Bevy + egui in a text-based, turn-based adventure game.

Bevy + egui in a text-based, turn-based adventure game.

I won't go too far into the nitty details (lol), but this is generally how I've structured my WIP mostly-text-based, turn-based adventure game. I emphasize that because I suspect this approach doesn't work all that well for other styles of games. Specifically, because practically everything in my game happens on-click; there's very little running in the background.


Nah, I strained my eyes for this.

Monero checksum search

1. Introduction

This document describes the search for a checksum algorithm to be used with Monero's new addressing scheme Jamtis. The purpose of the checksum is to detect accidental corruption of the address string.

Since Jamtis encodes addresses in base32, it allows the use of cyclic codes, which can provide guaranteed error detection, unlike hash-based checksums.

1.1 State of the art

Monero currently uses a 32-bit hash-based checksum for its addresses. Hash-based checksums have a flat false positive rate regardless of the number of errors. Bitcoin's bech32 address format uses a degree-6 cyclic code optimized for short addresses of up to 89 characters. The cashaddr address format of Bitcoin Cash uses a degree-8 cyclic code that can detect 5 errors for lengths of up to 130 characters.

[Draft] Zero-cost post-quantum mitigations for Seraphis

This draft presents post-quantum mitigations for Monero's next transaction protocol Seraphis. These mitigations are "zero-cost" in the sense that they only involve changes to the way private keys and blinding factors are calculated, which is transparent to blockchain verifiers. Mitigated keys will be compatible with a future hard-fork that can be put in place to ensure monetary soundness and security of the protocol even against a quantum computer.

While these mitigations do not prevent a quantum adversary from breaking the privacy of past transactions, they protect Monero from a total collapse that would result from an undetectable money supply inflation or the theft of users' funds.

1. Introduction

In 2020, Monero performed a post-quantum security audit that confirmed severe vulnerabilities of the transaction protocol against quantum algorithms [[1](


This document describes a new addressing scheme for Monero.

Chapters 1-2 are intended for general audience.

Chapters 3-7 contain technical specifications.

Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare
