Compile Bitcoin on Ubuntu 14.04 · GitHub

Can't install bitcoin-qt in ubuntu 14.04 with ppa

In the terminal I entered these 3 commands:
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install bitcoin-qt
After entering the last command it says:
The following packages have unmet dependencies: Bitcoin-qt : depends : libqrencode3 (>= 3.2.0) but it is not installable E: unable to correct problems, you have held broken packages.
PS I am running ubuntu 14.04 from a cd
Thanks!

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.

Video

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

Bitcoin Full Node on Ubuntu 18.04

Need help! I feel like I am missing something stupid small here. I am trying to run a Ubuntu based Bitcoin Full node. I am trying to run this on on a VM Box in VMWare ESXi 6.5. I have tried Ubuntu Desktop and Server 12.04, 14.04, 16.5, and 18.04. The VMWare box has been giving 6gb of ram, 1TB of storage, and 4 CPU Cores. All of them seem to have the same problem. They freeze my entire box. Usually, the freeze occurs while syncing headers but could happen even while trying to connect to neighbors.
I uses these scripts to install Bitcoin Core:
sudo apt-add-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install bitcoin-qt
Has anything heard of this before? I feel like I am late to the party but I cannot find a way around this.

Bitcoin ABC Ubuntu repo has been updated to serve 0.17.2

Bitcoin ABC Ubuntu repo has been updated to provide the latest stable version 0.17.2
See the release notes for more details.
Repo home page:
https://launchpad.net/~bitcoin-abc/+archive/ubuntu/ppa
If you are installing for the first time just execute these commands(*):
sudo apt-get install software-properties-common sudo add-apt-repository ppa:bitcoin-abc/ppa sudo apt-get update sudo apt-get install bitcoind bitcoin-qt 
(*) if you already have a prev version of Bitcoin ABC just run:
sudo apt-get update sudo apt-get upgrade 
 
 
If you are experiencing an error related to libstdc++6 version being not satisfied, look at this abcbtc's comment that contains the fix:
 
https://np.reddit.com/btc/comments/7a3jtg/bitcoin_abc_ubuntu_repo_has_been_updated_to_serve/dp6w39p/ i.e.
 
sudo add-apt-repository ppa:ubuntu-toolchain-test -y sudo apt-get update sudo apt-get install libstdc++-7-dev -y 
 
If you are using Ubuntu 14.04 (Trusty) you also need to execute these commands before installing the Bitcoin ABC binaries:
sudo add-apt-repository ppa:sickpig/boost sudo apt-get update 
This is needed due the fact ABC bumped min version for libboost to 1.58.00 .

Discord Log from Ravencoin Open Developer Meeting - Oct 19, 2018

RavencoinDev - Today at 2:03 PM
Hello Everybody, sorry we're getting started a couple of minutes late today.Today we wanted to make sure that everybody was aware of the Bug Bounty program and discuss it.Has everybody seen the information at https://github.com/RavenProject/Ravencoin/wiki?GitHubRavenProject/RavencoinProject staging tree. Contribute to RavenProject/Ravencoin development by creating an account on GitHub.📷

Hans_Schmidt - Today at 2:06 PM

Yes. I'm working on it...📷1

RavencoinDev - Today at 2:07 PM

I have seen that @Hans_Schmidt Thank you for really digging into the code. You have found some really good ones.Did you get an address posted in the issues so we can reward you for your efforts?

Hans_Schmidt - Today at 2:08 PM

Yes I sent it to Tron and blondfrogs. Thanks.

[Dev] Blondfrogs - Today at 2:08 PM

I got hans address, and updated the wiki accordingly

RavencoinDev - Today at 2:09 PM

Nice! thanks guys, we'll get that sent out today.

brianmct - Today at 2:09 PM

Wow that's a lot of RVN!

