161  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [BBR] Boolberry: Privacy and Security - Guaranteed[Bittrex/Poloniex]GPU Released on: December 31, 2015, 05:32:30 AM
i don't expect squat (re price) with then new release unless their are those that "invest" based on "performance" of a core team.

i mean, really, besides the ability of the network to perform its primary function, there is the ability of the network to perform that function in a secure fashion. 0.9 will allow many more nodes to come online... we've all witnessed newcomers to the scene be like "yo i downloaded this thing on the website and wtf". So 0,9 will make that whole situation somewhat better.

but as was eluded to in that fast talkin bitcoin podcast, its all about network security. And our hashrate just doesn't cut it yet. What cuts it? I have no idea. As a supporter, you can do many things:

1. run a solo node and mine on it
2. build up massive mining infrastructure
3. keep the price high

the current evolution of crypto allows #3 to work in some extent to address the overarching problem - lack of net hash. If monero was worth 10$ at current emission, what would the net hash be? so many cloud services would be burned keeping it up. But thats not what we want. We want a natural net hash. We want organic. Home grown. A real network of contributors. A real network of miners with dedicated rigs.

Yes it has been posited that we're just not there yet to justify high net hash..... but when? when the emission curve is bollux?

Important post from Monero thread that is just as (and arguably more based on our lower hash rate) important for boolberry

#1 is a very easy thing to do. Any believer in Boolberry should absolutely start solo mining today to support the network regardless of profitability. If your profitabilty calculations (based on your equipment and electricity costs) tell you it is more "efficient to just buy on the exchange then buy on the exchange AND mine Boolberry. It is the right thing to do and essential to network security.

Start mining!

I thought this was an informative post about CryptoNote block sizes and block subsidies
https://www.reddit.com/r/Bitcoin/comments/389pq6/elastic_block_cap_with_rollover_penalties_my/crts1do

quote from cloud10again:
https://www.reddit.com/r/Monero/comments/3ypd46/please_help_with_user_guides_and_other/cyftd1w

Note that the way it's written is somewhat confusing, and the last 2 needs to be superscript.

Here's my attempt (assuming I'm understanding it right):

Reward = baseReward - baseReward * (currentSize / medianLast100 - 1)2

As bitcoin continues to struggle with scaling I hope more people notice the solutions already built into CryptoNote coins.  The tail emission for Monero is another positive that will likely prove very hard for bitcoin to implement.

Privacy coins were a fad in May 2014.

Newton was a fad.  Palm was a productivity tool.  Usability features are converging, and the demand will come, inevitably.  As long as the usability is there when the demand spike emerges (at some sweet, stochastic moment) the outcome should be quite nice.  Maybe it needs a GSM radio to reach a subsequent tier of market expansion, but first things first, walk then run.


How many of you are expecting a demand spike with the next release? To me the db work is more important than the GUI but I suspect the general population (even those who care about privacy) will disagree with me for usability concerns.

1. db plus command line works well for me already

2. Some (less concerned with security and to some degree privacy) will think mymonero.com is sufficient

3. Will those who want the new db and an official GUI (as opposed to existing "unofficial" 3rd party solutions outnumber both groups 1 and 2 above?

Monero Missives

In this week's episode we interview psi, from the I2P project, and also announce the new Monero Kovri project, an open-source C++ router. The source can be found here: https://github.com/monero-project/kovri   Until next week! (this is now a running joke...right guys?)

In case you don't have iTunes -> http://podbay.fm/show/1032156854/e/1451151298?autostart=1

EDIT: FYI: There is some discussion in the missive about I2P vs TOR. However, if I understood correctly, you can run I2P either as I2P-only, I2P/IP bridged or IP-only (see -> https://getmonero.org/design-goals/). Thus, the latter will still make it possible for you to run Monero over TOR socks. I am not entirely sure about this, so if what was stated is incorrect, feel free to correct me.

Nice update! I enjoy the missives

kudos to those who were opposing draw earlier. I think a non draw outcome is a real possibility now.

The position definitely looked drawish earlier and that result may still occur.  I just felt like that since both sides had possible pawn breaks to open the position a draw at that time was premature.

I like our position right now but we will need to keep a careful watch on the a5 pawn for the rest of the game. Whites bishop being on a light square (controlling the queening square a8) makes it very dangerous.

Both Boolberry and Aeon already offer pruning. Boolberry has done so for over a year already

3. Blockchain bloat solution (already implemented):
http://boolberry.org/files/Boolberry_Reduces_Blockchain_Bloat.pdf


Pruning FAQ

Q: What is pruning?

A: Pruning refers to removing unnecessary information from the blockchain once it is no longer needed.

