Coin launch / structure

Where's the whitepaper?

A paper describing the intention for Ravencoin is available on the Ravencoin.org site here other papers are also linked here

What's the roadmap for Ravencoin?

https://github.com/RavenProject/Ravencoin/blob/master/roadmap/README.md

All papers are linked to from https://ravencoin.org/whitepaper/. The Development section also summarizes all roadmap phases.

Any ICO/Premine/Masternodes?

No. Ravencoin had a fair launch, open source project focused on building good code with a good use-case. It was announced on twitter and discussed at several meetups months prior to launch. There's a timeline of some of these events here

Further points about the launch where made on Telegram on the 6th May 2018

The devs should do <insert topic here> / Why aren't the devs doing <insert topic here>?

This is an open source project. You can do whatever you want with it. The devs are focused on the code development inline with the roadmap. Members of the community can build tools and websites around the coin that they think could be useful.

What's the max supply?

21 billion

What's the halving rate?

The same as bitcoin so every 4 years or so. 2100000 blocks (1block / min * 60mins * 24hrs * 365 days * 4yrs)

When will all be mined?

Tron one of the core team devs explained it on Telegram on the 30th March 2018 as follows:

"Half of Raven will be mined over the next 4 years or so.  Then another quarter over the next 4 years.   Then an eighth over the next 4 years, etc.   Most will be mined over the next 24 years, but it will continue for another 120 years or so.   Mining fees should support the Raven network as the block reward decreases."

Trading Questions

When will RVN be on more / better exchanges?

RVN is listed on multiple exchanges.

There's an exchange liaison group on discord with a number of people talking to exchanges and software and hardware wallets.

The group has a working document Exchanges and an Exchange FAQ on this wiki.

Mining

How do I mine Ravencoin?

There is dedicated mining page, including links to the opensource mining software for both nVidia and AMD cards. The Guides page contains multiple how to videos.

Can I mine with my CPU / CPU or GPU mining which is better?

CPU mining is not worthwhile anymore. You can mine with your CPU using the wallet (setgenerate true -1 to use all your CPUs, however you are extremely unlikely to mine a block). The network hash rate is very large so a single CPU isn't going to contribute much.

Which miner is best?

Miner Devs update their software very often. The best place is to ask on Discord #mining.

Which pool is best?

All the Pools are pretty good, and as with most things tech, they all have issues from time to time. On average you'll get a larger share of fewer blocks with the smaller pools and a smaller share of more blocks with the larger pools. There are support channels for most of the pools on Discord. The pools can be compared here.

Mining on a big pool will give you many tiny payouts, vs mining on a small pool will give you fewer large payouts. Over time it will average out and you will earn the same amount of coins.

A good recommendation when choosing a pool is any pool not in the top 3 highest hashrate, but any other pool with at least around 0,5% of network hash rate so the pool will hit some blocks each day. Or if we want to help build up a tiny pool, go for an even smaller one.

The reason we want to not go for the pools with the highest hashrate is to spread the hash and secure our network. Read up on 51% attack here.

When do we get paid

Payouts come from a block found by the pool that we have valid shares on. After a block is found it needs to be confirmed by the 100 next blocks, and since block time is 1min for Ravencoin this is about 100 mins. Coins are called immature while being confirmed. Once the coins are confirmed they are spendable, and will be paid out by the pool on the next payout cycle. Coins are often called matured coins at this stage.

I just started mining 30mins ago, why are my rewards so low

Pplns vs pps, is often the answer. In a pool with pplns - Pay Per Last N Shares - we build up over rounds(N) our share in the reward(block). Suprnova uses 20 - 25 rounds for N.

PPS - Pay Per Share, the sum of our submitted (accepted) shares divided by total submitted shares on the pool by other miners, gives us our percentage of the next block.

yiimp based pools (such as ravenminer.com, yiimp.eu, cryptopool.party) by default use a custom approach to rewards. All shares are saved for as long as it takes to find a block. Then, when a block is found: 1) rewards are divided proportionally among valid shares. 2) Valid shares older than 5 minutes prior to the block being found are then deleted. [1] This has the effect that all miners get close to a fresh start with each new block.

Pplns will give us more rewards in long term mining. Read more here and here.

Why is the difficulty going up / down?

The network tries to maintain 1 block being solved per minute over 2016 blocks before retargeting difficulty. If miners have found more than 1 block per minute during the previous 2016 blocks the network difficulty will go up to bring the average block time back to 1 per minute. If miners are solving blocks slower the opposite will happen.

Why is my hash rate going up and down?

The X16r algo consists of 16 different algos, and the order is based on the last 16 bits of the last block. We can get a better displayed hashrate on ccminer/nevermore by adding the following to the end of the bat file:

-N 600

What hash rate should I be getting for my cards?

There are some conservative numbers on WhatToMine

These are average hashrates (from multiple cards) from Nevermore 0.2.2 and Suprminer 1.6 with -N 600 (and more than 600 accepted shares):

Nvidia 1060 6gb pl 80%, core +125, mem +200  =  7-7,7MH/s
Nvidia 1070     pl 70%, core +125, mem stock =  9,5-10,5MH/s
Nvidia 1070ti   pl 80%, core +125, mem stock = 11,5-13MH/s
Nvidia 1080     pl 85%, core +125, mem stock = 13-14,5MH/s
Nvidia 1080ti   pl 80%, core +125, mem stock = 17-18,5MH/s

AMD sgminer avg since started (right column) 6 hour runtime, -X 256 -g 2 :

Amd 7950 3gb stock BIOS, pl 100%,  950 core, 1450 mem = 2,0-2,2 MH/s
Amd 570  4gb stock BIOS, pl 100%, 1256 core, 1750 mem = 5,6-6,0 MH/s    
Amd 480  8gb stock BIOS, pl 100%, 1303 core, 2000 mem = 6,7-7,1 MH/s

How do I do <topic here> with the wallet?

Many questions about the wallet can be answered by searching the same question for the Bitcoin wallet. The Bitcoin wiki and Bitcoin on StackOverflow are two great resources which might already have answers to your question.

How do I get a receiving address?

At the time of writing the Raven QT wallet is largely the same as the Bitcoin QT wallet - there are numerous guides via Google on setting up the Bitcoin QT wallet.

In summary, install the wallet then:

For a receiving address:

Click File > Receiving Address > New, enter a name for your address, click OK - you should then see your new address

There is a more detailed General wallet guide on Best practices page.

How do I set up the wallet to be a full node (and why would I?)

A full node validates transactions and blocks, which makes the whole Ravencoin network stronger. You can enable this by opening up the wallet and looking under Settings > Options > Network and making sure both "Map port using UPnP" and "Allow incoming connections" are both checked.