Hans_Schmidt - Today at 2:09 PM

The next one is proving harder to find. That is a good thing 📷

[Dev] Blondfrogs - Today at 2:09 PM

Please @Scotty and @Hans_Schmidt look at the wiki, and make sure the address next to the issues you created is the correct address where you would like payment.(edited)

MSFTserver-mine more @ MinerMore - Today at 2:09 PM

just a heads up im renaming this channel to just development meetings

RavencoinDev - Today at 2:09 PM

We feel it's worth the amount for sure to find and fix those type of issues.

brianmct - Today at 2:10 PM

Probably shouldn't keep the addresses on the wiki, since it's publicly editable?

RavencoinDev - Today at 2:10 PM

@MSFTserver-mine more @ MinerMore okay

[Dev] Blondfrogs - Today at 2:11 PM

We will look into the github wiki permissionsand verify addresses before sending payment

RavencoinDev - Today at 2:11 PM

Thats a good point, and reach out to the individuals directly to ensure it's their correct address.

brianmct - Today at 2:12 PM

Actually it's not publicly editable. My bad. Still good to confirm directly though

RavencoinDev - Today at 2:12 PM

Yes

brianmct - Today at 2:12 PM

Probably have people put their address on the issue when reporting it

[Dev] Blondfrogs - Today at 2:12 PM

^^

brianmct - Today at 2:12 PM

Don't want any MITM attacks :P

RavencoinDev - Today at 2:13 PM

No we don't.

Chatturga - Today at 2:13 PM

Putting a public address out there is asking to get sent certain asset tokens when it goes live. 📷📷1

RavencoinDev - Today at 2:13 PM

Any questions about the issues that were found thus far?

Hans_Schmidt - Today at 2:14 PM

I verified that my address is correct.

[Dev] Blondfrogs - Today at 2:14 PM

Thanks

Hans_Schmidt - Today at 2:15 PM

Will you send a dust send first to verify (for bitcoin we do that as standard procedure for large amounts)

[Dev] Blondfrogs - Today at 2:15 PM

Yes, that is the process we follow also

Hans_Schmidt - Today at 2:15 PM

sounds good

RavencoinDev - Today at 2:16 PM

Just an FYI some of the developers were at the Free State Blockchain conference last week.We also spoke at the MIT Business schoolIt was great to see our community members there!

UserJonPizza™FlyToTheNorthRaven - Today at 2:17 PM

Are you guys 100% on the 31st? Ik prob been asked a million times but...

RavencoinDev - Today at 2:18 PM

Thanks to all that helped with the conference.📷1

[Dev] Blondfrogs - Today at 2:18 PM

The current code base will start voting on the 31st.

Chatturga - Today at 2:18 PM

Yes Its in the code.

RavencoinDev - Today at 2:18 PM

Any other questions about the Bug Bounty?

Hans_Schmidt - Today at 2:19 PM

What's the plan for next formal release?

[Dev] Blondfrogs - Today at 2:20 PM

Should be early next week, we are planning a 2.1.1 release, with the latest bug fixes in it.We thought we would give it a couple more days to see if any additional bugs are found.

RavencoinDev - Today at 2:21 PM

Agreed, there will be one more binary release before the end of the month.

[Master] Roshii - Today at 2:21 PM

Sorry late again

Hans_Schmidt - Today at 2:21 PM

I'm not pushing for the release, just asking. I prefer to have a few days to see if I can get my next attack attempt to work

SpyderDev - Today at 2:22 PM

@[Master] Roshii - were your ears burning?

[Dev] Blondfrogs - Today at 2:22 PM

Yep. You got it, keep attacking the chain!

RavencoinDev - Today at 2:23 PM

Yes please we would encourage everybody to help us find additional chain splitting or consensus defects.Other defects are also welcome, just not part of the bounty at this point.

Hans_Schmidt - Today at 2:24 PM

It would be helpful to know if someone is methodically verifying that the fixes work and also cover the minor variations, because I am not doing that.

