About

It is with great excitement that the Matrix AI Network team releases the first major update to the Matrix AI Network! The primary goal of this update is to increase the stability of the network. This update includes tweaks to several attributes including:

Verification Masternode Selection

Any Verification Masternode with a stake exceeding 1/19th of the total MAN tokens staked by all Verification Masternodes is guaranteed selection. All other Verification Masternodes are selected according to their stake. The probability of selection can be estimated using a simple formula:

〖Individual Stake〗^1.45/〖Total Verification Masternodes Stake〗^1.45

The real formula is considerably more complex but yields similar results. The reason we use a more complex algorithm to manage selection is to reduce selection variability in small time periods.

As before, once selected, all Verification Masternodes in a given cycle (300 blocks) serve as the Block Leader, in turn, regardless of stake. The probability of everyone’s starting positions can also be estimated using a simple formula:

〖Individual Stake〗^1.45/〖Total Stake of Selected Verification Masternodes〗^1.45

VIP System

The previous VIP system is completely eliminated and does not impact the selection of Masternodes in any way

Voting Timeout

As before, in order to verify and package transactions in a block, at least 13 of the selected Verification Masternodes must agree via a voting mechanism. If a Verification Masternode fails to vote, they timeout and are replaced. The time to timeout is changed from 20 seconds to 40 seconds

Block Timeout

If a block leader fails to perform their duties, they will timeout and be replaced. The time to timeout is changed from 40 seconds to 60 seconds.

Penalties

Penalties assigned to malicious, mis-deployed and offline Verification Masternodes are increased. Any Verification Masternode that fails to perform its duties for the entirety of a selection cycle will forfeit its next 10 selections.

Target Block Time

The target block time is increased from 6 seconds to 9 seconds.

Block Rewards

Block rewards are increased from 10 MAN tokens to 16 MAN tokens.

Getting Started

Welcome! This guide is intended to get you running on the MATRIX network. To ensure your client behaves gracefully throughout the setup process, please check your system meets the following requirements:

OS Windows, Linux
CPU 8 Core (Intel(R) Xeon(R) CPU X5670 @2.93GHz)
RAM 16G
Free HD 300G
Bandwidth 20M
Build from Source

First of all, you need to clone the source code from MATRIX repository:

Git clone https://github.com/MatrixAINetwork/go-matrix.git, or

wget https://github.com/MatrixAINetwork/go-matrix/archive/master.zip

  • Branch: Master

  • Tag: v1.1.4

Building gman requires both a Go (version 1.7 or later) and a C compiler. You can install them using your favourite package manager. Once the dependencies are installed, run your 'make gman' command

You can also obtain our compiled gman from github https://github.com/MatrixAINetwork/GMAN_CLIENT/tree/master/MAINNET/5.17

Starting up your member nodes (Linux & Mac) - for deposited users

Step 1: Check out what you need to prepare (most of them can be obtaind from go-matrix repository)

/gman: exe file

/MANGenesis.json: genesis file

/chaindata: a folder which you should create

man.json: common profile which shall be put under /chaindata

Step 2: Run Initiate command

./gman  --datadir  ./chaindata/   init    ./MANGenesis.json

Step 3: Visit our web wallet to create a new wallet address, and save your keystore file as well as password.

Please refer to ['Guide to Web Wallet']

Carry out your deposit actions if you want to run for a miner or validator node (you can find steps on the above guide)

Step 4: Copy your keystore file to folder keystore which is generated at Step 2 (/chaindata/keystore)

Step 5: Create a file named signAccount.json under root, and its content is like:

[
  {
    "Address":" MAN.gQAAHUeTBxvgbzf8tFgUtavDceJP ",
    "Password":" pass123456"
  }

]

Then, run:

./gman --datadir ./chaindata aes --aesin ./signAccount.json --aesout entrust.json

Upon the window prompt, you will be asked to set a password (which should contain upper-case letter[s], lower-case letter[s], number[s] and special character[s])

Step 6: Copy the generated entrust.json to root

Step 7: Start gman

./gman --datadir ./chaindata --networkid 1 --debug --verbosity 5  --manAddress [your man.address here] --entrust ./entrust.json --gcmode archive --outputinfo 1 --syncmode full 

for example, 

./gman --datadir ./chaindata --networkid 1 --debug --verbosity 5 --manAddress MAN.gQAAHUeTBxvgbzf8tFgUtavDceJP --entrust ./entrust.json --gcmode archive --outputinfo 1 --syncmode full

In this step, you will need to input the password set in step 5.

