Groestlcoin Core is a full Groestlcoin client and builds the backbone of the network. It offers high levels of security, privacy, and stability. However, it has fewer features and it takes a lot of space and memory.
Groestlcoin Core is programmed to decide which block chain contains valid transactions. The users of Groestlcoin Core only accept transactions for that block chain, making it the Groestlcoin block chain that everyone else wants to use.
It is these users who keep Groestlcoin decentralized. They individually run their own Groestlcoin Core full nodes, and each of those full nodes separately follows the exact same rules to decide which block chain is valid.
There’s no voting or other corruptible process involved: there’s just individual software following identical rules—”math”—to evaluate identical blocks and coming to identical conclusions about which block chain is valid.
This shared agreement (called consensus) allows people like you to only accept valid groestlcoins, enforcing Groestlcoin’s rules against even the most powerful miners.
In addition to improving Groestlcoin’s decentralization, Groestlcoin Core users get better security for their groestlcoins, privacy features not available in other wallets, a choice of user interfaces and several other powerful features.
