and transfer their solutions with a BOINC client.īOINC uses a client-server architecture to achieve its rich feature set.

Project volunteers may then create accounts (by submitting a username, a password and an email address) and work on specific project tasks, called workunits. When launching a BOINC project, its maintainer is required to set up his own BOINC server.

Nowadays it is widely used by researchers with limited resources to solve scientific problems, for example, healing cancer, investigate global warming, finding extraterrestrial intelligence in radio signals and finding larger prime numbers. The platform enables professionals in need for computation power to distribute their tasks to volunteers.

It is a software platform for volunteer computing, initially released in 2002 and developed by the University of California, Berkeley. To solve general scientific meaningful problems, Gridcoin draws on the well-known Berkeley Open Infrastructure for Network Computing (BOINC). Berkeley Open Infrastructure for Network Computing