Step 8: Run 'Attach': ./gman attach /chaindata/gman.ipc (gman.ipc is generated under /chaindata when starting gman)

Starting up your member nodes (Linux & Mac) - for non-deposited users

Step 1: Check out what you need to prepare (most of them can be obtaind from go-matrix repository)

/gman: exe file

/MANGenesis.json: genesis file

/chaindata: a folder which you should create

man.json: common profile which shall be put under /chaindata

Step 2: Run Initiate command

./gman  --datadir  ./chaindata/   init    ./MANGenesis.json

Step 3: Start ./gman --datadir ./chaindata --networkid 1 --outputinfo 1 --syncmode 'full'

Starting up your member nodes (Windows) - for deposited users

Step 1: Check out what you need to prepare (most of them can be obtaind from go-matrix repository)

/gman: exe file

/MANGenesis.json: genesis file

/chaindata: a folder which you should create

man.json: common profile which shall be put under /chaindata

Step 2: Run Initiate command

gman.exe --datadir chaindata\ init MANGenesis.json

Step 3: Create a file named signAccount.json, whose contents are:

[
  {
    "Address":"MAN.2skMrkoEkecKjJLPz6qTdi8B3NgjU ",
    "Password":"haolin0123"
  }

]

Step 4: Run:

gman.exe --datadir chaindata aes --aesin signAccount.json --aesout entrust.json

Upon the window prompt, you will be asked to set a password (which should contain upper-case letter[s], lower-case letter[s], number[s] and special character[s])

Step 5: Start gman

gman --datadir chaindata  --networkid 1 --debug --verbosity 5  --manAddress  MAN.2skMrkoEkecKjJLPz6qTdi8B3NgjU --entrust entrust.json --gcmode archive --outputinfo 1 --syncmode full

In this step, you will need to input the password set in step 5.

Step 8: Open another window

gman attach ipc:\\.\pipe\gman.ipc 

gman.ipc is generated under /chaindata when starting gman)

Starting up your member nodes (Windows) - for non-deposited users

Step 1: Check out what you need to prepare (most of them can be obtaind from go-matrix repository)

/gman: exe file

/MANGenesis.json: genesis file

/chaindata: a folder which you should create

man.json: common profile which shall be put under /chaindata

Step 2: Run Initiate command

gman.exe --datadir chaindata\ init MANGenesis.json

Step 3: Start gman

gman --datadir chaindata  --networkid 1 --outputinfo 1 -- syncmode full

var NotFound = errors.New("not found")

NotFound is returned by API methods if the requested item does not exist.

Functions

This section is empty.

Types

type CallMsg

type CallMsg struct {
	From     common.Address  // the sender of the 'transaction'
	To       *common.Address // the destination contract (nil for contract creation)
	Gas      uint64          // if 0, the call executes with near-infinite gas
	GasPrice *big.Int        // wei <-> gas exchange ratio
	Value    *big.Int        // amount of wei sent along with the call
	Data     []byte          // input data, usually an ABI-encoded contract method invocation
}

CallMsg contains parameters for contract calls.

type ChainReader

type ChainReader interface {
	BlockByHash(ctx context.Context, hash common.Hash) (*types.Block, error)
	BlockByNumber(ctx context.Context, number *big.Int) (*types.Block, error)
	HeaderByHash(ctx context.Context, hash common.Hash) (*types.Header, error)
	HeaderByNumber(ctx context.Context, number *big.Int) (*types.Header, error)
	TransactionCount(ctx context.Context, blockHash common.Hash) (uint, error)
	TransactionInBlock(ctx context.Context, blockHash common.Hash, index uint) (*types.Transaction, error)

