## Komodod
This software is Komodo client, generally you will use this if you want to mine KMD or setup a full node.
It downloads and stores the entire history of Komodo transactions; depending on the speed of your computer and network connection, the synchronization process could take a day or more once the blockchain has reached a significant size.

## About this Project
Komodo is based on Zcash and has been by our innovative consensus algorithm called dPoW which utilizes Bitcoin's hashrate to store Komodo blockchain information into the Bitcoin blockchain. Other new and native Komodo features are the privacy technology called JUMBLR or our assetchain capabilities (one click plug and play blockchain solutions). More details are available under https://komodoplatform.com/.

## Getting started
Dependencies
------------
### Dependencies
```shell
#The following packages are needed:
sudo apt-get install build-essential pkg-config libc6-dev m4 g++-multilib autoconf libtool ncurses-dev unzip git python python-zmq zlib1g-dev wget libcurl4-openssl-dev bsdmainutils automake curl
```
Komodo
------
We have a release process that goes through several stages before it reaches master. This allows the most conservative users just use the master branch, which is only updated after the other branches have signed off on a release.
### Build Komodo
99% of the activity is in the dev branch, this is where I am testing each change one by one and there are literally thousands of updates. Only use this branch if you really want to be on the bleeding edge. I try to keep things stable, but there are times where necessarily there are bugs in the dev branch, since I am actively developing and debugging here. A good rule is to wait for at least 4 hours from the last update before using the dev branch (unless you know what you are doing)
This software is based on zcash and considered experimental and is continously undergoing heavy development.
After things look good in the dev branch, it is propagated to the beta branch, this is the version the notary nodes use. They are knowledegable command line server guys and so they have a keen eye for anything that wasnt caught during the dev cycle.
After the notary nodes verify things are working and the latest release is deemed stable, it is propagated to the dPoW branch. From here an automated Jenkins process builds it for all OS, and since the notary nodes are all unix, it is possible for some issues to be caught at this stage. The dPoW branch is what goes into the GUI installers.
After the GUI are updated and released and it is verified that no significant support issues were created, the master branch is finally updated.
Master branch: exchanges and users that build from the repo without changing branches
dPoW branch: autobuild into GUI installers, unix, osx, windows
beta branch: notary nodes, command line unix
dev branch: bleeding edge, possibly wont even compile, multiple updates per hour
The dev branch is considered the bleeding edge codebase while the master-branch is considered tested (unit tests, runtime tests, functionality). At no point of time do the Komodo Platform developers take any responsbility for any damage out of the usage of this software.
Komodo builds for all operating systems out of the same codebase. Follow the OS specific instructions from below.
#### Linux
```shell
git clone https://github.com/jl777/komodo
git clone https://github.com/komodoplatform/komodo --branch master --single-branch
cd komodo
#you might want to: git checkout <branch>; git pull
./zcutil/fetch-params.sh
# -j8 uses 8 threads - replace 8 with number of threads you want to use
# -j8 = using 8 threads for the compilation - replace 8 with number of threads you want to use
./zcutil/build.sh -j8
#This can take some time.
```
#### OSX
Ensure you have [brew](https://brew.sh) and the command line tools installed (comes automatically with XCode) and run:
```shell
brew update && brew install gcc@6
git clone https://github.com/komodoplatform/komodo --branch master --single-branch
cd komodo
./zcutil/fetch-params.sh
# -j8 = using 8 threads for the compilation - replace 8 with number of threads you want to use
./zcutil/build-mac.sh -j8
#This can take some time.
```
#### Windows
Use a debian cross-compilation setup with mingw for windows and run:
```shell
git clone https://github.com/komodoplatform/komodo --branch master --single-branch
cd komodo
./zcutil/fetch-params.sh
# -j8 = using 8 threads for the compilation - replace 8 with number of threads you want to use
./zcutil/build-win.sh -j8
#This can take some time.
```
**komodo is experimental and a work-in-progress.** Use at your own risk.
Deprecation Policy
------------------
To reset the Komodo blockchain change into the *~/.komodo* data directory and delete the corresponding files by running `rm -rf blocks chainstate debug.log komodostate db.log`
This release is considered deprecated one year after the release day. There
is an automatic deprecation shutdown feature which will halt the node some
time after this one year period. The automatic feature is based on block
height and can be explicitly disabled.
