NEWS & Developments

Grinventions:

First Python-based implementation of the Mimblewimble protocol for the Grin ツ cryptocurrency is being built by developer @renzokuken. It will be heavily based on GRIN++. The development has just started, it is at early stages, but use cases will be:
- Implementation of python-based wallets and nodes for Grin.
- Research of new protocols, quickly drafting ideas and testing them.
- A Grin codebase that anyone can easily understand and translate to other languages.

Coinswap:

‘‘Trustless’’ Mimblewimble CoinSwap implementation milestone 2 achieved by scilio! Review, testing and discussions are being made and final phase-Milestone 3 will begin shortly. When CoinSwap is implemented, GRIN ツ will gain more privacy and fungibility.

‘‘Widespread use of the protocol would leave the transaction graph mostly obscured’’

J.Tromp.