	// This method subscribes to notifications about changes of the head block of
	// the canonical chain.
	SubscribeNewHead(ctx context.Context, ch chan<- *types.Header) (Subscription, error)
}

ChainReader provides access to the blockchain. The methods in this interface access raw data from either the canonical chain (when requesting by block number) or any blockchain fork that was previously downloaded and processed by the node. The block number argument can be nil to select the latest canonical block. Reading block headers should be preferred over full blocks whenever possible.

The returned error is NotFound if the requested item does not exist.

type ChainStateReader

type ChainStateReader interface {
	BalanceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (*big.Int, error)
	StorageAt(ctx context.Context, account common.Address, key common.Hash, blockNumber *big.Int) ([]byte, error)
	CodeAt(ctx context.Context, account common.Address, blockNumber *big.Int) ([]byte, error)
	NonceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (uint64, error)
}

ChainStateReader wraps access to the state trie of the canonical blockchain. Note that implementations of the interface may be unable to return state values for old blocks. In many cases, using CallContract can be preferable to reading raw contract storage.

type ChainSyncReader

type ChainSyncReader interface {
	SyncProgress(ctx context.Context) (*SyncProgress, error)
}

ChainSyncReader wraps access to the node's current sync status. If there's no sync currently running, it returns nil.

type ContractCaller

type ContractCaller interface {
	CallContract(ctx context.Context, call CallMsg, blockNumber *big.Int) ([]byte, error)
}

A ContractCaller provides contract calls, essentially transactions that are executed by the EVM but not mined into the blockchain. ContractCall is a low-level method to execute such calls. For applications which are structured around specific contracts, the abigen tool provides a nicer, properly typed way to perform calls.

type FilterQuery

type FilterQuery struct {
	FromBlock *big.Int         // beginning of the queried range, nil means genesis block
	ToBlock   *big.Int         // end of the range, nil means latest block
	Addresses []common.Address // restricts matches to events created by specific contracts

	// The Topic list restricts matches to particular event topics. Each event has a list
	// of topics. Topics matches a prefix of that list. An empty element slice matches any
	// topic. Non-empty elements represent an alternative that matches any of the
	// contained topics.
	//
	// Examples:
	// {} or nil          matches any topic list
	// {{A}}              matches topic A in first position
	// {{}, {B}}          matches any topic in first position, B in second position
	// {{A}}, {B}}        matches topic A in first position, B in second position
	// {{A, B}}, {C, D}}  matches topic (A OR B) in first position, (C OR D) in second position
	Topics [][]common.Hash
}

FilterQuery contains options for contract log filtering.

type GasEstimator

type GasEstimator interface {
	EstimateGas(ctx context.Context, call CallMsg) (uint64, error)
}

GasEstimator wraps EstimateGas, which tries to estimate the gas needed to execute a specific transaction based on the pending state. There is no guarantee that this is the true gas limit requirement as other transactions may be added or removed by miners, but it should provide a basis for setting a reasonable default.

type GasPricer

type GasPricer interface {
	SuggestGasPrice(ctx context.Context) (*big.Int, error)
}

GasPricer wraps the gas price oracle, which monitors the blockchain to determine the optimal gas price given current fee market conditions.

type LogFilterer

type LogFilterer interface {
	FilterLogs(ctx context.Context, q FilterQuery) ([]types.Log, error)
	SubscribeFilterLogs(ctx context.Context, q FilterQuery, ch chan<- types.Log) (Subscription, error)
}

LogFilterer provides access to contract log events using a one-off query or continuous event subscription.

