Gocoin

7 | Gocoin is a full Bitcoin solution written in Go language (golang).
8 |
9 | The software's architecture is focused on maximum security and good performance.
10 |
11 | The client (p2p node) is an application independent from the wallet.
12 |
13 | The wallet is deterministic and password seeded. As long as you remember the password, you do not need any backups of your wallet.
14 |
15 | In addition there is also a set of more and less useful tools. They are all inside the tools/ folder. Each source file in that folder is a separate tool.
16 |
17 | See external links to read some additional info about the project. 18 | 19 | -------------------------------------------------------------------------------- /website/gocoin_manual.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 |

User Manual

Client and wallet

8 | The two basic components of the software are: 9 | 12 | 13 |

Wallet without client

14 | It is also possible to use the wallet without the client. 15 | For such purpose there is a tool called balio.
16 | The tool can download the balance data from popular block explorers and save it on disk in a format recognized by the wallet.
17 | 18 |

User interface

19 | The applications are console only (no GUI window), although the client node has a fairly functional and quite convenient web interface 20 | (to be used with a web browser). 21 | 22 | 23 |

Client node

7 | Run client -h to see all available command line switches. Some example ones are: 8 |
9 |
10 | -t - use Testnet (instead of regular bitcoin network)
11 | -ul=NN - set maximum upload speed to NN kilobytes per second
12 | -dl=NN - set maximum download speed to NN kilobytes per second
13 | 14 |
15 | To run the client on a remote Linux server (via ssh connection), you probably want to get adventage of screen command. 16 |
17 |

TextUI

18 | When the client is already running you have an interactive, text command based interface, on the console.
19 | Type help to see the possible commands. 20 |
21 | 22 |

WebUI

23 | There is also a web interface that you can operate with a web browser.
24 |
25 | 26 | Make sure to have the www/ folder in the location where you execute the client from.
27 | The folder contains files that are an essencial part of the WebUI application.
28 |
29 | WebUI application is tested with Google Chrome, but should be compatible with any modern web browser.
30 |
31 | By default (for security reasons) WebUI is available only from a local host, via http://127.0.0.1:8833/
32 |
33 |

Remote server

34 | In order to use WebUI securely on a remote server, set up ssh tunneling to port 8833.
35 |
36 |

Local network

37 | If you run the node on a local network and want to have access to its WebUI from different computers:
38 | 42 |
43 | Read more about the config file at the config file page. 44 | 45 | -------------------------------------------------------------------------------- /website/gocoin_issues.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 |

Known issues

7 | 8 |

Volatile UTXO database

9 | 10 | When you start client node for the first time, it will go trough the process of downloading entire bitcoin 11 | block chain and building the UTXO database. 12 | To speed up this process the database is not being flushed to disk as the block processing goes on.
13 |
14 | The node only writes it to disk when either all the blocks are downloaded or when the node's shutdown has 15 | been requested from a user interface (e.g. text command 'quit' was given). 16 | If you kill the process or reboot the machine, you will loose all your hard worked UTXO changes! 17 | Therefore, to save the work as the new blocks are being processed, you should once for awhile quit the node and start it again. 18 | This BTW may also have a positive impact on memory consumption, allowing you to set up the node with less RAM (e.g. 13GB).
19 |
20 | When the node is synchronized, it flushes UTXO database to disk once for awhile. 21 | Killing it then won't have such a bad consequences, as it will start with the most recently written version of the database 22 | and only apply the data from the blocks that came later.
23 |
24 |

Coinbase maturity

25 | According to the block chain protocol, generated coins can be spent only after 100 confirmations.
26 | Users should be aware that fetching a wallet's balance from the client returns also immature coinbase transactions.
27 | Because wallet has no way of knowing if a coinbase output is mature enough, it always considers it mature.
28 | But be aware that the network will not accept your signed transaction until all of the mined coins that it is trying to spend 29 | get at least 100 confirmations.
30 |
31 |

Mining API

32 | The mining RPC API is experimental and had been implemented in March 2016 - long before the segwit support was added.
33 | It was tested on Testnet3 and worked well, but only for one mining setup. 34 | It has not been used ever since then and at this moment shall be considered unusable.
35 | If you are interested in using Gocoin node for mining, please contact me, so I can help you with any issues that may need resolving, 36 | before you start throwing any hash power onto it.
37 |
38 |

Litecoin support in wallet

39 | The wallet only supports Litecoin's P2PKH address types (such that start from L...).
40 | No segwit or multisig suport for Litecoin. It might work, but has not been tested.