[Dev] Blondfrogs - Today at 2:25 PM

Yes. I am personally verifying all bug fixes, and so are the other developers

SpyderDev - Today at 2:25 PM

We are also creatimg tests for them.

Hans_Schmidt - Today at 2:25 PM

Like I payed unique asset creation into the wrong burn address. But there are other variations. Your fix looks like it covers it all.

[Dev] Blondfrogs - Today at 2:26 PM

That is correct. We appreciate the bugs found and expand off of them to fix all other small variations of them.

Hans_Schmidt - Today at 2:26 PM

Great. I focus on new angles.

[Dev] Blondfrogs - Today at 2:26 PM

Prefect!

SpyderDev - Today at 2:26 PM

Please

Chatturga - Today at 2:27 PM

test 

RavencoinDev - Today at 2:27 PM

@Tron isn't able to be here but he wanted me to share this.
Hi All. I’m sorry I’m not able to make it to this development discussion. I’ve been invited to be on a Cryptocurrency and ICO/STO panel at the Federal Bar Council Fall Retreat. I've been informed that many of the attendees are judges from the Second Circuit Court of Appeals which is the Circuit Court for the state of NY. These presidentially appointed judges are just below the US Supreme Court and before whom the SEC and CFTC would be mere litigants. I’m on the panel with some heavyweight crypto and securities attorneys and my role will be talking primarily about the technology (blockchain, tokenized assets, smart contracts, etc.) while allowing the other distinguished panelists to address the legal aspects of this new technology. This is an amazing opportunity to introduce the audience to the best aspects of crypto-currencies and crypto-assets.

Pathfinder - Today at 2:28 PM

wow that's awesome

SpyderDev - Today at 2:28 PM

We are all hoping @Tron will not get arrested.

mapple - Today at 2:28 PM

yesand yes to the not arrested :))

RavencoinDev - Today at 2:29 PM

I told him the mask thing was probably a bad idea for that event...

Hans_Schmidt - Today at 2:29 PM

The Raven mask or the Guy Falkes?

RavencoinDev - Today at 2:29 PM

We need a Tron with judges Meme @PathfinderYes to both.

Skan - Today at 2:29 PM

ITS A TRAP

RavencoinDev - Today at 2:30 PM

LOL

Hans_Schmidt - Today at 2:30 PM

A Tron Trap?

mapple - Today at 2:30 PM

i was asked on telegram a few days ago about timeframes for all phases (currently announced) to be completed - are there estimates I've missed?I've properly looked through githubi've not lol

RavencoinDev - Today at 2:31 PM

We are hoping to complete the remaining phases by the end of Q1 but have provided no hard dates.

mapple - Today at 2:32 PM

OK - so march 2019 estimate if anyone asks again would be fair at the moment

RavencoinDev - Today at 2:33 PM

One of the topics I would like to cover for all our web developers is the ravencoin.com website.

gwrg - Today at 2:33 PM

Does it include Phase 7 which was added recently?

RavencoinDev - Today at 2:34 PM

That's not been fully thought through to this point so it's not likely.I wanted to make sure you all knew that Ravencoin.com is a community website, the source is posted and web developers are free to submit pull requests to make changes.

Vincent - Today at 2:35 PM

Chatturga had mentioned a plan to somehow modify the asset creation cost in the future...is that part of the qtr 1 plan?

RavencoinDev - Today at 2:36 PM

We'll be watching closely how the asset creation and RVN burn goes once it goes live.

Chatturga - Today at 2:37 PM

I did say that the rate is 500 RVN for now so that actual data can be gathered, which can then be applied to proposed changes. Speculative data just isnt enough.(edited)

RavencoinDev - Today at 2:37 PM

Anywho... The source for the Website is at https://github.com/RavenProject/ravenproject.github.ioGitHubRavenProject/ravenproject.github.ioRaven Project Website. Contribute to RavenProject/ravenproject.github.io development by creating an account on GitHub.📷

Pathfinder - Today at 2:38 PM

Tron's in there. Just have to look hard (like finding Waldo)

RavencoinDev - Today at 2:38 PM

@Pathfinder You are the best, I'm just saying....

