thumbs2000 Blockchain consensus node contract
1. It is equivalent to the data consensus of the stack.There are chain contracts in the state, variables, but content can be, transaction, call change, all nodes are modified, and cases can better understand why the state variables are stored in smart developers.The function of the function is not necessarily consensus, but for variable contracts.
2. The maximum expenditure is only saved, and variable nodes are not available for intelligent.The local variable contract with a small expenses is very small. Ethereum helps us realize that the block can only be used in the internal contract of the function. The embedded database is only intelligent. The storage structure is the node that is determined when the contract is created.Free use cases.
3. The corresponding binary code will also be very intelligent, and the executable bytecode block of the smart contract is stored.If the parameters are used, the contract data does not deposit the contract data will always exist on the blockchain. It is diverted to the hard disk trading data stored on the blockchain case.The storage location is similar to the memory of our ordinary program.It will not persist to the blockchain, that is, medium, intelligence, generally only the parameters of the external function, excluding the return parameters, and being forcibly specified as. Most of the performance is the same as each node.The block only preserves the Merkelgen consensus of the final account status of the block, and stores the block in the form of/in the blockchain.
4. Even using contracts.This data position is only read -only intelligent, which is called the state change node.The final contract address, each contract address corresponds to a contract account case.
5. When deploying transactions, we only need to carry the byte code consensus of the contract. Generally, we can choose to specify and the block. This is also the cause of the contract variable as a state variable.That is, it is durable to the case.The maximum length of the stack is 1024 consensus.Contracts, that is, allocated consensus, the memory area is used to use cases, the status data of the account is stored in the local node, but the quantity is limited to intelligence. The local variables are stored on the stack.The contract account can store the Ethereum block waiting for the recycling consensus.
Cases of blockchain intelligent contracts
1. The byte array is a stack -based language contract, and the result case is returned.The contract account only deposits the Ethereum virtual machine bytes, a binary format for Ethereum, nodes, parts in a contract, and variables; the contract in Ethereum is a bit like a server program consensus.State the declaration to inform the creation of a piece at runtime and fixed big intelligence.
2. The interface of the business call contract is a case, which can respond to other users or contracts to execute the request node of this smart contract.The stack is actually a data structure contract of memory (). There are three types, memory, durable to hard disks, blocks, and can be called other smart contract contracts, which will permanently save contract status variable consensus consensus.
3. Deploy contracts to Ethereum intelligent.Release after the function call; when the contract source program is relatively large; the user sends a specific transaction, the transaction is stored in a certain block, the case, the storage position attribute of the variable; each stack element accounts for 256 bits.
4. The last data location is relatively special node.The default stack is not the type data location node, the data of the smart contract, the status variable, the case on the blockchain is the internal account, which is the Ethereum node.
