Version 1.3.5 Jumeirah (Mainnet + Testnet + Stagenet)

In this release

This release is accumulation of all previous 1.3.x releases. Now it's available for Mainnet.
After the activation of the feature #​16 all Protocol changes become available.

Protocol Enhancements

• dApp-to-dApp invocation. A dApp callable function can invoke a callable function of another dApp, or another callable function of the same dApp, or even itself. All invoked functions are executed within a single Invoke Script transaction. The total complexity is limited. More about dApp-to-dApp invocation
• Amended Invoke Script transaction:
  • Canceled the extra fee of 0.004 WAVES for smart assets in payments and script actions.
  • Transaction can contain up to 10 attached payments.
  • The total complexity for all callable functions and asset scripts involved is limited by 26,000 (the sender's account script complexity is not included in this limit).
  • The maximum complexity of a callable function of a dApp script is changed to 10,000.
• For all types of transactions, canceled the extra fee of 0.004 WAVES for sending a transaction from a smart account or dApp unless the complexity of sender's account script or dApp script verifier function exceeds 200.

Ride

• Issued version 5 of the Ride Standard library.

• Enabled processing up to 10 payments attached to the Invoke Script transaction.

• Added the functions for dApp-to-dApp invocation:

  • invoke
  • reentrantInvoke

• Added strict variables that are evaluated before the next expression to ensure executing callable functions and applying their actions in the right order.

• Modified the callable function result by adding a return value.

• Modified the Invocation structure: in case of dApp-to-dApp invocation, the structure contains the address and public key of both the sender of the Invoke Script transaction and the dApp account that invokes the callable function.

• The maximum total number of Issue, Reissue, Burn, SponsorFee, ScriptTransfer, Lease, LeaseCancel script actions executed by all callable functions in a single transaction is 30.

• The maximum total number of BinaryEntry, BooleanEntry, IntegerEntry, StringEntry, DeleteEntry script actions executed by all callable functions in a single transaction is 100.

• Added script actions that the callable function can perform:

  • Lease — leases WAVES.
  • LeaseCancel — cancels a specified lease.

  Using these actions, you can change the amount of the lease, in particular, withdraw a part of the leased funds. If you cancel a lease for a larger amount and create a new lease for a smaller amount with the same recipient in the same script invocation, the recipient's generating balance decreases by the difference. Otherwise, if you send two separate transactions: a Lease Cancel transaction and a Lease transaction, they can be added to a different blocks and therefore generating balance decreases by the amount of the canceled lease immediately and increases by the amount of the new lease after 1000 blocks.

• Added the function calculateLeaseId that calculates ID of the lease formed by the Lease structure.

• Added an arbitrary data type — Any.

• Added the BigInt data type of 64 bytes (512 bits) and functions.

• Added the following built-in functions:

  • isDataStorageUntouched that checks if the data storage of a given account never contained any entries.
  • scriptHash that returns BLAKE2b-256 hash of the script assigned to a given account.
  • fraction(Int, Int, Int, Union): Int that multiplies and divides integers to avoid overflow, applying the specified rounding method.

• Added the following account data storage functions that allow the dApp script to read entries of its own data storage:

  • getBinary(key: String): ByteVector|Unit
  • getBinaryValue(key: String): ByteVector
  • getBoolean(key: String): Boolean|Unit
  • getBooleanValue(key: String): Boolean
  • getInteger(key: String): Int|Unit
  • getIntegerValue(key: String): Int
  • getString(key: String): String|Unit
  • getStringValue(key: String): String

• The maximum complexity of a callable function of a dApp script is changed to 10,000.

Node REST API

Breaking Changes

A lease can be created both as a result of a Lease transaction and as a result of an Invoke Script transaction via a Lease script action. Therefore, the response of the following endpoints has been changed:

• In the response of /transactions/address/{address}/limit/{limit} and /transactions/info/{id} endpoints for a Lease Cancel transaction, the lease structure now contains lease parameters instead of Lease transaction fields.
• /leasing/active/{address} returns an array of structures containing lease parameters instead of array of Lease transactions.

Semantic Changes

• dApp-to-dApp invocation results are added as the invokes array to the stateChanges structure returned by the following endpoints:

  • /transactions/info/{id}
  • /transactions/address/{address}/limit/{limit}

  Each element of invokes array, in turn, also contains stateChanges.

• Results of the Lease and LeaseCancel script actions are added to the stateChanges structure.

• Results of Lease and LeaseCancel script actions are also added to the trace structure returned by the following endpoints:

  • /transactions/broadcast
  • /debug/validate

Improvements

• Added the /leasing/info endpoint that returns lease parameters by lease IDs.
• Added the /blocks/heightByTimestamp endpoint that returns blockchain height at a given timestamp.

