GRIN is a new cryptocurrency focused on privacy and scalability. It uses the MimbleWimble protocol to encrypt transactions and make them untraceable, addressing issues of privacy and data collection. GRIN launched its testnet in late 2018 and is expected to fully launch in 2019. It uses a Cuckoo Cycle proof-of-work algorithm to achieve consensus in a decentralized manner and resistant to ASIC miners. GRIN's monetary policy aims to make its value more stable over time to function better as a currency rather than a store of value.

1. Facts About New Cryptocurrency
Coin

2. Introduction
● The constant digitization has its allure but in doing so
there is a decrease in privacy.
● For companies like Facebook & Google , the personal
data of a person seems to be fair game for all.
● Last month, a new blockchain, focused on privacy and
GRIN was launched.
● This new crypto uses its native MimbleWimble protocol to
transact in Bitcoin.

3. What is GRIN?
● GRIN is an upcoming cryptocurrency project focused on
scalability and privacy that is built by implementing a
MimbleWimble blockchain.
● It is an open-source project that offers a refreshing list of
things that it will not do.
● This name borrowed from the famous children’s fantasy
universe of Harry Potter.

4. Continued
● MimbleWimble was a promising crypto protocol that
encrypts multiple transactions to make them inaccessible
to anyone.
● This was designed by a coder who goes by the moniker,
Tom Elvis Jedusor and then this code was used by a
cryptographer.
● He worked on and implemented the protocol to release a
token named as GRIN.

5. What is MimbleWimble?
● It is a blockchain protocol that mixes several innovative
technologies to radically change how transactions are
constructed in Bitcoin.
● It also reduce the size of the blockchain.
● It addresses two areas that is privacy and scalability.

6. How Does Grin Work?
● Most cryptos work on a principle of full transparency but
Grin being a privacy looks to do the exact opposite.
● It ensure that transactions on their chain are anonymous,
non-transparent and untraceable.
● Its Peer to Peer setup allows wallets to trade.
● It ensure that wallets that are executing the trade only
those exchange data for a limited time.

7. Grin’s Cuckoo Proof-of-Work Consensus
● Grin does not implement a new consensus mechanism
like proof of stake to achieve consensus.
● It goes back to the bread and butter of PoW using the
Cuckoo Cycle algorithm.
● PoW was selected to mitigate against the Bitcoin-style
“hardware arms-race” by making it ASIC resistant.
● Cuckoo Cycle is a memory-bound algorithm, making it
viable for CPUs and increasing its decentralization.

8. Monetary Policy of Grin
● Grin aims to be more of a currency for transacting than a
store of value, currently different from Bitcoin.
● It has created a monetary possible that is designed to
make the currency’s value more stable.
● Myles Snider offers an excellent analysis of the potential
implications of Grin’s monetary policy.

9. Current Status of Project
● Grin released its Testnet V4 and the cryptocurrency is
expected to launch sometime in 2019.
● Grin has flown under the radar compared to more high-
profile projects.
● Grin’s use of the MimbleWimble protocol gives it some
compelling potential.
● Grin is open to contributions from developers and is
definitely worth watching as it continues to evolve.
