Storage space: I am using an 8 GB microSD card for the OS, and a 128 GB USB drive for data. Minimums I would recommend: 8GB SD card and 32 GB USB drive.
Reddcoin Core client version: v126.96.36.199-a8767ba-beta (most recent version at this moment). ↳ Screenshot
You need the OS; Lubuntu. Download Lubuntu (707 MB) for the Raspberry Pi: https://ubuntu-pi-flavour-maker.org/download/. It's a .torrent download, so you will need a BitTorrent client. Message me or post in this thread if you need help with this.
You need software to write the OS to the SD card. I use Etcher. Download Etcher: https://etcher.io/.
Select image: select the lubuntu-16.04.2-desktop-armhf-raspberry-pi.img.xz file.
Select drive: select your microSD card.
Plug the SD card into your Raspberry Pi and power it up.
Lubuntu should boot up.
Set up Lubuntu, connect to the internet (wired or wireless). ↳ As username, I chose "rpi3b". You will see this username throughout this whole tutorial.
Make sure date and time are correct ([Menu] > System Tools > Time and Date). ↳ Click on Unlock to make changes. I personally change Configuration to "Keep synchronized with Internet servers". ↳ Screenshot
Reboot ([Menu] > Logout > Reboot). I am connected to wifi, but have issues getting wifi to work on initial boot. A reboot solves this issue.
Make sure system is up-to-date, install never versions.
Open LXTerminal ([Menu] > System Tools > LXTerminal). ↳ Screenshot
Enter the following in LXTerminal: sudo apt update && sudo apt upgrade ↳ Screenshot
You will be asked if you really want to continue. Enter Y (yes).
Updates are being installed! Wait until it's finished.
Install programs that will be used in this tutorial.
GParted: to partition the USB drive.
Htop: to see the amount of memory (RAM) and swap that is in use.
Enter the following in LXTerminal to install these 2 programs. sudo apt install gparted && sudo apt install htop ↳ Screenshot
Create 2 partitions on the USB drive: 1) Swap partition 2) data partition (for the Reddcoin blockchain) The swap partition is necessary: The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 2 GB of 'virtual' memory by creating a swap partition.
Important: Backup your USB drive if needed. The USB drive will be formatted, so the data on the USB drive will be wiped.
Please use the USB drive solely for this purpose, do not combine it with other stuff.
Keep your USB drive plugged in, do not (randomly) plug it out.
Plug your USB drive in.
GParted will be used to create the partititons. Start GParted via LXTerminal: sudo gparted ↳ Screenshot
Apply the changes. Click on the check mark or select Edit > Apply All Operations. ↳ Screenshot ↳ Screenshot
Important: The name of the swap partition is needed later, so please write it down. Mine is /dev/sda1 (first partition on first drive (drive 'a')). ↳ Screenshot
Reboot. After the reboot, the data partition you just created should be visible on your desktop. ↳ Screenshot
The swap partition is created, so now we can enable and use it.
The swap in use can be monitored with the program Htop. Open Htop ([Menu] > System Tools > Htop) to see the 'Swp' (swap) in use. ↳ Screenshot By default, swap is not used, so 0K. ↳ Screenshot You can leave Htop open.
To enable the swap partition, open LXTerminal and enter the following commands: (Assuming /dev/sda1 is your swap partition.)
Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
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.
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.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot
To auto run on startup:
Open Default applications for LXSession ([Menu] > Preferences > Default applications for LXSession). ↳ Screenshot
In LXSessions configuration, select Autostart in the menu left.
Under Manual autostarted applications, enter vncserver-x11 and click on + Add. ↳ Screenshot ↳ Screenshot
Reboot your Raspberry Pi and check if VNC Connect is started automatically after the reboot.
When VNC Connect is running, you'll see a VNC icon on the right bottom corner. Double click the icon to open VNC Connect and to see the IP address you need to enter to connect to your Raspberry Pi. ↳ Screenshot
Cutting to the chase or how to properly evaluate privacy coins!
EDITBe aware, the moderators of cryptocurrency have SHADOW DELETED without cause the original thread. This is most likely at the request of the XMR community. Also, the Monero community continues to Vote-Brigade this thread. Originally 11-14 upvotes, and even today 5 upvotes, they make sure it stays around 1. This is manipulation.