Q: What are the advantages?

A: Pruning reduces the amount of storage needed for the blockchain. If the blockchain is loaded into RAM (which is the case in the current implementation), then it also reduces RAM usage. Finally, it also reduces the rate that these resources are consumed over time as the blockchain grows. In the current implementation, each time one new block is accepted, one old block is pruned, on average freeing up a large portion of the resources needed for the new block.

Q: How does pruning affect functionality?

A: The only inherent functional limitation of AEON's pruning is the inability to restore (also known as rescan) a wallet which was used for spending transactions. All other functionality including sending and receiving coins, mining, updating a wallet after any period of inactivity, cold storage, mining, etc. remain fully supported. There is a current limitation that after extended period of disconnection (>28 days) a node may have trouble resynchronizing with the network, and would need to be reset. This is not inherent and should be addressed later.

Q: Does pruning reduce the effectiveness of ring signatures for transaction privacy?

A: No, ring signatures and privacy are unaffected.

Q: How is pruning enabled and disabled?

A: Using the --pruning option on the daemon command line. With this option the daemon will prune the blockchain and will also switch from using the blockchain.bin file for storage to blockchain-pruned.bin. To switch an existing node into pruned mode, copy blockchain.bin to blockchain-pruned.bin before starting the daemon with --pruning. To switch pruning off, remove the --pruning option. Do not, however, copy blockchain-pruned.bin to blockchain.bin. This will not work. You will need to have an unpruned blockchain.bin file or resync unpruned from the network.

Q: How does AEON's pruning compare with Boolberry's pruning?

A: AEON prunes slightly more information from the blockchain, so the required storage is slightly smaller (given equivalent usage), though the difference is likely not particularly significant. BBR prunes the blockchain on the entire network while AEON prunes on each node individually (and only if pruning is enabled). This means that new nodes can come online faster with BBR, but those new nodes are unable to independently verify the entire blockchain. It is possible to download an unpruned BBR blockchain from a web site to independently verify it, but in that case the amount of data downloaded would be the same as AEON. It also means that every BBR node is able to serve the chain to new users but in AEON this function falls to nodes that are unpruned, also known as "archive nodes" (or alternately via a trusted bootstrap file).

Q: How does AEON's pruning compare with Bitcoin's pruning?

A: In Bitcoin 0.11, the same model of pruning is implemented as in AEON. That is, nodes prune blocks locally, after syncing from an unpruned chain and verifying the chain independently. Like AEON, Bitcoin pruned nodes can't rescan or reindex wallets. Bitcoin 0.11 does not support wallets on pruned nodes at all, so it currently has more limitations that AEON. Old Bitcoin blocks must be retrieved from unpruned archive nodes, as with AEON.

Q: What other coins implement pruning?

A: Other than Boolberry, Bitcoin, and possibly some coins which have inherited their implementation by being Bitcoin forks, no other coins implement pruning at this time.

Q: What's this about "archive nodes"? How can I run one?

A: When nodes connect to the network, they retrieve blocks from other nodes. If only blocks within the most recent 10 000 (approx.  28 days) are needed for syncing, even pruned nodes can provide them. However, in the case of nodes which are brand new (syncing from the genesis block) or which have been offline for >28 days, pruned nodes will be unable to supply the older blocks. Instead this task falls to unpruned nodes, also known as archive nodes. For the time being the project-run seed nodes will always run in unpruned mode, and others with sufficient RAM and storage space who wish to support the network are also encouraged to do so. To run an archive node, simply start the daemon in the normal manner, without the --pruning option.

Q: What are the numbers? How much does pruning reduce the amount of memory and storage needed?

A: The exact numbers will vary according to OS, compiler, etc. and also depend on the usage of the blockchain in the future. One early report from BoscoMurray stated, "RAM usage down from 4.8GB to 2.4GB and blockchain file size down from 3.2GB to 1.7GB"

Q: That doesn't seem like a big reduction. Why is the benefit not greater?

A: To explain why the reduction is not larger and understand what this means for the future, let's first review some basics of how a blockchain works.

Every time a coin is spent, a digital signature accompanies the transaction in order to show that the owner of that coin authorized spending it. Once this signature is checked, it is no longer needed. This is the largest portion of what is being pruned. In the cryptonote signature scheme (used by AEON), ring signatures used for anonymity, which means while a signature shows the coin owner authorized the transaction, unlike conventional signatures, it does not identify the specific coins being spent, and therefore does not allow tracing and analyzing the blockchain. As a side effect of this functionality, these signatures are much larger than ordinary digital signatures (a fact sometimes described as "cryptonote bloat"). Thus in AEON, pruning offers great benefit and eliminates the "cryptonote bloat".

