multichain's Introduction

MultiChain

MultiChain is an open source platform for private blockchains, which offers a rich set of features including extensive configurability, rapid deployment, permissions management, native assets and data streams. Although it is designed to enable private blockchains, MultiChain provides maximal compatibility with the bitcoin ecosystem, including the peer-to-peer protocol, transaction/block formats and Bitcoin Core APIs/runtime parameters.

System requirements

These compilation instructions have been tested on Ubuntu 16.04 x64 (xenial) and Ubuntu 18.04 x64 (bionic) only.

C++ compilers are memory-hungry, so it is recommended to have at least 1 GB of memory available when compiling MultiChain. With less memory, compilation may take much longer due to swapfile thrashing.

Linux Build Notes (on Ubuntu 16.04 x64 or later)

Install dependencies

sudo apt-get update
sudo apt-get install -y software-properties-common
sudo apt-get install -y build-essential libtool autotools-dev automake pkg-config git
sudo apt-get install libboost-all-dev
sudo apt-get install libevent-dev

Clone MultiChain

git clone https://github.com/MultiChain/multichain.git

Prepare to download or build V8

cd multichain
MULTICHAIN_HOME=$(pwd)
mkdir v8build
cd v8build

You can use pre-built headers and binaries of Google's V8 JavaScript engine by downloading and expanding linux-v8.tar.gz in the current directory. If, on the other hand, you prefer to build the V8 component yourself, please follow the instructions in V8.md.

Compile MultiChain for Ubuntu (64-bit)

cd $MULTICHAIN_HOME
./autogen.sh
./configure
make

Notes

This will build multichaind, multichain-cli and multichain-util in the src directory.
The release is built with GCC after which strip multichaind strings the debug symbols, which reduces the executable size by about 90%.

Windows Build Notes

Please see the instructions in win.md to build MultiChain for use with Windows.

Mac Build Notes (on MacOS Sierra)

Please see the instructions in mac.md to build MultiChain for use with MacOS.

multichain's Issues

getnewadress or keypollrefill - return error in cold wallet

Hi,

I just can't generate a new address in cold wallet.

Using the cold wallet client, if I enter getnewadress, I get this error:
$ Keypool ran out, please call keypoolrefill first .

Then, trying to run keypoolrefill, or keypoolrefill=1000 or keypool=100, I get this error:
$ Method not available in cold version of MultiChain.

On a fun fact, the keypool= option is available in the cold wallet help menu.

I tried run the keypool command on a unlock cold wallet with walletpassphrase abcxyz, but same result, as trying to run command on hot wallet, where the command seems to work without any flaw but dosen't help on the cold wallet getnewaddress issue.

Anyone know ho to get new address in a cold wallet?

Regards,

Inz

Mac OS Binary

Please provide the userbase a macos binary.
I already create one:
https://github.com/bioharz/multichain/releases/tag/1.0.6
But please compile your own version and create a release.
Thank you!

Compiling MultiChain on Mac OS X Mojave

Greetings,

I'm trying to compile Multichain on Mac OSX Mojave - Xcode 11
I've followed the readme instruction which states to use boost @1.57
Compilation throws the following errors.

Would you please help solve the issue ?

Thank you

Sincerely

Processes are killed with segfault on high load

When a lot of requests are made against the RPC API, multichain processes regularily fail with segfault.

Here is what I see in the systemd journal:

Jan 06 00:06:15  systemd[1]: [email protected]: Main process exited, code=killed, status=11/SEGV
Jan 06 00:06:15  systemd[1]: [email protected]: Unit entered failed state.
Jan 06 00:06:15  systemd[1]: [email protected]: Failed with result 'signal'.

I am seeing this error regularily coming up in times where a lot of requests are made against the RPC API, when the amount of requests was low it did not happen before.

Multichain Version: 1.0.2, I am using the binaries from the website.

To provide more information about the problem I'd compile multichain myself and run it with gdb, I wonder however, which branch I should use, as this repo does not seem to have any tags?

