[Serious, long] My thoughts on what next for Dogecoin

There’s been a lot of discussion in recent days about the decreasing price of Dogecoin, as well as the risk of a 51% attack from Wafflepool or similar. I wanted to do a wrap-up of the discussions happening amongst the developers of the last few weeks, partly to illustrate that we are looking at options, but mostly to talk about what is happening. Please note that this is all rapidly changing. Dogecoin is actually moving at breakneck speed for a project of its size, especially as we still have a relatively limited core team. This is part of why we don’t write posts very often, as they become out of date so quickly as new arguments and facts are presented.
Lets talk about 51% attacks first. The theory is that if anyone has over 51% of the total hashing power of the network, they can form a blockchain of their own which is considered “more valid” than the blockchain most users are on. This is because cryptocurrency blockchains are secured through proof of work, and therefore more work on a chain makes it, in essence, more valid. This risks an attacker spending coins on one chain, then releasing their own private, longer, blockchain. That latter blockchain replaces the original blockchain, and the coins they spent on the original blockchain are effectively returned to them as if the transactions never happened.
It’s important to understand this because I hear suggestions that Wafflepool shouldn’t accept over 51% of the network hashrate, and unfortunately all this would do is hide the risk. Having one pool own over 51% of the network hashrate is not a problem if it’s actually being used to mine, but instead if it’s used to create a personal blockchain. The other issue raised is one of price; we’ve been steadily dropping since around early February. The core of my answers here is that you need to consider demand vs supply. What happened back in February was that we saw a surge in demand beyond sustainable levels, likely in a form of tulip mania. As supply continued (mining), and demand dropped-off, our price has dropped. This has been worsened by a succession of bad news affecting Bitcoin (MtGox and other exchanges struggling, uncertainty of China and Russia, etc.), which both directly brings down our price, as well as undermining confidence in the entire cryptocurrency ecosystem. It has been suggested (and I can believe this, but have not done my own analysis) that as multipools continue to dominate Dogecoin mining, and they tend to sell coins directly, that they are further reducing the price. Specifically, given that while there is demand for further coins from miners, as they have already expended resources on mining hardware they cannot then purchase the cheap coins the mining pools are producing.
Lastly, there’s the question of ASICs; these are specialised mining devices which are significantly faster than CPU/GPU mining hardware, and typically cheaper to run due to reduced power and space requirements. Their introduction into mining at the moment leaves vastly disproportionate mining power in the hands of a few (there’s one individual with a hashrate of around 20GH/s, for example), and in time is likely to make mining on commodity hardware infeasible.
We’ve had a lot of suggestions for what to do; change proof of work algorithm, add multiple proof of work algorithms, move to proof of stake, merge-mine with Litecoin, have DigiShield merge-mine with us. We’ve considered everything, and then some; I’m not sure how much discussion has happened in total, but I’ve spent over a dozen hours looking at these issues on IRC. In virtually all cases, the majority of people with the skills to implement these changes have rejected them as too high risk and/or having other significant drawbacks. In summary:
The best suggestion we have so far is to out-do the multipools directly, by working on open source multipool software which is more DOGE-friendly. As I understand it two key approaches are being considered for improving DOGE-friendliness; either by directly exchanging other coins to DOGE, or through improved trading algorithms which result in less sharp shocks to the price. For very large mining farms such as SFire’s, it’s hoped this will cause them to separate from the mining pools (which they pay fees to) and go solo. This reduces fees for the miner, as well as reducing the ability for DDoS attacks to be targeted at them, and for us it reduces risk of a 51% attack, improves confidence in the coin security, and enables us to better mitigate impact of people mining huge quantities to sell.
Meanwhile, the main focus is on making Dogecoin (and cryptocurrencies in general) a viable way of moving value around. The 1.7 client (beta release is imminent, and in fact if you’re comfortable compiling it yourself, the code is available from https://github.com/dogecoin/dogecoin/tree/v1.7.0-Beta-1 ) is a major re-write of Dogecoin Core to base it on the Bitcoin Core 0.9 client (with Scrypt added in, of course). This gives us significant performance improvements, as well as a better underlying architecture. To repeat; this will not be a required update, although it will be strongly encouraged as it’s a huge leap forward technologically. One of the features which is currently not working in 1.7, but will be for release, is the Bitcoin payment protocol, which massively improves the payment request/receiving process for merchants. Fundamentally 1.7 is intended to prove we have the technical skills to maintain a stable, useful coin, and help drive/support adoption.
Once 1.7 is done, my immediate priority is technical documentation; we have a security specialist currently working on a guide to cryptocurrency security (setup, risks, best practices, etc.), to help give merchants and exchanges an in-depth understanding of how to securely use cryptocurrency. I’ll be addressing the need for formal standards in Dogecoin, and preparing RFCs for the “dogecoin:” URI and relay network protocol for submission to the IETF (and IANA for the URI).
Lastly; there was a post recently about the need for multi-signature addresses; I’d like to add my own “hell yes!” to that, although obviously I have to prioritise. If anyone else can look at these, that would be fantastic.
For anyone wanting a more permanent link, there's a copy of this on my blog ( http://jrn.me.uk/wp/what-next-for-dogecoin-mid-april-2014/ ), however posting as full text here as probably easier for most people, and I'm not sure my server would survive a reddit hug!
Edit: It's been pointed out that there's no verification of the problems with Blackcoin, and the source alleging problems has a serious credibility issue. Have removed the reference now.

[uncensored-r/Bitcoin] Bitcoin miners for rent! (Drumming up interest!)

The following post by xXBeefyDjXx is being replicated because the post has been silently removed.

The original post's content was as follows:
Hi everyone @bitcoin!
Me and a friend have had a serious steal of a deal on some mining equipment.
We will have in the region of 2-4 Terahashes of power to rent out if this goes through.
We will be splitting it between 100-200 users.
I want to know if anyone would genuinely be interested in renting out a cheap slot on my miners! They will be publically listed in the site "Miningrigrentals"
I am looking to rent out on a daily basis per slot, so you would be looking at 20GH/s per slot for 24 hours, and I might open up more time scales such as 2day-1 week slots at discounted prices.
Drop a comment if you would be willing to rent!

AMC Announces World's Fastest Bitcoin Mining Chip

SPRINGFIELD, MO, - June 27, 2013
Active Mining Corporation (AMC) and Virtual Mining Corporation (VMC) are announcing today the preliminary results from VMC's partner eASIC (www.easic.com) regarding the performance of the Fast-Hash-ONE Bitcoin mining chip, built on eASIC's top of the line 28nm technology.
Each chip holds 20 miner cores, with an expected frequency from 800MHz (16GH/s) to 1GHz (20GH/s). This is possible thanks to eASIC's expertise and AMC's heavily optimized design, making Fast-Hash-ONE the "World's Fastest Bitcoin Mining Chip".
The chip is expected in limited quantities in Q4 2013 and fully available in Q1 2014 and will be the backbone of AMC's drive to be the "World's Largest Bitcoin Mining Farm".
See our thread on bitcointalk.org for more information.

Free Bitcoin Mining

Go to hashie.co for a free 10GH/s miner. Makers about $0.03USD/day/10GH. You need to purchase a miner to send money to your wallet. However you purchase miners in bitcoin. One 20GH/s miner is about 0.024 BTC. It's faster to send bitcoin there to buy the miner. Though you could just wait 300 days to get enough bitcoin to buy a miner. All for free.
