Sorry if stupid question :
I have an old (pre)monero 0.8.8.6 wallet.bin file.
I ran 0.9.4.0 and when opening the wallet.bin file in simplewallet I get

Code:
Error: failed to load wallet: incompatible native format - size of long

What can I do ?  --generate-from-keys wallet.bin.keys ?

Thx for your advice.

In addition to other advices, make sure you are on the same operating system as the one where your old wallet was generated.

If you get rid of bin file (move/delete), then the keys file should work on any OS.


THX.
Indeed, it was an old win7 no-seed wallet I tried on Ubuntu. I moved the wallet.bin, kept wallet.bin.keys in the folder and opened wallet.bin with ./simplewallet like you said. It worked, first it had 0 balance, but after a refresh - which took a long time - everything was ok.

Hi GingerAle,

Thanks for your summary.

Two things I don't quite understand.

Quote
Blocktimes will also be changed to 2 minutes in order to try and fix the amount of reorgs that occur.

What are reorgs ?

Quote
Ring-confidential transactions will also be in the development branch at some point, which means that now the amount of a transaction will also be private

What do you mean it will be private ? Isn't it already private (with mixin) ? Am I wrong or are Confidential Transaction more obscure than current implementation ?


 

 

Hey everyone,
Can anybody provide a quick update as to what's been up to Monero development recently and what the short/mid term goals are.

Thanks.

I can provide a quick update, but I don't know if it will be a correct update Smiley

The current push is to get the 0.9 binaries released, which include major improvements over the last release. In-line with the development priorities after the block 20612 attack (https://bitcointalk.org/index.php?topic=583449.msg8677607#msg8677607), the primary improvements are in the underlying protocol. I can't give a full rundown of what these are, and its been listed somewhere before, but IMO a main improvement is the movement of the blockchain to an LMDB database. LMDB is quite an impressive database solution - it has dynamic memory usage, so if your system has the available RAM and bitmonerod needs it, then it will use it. However, once its done needing all of this ram (mostly during sync), the 0.9 binaries use about 50 MB of RAM. Furthermore, LMDB was built to withstand database corruption. So if you lose power, or your daemon exits uncleanly, your database is intact. This is in contrast to mostly all other cryptocurrencies that use bdb, which apparently requires re-indexing or something after not-so-uncommon events. Indeed, I find the fact that monero is the only cryptocurrency using LMDB kind of ridiculous, considering that the entire technology is based on a database.

Currently with work with the database improvements is to ensure all of the failovers / other implementations are functioning properly... i.e., a bdb implementation is still necessary for 32 bit systems, and ARM systems also require a different solution than LMDB, so I think these are the final sanity checks before 0.9 is released.

Another interesting improvement is change of the base cryptography to the actual standard, as opposed to the cryptonote version of the cryptography.

The above two instances sort of exemplify the work thats been done leading up to the 0.9 release - the cryptonote codebase was a bit messy (apparently... im just regurgitating what I've been told because im no coder). Thus, in order to actually make the network stable, the underlying code had to be improved.

Additionally, there are some pretty core changes in the protocol being implemented for an upcoming hardfork. Primarily, a minimum mixin will be required - this significantly enhances the privacy of the blockchain. For research in the minimum mixin and mixin 0 problem, check out one of the Monero Research Bulletins. Blocktimes will also be changed to 2 minutes in order to try and fix the amount of reorgs that occur.

Finally, a lot of work has been done in simplewallet to increase the utility of actually using the monero protocol / blockchain / network. For instance, one can now use integrated payment IDs, instead of attaching a payment ID to a transaction. This also increases privacy because in the cryptonote implementations, payment IDs are unencrypted / unmasked etc.... essentially just plain text on the blockchain. Now only the sender and receiver can de-code the payment ID. There are also view-only wallets, providing users with some security knowing that intruders onto their hardware can't use their bins to spend their monero. Simplewallet sync times have also been improved.

Thats the stuff that manifests most obvious to me, as a non-coder monero enthusiast that plays around with the software to beta test etc. This is probably a disservice to the coders that have worked on this, because there's probably a lot more.

The next wave of work going into the next release will also be amazing. 0MQ is already implemented in the development branch, and its quirks are being worked out. i2p integrating is also going into the development branch. Ring-confidential transactions will also be in the development branch at some point, which means that now the amount of a transaction will also be private.