Missing error message details on non-mandatory-script-verify-flag

When sendrawtransaction is used with a transaction signature not in canonical form, the following error is returned:

16: ConnectInputs failed: non-mandatory-script-verify-flag (No error)

(No error) should be the actual error message, but it looks like error message is being taken from the wrong CScriptCheck instance:

multichain/src/core/main.cpp

Lines 2147 to 2150 in 4ddb443

    
           CScriptCheck check(*coins, tx, i, 
        
                   flags & ~STANDARD_NOT_MANDATORY_VERIFY_FLAGS, cacheStore); 
        
           if (check()) 
        
               return state.Invalid(false, REJECT_NONSTANDARD, strprintf("non-mandatory-script-verify-flag (%s)", ScriptErrorString(check.GetScriptError())));

check is the instance that succeeded, so it is always "No error". The error message from the check that failed should be used instead.

Does not build on Debian Stretch (libboost 1.62)

Getting a lot of errors similar to this:

chainparams/chainparams.cpp:177:51: error: ambiguous overload for ‘operator=’ (operand types are ‘std::vector’ and ‘boost::assign_detail::generic_list’)

nValue of CTxOut only holding 0 when at CreateNewBlock

Poking around with the debugger at CreateNewBlock. It seems that the nValue of all the CTxOuts taken from tx.vin and tx.vout are set to 0. For a quick check you can run the current tx's GetValueOut and it will report 0. I had to recompile with O0 in order to verify this. I recommend taking a look, as this would lead to a lot of weird behavior, like the transaction fee not being set properly. CCoinsViewCache is relaying that the txin does have coins, so I suspect the issue isn't far away. Although when accessing a given txin's previous output's vout, the nValue is also empty (src/miner/miner.cpp L418-L422)

I couldn't get my SmartFilter working until I removed all of my skipped single quotes from my strings.

Processes are killed with SIGABRT on high load

As it is unrelated to #38, I am making a new issue here.

The following error happens occasionally on different nodes in the blockchain (systemd journal):

I got the same error with the same stack trace multiple times on different nodes in the blockchain.
This one is using the 1.0.2.1-wdebug build, but I have also seen it with 1.0.2.1 without debug symbols so I think it is unrelated to the build type.

I have sent you an email with the blockchain directory of one affected node.

Poor native blockchain currency settings means no one can submit transactions

Took me an hour to get to the bottom of this one:

With the following in your params.dat:

# Native blockchain currency (likely not required)

initial-block-reward = 64               # Initial block mining reward in raw native currency units. (0 - 1000000000000000000)
first-block-reward = 5000000            # Different mining reward for first block only, ignored if negative. (-1 - 1000000000000000000)
reward-halving-interval = 1051200       # Interval for halving of mining rewards, in blocks. (60 - 1000000000)
reward-spendable-delay = 6              # Delay before mining reward can be spent, in blocks. (1 - 100000)
minimum-per-output = 0                  # Minimum native currency per output (anti-dust), in raw units.
                                        # If set to -1, this is calculated from minimum-relay-fee. (-1 - 1000000000)
maximum-per-output = 100000000000000    # Maximum native currency per output, in raw units. (0 - 1000000000000000000)
minimum-offchain-fee = 0                # Minimum fee for publishing off-chain data items, per 1000 bytes, in raw units of native currency. (0 - 1000000000)
minimum-relay-fee = 0                   # Minimum transaction fee, per 1000 bytes, in raw units of native currency. (0 - 1000000000)
native-currency-multiple = 1000000      # Number of raw units of native currency per display unit. (0 - 1000000000)

you get the following error, even as admin, when trying to submit any transaction (I used an issue <1...> votes 1000 1 command during testing, but found the problem when trying to grant admin rights to a second address):

error code: -704
error message:
No unspent output with issue permission

Once the number of blocks exceeds the reward-spendable-delay (in this case 6), then commands start working.

