How Does Grin Work?
Decentralized Control
Grin operates on a decentralized network of computers (nodes) spread across the globe, free from control by banks or governments.
These nodes collaborate to verify transactions, ensuring system transparency and attack resistance, giving users greater autonomy and enhancing network resilience.
Blockchain Core
Grin's blockchain is a public, immutable digital ledger that records every transaction.
Transactions are grouped into blocks and linked through cryptographic hashes to form a secure chain.
Anyone can view the records, establishing trust without intermediaries.
Grin's implementation of the MimbleWimble protocol enhances privacy and scalability.
Ensuring Fairness
Grin uses a Proof-of-Work (PoW) consensus mechanism to validate transactions and prevent fraudulent activities such as double-spending.
Miners maintain network security through computing power and receive Grin rewards.
Its innovation includes ASIC-resistant mining algorithm (Cuckoo Cycle) to encourage decentralized mining.
Secure Transactions
Grin uses public-private key cryptography to protect transactions:
- Private keys (like secret passwords) are used to sign transactions
- Public keys (like account numbers) are used to verify ownership
This mechanism ensures fund security, keeping transactions private.
Grin also implements additional privacy features through the MimbleWimble protocol, such as confidential transactions and transaction aggregation.
Circulation Overview
As of November 21, 2025, GRIN's circulating supply is 215,514,540 coins, with a total supply of 171,872,000.
New coins enter the market through mining, influencing its supply and demand dynamics.
Price Fluctuations
GRIN reached its all-time high of $25.09 on January 17, 2019.
Its lowest price was $0.01332513, occurring on April 7, 2025.
These fluctuations reflect market sentiment, adoption trends, and external factors.