Tweaks

7 | On this page you can find ways to improve performance or lower resource consumptions of your running node.
8 |

Faster Elliptic Curve verifications

9 | You can use external secp256k1 library (written in C and assembler) 10 | which is up to 4 times faster when it comes to EC_Verify operations.
11 | 12 | In order to use an external library, copy either the file sipadll.go (Windows only) 13 | or sipasec.go (any OS), from the folder gocoin/client/speedups/ to 14 | gocoin/client/
15 | 16 | After copying a speedup file to the client folder, rebuild and restart the client.
17 | 18 |

sipadll.go (Windows only)

19 | To use sipadll.go speedup, you have to place secp256k1.dll 20 | in a folder where Windows looks for executables (e.g. C:\WINDOWS)
21 | 22 | Note: You can find secp256k1.dll in gocoin/tools/sipa_dll/ 23 | or you can download it from sourceforge.net 24 | (it's inside secp256k1.dll-amd64.zip).
25 | 26 |

sipasec.go

27 | In order to use sipasec.go speedup, build and install secp256k1 library in your system.
28 |
29 | On Debian based Linux system, execute the following steps:
30 | 31 |   sudo apt-get install gcc autoconf libtool make
32 |   git clone https://github.com/bitcoin/bitcoin.git
33 |   cd bitcoin/src/secp256k1/
34 |   ./autogen.sh
35 |   ./configure
36 |   make
37 |   sudo make install
38 |
39 | Note: When the library is properly installed, executing go test from 40 | gocoin/lib/others/cgo/sipasec/ says PASS 41 | 42 |
43 |

Disable wallet functionality

44 | 45 | In order to save system memory used by running client and to improve block processing times, you can disable wallet functionality.
46 | In order to do so, use TextUI command wallet off or click the disable wallet button on the bottom of the Wallet page in the WebUI.
47 |
48 | Note that you can switch the wallet functionality back on any time when the node is running.
49 | If you don't want the wallet functionality to automatically enable after the node is started, 50 | set the value of AllBalances.AutoLoad to false in the config file. 51 | 52 | 53 | -------------------------------------------------------------------------------- /.travis.yml: -------------------------------------------------------------------------------- 1 | ## ====================================================================== 2 | 3 | ## cccccccccc pppppppppp 4 | ## cccccccccccccc pppppppppppppp 5 | ## ccccccccccccccc ppppppppppppppppppp 6 | ## cccccc cc ppppppp pppppp 7 | ## cccccc pppppppp pppppp 8 | ## cccccc ccccpppp pppppp 9 | ## cccccccc cccccccc pppp ppppppp 10 | ## ccccccccccccccccc ppppppppppppppp 11 | ## cccccccccccc pppppppppppppp 12 | ## cccccccc pppppppppppp 13 | ## pppppp 14 | ## pppppp 15 | 16 | ## ====================================================================== 17 | ## Copyright © 2018.

Installation

7 |

System requirements

8 | 9 | If you only want to use the wallet with the corresponding balio tool, 10 | you can run it on anything that your go compiler can build for.
11 | For instance, it will work on even the oldest Raspberry Pi model A with 256MB of RAM. 12 |

13 | 14 | However, in order to run the full node (client), you need a 64-bit OS with at least 15 GB of RAM.
15 | You also need a file system that supports large files (bigger than 4GB) and a decent size of a free space on it.
16 |
17 | Note that you can purge blocks from disk, allowing you to run the node with a limited storage (e.g. 20GB).
18 | See config file values: 19 | Memory.MaxDataFileMB and Memory.DataFilesKeep (set this one to non-zero, e.g. 10)
20 |
21 | The node runs very well on Linux based virtual servers, as long as they have enough RAM.
22 | Find below a list of example providers. Most of them you can rent per-hour (estimated monthly cost in brackets).
23 | Waveride (€20) 24 | • 25 | Scaleway (€25) 26 | • 27 | Vultr (€80) 28 | • 29 | DigitalOcean (€80) 30 | • 31 | Amazon AWS ($100) 32 | • 33 | Gogle Cloud ($100) 34 |
35 | 36 |