The easy answer would be to point you here: https://getmonero.org/design-goals/

Long story short, if I had more money I'd be buying more monero.

I want to write a Dockerfile to run ./bitmonero in a dockercontainer. Which ports or range of ports must be exposed for the monero deamon ?  

EDIT : ok, seems to work with ports 18080 and 18081

Been a couple of weeks since I ran bitmonerod on win7. I tried 0.8.8.6 and 0.8.8.3 today and it seems my deamons won't connect with the network anymore. All I get is a constant stream of "incoming handshake,  failed ....." I'm stuck at block 502068. Any ideas ?

Hmm, I suggest we leave out US patriotic mentality and words like "founding fathers" and "constitution". Crypto and P2P are about anarchism, questioning every kind of authority, so I'd leave out every reference to nation states.   


You may not want him to print his ideals on crypto.  I understand that.  But in honesty I don't want your ideals to be the point either.  And it is not because I do not share some of them.

Cryptocurrencies will benefit crypto-anarchists, yes. This is by definition.  And there is no doubt they have the potential to interrupt the power of states.  But I have a more inclusive view of the power and use of cryptocurrencies.  And this movement is no the isolated playground of left-libertarians.

Also, to say they are about "questioning every kind of authority" is very short sighted.  The will form new authority structures themselves.  In fact this is the turn this conversation has just taken with the idea posed in the post we are talking about (the scheduled fork-dates).

My 2XRMR...

I follow you. GingerAle did a better job expressing my concerns :

Quote
I think the consensus mechanism would cover that, no? I mean, if a dev team changed the emission, we just wouldn't mine that branch.... right?

Why do you think "questioning every kind of authority" is short sighted ? The word 'authority' is key here. No man/woman or group should be able to impose something by decree, but this isn't the case anyway with decentralized systems.

I propose here to the core devs to use this opportunity to create a "Monero constitution", we'll have the current Monero developers as our "founding fathers" and a GPG document signed by them laying the principles of Monero and what can and cannot be changed ever (like emission).
http://forum.getmonero.org/4/academic-and-technical/303/a-formal-approach-towards-better-hard-fork-management?page=&noscroll=1#post-1246

edit: this is not of distrust of the current devs but binding the future ones that may come and try "USGavin it".

Can someone talk a bit about lending XMR in Poloniex? What are the risks? Does it worth it? etc...

My first steps in margin trading and this is my experience so far :

1. I bought a short position. The lending is automatic, meaning I (presumably) got the cheapest rate and the rate varies automatically when cheaper (lower rate) loans are offered e.g. initial BTC XMR lending at 0.0374% and during my position it went automatically down to 0.0365%

2. I offered a BTC loan at 0.045% for 2 days. The fees are accumulating as long as the lender doesn't close his position. 0.045%/day  = ~17% annualized, which isn't bad I think.

What I don't understand is my loan is still active at 0.045% while there are cheaper loans right now ? I'd guess the lender would get those cheaper loans automatically like I  did ?

I do not find the how-to but the github instructions are OK.
briefly on ubuntu 15.04, to make a "db" bitmonerod



Thx for the how to Arux.

Not sure Dockerizing Monero is usefull, but I'm gonna look into it once I've a better understanding of Docker.

Not using docker atm, but if there's some interest, I could publish Ansible roles for installing the daemon and simplewallet.


I'm not familiar with Ansible, how does it compare to Docker ?

If I remember correctly someone posted a 'How to' to compile and run the latest Monero + DB on Linux(Ubuntu or debian) some time ago. Can someone point me to this how to.

Question : is it possible to Dockerize (https://www.docker.com/) the deamon, the wallet and the DB ? Has someone done this yet ?

I am sorry that your explanation did not inspire confidence to invest in it. Despite my totally non-tech background, I know reasonably well how Monero operates, and it should not be impossible to gain the same understanding from emunie, although not from that explanation  Tongue

Yes, I would not recommend anyone make investment decisions from random forum posts, but I suspect you already know that Smiley Everyone needs to do their own research and make their own mind up. I was skeptical of emunie for a long while, but I am excited by their attempt to use the basic truth of the Quantity Theory of Money (MV=PQ) within a P2P network where all vaiables are known in real time, to achieve a worthwhile goal of price stability. Whether they achieve that is uncertain, but if they do then things will change quite a bit.