Vincent - Today at 2:38 PM

i understand but pure economics will go into play. i will not harp on it here...there is plenty of time for this

Skan - Today at 2:38 PM

Ok good to know @ website, will spread that info

Vincent - Today at 2:38 PM

obvious my soapbox

RavencoinDev - Today at 2:39 PM

Thanks Skan!📷1Any questions about Ravencoin.com?

Hans_Schmidt - Today at 2:40 PM

I come to these meetings for @Pathfinder memes(edited)

RavencoinDev - Today at 2:40 PM

SO DO I!If I say no will you delete your post?(edited)📷Actually, if we don't have any further questions about the website that would be a great topic.

RavencoinDev - Today at 2:43 PM

@[Master] Roshii has been hard at work adding asset support to the mobile wallets.📷3You'll be able to see, transfer, receive assets.You'll also be able to create them right on your phone.

mapple - Today at 2:44 PM

awesome for small business use cases

Vincent - Today at 2:45 PM

will that only include RVN created assets or other currencies as well?

RavencoinDev - Today at 2:46 PM

The RVN wallets only support RVN and soon will support RVN assets.📷2Agreed!Any other questions about Mobile support?

russ - Today at 2:48 PM

any web wallets that support assets yet?

RavencoinDev - Today at 2:48 PM

That's a good question!

Chatturga - Today at 2:49 PM

@traysi -[MM Sysop]- Might be able to answer that.

Pathfinder - Today at 2:49 PM

https://i.imgflip.com/2kifzg.jpg📷

RavencoinDev - Today at 2:49 PM

That's amazing.I think Pathfinder could get paid to make memes for a company...@Under Has done some great work migrating web based bitcoin tools to Raven.I would love to see a web dev kit that allowed web/mobile developers to easily incorporate Raven into their projects.

SpyderDev - Today at 2:51 PM

When is the meme bounty program?

Hans_Schmidt - Today at 2:51 PM

Just wondering- is anyone tracking use of post-2.04 client use on the mainnet? It would be good to know if the non-asset stuff is continuing to work without issues on main.

[Master] Roshii - Today at 2:52 PM

@RavencoinDev I have some ideas for mobile integration kit

[Dev] Blondfrogs - Today at 2:52 PM

Everything seems to be in order on Mainnet.

RavencoinDev - Today at 2:52 PM

Awesome @[Master] RoshiiLet's open it up for General Q&A for the last 10 minutes. Anybody have a question they have been dying to ask?

Under - Today at 2:53 PM

I’d really like to know about the build system.The solution I use is pretty reliable.

cade - Today at 2:53 PM

What would you like to know about it?

Under - Today at 2:54 PM

I’d be glad to train you up on mine

RavencoinDev - Today at 2:54 PM

We are working to incorporate the work that you have put in there. Still struggling with the Mac build part of it.

Hans_Schmidt - Today at 2:54 PM

Do you track wallet version usage on main. Any idea how many people are using newer versions?

cade - Today at 2:54 PM

The current build system we're using is based on what you've doneJust modified to fit into our CI process

[Dev] Blondfrogs - Today at 2:55 PM

@Hans_Schmidt We don't have a rolling tally but you can use the explores to view node versions.

RavencoinDev - Today at 2:55 PM

We do check what's being run on the network periodically but don't have a dashboard type view into the version data.

Vincent - Today at 2:55 PM

is the burn rate going to be tracked and charted on the asset explorer?

Under - Today at 2:55 PM

Rather than incorporating it, it vanilla in a vanilla Ubuntu 18 box works pretty well. CI like Travis could run on a fully gitian build, which I’m glad to work on too

RavencoinDev - Today at 2:56 PM

@Vincent There was talk of creating an RPC call that would show how much has been burned and for what purpose.Anybody want to take a shot at writing that?

