Technical description of the platform

Description of transactions

The Waves Enterprise blockchain platform supports 28 types of transactions. Each of them contains its own set of data to be sent into the blockchain.

Requests and responses passed via the node REST API interface within the framework of each transaction, have JSON format. Requests and responses passed via the node gRPC interface, are defined by corresponding proto schemes. JSON models of transaction requests and responses are stated below.

Hint

In case you have protected the keypair of your node with a password while generating the account, set the password of your keypair in the password field of a transaction.

1. Genesis Transaction

First transaction of a new blockchain which performs first attachment of balance to addresses of created nodes.

This transaction does not require signing, that is why it is only broadcasted. Transaction has the only version.

8. Lease Transaction

Leasing of tokens to another address. The tokens in leasing are taken into account in the generating balance of a recipient after 1000 blocks.

Leasing of tokens can be carried out for increasing of probability of node appointment as a next round miner. As a rule, a recipient shares his revenue for block generation with an address which has granted him tokens for leasing.

Tokens in leasing remain blocked at a sender address. Leasing can be cancelled with the use of leasing cancel transaction.

10. CreateAlias Transaction

Creation of an alias for a sender address. An alias can be used in transactions as a recipient identifier.

The 3rd version of the transaction implemented the ability to pay fee in another token. The 4th version of the transaction features the ability to include the transaction in a atomic transaction.

12. Data Transaction

Transaction for adding, editing and removing of entries in an address data storage. An address data storage contains data in the ‘key:value’ format.

The size of the address data repository is unlimited, but up to 100 new “key:value” pairs can be added with a single data transaction. Also the byte representation of the transaction after signing must not exceed 150 kilobytes.

If the data author (the address in the author field) matches the transaction sender (the address in the sender field), the senderPublicKey parameter is not required when signing the transaction.

Version 4

The 4th version of this transaction configures validation of the execution results of the updated smart contract using the validationPolicy.type field (see section Validation of smart contracts).

Variants of validation policies:
  • any - the general validation policy is kept in the network: to mine the updated smart contract, the miner signs the corresponding 105 transaction. Also, this parameter is set if there are no registered validators in the network.

  • majority - a transaction is considered valid if it is confirmed by the majority of validators: 2/3 of the total number of registered addresses with the contract_validator permission.

  • majorityWithOneOf(List[Address]) - the transaction is considered valid if the majority of validators is collected, among which there is at least one of the addresses included in the parameter list. The addresses included in the list must have a valid contract_validator permission.

Warning

If you select the majorityWithOneOf(List[Address]) validation policy, fill the address list. Passing an empty list is not allowed.

Version 5

In the version 5 of this transaction a user can transfer his assets to the balance of a contract. To do this, an array of assets and their number are specified in the payments field. Both the system WEST token and any other asset created in the network can be transferred. Version 5 of this transaction can be used starting from release 1.12 after the 1120 feature activation.

In private networks, the 103 transaction allows to install Docker images of smart contracts from repositories other than those stated in the docker-engine section of the node configuration file.

If you need to install a smart contract from a registry not included in the list in the node configuration file, specify the full address of the smart contract in the registry you have created in the name field of the 103 transaction.

Example of a request to publish a smart contract from a repository not specified in the node configuration file:

Version 6

Version 6 of this transaction implements support for confidential smart contracts. When registering a contract using the 6th version of the transaction, you can specify if the contract is confidential, and define a set of node addresses that have access to the smart contract confidential data. The following fields are implemented for this purpose:

Fields for working with confidential smart contracts:

The following fields are implemented for this purpose:

  • the isConfidential flag determines whether the smart contract is confidential or not;

  • the groupParticipants field specifies the group (policy) member nodes who have access to confidential smart-contract data; the maximum group size is 1024 members;

  • the groupOwners field specifies the nodes that can modify the groupParticipants and groupOwners lists using the UpdateContract transaction; no more than 1024 nodes can be specified in this field.

Important

You cannot assign true to the isConfidential field when creating a contract if the groupParticipants field contains less than three participants with the contract-validator role.

You cannot assign false to the isConfidential field when creating a contract if the groupParticipants and groupOwners fields are not empty.

You cannot assign any value to the payments field when creating a contract if the isConfidential field is set to true.

You cannot pass parameters to the params field when creating a contract if the isConfidential field is set to true.

You can use the 6 th version of this transaction starting with 1.13 release after the 1130 feature activation.

Version 7 – Create WASM Contract Transaction

In version 7 of this transaction, support for WASM smart contracts is implemented. For this purpose image, imageHash, apiVersion fields are removed and storedContract field is implemented. Depending on the type of smart contract, this field has the following structure:

  • for Docker smart contracts:

    "storedContract" : {
       "image" : <image docker> in Array[Byte]
       "imageHash": ssh256 from the image docker
       "apiVersion" : "1.10",
    }
    
  • for WASM smart contracts:

    "storedContract" : {
       "bytecode" : <bytecode contracts> in Array[Byte]
       "bytecodeHash" : "Sha256 from the <bytecode contracts>"
    }
    

You can use the version 7 of this transaction starting with release 1.14.0 after 1140 feature activation.

Important

In release 1.14.0, WASM smart contracts do not support atomic transactions and confidential smart contracts. Therefore, the following fields must have the following values for a WASM smart contract:

...
"atomicBadge" : null,
...
"isConfidential": false,
"groupParticipants": [],
"groupOwners": [],
...

104. CallContract Transaction

Transaction calling a smart contract for execution. The byte representation of this transaction after it is signed must not exceed 150 kilobytes.

Signing of the transaction is performed by the initiator of the contract execution.

The contractVersion field of the transaction specifies the contract version:

  • 1 – for a new contract;

  • 2 – for an updated contract.

This field is only available for the transaction of the second version and higher: if the version field of the smart contract call transaction is set to 2 or more. The contract is updated using the 107 transaction.

Prior to release 1.14.0, if a contract was not executed or was executed with an error, 103 and 104 transactions were deleted and not included into a block. Starting with release 1.14.0, execution of a smart contract in case of an error is also stored in the blockchain. For more details on the smart contract error handling algorithm, see 105.

Version 5

In the version 5 of this transaction a user can transfer his assets to the balance of a contract. To do this, an array of assets and their number are specified in the payments field. Both the system WEST token and any other asset created in the network can be transferred. Version 5 of this transaction can be used starting from release 1.12 after the 1120 feature activation.

Version 6

Version 6 of this transaction implements the field required to handle confidential smart contracts.

The use of version 6 of this transaction is possible starting from release 1.13 after 1130 feature activation. After the 1130 feature activation, only version 6 of the transaction is used in the network.

Version 7

Version 7 of this transaction supports WASM smart contracts. The following fields are implemented for this purpose:

  • contractEngine – defines the type of contract to be called; available values:

    • wasm

    • docker

  • callFunc – the name of the WASM smart contract function to be called; the _constructor function cannot be specified in this field, as it is only called when the contract is created; for a Docker smart contract, the field must be left empty: callFunc: null.

    Attention

    The order and type of parameters passed to the function is important: in the params field of the JSON to be signed, the parameters must be specified exactly in the order in which the function specified in the callFunc field expects them.

You can use the version 7 of this transaction starting with release 1.14.0 after 1140 feature activation.

Important

In release 1.14.0, WASM smart contracts do not support atomic transactions and confidential smart contracts. Therefore, for a WASM smart contract, the inputCommitmentOpt field must be absent and the atomicBadge field must be absent or set to null in the JSON to be signed.

105. ExecutedContract Transaction

Transaction writing smart contract execution result to its state. The byte representation of this transaction after signing must not exceed 150 kilobytes.

105 Transaction contains all the fields (body) of the 103. CreateContract, 104. CallContract, 107. UpdateContract transaction of the smart contract whose execution result must be written to its state (the tx field). The smart contract execution result is entered into its state from the corresponding parameters of the params field of 103 or 104 transaction.

The transaction is signed by the node that forms the block after sending the request to publish the transaction.