But if you set reward-spendable-delay higher than the total number of blocks made in initial setup, you end up with a useless blockchain where no address has unspent UTXO and hence nothing can be done on the chain. As there are no transactions, block generation halts before the reward-spendable-delay is reached.

Might be worth checking for when setting up a MultiChain for the first time, and rejecting with a suitable message explaining why the params are no good.

multichain-cli can't connect to the remote node

I'm using Chainstack for network and node deployment.

I can interact with RPC via multiple methods described here (curl) and here (JavaScript and Python libraries) but not with multichain-cli.

BerkeleyDB 4.x?

Hi,

I'm trying to get multichain running on an alpine docker container (which implies lots of tinkering and I'm also trying compiling). I wanted to ask why is the BerkeleyDB version forced to 4.X when the latest is 5.3?

Is there a hard reason for this? Can we be a bit more flexible with the version at compile time?

ZeroMQ support?

It seems that multichain does not have ZeroMQ support yet. Some tools in Bitcoin ecosystem rely on ZeroMQ to get new transaction/ block notification. Do you have plan to add it?

SmartFilter: JS-Code size limit?

Hello,

I seem to have hit the maximum size limit that a Smart Filter can have? Inside my code I'm loading an object with ~250k lines of information that I use to verify a few things about the transaction.

When I try to send the filter through Savior I get:

Json: {'result': None, 'error': {'code': -8, 'message': 'Invalid custom fields or filter name, too long'}, 'id': 1}
{'result': None, 'error': {'code': -8, 'message': 'Invalid custom fields or filter name, too long'}, 'id': 1}

However, if I empty my object the filter goes through:

> tloriato$ python3 filterwithObject.py 
Error! Status code: 500
Text: {"result":null,"error":{"code":-8,"message":"Invalid custom fields or filter name, too long"},"id":1}

The saddest part is that I wanted to load other object after this one with 2mi lines 😢

Asset name restriction error with createrawsendfrom

Apparently we can create assets with names which do not respect the 32 characters limitations. Those assets become unusable with their names. We are currently in production with multichain 1.0.2.

How do you think you will correct this issue ?

Here is the scenario to reproduce bug:

createrawsendfrom "<my-address>" '{"<my-address>": {"issue": {"raw": 3}}}' '[{"name": "1234567890123456789012345678901234567890"}]'

Argument list too long

Hello,
I've created a new local environment with a stream in order to publish some documents, not so large (200K). The steps are:

xxd -p pre.pdf | tr -d '\n' > pre.hex
var=$(cat pre.hex)
multichain-cli testenv publish documents pdf $var

And i'm getting the following error:

/usr/local/bin/multichain-cli: The argument list is too long

There's any way to avoid that error ?

ps: It works fine for the first 2184 lines of the xxd output.

Issue transactions are not (or slowly) accepted in the blockchain

I am generating a lot of issue transactions using issuemorefrom API call.

This was working okay when the chain was small, but now I see that nearly all of them are getting rejected with debug.log showing:

2018-02-06 12:30:19 ERROR: AcceptToMemoryPool : inputs already spent
2018-02-06 12:30:19 Tx e8bfb5b419be6a318e3ffd87e6ba3882cc1176e3726d165bfb786eadb07745a1 was not accepted to mempool, setting INVALID flag

An example API call:

{
    "id":"bo5a79a12363437",
    "method":"issuemorefrom",
    "params": [
        "1EaV1JMtbW1AwtcPE8cqGHgiPx1nUiHctU4wVe",
        "1P1jZrdugtWdqwHHCKyZ6ACgeCrSBArDSEhkve",
        "alpcoin",

        0,
        {"description":"exchange from Alpcoin Classic","exchange_rate":"5"}
    ]
}

As far as I understand a coin issue has no inputs to spend so it should not fail. I would consider this a bug in the implementation, or is there something I do not understand correctly?

