Anonymity & Cryptocurrency: A Few Tips On How To Keep Your Privacy
Unfortunately, anonymity isn’t something that you think about as being valuable. But as Edward Snowden points out in one of his interviews, “Arguing that you don’t care about the right to privacy because you have nothing to hide is no different than saying you don’t care about free speech because you have nothing to say.” https://preview.redd.it/a2t5wii1wnj41.png?width=1024&format=png&auto=webp&s=df6889e510a2a0b231614636d0b6c1ac7be7e2c4 Many people are going up against online anonymity, mainly because it has the potential to enable and encourage undesirable behavior or illegal activity. State institutions and corporations are trying to limit the ability to use networks without authorization, allegedly in an attempt to increase security. Meanwhile, there is no doubt that private information that falls into the wrong hands can be used for mean purposes in many ways. Dozens of examples truly highlight the need for online anonymity today. Without it, people’s lives can easily be ruined forever. Financial and personal freedom are the main reasons why people started using cryptocurrencies. But using Bitcoin itself can not guaranty anonymity. They are not linked to a person or identity, so the name, e-mail or physical address can’t be found in the transaction. But public addresses we use publically recorded on the blockchain, so a person can be tracked down using this information and ID. Here are some methods to keep your identity safe. Use logless VPN Virtual Private Network encrypts all of your Internet traffic and routes it through multiple servers at different locations before arriving at the final location. Using a VPN is one of the simplest ways to cover your digital tracks. Logless VPN services don’t store the history of your activities, some of them provide one IP address for several users, making it difficult to isolate one person among them. It is highly recommended to avoid US/UK-based VPN services due to strict surveillance regimes in these countries. Also, you should keep in mind that some exchangers’ security systems treating logging into an account with numerous different country IPs as suspicious which can lead to blocking your account. Register a separate email Never use personal or working email for the needs of the crypto. If hackers gain access to it that can ruin your life in many aspects at once. A significant advantage will be the use of burner emails such as Guerrilla Mail and Temp Mail, or highly protected services like ProtonMail or Tutanota. Don’t forget about common security rules such as using a strong password that contains different case letters, numbers and symbols. Keeping passwords and keys on your devices is definitely not safe, better write it down in an old-fashioned pen-paper way. Create new blockchain address Make new addresses for every single transaction you make. More than half of all transactions in the BTC network go through wallets that have been in use at least once. Over time this practice will build up a list of transactions associated with one wallet. Using some manipulations those transactions could be easily associated with a real-world identity as well as your wallet could be simply hacked and robbed. Avoid KYC and AML using services Know Your Client is a policy used by many companies in which each client is required to provide credentials such as ID documents to use a company’s service. Anti-Money Laundry consists of KYC procedures and ongoing risk assessment and monitoring of transactions. Such actions are implemented in the best interest of protecting users of cryptocurrency platforms but left no chance to stay anonymous. Nowadays most of the crypto markets and exchanges require passing identity verification due to the growing control from the state institutions. However, there are some that allow you to remain anonymous unless you are withdrawing a large amount (Binance, Bitfinex, KuCoin, etc.). In such circumstances, decentralized exchanges seem like a good option. Use Anonymity-Centric Cryptocurrencies As mentioned earlier, blockchain analysis based on knowledge of the amount and time of the sent transaction allows hackers to attack user’s wallets and gain access to their data. As a reaction to this was developing coins with anonymity as the main priority. At the moment, Monero is the most popular of the anonymity-centric cryptocurrencies. It has a complex of cryptographical tools for obfuscating traces of the original transaction. Its RingCT Protocol hides the sender, recipient and transfers amounts. After the transaction is completed, it is signed and receives a time-stamp using a ring signature, where collected group’s public keys, but the private key of the specific sender is not displayed. Another private currency’s Dash work is based on the CoinJoin technology. The idea of the process is very simple: several transactions are mixed into one, so it is impossible to determine what amounts were transferred and by whom. Zcash currency uses the Zero-Knowledge Proof commitment scheme to validate transactions without revealing information about them. Protocol, called Zk-SNARKs, comprises three algorithms that generate proof and verification keys, calculate the proof and verify the authenticity of the secret information. The obvious drawback of this mechanism is extremely massive complex calculations that require enormous capacity. Even if complete anonymity seems not possible, following the above rules will help you avoid a lot of trouble. You should be extra meticulous in the process of choosing currency and an exchanger, keeping in mind where and what personal information you provide.

ExpressVPN: Ranked #1 out of 100 VPNs that we tested ExpressVPN is one of the most popular VPN services on the market, but is it really the “#1 trusted leader in VPN” as it claims to be? We put ExpressVPN through rigorous testing and in this review we’ll tell you if it’s honestly the top VPN of 2019, and we’ll answer common questions like: Is ExpressVPN really that fast? Is it legit and safe to use? Does ExpressVPN unblock Netflix? Does ExpressVPN allow torrenting? How much does ExpressVPN cost? But before we jump in, here’s a quick overview of ExpressVPN’s pros and cons: Pros Cons Exceptionally fast same-country speeds Works with Netflix, BBC iPlayer & more Safe, fast & unrestricted torrenting/P2P Strong logging policy & no IP, DNS, WebRTC leaks User-friendly apps for PC, Mac, iOS, & Android Great server network across 94 countries More expensive than some rivals Fire Stick TV app needs updating Works with Netflix, BBC iPlayer, HBO, Hulu, Amazon Prime Video, Sky, SlingTV, Torrenting, Kodi Available on Windows Mac Ios Android Linux Price from $6.67/mo That’s just a few highlights of what’s to come. Keep reading to see if ExpressVPN is the right VPN for you, starting with how fast it is. Speed & Reliability One of the fastest VPNs we've tested ExpressVPN is one of the fastest VPN services we’ve tested – it’s extremely quick and responsive. ExpressVPN is also remarkably reliable and consistent, whether you’re connecting to a local server, or one on the other side of the world. It’s speed is also very impressive in high censorship countries like China, where most other VPN services struggle to even connect. Use the table below to see how ExpressVPN speeds fare against its top-scoring rivals in 11 locations around the world.

From our location in the UK, we tested average speeds connecting out to various locations worldwide while connected to ExpressVPN: USA: 77Mbps (download) & 40Mbps (upload) Germany: 79Mbps (download) & 66Mbps (upload) Singapore: 73Mbps (download) & 22Mbps (upload) Australia: 59Mbps (download) & 1Mbps (upload) Server Locations 3,000+ servers across 160 locations Globe with a blue flag 94 Countries Image of a city landscape 160 Cities Image of a pink marker 3,000+ IP Addresses See all Server Locations ExpressVPN operates more than 3,000 VPN servers across the world, spread evenly over every continent (excluding Antarctica). No matter where you’re located you should have no trouble finding an ExpressVPN server near you. 3,000 servers is one of the widest ranges of servers we’ve seen from any VPN service, and the ExpressVPN website even lists which VPN security protocols are available in each location (either country or city). ExpressVPN provides city-level servers in a number of locations, too: US UK Australia Brazil India Singapore Netherlands Germany France Italy Spain ExpressVPN’s 27 different city-level locations in the US and in four in Australia are some of the highest totals we’ve seen. Streaming & Torrenting Instantly unlocks Netflix, BBC iPlayer and torrenting ExpressVPN easily unlocks Netflix through almost all of its US-based VPN servers (apart from New York), even if it doesn’t offer servers dedicated to streaming like some of the other top-tier VPN services like CyberGhost. ExpressVPN’s Isle of Man and Jersey servers work well with UK Netflix, while most UK servers will unlock BBC iPlayer (although customer support informed us it will only work if you’re located outside of the UK). ExpressVPN is also a popular choice with viewers of a whole range of other big streaming services. Plenty of subscribers enjoy using ExpressVPN with: Amazon Prime Video Hulu HBO Sling TV Sky Now TV PlayStation Vue The following ExpressVPN servers worked for unlocking Netflix: USA (New Jersey, Washington DC, San Francisco) Canada (Montreal, Toronto, Vancouver) UK (Isle of Man, Jersey) Torrenting Torrenting and any type of P2P traffic is allowed on all ExpressVPN servers, resulting in less congestion and faster speeds as a bonus. ExpressVPN registered fast speeds both downloading and uploading, which is fundamental for a good torrenting and P2P experience. ExpressVPN also works for those looking to stream via Kodi