Q: What practical purpose does Grin's privacy design serve?

Grin transactions do not directly show amounts and common recipient addresses on-chain as many blockchains do. Mimblewimble hides amounts with cryptographic commitments and can aggregate transactions and remove spent intermediate data, improving privacy and reducing long-term chain data.

Q: Why do both parties need to interact when sending GRIN?

A Grin payment requires the sender and recipient to exchange transaction data to jointly complete and sign it. Wallets first try to communicate through Tor; if that is not possible, they can exchange Slatepack, an encrypted text message carrying transaction data.

Q: Is GRIN's supply capped?

GRIN is issued linearly at a fixed rate of one new coin per second, continuously, so there is no fixed maximum supply. As circulating supply grows, new issuance becomes a smaller proportion of existing supply, while total supply continues to increase.

Q: How is GRIN issued and distributed?

Grin has no ICO, premine, founder rewards, or development tax. New coins enter circulation through block subsidies, and miners also receive transaction fees; these continuing block subsidies maintain mining incentives for the proof-of-work network.

Q: What does ongoing issuance mean for GRIN users?

GRIN's block reward consists of newly issued block subsidies and transaction fees paid by users. Continuing subsidies reduce pressure for the network to rely only on transaction fees to incentivize miners, but holders should also understand that linear issuance increases total supply over time.

Why Did Grin (GRIN) Rise in the Last 24 Hours?

At 09:00 UTC on 2026-10-21, the bid-to-ask depth ratio across the top five levels was 0.28, with total asks about 3.5 times the bids. An 8,080-GRIN sell order was concentrated at $0.012, while bids were more concentrated at $0.01156. A shallow, imbalanced order book means that limited trading can cause more noticeable price moves, but posted orders do not represent completed trades. The single candle at that time had volume of about 30,000 GRIN and closed down 0.18%; its estimated turnover was about $330 at the price then. Technical signals were bearish overall: moving averages were bearish on the 1-hour and daily timeframes, and MACD showed no crossovers on any timeframe. The elevated 15-minute ADX indicated a strong trend, but RSI and MACD did not confirm its direction. Low liquidity can amplify short-term fluctuations, while the available indicators did not jointly confirm a clear direction.

About Grin (GRIN)

Grin is an open source software project to implement the mimblewimble blockchain, and fills in some necessary things (missing in the mimblewimble protocol) to implement a complete blockchain and cryptocurrency. The main purposes and features of the grin project are as follows: the default feature of privacy protection. This makes it completely replaceable and retains the ability to selectively disclose information on demand. The block size matches the transaction volume. Only about 100 bytes of transaction kernel is reserved for historical transactions, which saves a lot of space compared with other block links. Powerful and proven cryptography. Mimblewimble only uses elliptic curve cryptography, which has been tried and tested for decades. Simple design makes it easy to review and maintain the code in the future. Community driven. A mining algorithm that resists ASIC (cuckoo cycle algorithm) is adopted to encourage decentralized mining.

Use Cases and Features

Grin is a privacy-focused digital cash network based on Mimblewimble. GRIN is used for on-chain transfers and to pay transaction fees. Transaction amounts and conventional on-chain addresses are not directly disclosed; transactions can also be aggregated in blocks and spent intermediate data removed, balancing privacy with blockchain data size. Senders and receivers must exchange transaction data to complete a payment together. Wallets usually communicate through Tor and can also use Slatepack encrypted text messages.

Supply and Issuance Mechanism

GRIN has linear issuance: one new coin is issued per second, and issuance continues with no premine, ICO, founder rewards, or development tax. Block rewards include newly issued block subsidies and transaction fees; the ongoing subsidy is intended to provide long-term mining incentives for the proof-of-work network. As a result, total supply increases over time, while new supply gradually becomes a smaller proportion of the existing supply.