So why is the savings not larger? Because in the early history of AEON, there was a very large number of very large transactions and many of those transactions did not using ring signatures. This happened for several reasons, including a major flaw in the early versions of cryptonote mining pool software. Thus, while the chain is relatively large, a relatively small amount of storage is saved by pruning the early transactions.

The newer transactions are a different story. The pool software flaw was fixed long ago, and most transactions now do use ring signatures. So the savings from pruning going forward should be much higher (perhaps 75-80%). Of course, since ring signatures are now being routinely used, it means that that actual anonymity of the coin in practice is greatly improved, and with pruning there is no long term storage cost (i.e. no "cryptonote bloat") for most nodes (other than archive nodes). We get the best of both worlds!

Q: What about a database or disk-based block storage? Doesn't that also reduce memory usage?

A: Storing the blockchain out-of-memory in a database or in cache files reduces memory usage but does not reduce storage usage nor reduce the rate of growth of storage usage over time. In AEON, the plan is to later support out-of-memory storage of the blockchain along with pruning, so memory usage will be further reduced, and storage usage will remain low and grow very slowly over time.

Bitcoin compatibility is probably the biggest issue with adoption on all these coins.

This is likely to be the case. CryptoNote was designed to be different from Bitcoin; even its whitepaper is written as opposed to Bitcoin architecture. Therefore, the API is incompatible. This would not be a drawback in case of higher demand/hype, but in reality this may hinder CryptoNote much more than blockchain bloating.

Monero is doing API work and other CryptoNote coins will as well:

https://bitcointalk.org/index.php?topic=949393.0


Monero API .NET
API for data transmission and retrieval from Monero applications through the Microsoft .NET Framework

GitHub repository | NuGet package

This project allows developers to flawalessly access the functionailty of Monero applications through the Core assemblies' RPC services. As the software is open-source, everyone can contribute, achieving the best performance and reliability for end-users.

Why is this API necessary?
It makes the implementation of Monero extremely easy for merchants, wallet builders, and all the other developers who are interested in working with (or accepting) Monero. Also, the core developers can concentrate more on the internals (instead of spending time on the official GUI client), which means that the currency should advance faster.

Is it cross-platform?
The first 3 releases of the API were only made for desktop PCs running Microsoft .NET Framework 4.5 or higher, thus, resulting in a smaller userbase than wanted. Since v3, the project has been split into 2 subprojects, one which is responsible for communicating with the daemon and the account manager's RPC channel, and one which can manage the required processes on PC.

What kind of platforms can utilize the power of Monero API .NET, then?
Basically every device which has support for running the Microsoft .NET Portable Framework v4, and more: Microsoft is planning to provide native (C++) compilation of C# assemblies very soon, and this process can be even faster since .NET Core has been made open-source.
The project can run on PCs (Windows; Mac and Linux with Mono .NET), mobile phones (Windows Phone; Android and iOS with Xamarin), and even on video game consoles like Xbox.

How does it work?
As I have already mentioned above, the project consists of 2 parts: MoneroAPI, and MoneroAPI.Extensions. The first one is built as a PCL (portable class library) and is multiplatform, while the extensions are desktop-only and contain functions for hosting a full node. Basically, MoneroAPI is preferable for lightweight, client-only applications, and MoneroAPI.Extensions adds support for hosting the Monero Core processes with ease.
There is a demo project included in the GitHub repository for a more technical explanation.



Please consider donating to one of the addresses in my signature if you like this project or want to support its development.

However this thread is about blockchain size not APIs.

I still think Kg7 is only option. Maybe not h5 right away after g4, but first Re8. The white position has a weak spot with g4. We better exchange queens if our queen is only defending a pawn, and the white queen has many attacking threats. Also Re8 right away is better than Rc8. That Qf8 variant I overlooked, but saying I have no clue makes no sense.

Just trying to make suggestions, so together we find the best move. That's why I asked if I only give my move, or also give suggestions. I hope you all look at all the possibilities Kg7 gives, that was my only intention. Kg7 to me looks like our only chance.

Best case Kg7 will transpose the the line I already gave. Worst case our king will be on a slightly inferior square in the endgame. For that reason Re8 before Kg7 seems slightly more accurate and flexible as it gives us the choice below which would otherwise be missing.