or similar media player apps. Privacy and security-wise, ExpressVPN’s kill switch works extremely well (should your VPN connection drop at any point) and when we tested ExpressVPN for IP or DNS leaks, we found zero. What’s more, ExpressVPN doesn’t keep any activity logs. You can read more about all of this below. Bypassing Censorship Works in China, UAE and more ExpressVPN works in China, bypassing Chinese censorship with ease, largely thanks to the company devoting significant resources into outsmarting the censors. That is why ExpressVPN is our best VPN for China. If you have protocol selection switched to Automatic, ExpressVPN’s proprietary obfuscation security protocols are activated, which are very effective in beating aggressive state-level censors. These obfuscation protocols ensure that its VPN apps easily beat even the most aggressive of blocks in countries like Turkey, Saudi Arabia and Iran. Platforms & Devices Works with all popular devices Apps Windows Logo Windows Mac Logo Mac iOS Logo iOS Android Logo Android Linux Logo Linux Router Logo Router ExpressVPN supports just about any operating system or device out there – Microsoft Windows, MacOS, iOS and Android – with installation instructions given for each one. Where ExpressVPN doesn’t have a native dedicated VPN app, you have access to a walkthrough on the ExpressVPN website to show you how to set up a workaround. Games Consoles & Streaming Devices AppleTV Logo AppleTV Amazon Fire TV Logo Amazon Fire TV Chromecast Logo Chromecast Nintendo Logo Nintendo PlayStation Logo PlayStation Roku Logo Roku Xbox Logo Xbox ExpressVPN is one of the best VPN services for Amazon’s Fire TV Stick, although it is not our number one choice. Why is not our top pick? Well, ExpressVPN may have been one of the first VPN providers to roll out a Fire TV Stick app, and it works fine, but it’s grown to look out-dated and lacks some of the features that we’ve enjoyed in more recent Fire TV Stick VPN apps. If you own a Fire TV Stick and want to use a VPN app with it, take a look at our top VPN picks for Amazon Fire TV and Fire TV Stick. If you want to run ExpressVPN on other streaming devices or games consoles, you’ll need to install ExpressVPN at router level, or you can piggyback off of the VPN connection from another device, like your PC or Mac. Browser Extensions Chrome Logo Chrome Firefox Logo Firefox Safari Logo Safari ExpressVPN provides full VPN browser extensions for Google Chrome, Mozilla Firefox, and Safari. Most of the VPN browser add-ons we see from other VPN providers are proxies pretending to be full VPNs, but ExpressVPN’s extensions are the real deal. You can choose your server location from within the browser extension, which is a really neat solution. Thanks to a recent update you can now use ExpressVPN on five different devices at once, too. Encryption & Security Leader in security, with strong extras like a VPN kill switch & obfuscation protocols Protocol IKEv2/IPSec L2TP/IPSec OpenVPN (TCP/UDP) PPTP SSTP Encryption AES-256 Security DNS Leak Blocking First-party DNS IPV6 Leak Blocking VPN Kill Switch WebRTC Leak Blocking Advanced features Split Tunneling Please see our VPN Glossary if these terms confuse you and would like to learn more. ExpressVPN is a legitimate and extremely secure VPN service, with a multitude of standards and VPN protocols in place to keep your browsing data private and secure. If you leave the VPN protocol setting on Automatic then the ExpressVPN app will determine what is the best security protocol to use – a handy feature that’s not all that common. AES-256 encryption is widely regarded as near-unbreakable; OpenVPN, our favorite VPN protocol, is one of many available; and ExpressVPN also has the always-essential VPN kill switch, ensuring you stay protected in the event of your connection dropping. Split tunneling is yet another powerful feature that’s not all that common among VPN services. It allows you to protect your web traffic while keeping access to connected devices on your network, like your printer or Smart TV. We found ExpressVPN to be fully protected from any IP or DNS leaks, too. You can count on ExpressVPN to successfully hide