This causes the post to appear to me, but to everyone else its been deleted. Now, why would they undertake such an underhanded tactic? End EDIT There's a lot of talk about anonymity and privacy as it relates to blockchains. Recently a report surfaced mentioning that cryptos are basically bad news for criminals: https://dailyhodl.com/2018/09/16/bitcoin-is-actually-a-money-laundering-tracking-device-that-catches-criminals-report/ TL;DR is at the bottom Why? Because they're easy to track. Once they've got a single piece of identifying info that's linked to an address (say that coinbase transfer to an exchange) then all transactions are linkable to that id. But, privacy coins are different because they obscure this history (or in some cases 'delete' it all together). However, it can be a little difficult to decide which privacy coin offers the best privacy, along with the best combination of fees, security and usability. So with no further ado, here is your simple guide to evaluating privacy coins! Like daily tx throughput is a key metric of btc/blockchain adoption and usage, privacy coins have their own 'key metric' to determine their ability to hide your tx history: the size of their anonymity set. This is basically the number of other people with which your transaction is plausibly 'mixed' so at to sever the link between your address and that coin. The greater this number is, the more difficult it is to associate a coin with your address, thus making it more private. To make this easier to understand, it helps to know the following: All privacy coins do the same thing, just in vastly different ways. What is that thing? Obscuring/removing your linkage to a coin by mixing it with a similar coin denomination from another wallet. Monero is a slight exception to this, since transaction amounts are hidden in the blockchain as well, so there's no need for denominations. Also, your coin is mixed with fake coins that aren't real, instead of coins from other wallets, but no one can tell that from the blockchain so it works.
It should be noted that in Dash, the anonymity set is the total set of each denomination. So if you send a .1 Dash privateSend transaction, the anonymity set is the set of all .1 Dash. The following only applies if you've bought up more than 70% of the masternodes, and only to transactions that are currently being mixed. Previously mixed transactions cannot be deanoned. In Dash, it depends on how many rounds you mix. Each coin is once again broken down into standard denominations like 10, 1, .1 .01 and most recently, .001 Dash. Each round involves a minimum of three different wallets. So take the number of participants and raise it to the rounds you mix-th power, and that is your minimum anonymity set. So mixing four rounds gives you a minimum anonymity set of (3 participants)4 rounds = 81. Eight rounds gives you a min set of 38 = 6,561. 16 rounds give you a min set of 316 = 43,046,721 which is currently the second largest anonymity set of all the privacy coins. Could be more if more than three wallets were involved in any single mix, which is possible. However, it could be less if the same participants are used per round, which is unlikely. This is still a HUGE anonymity set; however, its probably at least an order of magnitude less than PIVX and ZCoin unless you were to get 4-5 wallets mixing per round. Dash's anon-set is the second largest in the private coin space and is around 3x larger than PIVX's. Still, even 81 could be rightly considered overkill, especially since Considering the nature of privateSend and the random separation between 'minting' and spending, Dash is immune to timing analysis attacks. The determination of which coin to use will come down to your anonymity needs. How private do you need to be?
In PIVX, for example, ~10-20% of all pivx held in wallets is 'gathered' by the accumulator (note it never leaves your control) in a central pool of zpiv using standard denominations like 10 zpiv, 1zpiv, .1zpiv etc. This is a configurable setting in the wallet so some may wish to turn it on/off at their discretion, but recent research has shown that 24% of all PIVX held in wallets is private/zpiv, see u/turtleflax's comment below. After all of that, by using a zero-knowledge proof which cryptographically proves you owned whatever zpiv was minted from your wallet without any linking information to you, zpiv is 'sent' to your wallet and shows up with no transaction history. So the anonymity set is 10%, 24% nowadays, of all PIVX held in wallets, which is obviously huge.In Apr 2019 a vulnerability was discovered in the ZeroCoin protocol that PIVX and ZCoin both share.
Now that the issue has been confirmed, we will no longer wait for the soft-fork to complete and will release a new wallet that will allow conversion of all zPIV held in the wallet to PIV. This will mean that all users will be able to fully access their funds immediately once released. This new release will be mandatory, and the zPIV spends will no longer be private in light of this new vulnerability.
Which means that for now, PIVX's privacy has been shut off and zpiv spends are no longer private, putting PIVX at 0 currently.