Long

The Unix Timestamp of the transaction (in milliseconds) – optional field

proofs

List(ByteStr)

Array of transaction proofs (in base58 format)

version

Byte

Transaction version

tx

Array

Body of transaction 103 or 104 of an executed smart contract

results

List[DataEntry[_]]

List of possible results of smart contract execution; the field is used up to and including version 4 of the transaction; from version 5 onwards, the resultsMap field is used instead

resultsMap

Map[ByteStr, List]

A set of lists of possible results of smart contracts execution; the field is used since version 5; earlier versions use the results field instead

height

Byte

Height of the transaction execution – an optional field

assetOperations

A structured list of the smart contract actions with the assets available to it, including
  • issuing a new asset,

  • reissuing an asset,

  • burning an asset,

  • transferring an asset available to the contract to another user,

  • leasing an asset available to the contract to another user,

  • cancelling of leasing of tokens that have been leased before

The field is used up to and including version 4 of the transaction; starting with version 5, the assetOperationsMap field is used instead

assetOperations.operationType

A service field that represents the operation type. The field can take the following values:

issue, reissue, burn, transfer, lease, cancel-lease

assetOperations.version

Service field representing the object version

assetOperations.assetId

When issuing assets, the field value is calculated using the gRPC method CalculateAssetId of the ContractService.

When reissuing or burning an asset, the identifier determines which token is being reissued or burned.

When transferring an asset, the identifier determines which asset is being transferred.

In the case of sending the WEST system token, the assetId field must be omitted or equal to null.

assetOperations.name

Asset name

assetOperations.description

Asset description

assetOperations.quantity

When issuing an asset, the field specifies the total amount of the issued asset.

When reissuing an asset – the amount of the reissued asset

assetOperations.decimals

When issuing assets, the field specifies the number of decimal places of the asset being issued

assetOperations.isReissuable

The flag indicating if the asset can be reissued

assetOperations.nonce

When issuing asserts, the field value is used to calculate the assetId. It cannot be equal to 0.

The range of acceptable values is from -128 to 127.

Several assets with the same nonce cannot be released within one contract call

assetOperations.amount

When burning assets, the field specifies the amount of asset to be burned.

When transferring assets, the field specifies the amount of the transferred asset

assetOperations.recipient

When transferring assets, the field specifies the address of the user to whom the contract transfers the assets

assetOperationsMap

Map[ByteStr, List]

The field is similar to the assetOperations field, and is used since version 5 of the transaction

readings

ReadDescriptor

The field is used to handle confidential smart contracts and describes the public data reading order on the contract side

readingsHash

ByteStr

The field is used to handle confidential smart contracts and represents a hash of readings and the results of the readings. The field has a fixed length

outputCommitment

Commitment

The field is used in transaction version 4 to handle confidential smart contracts. Field length is a constant equal to hash length in current cryptography

outputCommitmentOpt

Commitment

The field is used in transaction version 5 and is similar to the outputCommitment field – optional field

statusCode

Integer

The execution status of the smart contract. The following values are available: 0, 1, 2

errorMessage

Version 3

In the version 3 of this transaction you can pass a sequence of operations on assets, such as transferring tokens from the user balance to the contract balance, in the assetOperations field.

  • Both the WEST system token and any other asset created on the network can be transferred using the transfer operation.

  • The issue, reissue, burn operations can be performed with any token except the WEST system token.

  • The lease and cancel-lease operations work only with the WEST system token.

Important

If the isReissuable field is set to False, i.e. tokens are not allowed to be reissued, then it will be impossible to change this value in the future.

The version 3 of this transaction can be used starting with the 1.12 release after the 1120 feature activation. After the 1120 feature activation, only version 3 of this transaction is used on the network.

You can use the lease and cancel-lease operations starting from release 1.12.3 after the 1123 feature activation.

Version 4

Version 4 of this transaction implements the fields required to handle confidential smart contracts.

The use of version 4 of this transaction is possible starting from release 1.13 after 1130 feature activation. After the 1130 feature activation, only version 4 of the transaction is used in the network.

Version 5

In version 5 of this transaction, the algorithm for handling smart contract errors has been changed:

  • In case of successful execution, the node (as in the previous versions) generates and sends to the blockchain a 105 transaction, which contains the details of the change to the state within the original 103 or 104 transaction in the following format:

    "results": [
      {
        "type": "string",
        "value": "[{\"accountNumber\":\"1119810\"}]",
        "key": "accounts"
      }
    ]
    
  • In case of an error, transaction 105 is also generated, and the smart contract execution with the error is stored in the blockchain when the transaction reaches a quorum.

This version of the transaction implements the fields required to capture smart contract execution statuses:

  • statusCode – smart contract execution status; the following values are available:

    • 0 – Success – successful contract execution; the intended result was obtained;

    • 1 – Error – business logic error; the contract ended in error, but may end successfully in the future;

    • 2 – Failure – system error; a blockchain component has failed, such as in the case of a timeout.