Under - Today at 2:56 PM

I’m in the process !Lol

Vincent - Today at 2:56 PM

be a great stat to watch

russ - Today at 2:56 PM

http://ravencoin.asset-explorer.net/stats @Vincentburn and creation rate

Vincent - Today at 2:56 PM

nice

RavencoinDev - Today at 2:57 PM

Sweet, thanks @russ

russ - Today at 2:57 PM

@Scotty made it📷1top notch

cade - Today at 2:58 PM

@Under We have processes and tools that are in use within our organization and we leverage those tools for all of our projects. We have taken the awesome work you've done and tailored it to fit within our toolsets.📷2

Under - Today at 2:59 PM

I can understand that, but I’d counter that the process I describe is simply a copy of bitcoins and allows for it to be replicated in a larger community of developer outside of the Medici teamIt makes the build process trustless and decentralized if it can be replicated by anyone.But I get why you have your ways of doing it.

Hans_Schmidt - Today at 3:00 PM

If you drop the burn address into the web explorer, it tells you how much went there.

Vincent - Today at 3:00 PM

charts are nicer📷2📷1

RavencoinDev - Today at 3:01 PM

I would like a burned endpoint that coinmarketcap can easily call to use in their circulating supply metric.

Vincent - Today at 3:01 PM

burn and rewards can only go one way.... 📷

RavencoinDev - Today at 3:02 PM

Alright, thank you all for being here today. Thank you for your support and for all your effort on Ravencoin platform!

Neo-Geo - Today at 3:02 PM

While we are aware of the dev team’s commitment to ASIC resistance, are there any assurances that RVN dev will find a solution to stay GPU exclusive for optimal decentralization? Monero’s commitment to fork every 6 months (currently on CryptoNightV8) has been wildly successful in keeping AMD’s cards pointing predominantly at their network. RVN is quickly replacing Ethereum as the defacto coin to mine for Nvidia owners (the world’s most popular video card), but the rise of FPGAs can ruin the incentive for GPU miners and lead to hash centralization.📷2

Vincent - Today at 3:02 PM

as a noob...glad to be part of this...great job by all

cade - Today at 3:03 PM

@Under We will be releasing our build process to the community

RavencoinDev - Today at 3:03 PM

Yes @Neo-Geo we are committed to ASIC resistance and we are watching Monero closely.Thanks again everybody. Now go find some BUGS!