Logs received through a streaming query subscription may have Removed set to true, indicating that the log was reverted due to a chain reorganisation.

type PendingContractCaller

type PendingContractCaller interface {
	PendingCallContract(ctx context.Context, call CallMsg) ([]byte, error)
}

PendingContractCaller can be used to perform calls against the pending state.

type PendingStateEventer

type PendingStateEventer interface {
	SubscribePendingTransactions(ctx context.Context, ch chan<- *types.Transaction) (Subscription, error)
}

A PendingStateEventer provides access to real time notifications about changes to the pending state.

type PendingStateReader

type PendingStateReader interface {
	PendingBalanceAt(ctx context.Context, account common.Address) (*big.Int, error)
	PendingStorageAt(ctx context.Context, account common.Address, key common.Hash) ([]byte, error)
	PendingCodeAt(ctx context.Context, account common.Address) ([]byte, error)
	PendingNonceAt(ctx context.Context, account common.Address) (uint64, error)
	PendingTransactionCount(ctx context.Context) (uint, error)
}

A PendingStateReader provides access to the pending state, which is the result of all known executable transactions which have not yet been included in the blockchain. It is commonly used to display the result of ’unconfirmed’ actions (e.g. wallet value transfers) initiated by the user. The PendingNonceAt operation is a good way to retrieve the next available transaction nonce for a specific account.

type StateReader added in v1.1.1

type StateReader interface {
	State() (*state.StateDBManage, error)
	StateAt(root []common.CoinRoot) (*state.StateDBManage, error)
	//StateAtNumber(number uint64) (*state.StateDBManage, error)
	StateAtBlockHash(hash common.Hash) (*state.StateDBManage, error)
}

type Subscription

type Subscription interface {
	// Unsubscribe cancels the sending of events to the data channel
	// and closes the error channel.
	Unsubscribe()
	// Err returns the subscription error channel. The error channel receives
	// a value if there is an issue with the subscription (e.g. the network connection
	// delivering the events has been closed). Only one value will ever be sent.
	// The error channel is closed by Unsubscribe.
	Err() <-chan error
}

Subscription represents an event subscription where events are delivered on a data channel.

type SyncProgress

type SyncProgress struct {
	StartingBlock uint64 // Block number where sync began
	CurrentBlock  uint64 // Current block number where sync is at
	HighestBlock  uint64 // Highest alleged block number in the chain
	PulledStates  uint64 // Number of state trie entries already downloaded
	KnownStates   uint64 // Total number of state trie entries known about
}

SyncProgress gives progress indications when the node is synchronising with the Matrix network.

type TransactionReader

type TransactionReader interface {
	// TransactionByHash checks the pool of pending transactions in addition to the
	// blockchain. The isPending return value indicates whether the transaction has been
	// mined yet. Note that the transaction may not be part of the canonical chain even if
	// it's not pending.
	TransactionByHash(ctx context.Context, txHash common.Hash) (tx *types.Transaction, isPending bool, err error)
	// TransactionReceipt returns the receipt of a mined transaction. Note that the
	// transaction may not be included in the current canonical chain even if a receipt
	// exists.
	TransactionReceipt(ctx context.Context, txHash common.Hash) (*types.Receipt, error)
}

TransactionReader provides access to past transactions and their receipts. Implementations may impose arbitrary restrictions on the transactions and receipts that can be retrieved. Historic transactions may not be available.

Avoid relying on this interface if possible. Contract logs (through the LogFilterer interface) are more reliable and usually safer in the presence of chain reorganisations.

The returned error is NotFound if the requested item does not exist.

type TransactionSender

type TransactionSender interface {
	SendTransaction(ctx context.Context, tx *types.Transaction) error
}

TransactionSender wraps transaction sending. The SendTransaction method injects a signed transaction into the pending transaction pool for execution. If the transaction was a contract creation, the TransactionReceipt method can be used to retrieve the contract address after the transaction has been mined.

The transaction must be signed and have a valid nonce to be included. Consumers of the API can use package accounts to maintain local private keys and need can retrieve the next available nonce using PendingNonceAt.
