[ANN] Blacknet BLN | Staking | Future of zApp & ZeFi

[Buchi-88]

Good news, everyone!

After seeing in news that some crypto dev went hunting for aliens, I thought this is the time to start incorporating the time traveling into the research. And here is the first result: in future we'll target a stable supply as opposed to the currently inflationary one. I already feel overwhelmed with the tasks that were picked for the next upgrade, so this is probably a material for PoSv6.

Thanks for an update even though it's been a while, what's the current status, will there also be a slightly bigger exchange in the future like MECX or also a smaller one like FreiExchange?

What exactly do you mean by PoSv6? How will staking with a fixed supply take place in the future?

6 is just a number after 5, there's no meaning at this point. For the next upgrade, which is fifth, I'm looking for, but not guarantee the delivery of, following:
- Privacy of stakers. It was requested even in 2014... Time has come.
- Unpredictability of stakes. Staking starts after a few minutes rather than multiple hours.
- Succinct proof. A move towards fast sync and cross-chain stuff.

The idea of stable (not fixed!) supply is to reward stakers with tx fees averagely, but mint or burn under certain conditions until normality is restored.

You can fill out this form?


Are there any further updates, I have seen that the wallet has been updated to Version 0.2.14.

I am still using 0.2.13 on my Raspberry, is the update mandatory?

Are there any other updates, and how far are you in your list of to do's?

A listing on the Coingecko site might also be helpful?

[rat4]

Not sure if my message should start with squeak that MEXC blocks Tor. Bzuhzzzzzzzuhzzzzzuhzzzz. Maybe you can?

Version 0.2.14 fixes a few glitches in wallet and enhances I2P support. I'll see how to make the website more clear respectively such questions.

Got to learn the power of ZK. For example, dark pool is sorta opposite problem: ZK is about our own secrets, but there the secret is what others wanna buy/sell. Nevertheless, ZK-PCD is the piece of puzzle that I was missing.

Right now my goal is to learn about lattice-based cryptography. Probably it's more known from the topic of quantum-resistance, but recent publications indicate we may be interested because of other reasons. And if it plays out, quantum-resistance is a nice bonus on top of that.

I'm not the owner so i don't know all the details for the exchange request form. Also a Coingecko listings helps i think.

I already installed the new version on my Raspberry, I already tried to run my Raspberry as full node, port forwarding actvated but I don't find my full node, do I need more details in my config file?

I don't target everything, certainly not something like this

Not sure if you don't see incoming p2p connections, can't access UI/RPC from other computer, or the actual situatuon is https://www.youtube.com/watch?v=gQgh69lpnjU

I recommend at least version 0.2.11 released in 2021. In fact, some older versions are compatible with current network too, but can work not so stable in practice. Also it's the minimum version that can work with current Tor network.

This info is on download and anonymity pages.

Report on progress in... paper format
It's about how we can leverage homomorphic encryption for privacy of lightweight wallets, or rather a quite specific question that arises somewhere there.
Probably, we'd want to encode a zero-knowledge proof alongside public key in an address, but so far post-quantum proofs look too large for this. I made up following as a possible alternative:
BlackLemon: Snake-eye Resistance with Short Secrets
It restricts lightweight wallets to a single receive address, however almost doesn't touch anything else.

XeggeX exchange is restoring after an incident. If you use their services, check out the details: https://xeggex.com/incident

After longer time i will start my blcknet wallet on my Raspberry but i get this error massage?

Any idea? My Raspberry is up to date und java is installed.

I hope you can help me to start my blacknet node again.

I think I have found the error, the USB stick has jumped to read only mode, probably due to the many write accesses, because I have saved the blockchain on the stick.

I have currently deactivated my Raspberry, will get a new USB stick and copy the old data and then restart the node.

Let me know when everything is working again, for a full node, which port do I need to open at my router?

Let me know when everything is working again, for a full node, which port do I need to open at my router?

In default configuration file, port=28453 and upnp=true
You can change these as needed, if the node doesn't automatically show up in a router interface. If UPnP is enabled, its status will also be in the node logs.