In Apr 2019 a cryptographic vulnerability was discovered with the ZeroCoin protocol. This was not a coding error but a flaw in the mathematical proof that ZeroCoin's design was based on. This has lead to ZCoin disabling their privacy feature. >We found the root cause of the irregular Zerocoin spends on the 19 April 2019. An emergency update 13.7.9 is now available to disable Zerocoin completely while we move to our Sigma implementation. We are in touch with a number of other Zerocoin projects and are working together to secure it. >We recommend any projects utilizing Zerocoin (regardless of which implementation you are using) to disable Zerocoin on sporks or at a consensus layer. ZCoin has recently on July 23 2019 released their newly updated Sigma privacy protocol which replaces the ZeroCoin protocol. Zerocoin had an issue before that caused them to shut it down, and now they have released the Sigma protocol. It is another encryption based scheme, but this time without the trusted setup and relying on well-known cryptographic primitives, i.e. the algorithms they use to build the encryption are well-known and time-tested. They've been investigated for bugs and are all deployed actively in other systems, thus, a similiar bug becomes less likely. ZeroCoin was groundbreaking, but also very experimental. With this, the Anonymity set size of ZCoin becomes 214 = 16,384. Here is how they describe its functioning:
Sigma is based on the academic paper One-Out-Of-Many-Proofs: Or How to Leak a Secret and Spend a Coin (Jens Groth and Markulf Kohlweiss) which replaces RSA accumulators by utilizing Pedersen commitments and other techniques which cryptographic construction does not require trusted setup. The only system parameters required in the Sigma setup are ECC group specifications and the group generators. This construction was further optimized in the paper Short Accountable Ring Signatures based on DDH (Jonathan Bootle, Andrew Cerulli, Pyrros Chaidos, Essam Ghadafi, Jens Groth and Christophe Petit). Proof sizes are significantly reduced from 25 kB in Zerocoin to 1.5 kB in Sigma which is almost a 17x reduction making it a lot cheaper to store on the blockchain and making it possible to fit much more private send transactions in a block. We also utilize the improved Sigma techniques in the paper Short Accountable Ring Signatures Based on DDH to reduce proof sizes further. This solves one of the biggest problems of Zerocoin without reducing its security. Security via the usage of 256 bit ECC curves in Sigma is improved compared to 2048 bit RSA used in Zerocoin and is estimated to be equivalent to 3072 bit RSA. Our implementation also uses Pippenger and Straus’ multi exponentiation algorithms for further verification efficiency.
There's a lot of tech speak in there. Suffice it to say that Sigma utilizes well-known cryptographic algorithms without a trusted setup to provide a pretty strong privacy offering, with a anonymity set size more than 10,000.
ZCash is an implementation of the ZeroCash protocol which is an improvement on the ZeroCoin protocol. The cool thing about ZCash is that it also hides the amount of the transaction. ZCash's privacy is optional and the blockchain is split between t-addresses and z-addresses. t-addrs are transparent and contain visible balances just like Bitcoin, which ZCash is a software fork of. z-addrs are shielded. ZCash appears to have two kinds of shielded transactions (shielded and fully shielded). I'm not sure of the difference between them, but according to this handy block explorer: https://explorer.zcha.in/statistics/usage, shielded txs are far more prevalent than fully shielded ones. The difference between them may be that fully shielded txs are transactions between two z-addrs while a tx that is 'just shielded' may be one between a z-addr and a t-addr and possibly a t-addr and a z-addr, but again, I'm not sure. The developers claim that the anonymity set is very large in comparison to coins like Dash, and since it is based on the ZeroCash, it is reasonable to assume its anon set is similarly large and based on a proportion of the supply, though where among the three it stands is of course up for debate/verification. However, with Dash's recent protocol update to v0.13, privateSend now has the second largest possible anonymity set among the privacy coins. At 43 million, it is less than ZEC's (4.3 Billion) but greater than ZCoin's (~16,000) and PIVX's (currently 0), Monero's (only 11) and Bitcoin Cash's (5). Zec's anon-set is perhaps as large as the shielded value colume for any time period, also note that is a lower bound, so for the past month: 394989 ZEC would be the total shielded ZEC, so this seems a reasonable lower-bound on the Anon-set. Its hard to Tell between this and PIVX which is larger. According to this page the anonymity set size for ZEC is 232 = 4,294,967,296 granting it the largest anonymity set size in the space, several orders of magnitude larger than runner-up Dash at ~43,000,000 @ 16 rounds of mixing.
