There is no foundation or any kind of legal entity running this project. Grin is run by volunteers and is sustained by donations.
The one and only Ignotus Peverell.
We rely solely on donations to keep working on the project. See https://grin.mw/funding
No ICO.
No airdrop.
No premine.
No founder's reward.
Grin is mostly backed by individuals volunteering their time to the project. While companies are more than welcome to provide resources and participate in Grin's development, no single company is meant to influence the decision making process which is based on meritocracy.
No CEO.
On the development side, key contributors to the core project can be found in the Github contribution graph.
UTXO-based model, similar to Bitcoin, with the caveat that there are no addresses supported at the protocol level.
1 minute
Similar to Bitcoin, we use PoW mining and Nakamoto consensus.
Yes, no different to Bitcoin, inherent of PoW mining.
Block time is 1 minute, the main grin wallet waits for 10 block confirmations before it enables reusing a transaction output.
No smart contracts but we can still support some logic on top of simple transaction.
Not at the moment, but we may support Confidential Assets in the future.
Only one.
No bonuses.
- Calculate tx_weight first:
MAX(-1 * (num_inputs + 4 * (num_change_outputs + 1), 1)- (+1 covers a single output on the receiver's side)
- Calculate fee:
tx_weight * 0.001 GRIN
No accounts.
Block Header structure documented here
See Grin Transactions Explained, Step-by-Step and What’s inside a Grin Transaction File?.
Dual PoW based on Cuckoo Cycle. See How to mine Grin and Grin's Proof of Work.

Every six months for the first two years.
The crowdfunding campaign for the security audit is finalized. A company has been found to carry out the audit and they are meant to start on it soon. More details to be added soon. At the same time, Jean-Philippe Aumasson volunteered to do an independent security audit (read his report here).

9 decimals.
1 grin per second forever. Each block contains a 60 grins reward and the block confirmation time is targetted at 1 minute per block.
Ownership and distribution
The total supply is unlimited. See our Monetary Policy on why.
There is no token distribution plan beyond the coinbase reward to the miner that mines a valid block.
We have no projected token price.
We have no market cap projections.
We have no plans to increase the value of the token. We do however make continuous updates to the Grin protocol and the supporting tools and services, which in turn may affect demand.

Wallet Guide: https://github.com/mimblewimble/docs/wiki/wallet-user-guide#listening-via-tor
Tor gives users addresses, which allow support of payment proofs. It is more private and user-friendly to configure than HTTP listeners.
No. Tor is only used for the wallet-to-wallet interaction, not by the node.
No. Extra ports will not be publicly opened.
It sits idle in the background waiting to be used for depositing or withdrawing.
A diverse group of people are involved in Tor, and it is funded and used by governments, universities, and other reputable organizations.
See "Who uses Tor?": https://2019.www.torproject.org/about/torusers.html