Why is this simplistic economic equation MV=PQ so popular, even among many bitcoiners ? It's pseudo science in my opinion.     

Aren't we just in these days worldwide witnessing that the equation is rather stupid and doesn't fit? It is pseudo science (and wrong at that even).

Well, actually I don't know, but it would make a lot of sense. I wonder if there is one equation that fits ? How would you take into account economic reality is distorted and manipulated by "the vile maxim of the masters of mankind" ?

Some experiments with D3.js ... it's a zoomable graph of XMR emission. Maybe someone can use it.

EDIT : Y-axis are percentages of total supply according to the emission formula


Neat! Does this incorporate the tail emissions? it stopped at 2040, so .....

I made a new graph with tail emission :

www.googledrive.com/host/0B8ddMzM9RWuROEVrbnE0U1RXaTQ

The model makes following assumptions :
* genesis block @ april 18 2014 00:00:00 (according to Moneroblocks.eu the first block was mined @ 2014-04-18 10:49:53 UTC, but something isn't working properly in my javascript code)
* every block gets mined exactly every 60sec
* it doesn't take penalties into account
* every block reward gets calculated according to the formula : (M - A) * 2-20 * 10-12 with A the current supply and M = Atomic Units = 264-1 and the calculated block reward is added to the current supply UNTIL the calculated block reward <=0.3 XMR
* Whenever the calculated block reward for block x <=0.3XMR the actual block reward for block x to block x+infinity becomes exactly 0.3XMR

Some calculations I made with this model (it calculates 26280000 blocks ~ 50 years) :
* first block with a calculated block reward < 0.3XMR is block 4269201 ~ 2022-4-30 (year 9) with a current supply = 98.29469862785216% of M
* block 5317920 ~ 2024-4-27 (year 11) is the first block for which the current supply >= 100% of M (from now on current supply grows greater than M ?)
* year over year inflation at the end of year 9 = 0.874171704788429%. (Indeed ~0.9% see Smooth's reply)
* year over year inflation is calculated every year. You can look at them by pressing F12 in your browser.

Javascript code is very messy, so I could have made a mistake. If something is wrong with my reasoning and assumptions for this model, or any suggestions to fine-tune the model, please tell me.

EDIT : definitions of A and M
16  Alternate cryptocurrencies / Speculation (Altcoins) / Re: [XMR] Monero Speculation on: April 12, 2015, 11:38:12 PM
When - what date or what blockheight - would the tail emission kick in ?  

It is hard to know the exact date/block because it depends on penalties. Each block's reward is a function of the actual number of coins created so far.

It will kick in whenever the reward according to the formula would be less than 0.3 XMR (approx 0.9% annually), which is expected some time around year 8.


Why 0.9%?


Edit: I guess what I'm asking is, what is the actual formula for the tail emission, the resultant inflation year over year and why was that amount chosen?

The formula is "0.3"

The amount was chosen based on being a round number within and close to the <1% inflation maintenance reward specified in the ANN OP.



I found this on github

Code:
+#define FINAL_SUBSIDY_PER_MINUTE ((uint64_t)300000000000) // 3 * pow(10, 11)

Does this mean a constant block reward = 0.3XMR ?

Neat! Does this incorporate the tail emissions? it stopped at 2040, so .....

It's simple javascript calculating the supply every minute according to :

* Actual number of atomic units is M = 264 - 1. A minimum subsidy may be implemented in the future with <1% annual inflation to preserve mining incentives.
* Uses a recurrence relation. Block reward = (M - A) * 2-20 * 10-12, where A = current circulation. Roughly 86% mined in 4 years (see graph)

You can copy paste the code and run it locally in your browser. The example calculates 525600*26 blocks (see javascript code) ... you can change that to any number you want.

When - what date or what blockheight - would the tail emission kick in ?  

EDIT : 525600*26 = 26 years each year 525600 blocks one block every min.

I do not see a 0.0028 to 0.0045 trading range, rather I see an upwards trendline channel with very strong support at 0.0028 with two scenarios. 1) Continuation of the trendline channel with a test of 0.0050 and a possible test of 0.0058. A break of the upward trendline would be very bullish and could lead to a test of 0.010. 2) My second choice is a breakdown of the bottom trendline and possibly a break below 0.0028.  

Hello ArticMine,

How do you view Poloniex BTC/XMR in tradingview ?