In Monero, the anonymity set is the number of mixins used at the time of your transaction. Which is currently 11 with the most recent update to bulletproofs. Monero originally had optional privacy where the min mixin was 0 and those transactions were transparent like btc's. However, having these 0 mixin transactions together with the higher mixin transactions allowed for higher ones to be deanoned, that and 3 forms of timing analysis attacks forced the min mixin to be raised to 3, then 5 then 7 and finally its current static value. With the latest update the ring size, previously a wallet-configurable parameter, is now fixed at 11 for everyone.
With Bitcoin cash adding its CashShuffle protocol, they too join the ranks of the privacy coins. Each mixing is done with 4 other participants giving an anonymity set of 5.
So in short, if you want to rank privacy coins by their anon-set size (which is the only thing that matters) the list is as follows:
1. ZCash 4,294,967,296
2. Dash 43,046,721
3. ZCoin 16,384
4. Monero 11
5. Bitcoin Cash 5
Note: Each tier except the last generally represents a range of at least >1 order of magnitude greater anonymity set. So ZCash is two orders of magnitude greater than Dash, which is 3 orders of magnitude greater than ZCoin which is 3 orders of magnitude greater than Monero which is in the same order of magnitude as BCH. Monero's default min mixin is 7 and the max definable in the gui wallet IIRC is 26 ring size is fixed at 11 for everyone. It is no longer possible to select your own ring size per tx. Due to the optional nature of how many rounds a user can select in Dash (default 4-16), there is a wide range of possible anon set sizes for Dash, most other coins have a predetermined anon set like Monero which is fixed at 11 currently, and Bitcoin Cash which uses a single round of mixing with 5 total participants. But for Dash, which may on occasion cross into fall into the grey zone between numbers 4 and 2 due to uncertainty around the number of wallets participating, and the fact that an attacker will never know how many rounds a tx is going through, as well as the users ability to choose different rounds. The more rounds selected the higher the anonymity set. Also, because Dash doesn't rely on encryption for its privacy, if you don't catch/trace the transaction when its happening, i.e. by buying up 70% or more of the masternodes in order to attempt to link outputs between participants, you can never deanon it. If you use encryption, especially for the entire blockchain, you paint a large target on your blockchain. If your encryption is ever broken, then all past transactions will be deanoned at once, so not good. This is a benefit of steganography over some encryption based privacy schemes. Edit: Don't worry, my comments and posts are always heavily downvoted, that's how you know they're good stuff!
Android This is a mobile fork of my original Krypton system for PCs. This version runs only on user's Android phones with no servers and no other PC nodes in the system. The blockchain has been designed for mobile phones and is able to completely run on Android without the need for any desktop systems or servers at all. I am unaware of any other mobile blockchain systems, so I believe this to be the first. Let's be clear this is not a mobile version of Craigslist, this is a blockchain version of Craigslist. Krypton P2P tokens - a decentralized bulletin board Krypton is a decentralized bulletin board of products or posts. The program, like Bitcoin, runs on each user's mobile phone so there is no central server. The tokens only exist because of the other users on the system. You can view anyone’s tokens but can only edit the ones you own. The system is kind of like Craigslist but built as a blockchain system. There are a total of 25,000 tokens on the system for people to use. That number cannot be changed unless the users of the system choose to update the protocol. Krypton token Features: No selling fees. Users all over the world can access your items for sale. You can update your listings anytime using your private key. Because no site is hosting the listings they cannot be taken down. Tokens are not free so the quality of products should be high. Tokens can be linked into other websites to become ad space. Add search terms to your listings with others to create decentralized stores. Why is this needed? Soon many websites will be forced to comply with government policies like in China and Russia. https://www.npr.org/sections/thetwo-way/2018/03/23/596460672/craigslist-shuts-down-personals-section-after-congress-passes-bill-on-traffickin Program UI: Home Screen On the home screen you can see a display of the most recently updated listings that have a new title. If you go to the search feature at the bottom you can search for a specific item. If you are using a full node this will search your own database. If you are a "Lite Client" it will search the peer you are connected to. If you are not conned to any peers it will say "Tor isn't ready." The QR code on the right is your public key. Tokens is the number of coins you have. Unconfirmed is the number of blocks waiting to be confirmed and (0) is the updates you have made but have not been sent to the network yet. Last Block Time is the time in seconds since the last block. Send Screen: If you click on the SEND (>) button you will see the Send screen. The green number on the top 100100 is the