The best part of this comment is that Steemit used to have a real-life Dale Gribble, too.
Congratulations to all involved in the development of MIRA.
This is indeed a red letter day and an amazing transformation in the effectiveness of Steemit Inc in delivering what the Steem community really needed from them.
I posted about how important the ability to run a Steem node on commodity hardware was immediately after Steemit Inc announced the 70% cuts.
You have really turned things around. Well done.
I really dont care to educate myself on what is what. All i care about is one word:
and how @andrarchy can take that word and mold it into a 100 different versions, comparisons with other blockchains to show twitter, facebook, Reddit how STEEM compares.
Doesnt matter how it works. All that matters is that it does work and that the shill info is so good that the receiving end doesnt even mind, because its just so beautiful..
First of all this is a monumental moment in Steem's history, the costs of running 3 year old blockchain will be cheaper than ever, I don't think many people understand this. Every blockchain that gets bigger over time is more costly to maintain, with MIRA Steem can be run by almost any PC configuration.
I have one question though, are there any bottlenecks left that would prevent Steem for massive influx of people, something that would potentially be another 1year development cycle problem?
I've always wondered about the whole 'logistics' of steem/blockchains; of course modern computer processing speeds are hard to even wrap your head around, I can't help but sometimes wonder how 'long term' feasible block chain technology is... I mean every three seconds there's more data to be processed. Admittedly I'm not a computer scientist and I'll leave this speculation up to people that are more informed on the subject. But I like what you're saying!
Wake me up when we have communities :)
Couldn't the government narrow down who's running a node in DPoS? I was reading how centralized nodes aren't very decentralized.
dPOS is centralised to a permissioned set of block producers, right. When they speak about "decentralisation" they mean that they have lowered the economic hurdles for you to take part in this political process of becoming a blockproducer. So technically it does not decentralize anything. But dPOS is obviously not relying on topological decentralization, it relies on delegating power to representatives of which 21 will produce the blocks.
Since voting in Steem is plutocratic (dependent on your money) it is not democratic and heavily biased towards creating circles of power and influence. The "government" does not wnat to discuss this aspect...obviously they are not interested in "power to the users".
Well played! This sounds like a huge milestone accomplished.
You're very eloquent @vandeberg! Congrats on this remarkable work and I hope we'll get to hear you more in the future!

Reading about MIRA, this will definitely decrease cost to run blockchain and helps more people to help to be part of steem development. We are grateful for all the developers like you.

It will be much faster loading for endless scroll if there are no ads. But yes I know ads are now relevant for profitability so we do understand that. Thank you for this update and will check out MIRA as another promising SMT to watch out for.
Goi g to check this out now 😀

So you're telling me EOS will be screwed by scaling (like Steem did, until RocksDB/Mira go implemented)? 😃
Well "screwed" is a difficult term. One could argue that as long as the EOS stakeholders are making money, they're not screwed. Let's put it this way; the EOS main chain is already over 5TB and it's still all in RAM. A big part of the reason why it's so big is because it produces blocks every half a second. But none of this is necessarily bad for Block.One because they don't run the chain or run an app on the chain. The people who will get screwed are the suckers who choose to build on it ;)
5TB !!! That's insane. I thought EOS was going to produce every 3 seconds like Steem.
And growing! Rapidly! Good thing they spammed all those transactions ;). They need to produce blocks that frequently if they want to deliver the kind of performance they are claiming EOS is capable of. Imagine someone wants to string together 20 smart contracts all of which need to be executed sequentially, before funds are transferred. That one transfer is still going to take 10 seconds to occur even with .5 second block times. Had they chosen 3 second block times... well you can do the math. Not saying it's a bad solution to the problem they're choosing to tackle, but it highlights part of the reason we're so committed to application-specificity. For Steem, 3 second blocks work great and few see any reason to increase that rate, especially bearing in mind that doing so would only make the chain grow faster.
That is great work and I hope there will be some updates once thing settle to look at the numbers in regards to performance and savings.
Thanks for your nice summary and very honest interview. Good to see you on Steemit as well as GH :)
ps. don't forget to merge the 14-week powerdown fix haha :)
One more reason to continue working with steem blockchain.

@vandeberg, you are a rock star. Thks for your contribution to steem blockchain and to the world. I remember chatting with you during steemfest 2. Not many people get to know the engineer behind such project. Congratulation to the team for MIRA roll-out.
Great work!

Thanks for explaining more about the recent adoption of the steem blockchain. I hope it will more positive value to our community
This is a great breakdown for even those of us that are less technical. I would love to eventually run a node or even be a witness to support the further decentralization of the protocol and this makes it easier!

Where is the github code for MIRA? Thank you
Edit: I think I found it:
https://github.com/steemit/steem/tree/8dc43704f7abf65b5ca9e737b965de964be9779c/libraries/mira
This post has been included in the latest edition of The Steem News - a compilation of the key news stories on the Steem blockchain.
Oh the irony of this development. I'm glad that the scaling issue is being solved. The fact that a database technology that was developed by Facebook (arch-enemy of Steem.... Hahaha) and is now going to be what possibly saves the day for Steemit scaling. Congrats gentlemen.
Bravo Michael!
To me, this is BY FAR the most important technical Steem improvement, ever. Exceptional work, keep it up!
Kind regards, @scipio & @steem-ua
FYI, I included this post in my Interesting Links post for May 8. You'll receive beneficiary rewards for 5% of that post's payout.
Very nice @vandeberg, to find this post and listen to your explanation of what MIRA represents. While I do not have the level of expertise you cite, I have worked with normalized data structures for years. Through the need to understand what an application like MS Access can provide in the way of business solutions (like currently working on one to handle our family’s tax reporting requirements …).
So … This was more than a “casual” post reading for me.
Given your background and role, I have a question which is very important to me as an investor. It pertains to the whole “open source” approach to solving “real world” problems in advancing the capabilities of this new “digital asset” class. My question is how much confidence you have in yourself and your fellow “open source” co-workers that no “trojan horse” code could be introduced into it somehow / some way by a “hostile” agent of some sort?
My concern is that this is theoretically possible. I won’t take your valuable time to “spell out” what I mean by hostile, as I imagine (I hope …) you may have thought of those possibilities yourself. What I am asking is for your answer to the question, with the hope of receiving some assurance there are some very good programmers who are ever watchful, for just this possibility. Sort of along the lines of the famous quote:
My sincere thanks to you and @andrarchy, for the effort to get this post made and out for us. Supported and resteemed, to do my small part to improve the understanding, of those of our fellow Steemians who may be interested, of how our Steem blockchain works "under the hood" ...
P.S. Also bookmarked in SteemPeak … 😉 … for future reference ...
good job !!!!!!

Can you open with:
MIRA: Steemit on the Rocks
or something? :)
That's nice! I rented a server with 160GB SSD, but the witness installer that I found load a very big block_log, that doesen't fit on the SSD. Now Iam installing the github steemd, which last 4 days now and is still at half of the chain. Where do I find that mira update or alternatives for my server?
This is awesome @vandeberg
