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 has being evolved from Zcash project, where we used some of their codebase and extended it with new technologies. Same Zcash is based on Bitcoin's code, with differnece Zcash intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Technical details are available in our Protocol Specification.

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.

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)

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

git clone https://github.com/jl777/komodo
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
./zcutil/build.sh -j8
#This can take some time.

to update an existing version, git checkout dPoW if not on that branch already

#bitcoin also need to be installed with txindex=1 and with rpc enabled
cd ~

#This will return your pubkey eg. "0259e137e5594cf8287195d13aed816af75bd5c04ae673296b51f66e7e8346e8d8" for your address

Both komodod and komodo-cli recognize -ac_name=option so you can create fork from the commandline

For license information see the file COPYING. NOTE TO EXCHANGES: https://bitcointalk.org/index.php?topic=1605144.msg17732151#msg17732151 There is a small chance that an outbound transaction will give an error due to mismatched values in wallet calculations. There is a -exchange option that you can run komodod with, but make sure to have the entire transaction history under the same -exchange mode. Otherwise you will get wallet conflicts. To change modes: a) backup all privkeys (launch komodod with -exportdir= and dumpwallet) b) start a totally new sync including wallet.dat, launch with same exportdir c) stop it before it gets too far and import all the privkeys from a) using komodo-cli importwallet filename d) resume sync till it gets to chaintip For example: ./komodod -exportdir=/tmp & ./komodo-cli dumpwallet example ./komodo-cli stop mv ~/.komodo ~/.komodo.old && mkdir ~/.komodo && cp ~/.komodo.old/komodo.conf ~/.komodo.old/peers.dat ~/.komodo ./komodod -exchange -exportdir=/tmp & ./komodo-cli importwallet /tmp/example ############## 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 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 1010 blocks are the largest 1000 KMD transactions processed, so this concentrates all the large transactions every NN blocks. jumblr_secret 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: ./komodo-cli jumblr_secret ./komodo-cli jumblr_secret ... ./komodo-cli jumblr_secret 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.