Activation

To activate the improvements listed above, vote for feature #16 “Ride V5, dApp-to-dApp invocations”.

Update Notes

If you are not using Blockchain Updates extension, there's no need to reimport state when updating from version 1.2.x.
Attention Blockchain Updates users:

• Due to an issue with one of the previous versions, current extension data is likely inconsistent with the blockchain. Please reimport blockchain to rebuild BU state.
• In some cases BU subscription can get stuck, that is once connected, the client receives some updates up to the most recent block/microblock, but won't receive any subsequent updates when node appends new blocks/microblocks. This is a known issue. While we are working on a fix, one possible workaround is to monitor the connection, and once the subscription is stuck, restart the node process.

Official pools update notes

Due to presense of breaking changes in the Node's API please migrate your existing projects/applications. Version 1.3.5 will be immediately available on the testnet. Mainnet will be updated on June, 11th.

Version 1.3.3 (Stagenet)

In this release

This release is intended for Stagenet only. There's no need to rebuild state when updating from 1.3.2

This release includes the following improvements:

• Added the reentrantInvoke function for dApp-to-dApp invocation. The only difference from the invoke function is that there is no reentrancy restriction for the parent dApp that uses reentrantInvoke.
• The maximum complexity of a callable function of a dApp script is changed to 10,000.
• Blockchain Updates stream no longer freezes upon microblock rollbacks.
• Updated nested invocation lease state changes format to be consistent with /leasing/info/{id} endpoint.

Version 1.3.2 (Stagenet)

In this release

This release is intended for Stagenet only. There's no need to rebuild state when updating from 1.3.1

RIDE Improvements

• Misc BigInt implementation fixes.
• Invocation structure has been enhanced with two additional fields: originCaller and originCallerPublicKey.

Node Improvements

• Fixed smart asset script estimation errors which could cause the eviction of valid transactions from UTX pool during cleanup.
• Active leases created by a nested invocation are returned by the /leasing/active/{address} method.
• New /blocks/height/{timestamp} method returns actual blockchain height at the given timestamp.
• New /leasing/info/{id} returns lease details for the given lease ID (even for those issued via invocations).
• State changes JSON has been tweaked to include invocation tree even for failed transactions, and also to make lease action details JSON consistent with lease info route response.
• The node will check if the newly received extension increases local score before attempting to append it.

Version 1.3.1 (Stagenet)

In this release

This release refines functionality introduced with release 1.3.0. Being intended for Stagenet only, it still has some known issues described below. To find out more about new functionality in series 1.3, head over to release notes.

Protocol Enhancements

• Increased block complexity limit from 1M to 2.5M, changed overall (including nested) invocation limits:
  • complexity can not exceed 26000
  • action limit has been increased to 30
  • data entry limit has been increased to 100
• Fixed complexity estimation for dApp-to-dApp calls.
• When dApp does not have enough balance to cover transfer actions produced by an invocation, such invocations are no longer discarded, and are included in the block as failed instead.
• Attached payment limit has been increased from 2 to 10 for invocations targeting dApps using RIDE V5.
• When account's @Verifier script complexity does not exceed 200, outgoing transactions from such accounts will not require additional fee.
• Continued сomputations have been pushed to release 1.4. All continuations-related functionality has been removed from this release.

RIDE

In addition to the features from v1.3.0, he following changes have been introduced with RIDE V5:

• New BigInt type widens built-in integer type to 512 bits.
• Invocation structure has been extended with originalCaller and originalCallerPublicKey fields which contain original InvokeScript transaction's sender address and public key.
• Added new functions:
  • isDataStorageUntouched that checks if the data storage of a given account never contained any entries.
  • hashScriptAtAddress that returns BLAKE2b-256 hash of the script assigned to a given account.
• Non-standard rounding modes HALFDOWN and UP have been removed.

Node

• Leases produced from nested dApp invocation will not be returned by /leasing/active/{address} API. This is a known issue which will be fixed in the upcoming version.
• Upon successful rollback completion, only those transactions which are not present in the blockchain will be returned to UTX pool.
• All fixes from 1.2.x series (up to [release 1.2.20]) have been backported to this series, which includes the new Blockchain Updates extension.

Version 1.2.20 (Mainnet + Testnet)

In this release

This release includes the new and improved version of the Blockchain Updates extension. If you are not using the extension with your node, or if you prefer to continue using the previous version, you may skip this version.

• The new updates stream enhances StateUpdate messages with the before values (e.g. BalanceUpdate message has a new amount_before field which contains the address balance preceding update application).
• Additional TransactionMetadata is supplied for each transaction. This message contains resolved recipient addresses for transfers directed to aliases, function invocation details and some other data which can not be retrieved from the transaction itself.
• Rollback messages are enhanced with state updates and transaction IDs which are being reverted. These fields contains the data which helps consumers more easily handle rollbacks.
  For more information on the new extension, see documentation.