Under - Today at 3:04 PM

Cool thanks guys

[Dev] Blondfrogs - Today at 3:04 PM

BTW. QT wallet GUI update is coming. hahahah. have a good day everyone📷1

IRC Log from Ravencoin Open Developer Meeting - Aug 10, 2018

[16:01] <@Wolfsokta> Todays topics: DGW implementation, segfault, Q&A, feedback on IRC
[16:01] <@Wolfsokta> Just to set the stage here, this is a developer meeting where developers that have contributed source code to the Ravencoin project can meet and chat about items they are working on. Please be respectful to one another. For the sake of staying on target, please limit interactions to questions and comments on code or projects that you are working on. Any time left over at the end can be opened up for general Q&A.
[16:02] <@Wolfsokta> FYI - I'm RavencoinDev, and lets get started.
[16:03] <@Wolfsokta> @Tron, can you talk about where we are at with DGW on testnet and mainnet?
[16:03] <@Tron> Sure.
[16:03] can someone volunteer to take notes and post also?
[16:03] <@Tron> We are building binaries that will activate DGW-180 at block 338778
[16:04] <@Tron> It looks back 180 blocks to calculate the diff.
[16:04] I will copy the text from the meeting into a file that can be archived later. I can also make summary notes after like BTC core does.
[16:04] I'll save a log of the whole meeting and can post it on the subreddit thread.
[16:04] <@Wolfsokta> We have setup testnet4 in order to test the new binaries.
[16:04] great
[16:05] <@Wolfsokta> We plan to release the binaries later today.
[16:05] @Tron have you looked into the timestamp attack concerns of DGW?
[16:05] https://github.com/zawy12/difficulty-algorithms/issues/30
[16:06] <@Tron> Yes. And for that reason, we've tightened up the timestamps that will be accepted for valid blocks.
[16:06] <@Tron> Moved from 2h to 12 minutes.
[16:06] nice
[16:06] Oh wow okay
[16:06] <@Tron> Its also the reason we went from 60 blocks (lookback) to 180 blocks.
[16:07] why would 2h ever be acceptable? lol
[16:07] 2h was originally used for daylight savings shenanigans I believe
[16:07] <@Tron> It was from bitcoin, and it factors in clock skew, and variance in finding blocks on 10 minute intervals, and block propagation time.
[16:07] makes sense
[16:08] what about the segmentation fault when reindexing?
[16:08] any fix yet?
[16:08] @Tron 12 minutes seems to be pretty small window for clock skew
[16:08] I assume it was chosen due to 1/10th scaling from BTC?
[16:09] <@Wolfsokta> Not yet ruski, we'll cover that in a bit.
[16:09] <@Tron> We did divide existing by 10.
[16:10] <@Wolfsokta> Any further questions about DGW on testnet or on mainnet?
[16:10] What block is it activating on mainnet?
[16:10] <@Wolfsokta> 338778
[16:11] And will there be the need to update binaries twice (for DGW fork and asset layer fork)?
[16:11] <@Tron> We are activating DGW by block height because headers sync first, and the BIP9 activation flag sets a flag, and we need to look at either block height or version to know which diff algo.
[16:11] <@Wolfsokta> Calculated to be near the end of the month so we have some time with DGW on testnet.
[16:11] Someone on discord asked this a while back, but why Was DGW chosen over something like digishield or anyother algo
[16:11] <@Tron> And block version can be changed (tampering) and still make it on the chain.
[16:12] Binaries will need to be updated as more asset layer stuff get completed and tested. Not by the end of the month though.
[16:12] <@Tron> We looked at DGW and LWMA. LWMA has a lot of constants that must be tuned right.
[16:13] <@Tron> We were impressed with the amount of work on LWMA to analyze how it responds, but it wasn't straightforward to understand the nuances of how/why it works.
[16:13] zawy was in the #development channel on Discord. He's an expert on DAAs. I'm sure he would help with tuning LWMA if you asked.
[16:14] <@Tron> Either will be much better that what we have. Even at the extremes, it will adjust smoothly.
[16:14] Are there any issues or comments on the DGW code that should be addressed?
[16:14] @devs in general
[16:15] <@Wolfsokta> Thanks @brianmct, we did look extensively at the DGW code to ensure we weren't going to see the same issues that happened to Verge.
[16:16] so i guess you would have to make way more blocks with false timestamps to be able to exploit our version of dgw right?