I still think Kg7 is only option. Maybe not h5 right away after g4, but first Re8.
30.Qxe5 Qg6
31.Rc6 Kg7
32.g4 Re8
33.Qxe8+ Nxe8
34.Rxg6+ hxg6 (34.Rxg6+ Kxg6 would not be an improvement for us because after 35.Bc4 our king would be misplaced on the b1-h7 diagonal allowing white to gain more time. 34.Rxg6+ fxg6 looks bad because of 35.Bc4 a5 36.Bxd3 h5 37.Be2 hxg4 38.fxg4 Nf6 39.Nc4)

The line above transposes to my original line except that we now have a choice of where to move our king on move 34:

30.Qxe5 Qg6
31.Rc6 Re8
32.Qxe8+ Nxe8
33.Rxg6+ hxg6
34.g4 (we now have a choice of Kg7 or Kf8 breaking the pin on our f pawn. I think Kf8 is better as a slightly faster way of centralizing our king)

Upon further inspection I have decided that this endgame (after Re8) will be a harder to draw than I originally thought (but still very possible). I have decided to vote for Rc8 instead and keep the queens on the board. The queen endgame will not be simple either so this vote is primarily a matter of taste.

I looked at the position some more and remain certain Qg6 is the best move. If our opponent plays Rc6 next move we need to have an important discussion. I still cant decide between Rc8 and Re8 (after Rc6). It is hard to determine if one option is much better than the other. Do we want to keep queens on the board or not?

29.Rc1 essentially ended our attack and we are now headed for an endgame. Our winning chances are over but I think we have excellent chances to draw even after losing a pawn. Here is the best I can see for both sides. Most of the moves below look forced to me. After we play Qg6 our threat of Re8 followed by Re2 is pretty serious.  I cannot find any good options for our opponent besides 31.Rc6.

30.Qxe5 Qg6
31.Rc6 Re8
32.Qxe8+ Nxe8
33.Rxg6+ hxg6

Both 34.Bc4 and 34.g4 should give white a small advantage but I think we have excellent chances to draw. I cannot see any other options for us that do not lose on the spot.

I think we have better chances by keeping the queens on and therefore 31..Rc8 32. Rxc8 Bxc8.

Draw with the black pieces is never bad against strong opposition anyway.

Your 31..Rc8 idea is indeed another clever option taking advantage of the same back rank threats at  31..Re8.

Since 31..Rc8 32. Rxc8+ Bxc8 33.Bc4 would also win a pawn for white I feel like we might be better off trading queens but maybe things are not so clear. I feel like our king is more vulnerable than his since we have a pawn on g5 with the queen on the board.  I should look at the position with the queens on the board more carefully. It sounds like we agree on our current move. If White plays 31.Rc6 as we suspect we can discuss this again.

Well, weŽre a pawn up as it is so losing one may not be so horrible.

HereŽs a line: 30. Qxe5 Qg6 31. Rc6 Rc8 32. Rxc8+ Bxc8 33. Bc4 Bd7 34. b3 g4 35. f4 Bf5 and if 36. Bxa6 Ne4 with excellent prospects for black.

I like that for us too. However I think white may play 34.Qd4 instead of 34.b3 so that g4 can be met with Bxd3. I will think about this some more before we need to make a decision.


34.Qd4 Bxa4 heŽll get the b and d pawns resulting in even material but it takes two tempos which should give us time for some counterplay. The position is becoming rather simplified at that point.

I think you are right that we have good chances in that position too. Tomorrow I will look at it more and try to compare that position to the one where we trade queens. My feeling is that we will have a slight disadvantage in both. I still have not decided which one I prefer.

Thank you, but we won't play Rxd2, but Be6 for example. But I am just trying to make suggestions, I decide during daytime.

No problem. I want to look at the position more too. Usually we get at least 24 hours (and often more) to decide on each move.

Thank you, but that is what I thought I said: "Bg2+ has some funny effects, but won't work out." 30. ... - Bg2+ is funny, but not ok.

After 30. .. - Re8 31. Qxf6 - Re2, not Bg2+. If Qd8+ - Kg7 / Qxd3 we win his queen with Rxh2+ etc. But I look at it during daytime, after 4 am here, my eyes are closed and my brain not working properly.

30...Re8 31.Qxf6 Re2 32.Ne4 d2 fails to 33.Nxd2 Rxd2 34.Bxf7+ Qxf7 and Qxg5+ forking the rook.

I am trying to think of a good alternative to 34...d2 for us but I don't see anything.

HereŽs a line: 30. Qxe5 Qg6 31. Rc6 Rc8 32. Rxc8+ Bxc8 33. Bc4 Bd7 34. b3 g4 35. f4 Bf5 and if 36. Bxa6 Ne4 with excellent prospects for black.

I like that for us too. However I think white may play 34.Qd4 instead of 34.b3 so that g4 can be met with Bxd3. I will think about this some more before we need to make a decision.
