With support from the global community and open-source contributors, Grin continues to optimize its technology, security, and practical applications.
How Does Grin Work?
No Central Control
Grin operates on a decentralized network of computers (nodes) distributed globally, free from bank or government control.
These nodes collaborate to verify transactions, ensuring system transparency and attack resistance, granting 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, linked through cryptographic hashes to form a secure chain.
Anyone can view the records, establishing trust without intermediaries.
The MimbleWimble protocol enables significant space savings by retaining only transaction kernels of approximately 100 bytes for historical transactions, compared to other blockchains.
Ensuring Fairness
Grin employs Proof of Work (PoW) with Cuckoo Cycle algorithm to validate transactions and prevent fraud such as double-spending.
Miners maintain network security through computational work solving graph-theoretic problems, earning GRIN rewards.
Its innovation includes ASIC-resistant mining design to encourage decentralized participation.
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 while transactions maintain strong privacy through confidential transactions.
Grin employs elliptic curve cryptography, a technology tested over decades, and implements privacy-by-default features making all transactions confidential without optional transparency, providing complete fungibility.
Circulation Overview
As of January 26, 2026, Grin's circulating supply stands at 221,224,920 GRIN, with a total supply of 171,872,000 GRIN. The circulating supply exceeds the total supply due to Grin's inflationary emission model, where new coins are continuously created through mining rewards. New coins enter the market through block rewards distributed to miners using the Cuckoo Cycle proof-of-work algorithm, which influences its supply-demand dynamics. Grin follows a community-driven distribution approach with no pre-mine or initial coin offering, ensuring all coins are mined and distributed fairly over time.
Price Volatility
Grin reached its all-time high price of $25.09 on January 17, 2019, driven by strong market interest following its launch and the novelty of its MimbleWimble privacy protocol implementation. Its lowest price of $0.01332513 occurred on April 7, 2025, reflecting broader market corrections and reduced trading activity. These fluctuations demonstrate the impact of market sentiment, adoption trends, technological developments, and external market conditions on the asset's valuation.