Item data should be hexadecimal string

What is the correct format for text data streams
I wrote it according to the official API
chain1: publish stream1 key1 '{"text":"hello world"}'
But it always displays the following error

{"method":"publish","params":["stream1","key1","{'text':'hello'}"],"id":1,"chain_name":"chain1"}

error code: -8
error message:
Item data should be hexadecimal string
chain1: publish stream1 key1 '{"text":"hello world"}'

error code: -8
error message:

Arguments:
1. "stream-identifier"              (string, required) Stream identifier - one of the following: stream txid, stream reference, stream name.
2. "key"                            (string, required) Item key
3. "data-hex"                       (string, required) Item data hex string

Result:
"transactionid"                     (string) The transaction id.

Examples:

Is there anything else that needs to be configured?

Simplify Running Two Nodes on One Machine

Right within the Getting Started (https://www.multichain.com/getting-started/) I hit on a problem.

After looking up for a solution, I found this here:

https://www.multichain.com/qa/2817/how-to-run-datadir-in-multichain

This is far too complicated (for a getting-started) and should be drastically simplified. The first contact with MultiChain should be smooth and barrier-free.

Is there any way (without code-level changes) to replace the need of the many cmd-line parameters (`-datadir=.multichain-other -port=10255 -rpcport=10254), e.g. running the tools from within different installation-dirs or similar?

Build fails on OS X Sierra (1.0.2 & 2.0 alpha 1)

Both 1.0.2 (44bdabe) and 2.0 alpha 1 (0a428c7) fail to build on Mac OS X Sierra (w/ LLVM 9.0.0; boost 1.65.1 and boost 1.59) while 1.0.1 (1de5d44) builds just fine.

It seems like the problem has been introduced in ef18500 as the previous commit seems to build correctly.

address not exist in the sample_wallet

Hello,
I can not get the sample wallet to work,
I have created the java and saved it in ~ / BitcoinWallet / BitcoinWallet.conf configuration. But it does not work, if I try to send money to some address of the wallet from multichain, but the console tells me that the address does not exist.
Please help, I do not understand what I should do.
Is the application unfinished?

Blockchain parameter `minimum-per-output` is ignored

On a test chain based on the latest release version (1.0.1) of multichain I was able to create and confirm a 1 raw unit native currency transaction without transaction fee while the blockchain parameters are set to:
minimum-per-output = 10000
minimum-relay-fee = 10000

Maybe I am doing something wrong but it seems to be a bug.

Q: Supported algo/coins?

I would like to know which algo/coins are currently supported? Are there any example configs for existing currencies already supported out of the box using the specific blockchain-params to host nodes for multiple coins out of one daemon and separate configs/processes managing each of them?

Named semaphore generation on Mac OS X

The generation of semaphore names for OS X is making use of rand() without seeding it, which ultimately leads to multichain always trying to use the same semaphore name on each invocation until the machine is rebooted.

                   name[i] = alphanum[rand() % (sizeof(alphanum) - 1)]; 
        
               }

               } 
        
           #else

This becomes a problem when the semaphore isn't cleaned up properly (e.g. after a SIGKILL or even when stopping a running sync with SIGINT, deleting the datadir and trying to sync again, which can get pretty annoying when testing stuff) as multichaind will refuse to start until the machine is rebooted or the semaphore is removed manually

I guess it would be a good idea to add mc_RandomSeed(mc_TimeNowAsUInt()) in init (or before trying to create the semaphore in https://github.com/MultiChain/multichain/blob/master/src/permissions/permission.cpp#L528) to make sure a random semaphore name is used

wallet storage directory inefficient with large number of addresses

I am running a multichaind network where each node manages a lot of addresses.
One node for examples currently has 31039 addresses. The wallet.dat file is 7.4MB, which sounds quite okay, but the wallet directory contains 620388 files and according to du takes about 52G disk space. Accessing the multichain API for information and creating new transactions takes a lot of time.

Are there any plans on improving this? Or is there anything I can configure to make it more efficient?

liststreamitems doesn't work on windows 10?

I receive only an empty array when calling 'multichain-cli.exe testchain liststreamitems "test-stream" false'. liststreamitems on my linux machine works without problems. Is this a general problem on windows?