  • errorMessage – error description; in the case of a WASM smart contract, the field contains error code; in the case of a Docker smart contract, a user-defined error or other error is returned.

In addition, data from multiple smart contracts can now be transferred in a single transaction. Whereby the fields have changed as follows:

  • the results field has been replaced by a resultsMap field, which can pass a list of results for each of the smart contracts;

  • the assetOperations field is replaced by the assetOperationsMap field. A number of ordered lists of smart contract actions over the assets available to them can be passed in this field.

You can use version 5 of this transaction starting with release 1.14.0 after 1140 feature activation.

106. DisableContract Transaction

Disabling a smart contract.

Important

The transaction is irreversible, that is, the disabled contract cannot be used thereafter under any conditions.

The byte representation of this transaction after it is signed must not exceed 150 kilobytes.

Transaction 106 can only be signed by a user with the contract_developer role.

Version 4

The 4th version of this transaction configures validation of the execution results of the updated smart contract using the validationPolicy.type field (see section Validation of smart contracts).

Fields to configure smart contract validation:

Variants of validation policies:

  • any - the general validation policy is kept in the network: to mine the updated smart contract, the miner signs the corresponding 105 transaction. Also, this parameter is set if there are no registered validators in the network.

  • majority - a transaction is considered valid if it is confirmed by the majority of validators: 2/3 of the total number of registered addresses with the contract_validator permission.

  • majorityWithOneOf(List[Address]) - the transaction is considered valid if the majority of validators is collected, among which there is at least one of the addresses included in the parameter list. The addresses included in the list must have a valid contract_validator permission.

Warning

In case of using the majorityWithOneOf(List[Address]) validation policy, fill the address list, passing an empty list is not allowed.

Version 5

Version 5 of this transaction implements the fields required to handle confidential smart contracts.

Fields for working with confidential smart contracts:
  • the groupParticipants field specifies the group (policy) member nodes who have access to confidential smart-contract data; the maximum group size is 1024 members;

  • the groupOwners field specifies the nodes that can modify the groupParticipants and groupOwners lists using the UpdateContract transaction; no more than 1024 nodes can be specified in this field.

Only the sender of the UpdateContract transaction, whose address is specified in the groupOwners field, can change the values of the groupParticipants and groupOwners fields.

The contract creator can modify the contract itself (the image, imageHash and apiVersion fields), but he must have his address listed in the groupOwners field to be able to modify the groupParticipants and groupOwners fields.

The group owner (the address listed in the groupOwners field) cannot modify the contract, that is the image, imageHash and apiVersion fields.

The groupParticipants and groupOwners fields must be empty if the isConfidential parameter was set to false when the contract was created.

Important

You cannot update a contract if its isConfidential parameter was set to true when it was created, and the groupParticipants field contains less than 3 participants with the contract-validator role.

You can use the 5 th version of this transaction starting with 1.13 release after the 1130 feature activation.

Version 6

Support for WASM smart contracts is implemented in version 6 of this transaction. For this purpose image, imageHash, apiVersion fields are removed and storedContract field is implemented:

  • for Docker smart contracts:

    "storedContract" : {
       "image" : String
       "imageHash": String
       "apiVersion" : Byte,
    }
    
  • For WASM smart contracts:

    "storedContract" : {
       "bytecode" : <bytecode contracts>
       "bytecodeHash" : "Sha256 от <bytecode contracts>"
    }
    

Important

A Docker smart contract cannot be updated to a WASM smart contract.

You can use the version 6 of this transaction starting with release 1.14.0 after 1140 feature activation.

Important

In release 1.14.0, WASM smart contracts do not support atomic transactions and confidential smart contracts. Therefore, for a WASM smart contract, the atomicBadge field must be absent from the JSON for signing, or have the value of null; also the following fields must have the following values:

...
"groupParticipants": [],
"groupOwners": [],
...

120. Atomic Transaction

Atomic transaction sets other transactions in a container for their atomic execution. This transaction can be executed only in full (no transactions have been declined), in other cases it will not be executed.

You can include two or more transactions into an atomic transaction. Transaction types and versions that can be included in an atomic transaction are listed in the Atomic transactions section; this article also provides more detailed information about processing this type of transactions.

An atomic transaction itself does not require a fee: its total fee is summed up from fee of transactions included into it.