#### Create komodo.conf
# to update an existing version, `git checkout dPoW` if not on that branch already
```shell
git pull
./zcutil/fetch-params.sh
./zcutil/build.sh -j8
```
To reset the blockchain, from *~/.komodo* `rm -rf blocks chainstate debug.log komodostate db.log`
Create komodo.conf
------------------
Create a komodo.conf file:
```
cd ~
mkdir .komodo
cd .komodo
pico komodo.conf
mkdir ~/.komodo
cd ~/.komodo
touch komodo.conf
#Add the following lines to the komodo.conf file:

### Create your own Blockchain based on Komodo
Start mining
------------
Komodo allows anyone to create a runtime fork which represents an independent Blockchain. Below are the detailed instructions:
Setup two independent servers with at least 1 server having a static IP and build komodod on those servers.
#### On server 1 (with static IP) run:
```shell
#iguana documentation shows how to get the btcpubkey and wifstrs that need to be used
#bitcoin also need to be installed with txindex=1 and with rpc enabled
cd ~
cd komodo
#This will return your pubkey eg. "0259e137e5594cf8287195d13aed816af75bd5c04ae673296b51f66e7e8346e8d8" for your address
./src/komodo-cli validateaddress <yourwalletaddres>
#This will give the privkey of your wallet address
./src/komodo-cli dumpprivkey <yourwalletaddres>
#This will import the privkey to be sure the mined coins are placed into your wallet address
./src/komodo-cli importprivkey <yourwalletprivkey>
#To stop the daemon:
./src/komodo-cli stop
#This starts komodo notary - replace genproclimit with number of threads you want to use and add your pubkey
./src/komodod -gen -genproclimit=2 -notary -pubkey="0259e137e5594cf8287195d13aed816af75bd5c04ae673296b51f66e7e8346e8d8" &
#This will get the stats:
./src/komodo-cli getinfo
#To view the process:
ps -ef | grep komodod
#To stop the daemon:
./src/komodo-cli stop
#To view komodod output:
tail -f ~/.komodo/debug.log
#To view all command
./src/komodo-cli help
ASSETCHAINS: -ac_name=name -ac_supply=nnnnn
Both komodod and komodo-cli recognize -ac_name=option so you can create fork from the commandline
./komodod -ac_name=name_of_your_chain -ac_supply=100000 -bind=ip_of_server_1 &

**Zcash is unfinished and highly experimental.** Use at your own risk.
Where do I begin?
-----------------
We have a guide for joining the main Zcash network:
https://github.com/zcash/zcash/wiki/1.0-User-Guide
#### On server 2 run:
```shell
./komodod -ac_name=name_of_your_chain -ac_supply=100000 -addnode=ip_of_server_1 -gen &

## JUMBLR
komodod now has `jumblr_deposit` and `jumblr_secret` RPC calls.
Jumblr works like described previously where all the nodes with jumblr active synchronize their tx activity during the same block to maximize the mixing effect. However, unlike all other mixers/tumblers, you never give up control of your coins to anybody else. JUMBLR uses a one to many allocation of funds, ie. one deposit address and many secret addresses. You can always run multiple komodod daemons to get multiple active deposit addresses.
JUMBLR implements t -> z, z -> z and z -> t transactions to maximize privacy of the destination t (transparent) address. So while it is transparent, its first activity is funds coming from an untracable z address.
Which of the three stages is done is randomly selected at each turn. Also when there is more than one possible transaction at the selected stage, a random one is selected. This randomization prevents analyzing incoming z ->t transactions by its size to correlate it to the originating address.
`jumblr_deposit <depositaddr>` designates the deposit address as the jumblr deposit address for that session. You can select an address that already has funds in it and it will immediately start jumblr process. If there are no funds, it will wait until you send funds to it.
There are three sizes of a jumblr transaction: 10 KMD, 100 KMD and 1000 KMD. There is also a fixed interval of blocks where all jumblr nodes are active. Currently it is set to be 10, but this is subject to change. Only during every 10*10 blocks are the largest 1000 KMD transactions processed, so this concentrates all the large transactions every N*N blocks.
`jumblr_secret <secretaddress>` notifies JUMBLR where to send the final z -> t transactions. In order to allow larger accounts to obtain privacy, up to 777 secret addresses are supported. Whenever a z -> t stage is activated, a random secret address from the list of the then active secret addresses is selected.
#### Practical Advice:
Obtaining privacy used to be very difficult. JUMBLR makes it as simple as issuing two command line calls. Higher level layers can be added to help manage the addresses, ie. linking them at the passphrase level. Such matters are left to each implementation.
Once obtained, it is very easy to lose all the privacy. With a single errant transaction that combines some previously used address and the secretaddress, well, the secretaddress is no longer so private.
The advice is to setup a totally separate node!
This might seem a bit drastic, but if you want to maintain privacy, it is best to make it look like all the transactions are coming from a different node. The easiest way for most people to do this is to actually have a different node.
