Grin (GRIN) Price

Grin is a proof-of-work blockchain based on Mimblewimble that aims to serve as privacy-oriented digital cash for electronic transfers; its native asset is GRIN. The network is developed openly by distributed contributors and is not operated by a company or foundation. GRIN is used on the network for value transfers and to pay transaction fees. Grin's design places privacy, scalability, and a relatively concise protocol implementation at its core: it does not organize transactions around the conventional display of on-chain account balances and public receiving addresses.

Grin transactions do not directly disclose amounts and conventional on-chain addresses by default; Mimblewimble uses cryptographic commitments to validate transactions while preventing amounts from appearing in plaintext on the ledger. Transactions can also be aggregated, and historical data from spent transactions can be pruned. These two aspects serve different purposes: concealing amounts and not using the conventional display of on-chain addresses change what can be directly observed from the ledger; aggregation and pruning reduce the historical transaction data that must be retained long term to validate the current state. Therefore, Grin's privacy design affects both ledger visibility and the amount of data nodes need to store.

Sending GRIN usually requires the sender and recipient to complete a transaction together, rather than the sender unilaterally broadcasting a transfer to a permanent on-chain receiving address. This is because both parties must add the necessary data and signatures to an unfinished transaction data structure (slate) before it can be placed on-chain. The standard process is: the recipient first provides a Slatepack address; the sender creates a slate, encrypts it with that public key, and sends it; the recipient adds their own data and partial signature and returns it; the sender completes their partial signature and the final data, then broadcasts the transaction. This Slatepack address is used for peer-to-peer interaction and is not a conventional receiving address on the ledger. By default, wallets attempt to communicate automatically with the recipient's wallet via Tor. If the connection fails, the parties can manually exchange encrypted Slatepack text; only after the round trip is complete and a full signature is formed can the sender submit the transaction. Therefore, an unfinished interaction and a transaction submitted on-chain are different stages.

GRIN has no fixed maximum supply. Under the protocol rules, new issuance is added permanently at a constant rate of 1 GRIN per second, so supply grows linearly over time rather than reducing the absolute amount of new issuance in stages as in a halving-based model. If t denotes the seconds elapsed since a supply reference point, new issuance is t GRIN, and total supply can be written as S(t)=S(0)+t. Here, S(0) is the supply at that reference point; using a 365-day calculation basis, one year corresponds to 31,536,000 seconds, so the rule corresponds to approximately 31,536,000 newly issued GRIN. This example describes the protocol issuance rate, not a price prediction. The absolute amount of new issuance remains unchanged, but as the existing supply S(t) grows, the same new issuance represents a smaller proportion of total supply. Therefore, Grin's inflation rate declines over time, while total supply continues to increase.

Grin had no ICO, premine, founder reward, or developer tax. Its new GRIN enters the network through ongoing block subsidies, rather than being concentrated at launch among a predesignated group. Miners in the proof-of-work network receive block rewards for producing blocks; the reward consists of newly issued block subsidies and transaction fees paid by users. A constant block subsidy means that even when blocks are not congested or fees paid by users are low, miner incentives do not depend entirely on transaction fees. Therefore, linear issuance connects both distribution and security: new participants can participate in new issuance through mining at any point in time, while ongoing subsidies continue to provide a source of network security expenditure. It does not mean every holder receives new coins; holders face rules under which total supply continues to grow and the proportion represented by new issuance gradually declines.
