Blockchain transaction pending clash
A blockchain transaction pending clash is a collection of code its functions and data its state that resides at a specific address on the Expanse blockchain. Contract accounts are able to pass messages between themselves as well as doing practically Turing complete computation.
Contracts are typically written in some high level language such as Solidity and then compiled into bytecode to be uploaded on the blockchain. Other languages also exist, notably Serpent and LLL, which are described further in the expanse-high-level-languages section of this documentation. Dapp development resources lists the integrated development environments, developer tools that help you develop in these languages, offering testing, and deployment support among other features.
However, contracts are typically written in a higher level language and then compiled using the EVM compiler into byte code to be deployed to the blockchain. Below are the different high level languages developers can use to write smart contracts for Expanse. Solidity is a language similar to JavaScript which allows you to develop contracts and compile to EVM bytecode. It is currently the flagship language of Expanse and the most popular.
Serpent is a language similar to Python which can be used to develop contracts and compile to EVM bytecode. It is intended to be maximally clean and simple, combining many of the efficiency benefits of a low-level language with ease-of-use in programming style, and at the same time adding special domain-specific features for contract programming.
Serpent is compiled using LLL. It is meant to be very simple and minimalistic; essentially just a tiny wrapper over coding in EVM directly.
Mutan is a statically typed, C-like language designed and developed by Jeffrey Wilcke. It is no longer maintained. No language would be complete without a Hello World program. The closest we can do is to use a log event to place a string into the blockchain:. Solidity docs has more examples and guidelines to writing Solidity code. More blockchain transaction pending clash on solc and compiling Solidity contract code can be found here.
If you start up your gexp node, you can check which compilers are available. The solc compiler is installed with cpp-expanse. Alternatively, you can build it yourself. If your solc executable is in a non-standard location you can specify a custom path to the solc executable using th --solc flag. You are ready to compile solidity code in the gexp JS console using exp. The compiler is also available via RPC and therefore via web3. The compiler output for one source will give you contract objects each representing a single contract.
The actual return value of exp. The immediate structuring of the compiler output into code and info reflects the two very different paths of deployment. The compiled EVM code is sent off to the blockchain with a contract creation transaction while the rest info will ideally live on the decentralised cloud as publicly verifiable metadata complementing the code on the blockchain. If your source contains multiple contracts, the output will contain blockchain transaction pending clash entry for each contact, the corresponding contract info object can be retrieved with the name of the contract as attribute name.
You can try this by inspecting the most current GlobalRegistrar code:. Before you begin this section, make sure you have both an unlocked account as well as some funds. You will now create a contract on the blockchain by sending a transaction to the empty address with the EVM code from the previous section as data. This can be accomplished much easier using the online Solidity realtime compiler or the Mix IDE program. All binary data is serialised in hexadecimal form.
Hex strings always have a hex prefix 0x. Note that arg1, arg2, If the contract does not require any constructor arguments then these arguments can be omitted. It is worth pointing out that this step requires you to pay for execution. Your balance on the account that you put as sender in the from field will be reduced according to the gas rules of the EVM once your transaction makes it into a block.
After some time, your transaction should appear included in a block confirming that the state it brought about is a consensus. Your contract now lives on the blockchain. Interaction with a contract is typically done using an abstraction layer such as the exp. Blockchain transaction pending clash standard way to describe the available functions of a contract is the ABI definition. This object is an array which describles the call signature and return values for each available contract function.
Now all the function calls specified in the ABI are made available on the contract instance. You can just call those methods blockchain transaction pending clash the contract instance in one of two ways.
When called using blockchain transaction pending clash the function call is executed via sending a transaction. This will cost expanse to send and the call will be recorded forever on the blockchain. The return value of calls made in this manner is the hash of the stransaction. When called using call the function is executed locally in the EVM and the return value of the function is returned with the function. Calls blockchain transaction pending clash in this manner are not recorded on the blockchain and thus, cannot modify blockchain transaction pending clash internal state of the contract.
This manner of call is referred to as a constant function call. Calls made in this manner do not cost any expanse.
You should use call if you are interested only in the return value and use sendTransaction blockchain transaction pending clash you only care about side effects on the state of the contract.
In the example above, there are no side effects, therefore sendTransaction only burns gas and increases the entropy of the universe.
In the previous sections we explained how you create a contract on the blockchain. Now we will deal with the rest of the compiler output, the contract metadata or contract info. When interacting with a contract you did not create you might want documentation or to look at the source code.
Contract authors are encouraged to make such information available by registering it on the blockchain or through a third party service, such as EtherChain. The admin API provides convenience methods to fetch this bundle for any contract that chose to register.
These requirements are blockchain transaction pending clash using a 2 step blockchain transaction pending clash registry. The first step registers the contract code hash with a content hash in a contract called HashReg. The second step registers a url with the content hash in the UrlHint contract.
These registry contracts were part of the Frontier release and have carried on into Homestead. Once you deployed that file to any url, you can use admin. Note blockchain transaction pending clash in case a fixed content addressed model is used as document store, the url-hint is no longer necessary.
Often you need to resort to a low level strategy of testing and debugging contracts and transactions. This section introduces some debug tools and practices you can use. In order to test contracts and transactions without real-word consequences, you best test it on a private blockchain. It is recommended practice that for testing you use an alternative data directory and ports so that you never even accidentally clash with your live running node assuming that runs using the defaults.
Starting your gexp with in VM debug mode with profiling and highest logging verbosity level is recommended:. Before you can submit any transactions, you blockchain transaction pending clash set up your private test chain. If you submitted contract creation transaction, you can check if the desired code actually got inserted in the current blockchain:. See also Other languages also exist, notably Serpent and LLL, which are described further in the expanse-high-level-languages section of this documentation.