[16:16] because of the 12 minute timestamp thing?
[16:16] <@Wolfsokta> With X16R, and with the changes Tron talked about we feel confident that this will address the swings without being able to be exploited.
[16:17] nice
[16:17] @russki Yeah, pretty much.
[16:17] verge is a different type of situation - but overall asics and mining are a risk always
[16:18] <@Wolfsokta> Okay, anything else on the difficulty targeting change?
[16:19] <@Wolfsokta> Cool, blondfrogs wanted to talk about subassets that were added.
[16:19] ooh yeah i saw those github commits
[16:19] looking good
[16:19] We also want to let everyone know that you can now create sub assets with the new binaries that will be posted soon. You can create these subassets using the issue rpc call. Qt will be built shortly. This will allow users to make an asset PARENT
[16:20] <@Wolfsokta> Basic overview. If you own an asset you can create sub-assets by including a '/
[16:20] nice
[16:20] And then make any of the following PARENT/A PARENT/B .... PARENT/Z
[16:20] <@Tron> We'll post a FAQ on assets later today.
[16:21] <@Wolfsokta> And it only is 100 Raven for a subasset
[16:21] on testnetv4 it still says asset activation status: waiting
[16:21] why?
[16:21] <@Tron> Yep, it needs to be voted in.
[16:21] <@Wolfsokta> We wanted to test the BIP9 activation process again as well. The more testing the better.
[16:21] We wanted to make sure that we follow the same process the Mainnet is going to go through.
[16:21] ok nice
[16:22] <@Wolfsokta> Any questions about subassets?
[16:23] are they unique?
[16:23] <@Tron> No
[16:23] <@Wolfsokta> Yes, they behave the same way as a normal asset, just live under an owned asset.
[16:23] <@Tron> Maybe I misunderstood the question. Unique with parent.
[16:23] Each subasset can have their own number issued? So PARENT/A can have 1,000 and PARENT/B can be 50?
[16:23] yes
[16:23] oooh ok that makes more sense
[16:23] <@Wolfsokta> Exactly thanks traysi
[16:24] <@Tron> And, not the same thing as "Unique Assets"
[16:24] <@Wolfsokta> The individual unique asset support is included in an upcoming phase.
[16:25] Moving onto the Segfault issue ----------------------->>>>>>>>>>> SEGFAULT
[16:25] Are we able to changes the properties of subassets after they have been created? Or is something like that specified when creating them?
[16:25] <@Tron> Yes
[16:25] can sub-assets be reassigned to other addresses while retaining control of the parent asset elsewhere?
[16:25] So basically it has all the features of a normal asset, but live under an asset's top-level namespace?
[16:25] satoshi corbie @russkidooski
[16:25] So basically it has all the features of a normal asset, but live under an asset's top-level namespace?
[16:26] <@Tron> Sub-assets are identical to assets after creation.
[16:26] <@Tron> Just cheaper to create, and in your "owned" namespace.
[16:26] Okay cool
[16:26] will subassets eventually have a unqiue tag? eg ASSET/SUB:1
[16:26] We have found an issue with our testnet binaries and are still looking to the issue. The issue presents itself when a user performs a reindexing of the chain. We think we have pinpointed the where the problem is and are currently working a fix. This fix will be out shortly.
[16:26] plan is to make default reissue=true and units=0 and allow increase in units on reissue
[16:26] How much is it going to be for a sub-asset?
[16:27] 100
[16:27] <@Wolfsokta> Okay, let's now focus on the SegFault issue that was discovered by Under.
[16:28] do you know what the issue was?
[16:28] <@Wolfsokta> It seems to be a build problem with the boost library.
[16:28] Still looking into though. :)
[16:29] <@Wolfsokta> We have been able to reproduce it on linux internally with 2.0.3
[16:29] yea i get the same issue on windows 10
[16:30] I saw a Bitcoin thread a while back about the seg fault error. I had it because I had conflicting versions of BDB
[16:30] static compiled on ubuntu 18.04
[16:30] <@Wolfsokta> We really appreciate you guys pulling down master and helping test.
[16:30] @Trap we will look into that also
[16:30] no problem, im just curious lol
[16:32] <@Wolfsokta> We haven't been able to build a windows version that doesn't have the segfault issue.
[16:32] <@Tron> We're dropping Windows support ;)
