[Discussion] Consider removing the tx_extra field

54

First discussed here: https://github.com/monero-project/meta/issues/356 We should consider removing the tx_extra field from all non-coinbase transactions. Main reasons: 1. Enhanced fungibility due to a more uniform transaction format. 2. Protection from...

Hash functions with expensive seeding are not handled optimally

4

I'm testing a custom hash function with very expensive seeding (100 000 cycles to change the seed). Once seeded, the hash function is very fast (~270 cycles/hash). SMHasher is changing...

Dummy transaction inputs

15

This is not a fully thought out proposal, just an idea I had today. It's an extension of the [idea](https://github.com/monero-project/research-lab/issues/95#issuecomment-1004985047) by @paulshapiro to mandate all transactions to have 16 outputs....

Mining protocol changes to combat pool centralization

19

Monero mining has been [centralized to 2-3 large pools](https://miningpoolstats.stream/monero) for a long time (recently, the largest pool even briefly exceeded 50% of the hashrate). This unhealthy situation is not going...

Radical idea for forward secrecy and instant wallet sync

13

Since [Jamtis has been modified](https://gist.github.com/tevador/50160d160d24cfc6c52ae02eb3d17024#gistcomment-4293118) to allow Seraphis membership proofs to have perfect forward secrecy, the Diffie-Hellman key exchange will become the weakest point of Monero with respect to forward...

Consider Switch commitments for future supply security

29

Monero currently uses Pedersen commitments to hide real transaction amounts. The commitments have the form of `C = r*G + v*H`, where `r` is the blinding factor, `v` the amount...

The cryptographic primitives used by "derohe" are not documented, but based on the [source code](https://github.com/deroproject/derohe/blob/main/cryptography/bn256/constants.go), the implementation seems to be using a pairing-friendly Barreto-Naehrig-type elliptic curve with a field size...

Daemon RPC: add a new method to get height from a timestamp

5

This is for wallets that need to convert a user-provided date to a blockchain height. Similar function is currently implemented in wallet2::get_blockchain_height_by_date, but it's done quite inefficiently by pulling whole...