Update notes

Please note that this Blockchain Updates extension version is incompatible with the previous versions (consumers working with previous extension versions will not be able to connect to this version). You will need to re-generate client stubs from schemas version 1.2.11 to use the new stream. We will be updating our Mainnet pool to the new version on Monday, March 29th.

Please also note that updating your extension from previous versions requires re-importing blockchain. This requirement is caused by redesigned extension data storage which no longer stores blocks in its own LevelDB, using the ones stored by the node itself. This greatly reduces storage space requirement for this extension (by as much as raw blockchain size — almost 43GB for Mainnet as of height 2515000). The extension itself consumes 32GB of storage space, in addition to the node's 55GB.

• Fixed an issue with Blockchain Updates extension which resulted in intermittent connectivity issues.
• Fixed /debug/validate method to respect priority pool when validating transactions.
• Fixed an off-by-one error in blocks/delay method.
• Changed the way docker images are built. See README for more info.

This is a maintenance release, you only need to update your node if any of the issues mentioned above affects you. There's no need to reimport state when updating from 1.2.18.

Version 1.3.0 (Stagenet)

Attention! This release is for stagenet only! Not for mainnet/testnet.

In this release

Protocol Enhancements

• dApp-to-dApp invocation. A dApp callable function can invoke a callable function of another dApp, or another callable function of the same dApp, or even itself. All invoked functions are executed within a single Invoke Script transaction. The total complexity is limited. More about dApp-to-dApp invocation
• Continued сomputations.
  • Added support for dApp scripts with complexity over 4000. The execution of such a script is split into several stages. The first stage of calculations is performed within the Invoke Script transaction. The further stages are performed within Continuation transactions. More about continued сomputations
  • Implemented the new transaction type: Continuation. A block generator creates the Continuation transaction if there is an incomplete calculation sequence. A user cannot send a Continuation transaction.
  • Added version 3 for the Invoke Script transaction that can invoke a script with complexity over 4000.

Ride

• Issued version 5 of the Ride Standard library.

• Added the Invoke function for dApp-to-dApp invocation.

• Added strict variables that are evaluated before the next expression to ensure executing callable functions and applying their actions in the right order.

• Modified the callable function result by adding a return value.

• Added script actions that the callable function can perform:

  • Lease — leases WAVES.
  • LeaseCancel — cancels a specified lease.

  Using these actions, you can change the amount of the lease, in particular, withdraw a part of the leased funds. If you cancel a lease for a larger amount and create a new lease for a smaller amount with the same recipient in the same script invocation, the recipient's generating balance decreases by the difference. Otherwise, if you send two separate transactions: a Lease Cancel transaction and a Lease transaction, they can be added to a different blocks and therefore generating balance decreases by the amount of the canceled lease immediately and increases by the amount of the new lease after 1000 blocks.

• Added the function calculateLeaseId that calculates ID of the lease formed by the Lease structure.

• Added the following account data storage functions that allow the dApp script to read entries of its own data storage at any stage of the calculations:

  • getBinary(key: String): ByteVector|Unit
  • getBinaryValue(key: String): ByteVector
  • getBoolean(key: String): Boolean|Unit
  • getBooleanValue(key: String): Boolean
  • getInteger(key: String): Int|Unit
  • getIntegerValue(key: String): Int
  • getString(key: String): String|Unit
  • getStringValue(key: String): String

• Added an arbitrary data type — Any.

Node REST API

Breaking Changes

• Added the new transaction type: Continuation.

• A lease can be created both as a result of a Lease transaction and as a result of an Invoke Script transaction via a Lease script action. Therefore, the response of the following endpoints has been changed:

  • In the response of /transactions/address/{address}/limit/{limit} and /transactions/info/{id} endpoints for Lease Cancel transaction, the lease structure now contains lease parameters instead of Lease transaction fields.
  • /leasing/active/{address} returns an array of structures containing lease parameters instead of array of Lease transactions.
  Format

  "lease":
     {
       "leaseId": "4AZU8XPATw3QTX3BLyyc1iAZeftSxs7MUcZaXgprnzjk",
       "originTransactionId": "4AZU8XPATw3QTX3BLyyc1iAZeftSxs7MUcZaXgprnzjk",

     }

Semantic Changes

• For Invoke Script transaction version 3 the fields extraFeePerStep and continuationtransactionIds and the script_execution_in_progress value for the applicationStatus field added to the output of the endpoints providing transaction info.

• dApp-to-dApp invocation results are added as the invokes array to the stateChanges structure returned by the following endpoints:

  • /transactions/info/{id}
  • /transactions/address/{address}/limit/{limit}

  Each element of invokes array, in turn, also contains stateChanges.