Build from source

37 | 38 | You will need git and go commands installed in your system and in most cases 39 | (not for Windows) also gcc (e.g. sudo apt-get install gcc)
40 |
41 | Once you are ready with that, simply execute go get github.com/piotrnar/gocoin to download all the sources and dependencies.
42 |  Note: Sources will be placed within your GOPATH folder, in scr/github.com/piotrnar/gocoin.
43 |  Note: Execute go env GOPATH to see where your GOPATH folder is.
44 |
45 | Then go to gocoin/client/ and execute go build there. 46 | Do the same in gocoin/wallet/, to build the wallet.
47 | In order to build balio or some other tool, go to gocoin/tools/ and do go build balio.go
48 |
49 | 50 | The process is also described in the main README.md file of the github repo 51 | piotrnar/gocoin
52 |
53 | 54 |

Setup wallet

7 | Run wallet -h to see all available command line switches. 8 |
9 | 10 |

Setup your seed

11 | Wallet is deterministic and the only thing you need to set it up is the seed password.
12 | As long as you remember the password, you do not need to backup the wallet ever.
13 | You can either enter this password each time when running the wallet, or you can store it in a file called .secret and never be asked to enter it again.
14 |
15 | 16 | You do not need to use a memorable password. Instead you can create a random secret seed, e.g. using a command like this:
17 |     cat /dev/urandom | tr -cd a-zA-Z0-9 | head -c 27 > .secret
18 | Note: using a password that you cannot memorize, make sure to have a backup of your .secret file. 19 |
20 | 21 |

Export public addresses

22 | After you setup your wallet in a secured environment, you should export its public addresses.
23 |
24 | In order to do this, just run wallet -l and your wallet's public addresses will be written to wallet.txt.
25 |
26 | 27 | 28 |

Security precautions

29 | Make sure that the disk with .secret file is encrypted.
30 |
31 | 32 | The seed password is the key to your entire wallet and the function used to calculate it is double SHA256, which is pretty easy to compute.
33 | That is why it is very important for you to make sure that the password you're choosing will be resistant to brute force and dictionary attacks.
34 |
35 | If you choose to use a memorable seed-password (aka brain wallet), 36 | make it at least 20 characters long, preferably more than 30. 37 | Use both cases of letters, digits and sepcial characters. 38 | Try to avoid using words that can be found in a dictionary and never use sentences that can be found in Google.
39 |
40 | If you decide to write down the password, because you are affraid of forgetting it, 41 | try to describe it as a puzzle that ony you can understad. Avoid writing down the password as is.
42 |
43 | 44 | Are brain wallets less secure from those based on a random number generator?
45 | It is debatable.
46 | There are people claiming that brain wallets aren't secure because brains cannot possibly be a good source of entropy.
47 | If you have such a brain, make sure to consider this risk (e.g. use a random generator to create the content of the .secret file).
48 | Otherwise coming out with a memorable though uncrackable seed, gives you a more secure and very convenient solution, 49 | because you get rid of backups that are a week point of the wallet's security and you never have to carry the wallet file with you.
50 |
51 | 52 |

Importing other private keys

53 | You can import keys from your existing bitcoin wallet, as well as keys generated by other tools (all kind of key/address generators).
54 |
55 | 56 | The key that you want to import must be in base58 encoded format, which looks somehow like 5KJvsngHeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS. To export a private key from the official bitcoin wallet use dumprivkey RPC command. To import such a key into your Gocoin wallet, just store the base58 encoded value in a text file named .others (each key must be in a separate line). You can also place a key's label in each line, after a space.
57 |
58 | 59 | The imported keys will extend the key pool of the deterministic ones (that come from your password-seed). After Importing each new key, you should redo wallet -l to get an updated wallet.txt for your client. 60 | 61 |
62 | 63 |
64 | 65 |
66 | 67 |