token you are going to transfer to another address. You can enter this manually if you want to transfer a specific ID or you can click GET ID and the program will choose an ID for you that you have. Each token has an ID unlike bitcoin so you have to choose which coin or (Token) you want to send. If you send more then one token the program will go though your list of tokens starting from the lowest number. Get QR code will open the camera so you can scan another user's public key. Listings Screen: If you click on a listing you will see the LISTING Page which looks like the image below. Here you can see the details about the item as well as Contact details at the bottom. Each user will have to come up with the best contact system for them. Using email or some kind of messaging system. Edit Screen: If you click on the EDIT button (Looks like a pencil) from the home screen you will see the image below. Here you can edit any tokens that you have. Adding a picture link from an online image hosting service will allow your listing to have a picture. The Tor system does not have a good URL redirect DNS and so it's good to test your image link first to make sure it will be available for users to see. (Many URLs are not) This service seems to work well: postimg.cc If you want one of those little icons to appear next to your listing on the home screen you can put one of these commands in the "search 1" field of your listing. If you don't it will just display the standard "coins" icon. DISPLAY_BITCOIN DISPLAY_COINS DISPLAY_COMPUTER DISPLAY_CONDO DISPLAY_CONDOM DISPLAY_DOWNLOAD DISPLAY_ELECTRONICS DISPLAY_ENGINE DISPLAY_GAS DISPLAY_GEARS DISPLAY_GIFT DISPLAY_JEWEL DISPLAY_LAW DISPLAY_MAP DISPLAY_MEDAL DISPLAY_OK DISPLAY_PANTS DISPLAY_PAPER DISPLAY_PILL DISPLAY_RING DISPLAY_SCIFI DISPLAY_SUPERMAN DISPLAY_TICKET DISPLAY_XXX Settings: If you go to the SETTINGS (Wrench) button from the home screen you will see the settings screen. (The Play Store version of the app will not have access to these features because of google play polices. But if you need them you can download the full app version from my link at the bottom of this page). Full Node Switch from the beginning this system was built for mobile so for many users who don't want to download the blockchain they can just use the "SPV" version. If Full node is on then your phone will have the whole blockchain if it's off you will only connect to other phones for the info. Mining Switch if you are a Full node and have all the blocks and also have a minimum number of tokens (currently 50) you can be a miner. You will not gain any tokens for mining. It's only to support the system. Google took the app down from the app store because of this feature even though there are no crypto currencies in this app. So the Play Store version doesn't have this button but you can use it on the full version if you download from the link at the bottom of this post. Server Switch if you are a Full Node and want to be a server you can become a Full Node Server which will allow other users to connect to your phone and download blocks from you, as well as view tokens from the blockchain. How does a phone allow for incoming connections? It uses Tor as a Tor hidden service. Use one selected peer this will force the app to connect to only one peer that you choose in the field below. If unchecked then the program will connect to random peers in the database. Peer address this is the address of the peer the program should connect to it should be a .onion address not an IP. It's possible to connect to an IP but this version of the program will not allow you to do so. Insert .onion into the blockchain if you want to be a server then you can add your .onion address into a section of your listing this way other nodes can find you by looking you up in the database not by a separate IP list. This way only people who actually have listings become hosts not just random users. Get new keys if you want to get a new public private account key you can do that here although if you haven't backed up your old key you will lose all your tokens. Copy server address if your server is active you can copy the .onion address of your phone here. Copy public key same as on the home screen this allows you to copy your account public key so others can send you tokens. Get private key this copies your private key to the phone's clipboard so you can back it up in case of loss. Don't give this to anyone or they will steal your tokens. Import private key if you want to import a private key you saved on paper or on another computer you can restore your account here. These are RSA 2048 bit key pairs not Elliptic curve keys like bitcoin. These blockchain tools are mostly for testing and probably will never be needed by users. Reset blockchain this will delete your blockchain history and you will have to re-download it. Delete last block this will delete just the last block from the blockchain in case it has errors or is stale. Delete unconfirmed this will delete the unconfirmed items you have pending to send to the network. This can be used if you made a mistake. Print blocks if you are using an android studio system you can view the block history with a printout here. This will not show visually in the app. Contact details (Public!) these are your contact details that will be inserted into each of your listings as you update them. You can post whatever details are needed for your buyers to