It can be a dedicated laptop (recommended) or a VPS (for smaller amounts) with a totally fresh komodod wallet. Generate an address on this wallet and use that as the jumblr_secret address on your main node. As the JUMBLR operates funds will teleport into your secret node's address. If you are careful and never use the same IP address for both your nodes, you will be able to maintain very good privacy.
Of course, don't send emails that link the two accounts together! Dont use secret address funds for home delivery purchases! Etc. There are many ways to lose the privacy, just think about what linkages can be dont at the IP and blockchain level and that should be a useful preparation.
What if you have 100,000 KMD and you dont want others to know you are such a whale?
Instead of generating 1 secret address, generate 100 and make a script file with:
```shell
./komodo-cli jumblr_secret <addr0>
./komodo-cli jumblr_secret <addr1>
...
./komodo-cli jumblr_secret <addr99>
```
And make sure to delete all traces of this when the JUMBLR is finished. You will end up with 100 addresses that have an average of 1000 KMD each. So as long as you are careful and dont do a 10,000 KMD transaction (that will link 10 of your secret addresses together), you can appear as 100 different people each with 1000 KMD.

## Quick Primer on addnode vs connect ##
## Let's say for instance you use addnode=4.2.2.4 ##
## addnode will connect you to and tell you about the ##
## nodes connected to 4.2.2.4. In addition it will tell ##
## the other nodes connected to it that you exist so ##
## they can connect to you. ##
## connect will not do the above when you 'connect' to it. ##
## It will *only* connect you to 4.2.2.4 and no one else.##
## ##
## So if you're behind a firewall, or have other problems ##
## finding nodes, add some using 'addnode'. ##
## ##
## If you want to stay private, use 'connect' to only ##
## connect to "trusted" nodes. ##
## ##
## If you run multiple nodes on a LAN, there's no need for ##
## all of them to open lots of connections. Instead ##
## 'connect' them all to one node that is port forwarded ##
## and has lots of connections. ##
## Thanks goes to [Noodle] on Freenode. ##

The SetAssetFillamounts() and ValidateAssetRemainder() work in tandem to calculate the vouts for a fill and to validate the vouts, respectively.
This pair of functions are critical to make sure the trading is correct and is the trickiest part of the assets contract.
//vin.0: normal input
//vin.1: unspendable.(vout.0 from buyoffer) buyTx.vout[0]
//vin.2+: valid CC output satisfies buyoffer (*tx.vin[2])->nValue
//vout.0: remaining amount of bid to unspendable
//vout.1: vin.1 value to signer of vin.2
//vout.2: vin.2 assetoshis to original pubkey
//vout.3: CC output for assetoshis change (if any)
//vout.4: normal output for change (if any)
//vout.n-1: opreturn [EVAL_ASSETS] ['B'] [assetid] [remaining asset required] [origpubkey]
ValidateAssetRemainder(remaining_price,tx.vout[0].nValue,nValue,tx.vout[1].nValue,tx.vout[2].nValue,totalunits);
Yes, this is quite confusing...
In ValudateAssetRemainder the naming convention is nValue is the coin/asset with the offer on the books and "units" is what it is being paid in. The high level check is to make sure we didnt lose any coins or assets, the harder to validate is the actual price paid as the "orderbook" is in terms of the combined nValue for the combined totalunits.
We assume that the effective unit cost in the orderbook is valid and that that amount was paid and also that any remainder will be close enough in effective unit cost to not matter. At the edge cases, this will probably be not true and maybe some orders wont be practically fillable when reduced to fractional state. However, the original pubkey that created the offer can always reclaim it.

/*
CCcustom has most of the functions that need to be extended to create a new CC contract.
A CC scriptPubKey can only be spent if it is properly signed and validated. By constraining the vins and vouts, it is possible to implement a variety of functionality. CC vouts have an otherwise non-standard form, but it is properly supported by the enhanced bitcoin protocol code as a "cryptoconditions" output and the same pubkey will create a different address.
This allows creation of a special address(es) for each contract type, which has the privkey public. That allows anybody to properly sign and spend it, but with the constraints on what is allowed in the validation code, the contract functionality can be implemented.
what needs to be done to add a new contract:
1. add EVAL_CODE to eval.h
2. initialize the variables in the CCinit function below
3. write a Validate function to reject any unsanctioned usage of vin/vout
4. make helper functions to create rawtx for RPC functions
5. add rpc calls to rpcserver.cpp and rpcserver.h and in one of the rpc.cpp files
6. add the new .cpp files to src/Makefile.am
IMPORTANT: make sure that all CC inputs and CC outputs are properly accounted for and reconcile to the satoshi. The built in utxo management will enforce overall vin/vout constraints but it wont know anything about the CC constraints. That is what your Validate function needs to do.
Generally speaking, there will be normal coins that change into CC outputs, CC outputs that go back to being normal coins, CC outputs that are spent to new CC outputs.