[16:32] lol
[16:33] Just finished setting up a new Windows test environment so we can test and validate the solution as we are working on it.
[16:33] The bdb issue is a known issue that has been around for some time. We are pretty certain it is a boost library issue, and are working quickly to get a windows build that fixes the issue.
[16:34] what did you guys do to fix the linux version?
[16:34] Once we have binaries for all supported platforms ready, hopefully tonight. No promises. We will make an announcement
[16:34] The issue has been fixed on Linux and Mac though?
[16:34] (oops sorry already answered)
[16:34] <@Wolfsokta> If anybody else gets there first with Windows please let us know what you found.
[16:34] Built the binairies on a Ubuntu 16.04 box.
[16:34] that was it?
[16:35] Yeah, we think so. 16.04 has boost 1.58 which seems to fix the issue. The build on 18.04 use boost 1.67 which seems to cause the issue.
[16:35] is there a boost 1.58 repo on 18.04?
[16:35] 18.04 used 1.65***
[16:36] I've built with boost 1.68 on arch Linux
[16:36] It worked
[16:37] wallet 2.0.x?
[16:37] @Trap, the issue is when -reindex is used.
[16:37] Oh sorry my bad
[16:37] Wallet 2.0.3
[16:38] <@Wolfsokta> For those that joined late we're discussing https://github.com/RavenProject/Ravencoin/issues/208
[16:38] 1 sec im going to boot into ubuntu and try compiling with 1.58 on 18.04
[16:39] Any other questions pertaining to the segfault?
[16:40] <@Wolfsokta> Alright, thanks everybody. Before we start the Q&A I would like to get some quick feedback on using IRC for this meeting.
[16:41] If we're going to use IRC we should take some measures to at least hide people's IPs when they join
[16:42] Yea. It is very hard to read this back.
[16:42] Also no message history
[16:42] If you disconnect and reconnect
[16:42] <@Tron> I'll throw in a vote for Discord.
[16:43] <@Wolfsokta> If you use a decent IRC client instead of the website it's not bad.
[16:43] Some of us used a VPN before we connected to IRC
[16:43] If needed we can restrict channel to Developer roles, etc for the developer meeting and open it up for general Q&A
[16:43] https://www.strawpoll.me/16247952
[16:43] poll
[16:43] Make a discord when only mods can submit links
[16:43] Where*
[16:45] Discord won the poll 5 to 2
[16:45] <@Wolfsokta> There are also a lot of IRC tools that can be used to track the meetings.
[16:45] we know
[16:46] <@Wolfsokta> We also want any developer to be able to speak.
[16:48] <@Wolfsokta> We're open to try Discord next week.
[16:48] <[kai]> perhaps you could even get a feed from this irc to discord?
[16:49] <[kai]> a feed would enable discordians to view the chat, but only contribute if they take the extra steps to come here.
[16:49] <@Wolfsokta> That's a good idea kai... Has anybody seen that working?
[16:50] <[kai]> https://github.com/reactiflux/discord-irc
[16:50] <[kai]> im sure you could make this a one way deal.
[16:51] <@Wolfsokta> I like that idea, let's try that for next week. So we'll meet here in IRC again, but it should be broadcast to Discord.
[16:53] <@Wolfsokta> Okay, we'll go with IRC next week with the broadcast to discord and re-visit for next week.
[16:54] <@Wolfsokta> Okay, let's do open Q&A for the next few mins.
[16:54] <[kai]> just a quickey, more for my curioisty, did you look at digishield?
[16:54] <[kai]> DGW solution seems solid.
[16:55] <[kai]> was just curious if it was one of the four solutions you looked at.
[16:55] <@Wolfsokta> Tron is answering... Any others Q?
[16:55] <@Tron> We briefly looked at Digishield, but our analysis was between DGW and LWMA.
[16:55] <[kai]> right on.
[16:56] <[kai]> cheers guys, see you next time.
[16:56] OPen the gates for the last 4 minutes for any other questions?
[16:58] <@Wolfsokta> Alright, thank you all for being here today and please join the development effort with us. If you have an idea, or a fix for an issue write it up and submit a pull request.
[16:59] <@Wolfsokta> Thanks again for all those that have contributed their time and effort to make Ravencoin successful. We have the BEST community.
[16:59] ^
6:59] You devs are pretty cool
[16:59] did the burn get discussed?
[16:59] <@Wolfsokta> Special thanks to Bruce, really glad you could make it with the short notice.
[17:00] <@Tron> Thanks everyone!