Optional: setup your node with the wallet file

68 | Having wallet.txt file generated at the wallet machine, use Wallet page of WebUI and store the content of 69 | this file as a wallet in your browser. You can choose any name you want and you can change labels for the addresses. 70 | 71 | -------------------------------------------------------------------------------- /lib/others/sys/hidepass_unix.go: -------------------------------------------------------------------------------- 1 | // ====================================================================== 2 | 3 | // cccccccccc pppppppppp 4 | // cccccccccccccc pppppppppppppp 5 | // ccccccccccccccc ppppppppppppppppppp 6 | // cccccc cc ppppppp pppppp 7 | // cccccc pppppppp pppppp 8 | // cccccc ccccpppp pppppp 9 | // cccccccc cccccccc pppp ppppppp 10 | // ccccccccccccccccc ppppppppppppppp 11 | // cccccccccccc pppppppppppppp 12 | // cccccccc pppppppppppp 13 | // pppppp 14 | // pppppp 15 | 16 | // ====================================================================== 17 | // Copyright © 2018.

It is deterministic and password seeded. 23 | As long as you remember the password, you do not need any backups ever. 24 | 25 | # Requirements 26 | 27 | ## Hardware 28 | 29 | **Client**: 30 | 31 | * 64-bit architecture OS and Go compiler. 32 | * File system supporting files larger than 4GB. 33 | * At least 15GB of system memory (RAM). 34 | 35 | **Wallet**: 36 | 37 | * Any platform that you can make your Go (cross)compiler to build for (Raspberry Pi works). 38 | * For security reasons make sure to use encrypted swap file (if there is a swap file). 39 | * If you decide to store your password in a file, have the disk encrypted (in case it gets stolen). 40 | 41 | ## Operating System 42 | Having hardware requirements met, any target OS supported by your Go compiler will do. 43 | Currently that can be at least one of the following: 44 | 45 | * Windows 46 | * Linux 47 | * OS X 48 | * Free BSD 49 | 50 | ## Build environment 51 | In order to build Gocoin-cash yourself, you will need the following tools installed in your system: 52 | 53 | * **Go** (version 1.8 or higher) - http://golang.org/doc/install 54 | * **Git** - http://git-scm.com/downloads 55 | 56 | If the tools mentioned above are all properly installed, you should be able to execute `go` and `git` 57 | from your OS's command prompt without a need to specify full path to the executables. 58 | 59 | ### Linux 60 | 61 | When building for Linux make sure to have `gcc` installed or delete file `lib/utxo/membind_linux.go` 62 | 63 | # Getting sources 64 | 65 | Use `go get` to fetch and install the source code files. 66 | Note that source files get installed within your GOPATH folder. 67 | 68 | go get github.com/counterpartyxcpc/gocoin-cash 69 | 70 | # Building 71 | 72 | ## Client node 73 | Go to the `cd $GOPATH/src/github.com/counterpartyxcpc/gocoin-cash/client/` folder and execute `go build` there. 74 | 75 | ## Wallet 76 | Go to the `cd $GOPATH/src/github.com/counterpartyxcpc/gocoin-cash/wallet/` folder and execute `go build` there. 77 | 78 | ## Tools 79 | Go to the `tools/` folder and execute: 80 | 81 | go build 82 | example: go build btcversig.go 83 | 84 | Repeat the `go build` for each source file of the tool you want to build. 85 | 86 | # Binaries 87 | 88 | Windows or Linux (amd64) binaries can be downloaded from 89 | 90 | (T.B.A) @todo, No binaries yet released (Oct 3, 2018) 91 | 92 | Please note that the binaries are usually not up to date. 93 | We strongly encourage everyone to build the binaries. 94 | 95 | # Development 96 | 97 | Although it is an open source project, we will accept merge and any pull requests, however we need to 98 | have contributors assign copyright to the CCA so we may continue to operate within the bounds of our 99 | limited software license agreement to the original project.