your real IP address. ExpressVPN recently launched its TrustedServer feature, a proprietary technology that removes the need for local storage such as hard disks or solid state drives. Once again, ExpressVPN is leading the pack when it comes to security and privacy. Logging Policy Close to truly no-logs and away from 14-Eyes ExpressVPN doesn’t collect any personally identifiable activity logs. Here’s all the information collected by ExpressVPN’s VPN servers: Dates when connected to the VPN service Choice of VPN server location Total amount of data transferred per day That’s it. ExpressVPN maintains that this is the minimum amount of information required to be collected in order to keep the performance of its servers as strong as possible. The most important thing of all is that this data cannot be used to identify you, or what you do. All that’s possible to reveal is that you have used ExpressVPN’s service at some point. This is totally anonymous, and about as close to zero-logs as you can get. A recent report by the Center for Democracy and Technology (CDT) questioned ExpressVPN in greater detail and concluded that its servers were both “extremely difficult to compromise” and “limited in the amount of data that could be revealed” in the event that they were. ExpressVPN’s logging policy was put to the test in December 2017 when one of ExpressVPN’s Turkish VPN servers was seized and inspected by Turkish authorities investigating the assassination of Russian ambassador to Turkey, Andrei Karlov. The investigators could not find any customer connection logs. Jurisdiction ExpressVPN was founded in 2009 and is operated by Express VPN International Ltd., which is based in the British Virgin Islands and far outside of the intrusive 14-eyes surveillance alliance. That’s an excellent choice of location for a privacy-minded VPN company, as the British Virgin Islands has full sovereignty over its own data regulations. Foreign governments can still make demands for information, but ExpressVPN makes it clear that it will never share data with them and, crucially, that it doesn’t have any personally identifiable information to share in the first place. In case you’re still wondering, you’re safe with ExpressVPN.

I think my elderly aunt is getting involved in a Bitcoin mining MLM scheme. Can someone please help me identify if this business is legit?
I posted this on /antiMLM and someone suggested I post here. TL;DR at the bottom. I'm so sorry this is so long, but I am just very worried about my aunt. She just recently lost her husband to cancer. Before he passed away, he invested money in some sort of Bitcoin mining company. The transaction was facilitated by a couple that I think he had seen present the business model at a "millionaire's clubhouse" \(my aunt's words\). The idea was that they buy hardware from their company which will mine Bitcoin little by little over three years. They say that it is more stable than buying Bitcoin, which can fluctuate in price and cause you to lose money. They give you an account you can log in to so that you can check your progress. Yesterday, my aunt told my mom that she had earned money from mining and wanted to invest it in more mining hardware on my and my younger brother's behalf. She wanted my brother to come over to her house to meet the couple she had been working with so that they can explain the whole process to him. Because she is inept with technology, she was hoping that he could manage her account as well. My mom was concerned that this was a scam and begged me to accompany my brother just so there was another objective eye. I agreed and brought along my boyfriend. So I'm going to try and do my best to describe what this couple was telling us. I don't know if it was just because I was tired, but it seemed like they were trying to explain this business as confusing as possible so that we couldn't ask them anymore questions.
To be able to use the mining hardware, you must buy into a "mining pool". There are three different kinds. I think it roughly goes from $500, $700, and $1000. The cheapest one will mine very small amounts. The more expensive the pool, the more Bitcoin is mined.
