在 巴西 購買 Grin (GRIN)

Grin is an open-source, community-driven cryptocurrency project that focuses on privacy, scalability, and fungibility. Launched in January 2019, it is an implementation of the Mimblewimble protocol, which was originally proposed anonymously in 2016. The project is named after Gringotts Wizarding Bank from the Harry Potter series, and many of its early developers used pseudonyms from the same universe. The primary technological foundation of Grin is the Mimblewimble protocol. This protocol allows for a blockchain that does not store the entire history of every transaction. Instead, it uses a process called cut-through to remove spent transaction data, which keeps the blockchain lightweight and scalable. In terms of privacy, Grin does not use traditional public addresses or show transaction amounts on the public ledger. Instead, transactions are constructed through a direct interaction between the sender and the receiver, using blinding factors and cryptographic proofs to verify that coins are not created out of thin air while keeping the participants and values hidden. Grin uses a proof-of-work consensus mechanism to secure its network. Its algorithm, known as Cuckoo Cycle, was designed to be memory-intensive. The project initially launched with two versions of this algorithm to balance accessibility for general-purpose hardware like GPUs while acknowledging the eventual emergence of specialized mining hardware. The project is notable for its commitment to a fair launch. There was no initial coin offering, no pre-mine, and no founder rewards or developer taxes. The development is funded entirely by community donations and supported by a global network of volunteers. Governance is decentralized, with decisions made through open, bi-weekly public meetings and a request-for-comments process rather than a central corporate entity or foundation. Grin features a linear emission model where new tokens are created at a constant rate for perpetuity. This design choice is intended to encourage the use of the token as a medium of exchange rather than a speculative store of value, as there is no cap on the total supply and the relative inflation rate decreases over time. The project is written in the Rust programming language, chosen for its speed and security characteristics. Overall, Grin represents a minimalist approach to digital cash, prioritizing technical elegance and user privacy. 瞭解更多
