##Current version 1.8.27-atlantis

Go GUBET

The GUBET protocol is implemented in Golang and uses same Ethash algorithm as Ethereum blockchain.

Building UbetscoinGo client requires both a Go (version 1.8 or later) and a C compiler.

Build instructions for Mac

Clone the repository to a directory of your choosing:

git clone https://github.com/ubetprotocol/go-ubetprotocol

Building UbetscoinGo requires the Go compiler:

brew install go

Finally, build the UbetscoinGo program using the following command.

cd go-ubetprotocol
make gubet

If you see some errors related to header files of Mac OS system library, install XCode Command Line Tools, and try again.

xcode-select --install

You can now run build/bin/gubet to start your node.

You can also run sudo cp ./build/bin/gubet /usr/local/bin/gubet and then run gubet from any directory.

go-ubetprotocol client will now start downloading blocks. Wait till your node synchronises with the network to start activities such as mining.

Build instructions for Windows

The Chocolatey package manager provides an easy way to get the required build tools installed. If you don't have chocolatey yet, follow the instructions on https://chocolatey.org to install it first.

Then open an Administrator command prompt and install the build tools we need:

C:\Windows\system32> choco install git
C:\Windows\system32> choco install golang
C:\Windows\system32> choco install mingw

Installing these packages will set up the Path environment variable. Open a new command prompt to get the new Path. The following steps don't need Administrator privileges.

Please ensure that the installed Go version is 1.8 (or any later version).

First we'll create and set up a Go workspace directory layout, then clone the source.

OBS If, during the commands below, you get the following message:

 WARNING: The data being saved is truncated to 1024 characters.

Then that means that the setx command will fail, and proceeding will truncate the Path/GOPATH. If this happens, it's better to abort, and try to make some more room in Path before trying again.

C:\Users\xxx> set "GOPATH=%USERPROFILE%"
C:\Users\xxx> set "Path=%USERPROFILE%\bin;%Path%"
C:\Users\xxx> setx GOPATH "%GOPATH%"
C:\Users\xxx> setx Path "%Path%"
C:\Users\xxx> mkdir src\github.com\Ubetscoin
C:\Users\xxx> git clone https://github.com/ubetprotocol/go-ubetprotocol
C:\Users\xxx> cd go-ubetprotocol
C:\Users\xxx> go get -u -v golang.org/x/net/context

Finally, the command to compile Ubetgo-ubetprotocol is:

C:\Users\xxx\src\github.com\ubetprotocol/go-ubetprotocol> go install -v ./cmd/go-ubetprotocol

You can now run build/bin/gubet.exe to start your node.

go-ubetprotocol client will now start downloading blocks. Wait till your node synchronises with the network to start activities such as mining.

Build instructions for Ubuntu

Clone the repository to a directory of your choosing:

git clone https://github.com/ubetprotocol/go-ubetprotocol

Install latest distribution of Go (v1.8) if you don't have it already.

Building ubetprotocol requires Go and C compilers to be installed:

sudo apt-get install -y build-essential golang

Finally, build the ubetprotocol program using the following command.

cd go-ubetprotocol
make gubet

You can now run build/bin/gubet to start your node.

You can also run sudo cp ./build/bin/gubet /usr/local/bin/gubet and then run gubet from any directory.

ubetprotocol client will now start downloading blocks. Wait till your node synchronises with the network to start activities such as mining.

Programatically interfacing UbetscoinGo nodes

ubetprotocol has built in support for a JSON-RPC based APIs. These can be exposed via HTTP, WebSockets and IPC (unix sockets on unix based platforms, and named pipes on Windows).

The IPC interface is enabled by default and exposes all the APIs supported by ubetprotocol, whereas the HTTP and WS interfaces need to manually be enabled and only expose a subset of APIs due to security reasons. These can be turned on/off and configured as you'd expect.

HTTP based JSON-RPC API options:

--rpc Enable the HTTP-RPC server
--rpcaddr HTTP-RPC server listening interface (default: "localhost")
--rpcport HTTP-RPC server listening port (default: 8545)
--rpcapi API's offered over the HTTP-RPC interface (default: "eth,net,web3")
--rpccorsdomain Comma separated list of domains from which to accept cross origin requests (browser enforced)
--ws Enable the WS-RPC server
--wsaddr WS-RPC server listening interface (default: "localhost")
--wsport WS-RPC server listening port (default: 8546)
--wsapi API's offered over the WS-RPC interface (default: "eth,net,web3")
--wsorigins Origins from which to accept websockets requests
--ipcdisable Disable the IPC-RPC server
--ipcapi API's offered over the IPC-RPC interface (default: "admin,debug,eth,miner,net,personal,shh,txpool,web3")
--ipcpath Filename for IPC socket/pipe within the datadir (explicit paths escape it)

You'll need to use your own programming environments' capabilities (libraries, tools, etc) to connect via HTTP, WS or IPC to a ubetprotocol node configured with the above flags and you'll need to speak JSON-RPC on all transports. You can reuse the same connection for multiple requests!

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 {
	BlockHash *common.Hash     // used by eth_getLogs, return logs only from block with this hash
	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 AND B in second position
	// {{A}, {B}}         matches topic A in first position AND B in second position
	// {{A, B}, {C, D}}   matches topic (A OR B) in first position AND (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 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 Ubetprotocol 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.