contact you but remember they are public and so you should not put anything here that is sensitive. Tor System To run on mobile phones two main changes had to be made to the bitcoin system. One is a different type of blockchain and the other is the use of Tor. Tor is necessary for phones to communicate between each other. Since setting up a server on a phone is pretty much impossible for most users. Using Tor allows for all phones to become clients and servers. In addition to communication, Tor allows for two other main benefits. First, it hides users from some threats and is a good fit for a system like this. But also Tor allows each phone to become a server that can be accessed from regular Tor browsers all over the world. So having the app on your phone is not necessary, just a Tor browser can suffice. However, if you want to update tokens or transfer them you would need the app. The server in this app can distinguish between requests from other nodes and browsers by the header field. If there is no header it's a node, if there is a header it's a browser. If you connect as a node it's JSON if you connect as a browser it's HTML. If users want to connect to the system but they don't have the app they can just connect to the phone by going to the phone's .onion address like this: http://md4kofpseowoo2hp.onion this allows for anyone anywhere in the world to view the status of the system from a regular PC without using the app. This could become much more valuable later on in building decentralized community websites. Blockchain The blockchain has been converted into more of a "worm chain" it moves along though time but it doesn't get any longer. Each block from the back is moved to the front, moving it along kind of like how they used to move heavy blocks ages ago with logs. The block moves along the logs and when it gets to far the log from the back is moved to the front. That's pretty much how this works. The blockchain will complete it's run about every month. At that time if any node hasn't updated they would be left out and they wouldn't be able to verity the blocks on their own any longer. That's why Bitcoin doesn't do this, it needs more security. But in this case the database is just information and thus not as important as monetary transactions. I think this is a worthwhile trade off for the benefits it brings to a system like this. But if in the future storage isn't an issue with phones it would be possible to save all the transactions like Bitcoin and have the same security. By just a few changes to the code. FAQ: Any relation to Craigslist the site?: None. What is the mining algorithm: SHA256 same as Bitcoin. Are there any mining pools: no the mining system is designed to be mined on phones no tokens are given out though mining so there's no need for a pool. Is this going to be on any exchanges: I don't think so it's not a currency and so I don't think anyone would want to trade it as such. If anyone wanted to buy or sell a token they could just use the system itself. Why pay fees? What's the coin limit: 25,000 KRC Why so few coins?: the blockchain system for this grows as the number of tokens goes up so the more tokens there are the bigger the database will be and for a phone it's better to keep it as small as possible. In this system the blockchain should be less then 1GB total forever. Are you asking for money to build this system?: no it's already done. But some large scale testing hasn't been done yet. Are there tokens for sale: yes I'm going to give away the first 1,000 for free and the next 1,000 for $1 and so on. If you want free tokens send me a message. Are there any other ways to get tokens: I will give away free tokens to people who want to be servers and testers. Is this on iphone?: no I don't know anything about iphone programming I'm not sure if the tor libraries are available for iphone but I would guess they are. Does it work on ARC Welder?: no I think because the app needs Linux for Tor it doesn't work.

How to fix crashes and low hash rate on my new scrypt rig?
I need help to get past two major problems in my scrypt mining machine (see my config at bottom).
1 problem is system crashes during mining, even with low hash rate
2 problem is the low hash rates. 280x running at 400 k/hs and R9 290 at 180-400 k/hs
So far I have tried mining on Windows 8.1, Litecoin BAMT Linux and SMOS Linux with much luck. On Windows 8.1 I have gone through tons of AMD Driver versions from 13.1, 13.11 beta v9.4, 14.1 beta, 13-12, and bunch of other versions. Even tried couple of DDU clean ups. I have also tried different iners like cgminer, bfgminer, etc. Note on windows 8.1 I can't see GPU temp either. However, the hangs and low hash rates persist. One of the main issues is I can't get around play around with miner settings due crashes. On linux at least I can see GPU temps. But from my testing the system still hangs when running at 400 k/hs on my two R9 280x or 180 k/hs on R9 290. My setting for above on cgminer was (2x 280x and 1x 290 at the end): cgminer.exe --scrypt -I 12,12,12 -shaders 2048,2048,2560 --auto-fan --target-temp 65 Here is my hardware config: MSI Z77A-GD65 Motherboard(highly recommended on bitcoin.org board) Intel Celeron G1620 Corsair RM 850W G.SKILL 8 GB (4GB x 2) Sapphire Radeon R9 280x MSI Gaming R9 280x XFX R9 290x R9-290A-ENFC Anyone got any suggestions on what to try next? Seems like very hard to mine effectively, for me atleast...