Just a small note. I had to chmod +x build_detect_platform in src/leveldb to compile.

Backup and Dump Wallet API

if the folder does not exist, the errors returned are.

BackupWallet
{"result":null,"error":{"code":-4,"message":"Error: Wallet backup failed!"},"id":null}
I genuinely had a lot of time waste due to the fact that a file had the same name as an expected folder.. This error was very crude.

DumpWallet
{"result":null,"error":{"code":-717,"message":"Cannot open wallet dump file"},"id":null}
This error is misleading as it suggests that a file be opened - but its the stream that you need to create that cannot be created, due to path not found

Linux 18 Build fail - /v8/v8engine.h:10:10: fatal error: v8.h: No such file or directory #include <v8.h>

Hi,

I'm trying to build the multichain source code but get this error.

"/v8/v8engine.h:10:10: fatal error: v8.h: No such file or directory
#include <v8.h>".

All files are in place. I can see the V8.h file in the folder as referenced in V8engine.h.
Please confirm where the V8 build should go since the "extract in current folder" in instructions is not clear.

Any advice ?

Thanks in advance.

In monitoring system it looks like there's something wrong with the API which is not the case. Any reason to return 500 and not 200?

Travis CI integration for macOS binaries

Hi everyone,

this is not an issue as such, but since I haven't found a mailing list, here it goes. I have forked MultiChain and added Travis CI scripts for the master, 1.0.x-dev, 1.0.x-release, 2.0-dev and 2.0-release branches that build macOS High Sierra binaries (macOS 10.13.6 as of today) and release them to GitHub, whenever I merge your upstream changes and push them. The builds are "versioned" with the latest upstream branch merge commit date (UTC). They do not include a proper README.txt, which you distribute with your pre-compiled packages, as I could not find them in your repository (I only include a README with a reference to the proper upstream tree). However they do contain the multichain-cli, multichain-util, multichaind and multichaind-cold binaries.

If you find this useful, I can open a PR, otherwise I just wanted to put it out here, in case someone does not want to go through the trouble of compiling. I have too many different versions of boost and openssl installed (via brew, self-built or provided binaries) on my machine to compile the thing properly (i.e. weird pointer corruption errors due to linking of different versions, failed assertions and whatnot). The binaries mentioned above run fine on my macOS Mojave 10.14.3 as well, and the very simple test case included in the .travis.yml scripts succeeds on High Sierra 10.13.6 on Travis.

As a disclaimer I'll have to say that I need MultiChain as part of a project we are working on, and as such I cannot say I'll be able to maintain this fork, at least on a regular basis (or at all).

Cheers and keep up the great work!

Issuemorefrom spends wrong UTXO

Background

I am trying to create raw transactions with issuemorefrom. I am not using the issuemorefrom api call because I want to store some information in the application that creates the transation before sending it.

The problem

my own issuemorefrom transactions do not have an output that could be spent on new asset issues as it is the case with the transactions generated by issuemorefrom api call. I have not figured out what is the problem here, but that could be my own fault.
when I run issuemorefrom api call after my incorrect transaction is in the network it will spend asset outputs for generating new transactions, making these assets unusable.

How to reproduce

create a new blockchain with permissions, everyone can connect, send, receive.
api call listaddresses -> my admin address is 1RuottrEKTyLbi9EARtppJEwXLwUzPz48eB5s8
api call issue 1RuottrEKTyLbi9EARtppJEwXLwUzPz48eB5s8 '{"name":"cointest","open":true}' 1 0.00000001
api call issuemorefrom 1RuottrEKTyLbi9EARtppJEwXLwUzPz48eB5s8 1RuottrEKTyLbi9EARtppJEwXLwUzPz48eB5s8 cointest 5

The relevant transactions in the network are now:

the original issue TX (A):
- outputs:
  - 0 - the issued assets
  - 1 - the issue metadata
  - 2 - output to be used for further asset issues
the issuemore TX (B):
- inputs:
  - A 2
- outputs:
  - 0 - the issued assets
  - 1 - output to be used for further asset issues

now I create my transaction:

`createrawtransaction '[{"txid":"B","vout":1}]' '{"someaddress":{"issuemore":{"asset":"cointest","raw":500}}}'
appendrawdata hex-from-above '{"details":{"origin":"us","stage":"two"}}'
signrawtransaction hex-from-above [] ['pk of 1RuottrEKTyLbi9EARtppJEwXLwUzPz48eB5s8 obtained via dumpprivkey']
sendrawtransaction hex-from-above

This transaction has only the output of the asset issue and the meta data.

now make api call issuemorefrom 1RuottrEKTyLbi9EARtppJEwXLwUzPz48eB5s8 1RuottrEKTyLbi9EARtppJEwXLwUzPz48eB5s8 cointest 5

This transactions spends the asset issued in step 4! As far as I see this is a major issue and such a transaction should never be accepted on the network.

Issues with floating point precision

When sending high amounts of assets, multichain may reject transactions due to rounding errors in floating point calculation. I was trying to work around this by adding additional outputs that would correct the error, but internal calculations seem to add additional errors.

Steps to reproduce:

create a blockchain alpcointest with asset alpcointest
(issue <adminaddress> '{"name":"alpcointest","open":true}' 1 0.00000001)
Issue 132463363.16643485 coins to an address
Try to send 30000000 to another address using the above amount as input (I am using raw transactions)

sendrawtransaction fails with

error 500 Internal Server Error: {"result":null,"error":{"code":-26,"message":"64: Asset transfer script rejected - mismatch in input/output quantities"},"id":"bo5b79fd2b28f59"}

The raw transaction is:

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

The problem seems to be related to the conversion from raw and qty here:

                    "raw" : 10782874505105000,

reserved identifier violation

I would like to point out that identifiers like “_SECP256K1_UTIL_H_” and “__US_Fork” do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?

3rd party app data

Is it possible to allow a 3rd party app to publish some piece of simple data on my block chain? If yes, how?

Remove unnecessary null pointer checks

An extra null pointer check is not needed in functions like the following.

Unable to create and sign 3-to-4 multisig.

Notes:
Chain contains a native currency, and has anyone-can-connect/send/receive set to true.

multichain-cli frogchain getinfo returns: error: couldn't connect to server

Node was started with multichaind frogchain i.e. not as a daemon.

Running the command again didn't give a segmentation fault.

How to use preparelockunspentfrom with external keys

Hi Guys, i needed use preparelockunspentfrom with the external private key, it's possible?

Contribution Guide

I saw in an earlier issue that you guys were working on this but I wanted to check in on progress.

A couple of things that might be helpful would include:

What operating system / version are you developing on?
Using any IDE's and / or tools that are easy to set up with this project?

	CScriptCheck check(*coins, tx, i,
	flags & ~STANDARD_NOT_MANDATORY_VERIFY_FLAGS, cacheStore);
	if (check())
	return state.Invalid(false, REJECT_NONSTANDARD, strprintf("non-mandatory-script-verify-flag (%s)", ScriptErrorString(check.GetScriptError())));

	void* __US_SemCreate()
	{
	sem_t *lpsem;

	lpsem=NULL;

	#ifdef MAC_OSX
	// Create a unique name for the named semaphore
	static const char alphanum[] =
	"0123456789"
	"ABCDEFGHIJKLMNOPQRSTUVWXYZ"
	"abcdefghijklmnopqrstuvwxyz";
	int namelen = 20;
	char name[namelen + 1];
	for (int i = 0; i < namelen; ++i) {
	name[i] = alphanum[rand() % (sizeof(alphanum) - 1)];
	}
	name[namelen] = 0;

	// Create named semaphore as unnamed semaphores are deprecated on OS X.
	lpsem = sem_open(name, O_CREAT \| O_EXCL, 0666, 1);
	if (lpsem == SEM_FAILED) {
	return NULL;
	}