If you want to be able to mine a larger amount of Bitcoin, you can buy all mining pools for one price of $3900.
This is where the MLM alarms went off: the more people buy into your pool, the more Bitcoin you earn. So to really see the best profits, you would need to recruit people. This is essentially how this couple is making money. They showed us a preview of their mining pool and my boyfriend calculated that they were making around $1000 a day \(although we're not sure if what they showed us was even real\).
So here is a list of all the sketchy things the three of us noted:
My aunt got into this whole investment while my uncle was sick with a stage 4 brain tumor. I'm worried they made these financial decisions while my uncle was not completely right of mind.
The meeting was late at night, around 10pm. They were about 30 minutes late.
The woman was the one creating the log in account for us. She said it doesn't even have to include our real names. Just a gmail that we can access.
We cannot log in to check our mining process for 30 days. Apparently that's how long it takes for them to set up the mining hardware. The actual mining hardware is in Iceland.
The United States is "not friendly" towards Bitcoin, according to the lady, so to be able to access your account you need to have a VPN on your computer. I asked them if we needed it on ours, and they said no. So I asked why my aunt needed it on hers. Apparently if you want to be able to recruit people like my aunt did, you need a different account \(which surprise, you also have to pay for!\).
The mining will go on for 3 years. Depending on the kind of pool you buy and how many people are in that pool, a certain amount of Bitcoin will be earned. Obviously the more expensive the pool and the more people you recruit, the more Bitcoin it will mine. They say that after 3 years, you could potentially have 1 full Bitcoin or more.
I asked them if my aunt was able to check on her account and the lady just responded "Your aunt has a book of usernames and passwords." When my aunt wanted to check how much her account was worth, they lady just laughed and said "You're worth enough". She did not bother to show my aunt her account, even after her insisting.
The man stayed completely silent until it was time to discuss all the "benefits" of Bitcoin and mining. He would not shut up about all the people he has recruited from all these different countries \(including our home countries too\). He also kept emphasizing how "passive" the money making process was, kept citing Forbe's magazine and the channel 11 news station regarding the huge value of Bitcoin, and bragged about being able to buy a Bentley and being close to buying his dream house. All he talked about was all the money he and his wife and other people were making from Bitcoin and my poor aunt was eating that shit up.
My aunt wanted to just buy one account for my brother and I to share, but the lady kept insisting she buy us separate ones \(including one for my boyfriend\). Luckily my aunt was dead set on just getting one.
They were asking my aunt if their meeting with her friend was set. She told them her friend was not available until 2 weeks from now and they said "No, it has to be soon. We can't wait."
I think my aunt is able to access her account. She says that she has already earned $1000 from the account that she set up in September. According to her, she has withdrawn money from there to help another aunt out with some expenses. At the end of the meeting, it turns out she couldn't even use the money she earned to buy us our own account because she has maxed out on her withdrawals \(at least, that's the impression I got from the woman. Again, she was vague\). She had to write a new check for $3900. The woman was very eager and even wrote the company name on the check for her. She also obnoxiously showed off another check that she had received from a client she had met that same day. We told our mom what we saw the next day and she was mad we didn't try to stop her. I really do feel terrible that I let her spend her money like that, but from what we saw it seemed like she was very set on this mining thing and that we couldn't have talked her out of it at that moment even if we tried. We called her today to ask if she was able to cancel the check because we didn't think the couple was very legit. She sounded angry and told us: "Well they already cashed the check. It's too late. I don't know what you've been reading but I know this works. I already earned $1000." My aunt has already tried to rope in some of my relatives on this scheme. A few were smart and saw right through the couple, and a few gave in just out of pity for my aunt. For her sake I'm hoping this will actually turn a profit, but I don't want her giving any more money to these people. I do have the URL to the mining website, but I didn't know if I am allowed to post it here. If necessary, I will PM the details to those who ask. TL:DR Is Bitcoin mining legit? My aunt has invested thousands in an MLM-type mining process that I don't completely understand or trust.
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!