Make sure both the CC coins and normal coins are preserved and follow the rules that make sense. It is a good idea to define specific roles for specific vins and vouts to reduce the complexity of validation.

#include "CCassets.h"
/*
Assets can be created or transferred.
native coins are also locked in the EVAL_ASSETS address, so we need a strict rule on when utxo in the special address are native coins and when they are assets. The specific rule that must not be violated is that vout0 for 'b'/'B' funcid are native coins. All other utxo locked in the special address are assets.
To create an asset use CC EVAL_ASSETS to create a transaction where vout[0] funds the assets. Externally each satoshi can be interpreted to represent 1 asset, or 100 million satoshis for one asset with 8 decimals, and the other decimals in between. The interpretation of the number of decimals is left to the higher level usages.
Once created, the assetid is the txid of the create transaction and using the assetid/0 it can spend the assets to however many outputs it creates. The restriction is that the last output must be an opreturn with the assetid. The sum of all but the first output needs to add up to the total assetoshis input. The first output is ignored and used for change from txfee.
What this means is that vout 0 of the creation txid and vouts 1 ... n-2 for transfer vouts are assetoshi outputs.
There is a special type of transfer to an unspendable address, that locks the asset and creates an offer for all. The details specified in the opreturn. In order to be compatible with the signing restrictions, the "unspendable" address is actually an address whose privkey is known to all. Funds sent to this address can only be spent if the swap parameters are fulfilled, or if the original pubkey cancels the offer by spending it.
Types of transactions:
create name:description -> txid for assetid
transfer <pubkey> <assetid> -> [{address:amount}, ... ] // like withdraw api
selloffer <pubkey> <txid/vout> <amount> -> cancel or fillsell -> mempool txid or rejected, might not confirm
buyoffer <amount> <assetid> <required> -> cancelbuy or fillbuy -> mempool txid or rejected, might not confirm
exchange <pubkey> <txid/vout> <required> <required assetid> -> cancel or fillexchange -> mempool txid or rejected, might not confirm
assetsaddress <pubkey> // all assets end up in a special address for each pubkey
assetbalance <pubkey> <assetid>
assetutxos <pubkey> <assetid>
assetsbalances <pubkey>
asks <assetid>
bids <assetid>
swaps <assetid>

This file implements a simple CC faucet as an example of how to make a new CC contract. It wont have any fancy sybil protection but will serve the purpose of a fully automated faucet.
In order to implement a faucet, we need to have it funded. Once it is funded, anybody should be able to get some reasonable small amount.
This leads to needing to lock the funding in a CC protected output. And to put a spending limit. We can do a per transaction spending limit quite easily with vout constraints. However, that would allow anybody to issue thousands of transactions per block, so we also need to add a rate limiter.
To implement this, we can simply make any faucet vout fund the faucet. Then we can limit the number of confirmed utxo by combining faucet outputs and then only using utxo which are confirmed. This combined with a vout size limit will drastically limit the funds that can be withdrawn from the faucet.

/*
The rewards CC contract is initially for OOT, which needs this functionality. However, many of the attributes can be parameterized to allow different rewards programs to run. Multiple rewards plans could even run on the same blockchain, though the user would need to choose which one to lock funds into.
At the high level, the user would lock funds for some amount of time and at the end of it, would get all the locked funds back with an additional reward. So there needs to be a lock funds and unlock funds ability. Additionally, the rewards need to come from somewhere, so similar to the faucet, there would be a way to fund the reward.
Additional requirements are for the user to be able to lock funds via SPV. This requirement in turns forces the creation of a way for anybody to be able to unlock the funds as that operation requires a native daemon running and cant be done over SPV. The idea is to allow anybody to run a script that would unlock all funds that are matured. As far as the user is concerned, he locks his funds via SPV and after some time it comes back with an extra reward.
In reality, the funds are locked into a CC address that is unspendable, except for some special conditions and it needs to come back to the address that funded the lock. In order to implement this, several things are clear.
1) each locked CC utxo needs to be linked to a specific rewards plan
2) each locked CC utxo needs to know the only address that it can be unlocked into
3) SPV requirement means the lock transaction needs to be able to be created without any CC signing
The opreturn will be used to store the name of the rewards plan and all funding and locked funds with the same plan will use the same pool of rewards. plan names will be limited to 8 chars and encoded into a uint64_t.
The initial funding transaction will have all the parameters for the rewards plan encoded in the vouts. Additional fundings will just increase the available CC utxo for the rewards.
Locks wont have any CC vins, but will send to the RewardsCCaddress, with the plan stringbits in the opreturn. vout1 will have the unlock address and no other destination is valid.
Unlock does a CC spend to the vout1 address
