# Blockchain Updates Extension
Blockchain Updates is a node extension that sends blockchain updates via gRPC (opens new window).
This article is intended for Blockchain Updates version 1.2.20 or higher.
Blockchain Updates enables tracking changes made by each transaction and block:
- balance updates,
- leased or unleased WAVES,
- account data storage updates,
- token issues and token parameter updates (including reissue/burning, sponsorship setup, replacing script).
You can obtain updates over a specified range of height or in real time.
Examples of usage:
- Integration with the messenger to send notifications about events on your account.
- Tracking payments to dApp in Invoke Script transactions.
- Calculation of the average weekly account balance (used in the market maker program (opens new window)).
- Services for searching tokens by parameters, searching through account data storages, etc.
# Hardware Requirements
For a node with the Blockchain Updates extension, we recommended to increase the disk space by 50 GB (for instance, at height 2422450, 35 GB is used for extension data).
# Launch Node with Extension
â ď¸ Important: Blockchain Updates requires the history of changes since the blockchain creation. Therefore, you can either start the node with the extension from scratch and synchronize the blockchain during regular node operation (see the Synchronize Waves Blockchain article) or import the blockchain from a binary file (see the Import/Export Blockchain article). This can take 1â3 days. Downloading the latest blockchain database is not applicable.
There are two ways to install the node with Blockchain Updates extension: using a DEB package or a JAR file. The Blockchain Updates extension is in the same package and archive as gRPC Server. You can install these extensions both together and separately, only the settings in the node configuration file differ.
# Installation via DEB Package
Download the latest versions of DEB packages of node and extension from the Releases (opens new window) page (Assets section) on Github.
The extension package name is as follows:
⢠for Mainnet:
grpc-server_{version number}_all.deb⢠for Testnet:
grpc-server-testnet_{version number}_all.deb⢠for Stagenet:
grpc-server-stagenet_{version number}_all.debInstall the packages.
Mainnet:
sudo dpkg -i waves_{version number}_all.deb sudo dpkg -i grpc-server_{version number}_all.debTestnet:
sudo dpkg -i waves-testnet_{version number}_all.deb sudo dpkg -i grpc-server-testnet_{version number}_all.debStagenet:
sudo dpkg -i waves-stagenet_{version number}_all.deb sudo dpkg -i grpc-server-stagenet_{version number}_all.debEdit the node configuration file as described in the Node Configuration article. For Mainnet, the configuration file is located at
/etc/waves/waves.conf, for Testnet at/etc/waves-testnet/waves.conf, for Stagenet at/etc/waves-stagenet/waves.conf.3.1. Add Blockchain Updates to the
waves.extensionssection:waves { ... extensions = [ com.wavesplatform.events.BlockchainUpdates ] }3.2. If you want to change the port for client connection (default is 6881), add the following setting:
waves { ... blockchain-updates { grpc-port = 6888 # Specify port }Start the node.
Mainnet:
sudo systemctl start wavesTestnet:
sudo systemctl start waves-testnetStagenet:
sudo systemctl start waves-stagenet
If the extension runs, it writes messages to the node log:
BlockchainUpdates extension starting with settings <...>
BlockchainUpdates startup check successful at height <...>
BlockchainUpdates extension started gRPC API on port <...>
# Installation via JAR File
Download the latest versions of node JAR file and extension TGZ archive from the Releases (opens new window) page (Assets section) on Github.
TGZ archive name is as follows:
⢠for Mainnet:
grpc-server-{version number}.tgz⢠for Testnet:
grpc-server-testnet-{version number}.tgz⢠for Stagenet:
grpc-server-stagenet-{version number}.tgzUnpack the TGZ archive to the directory containing node's JAR file.
Create a new configuration file or open the existing one, see the Node Configuration article.
3.1. Add Blockchain Updates to the
waves.extensionssection:waves { ... extensions = [ com.wavesplatform.events.BlockchainUpdates ] }3.2. If you want to change the port for client connection (default is 6881), add the following setting:
waves { ... blockchain-updates { grpc-port = 6888 # Specify port }Run the command:
Mainnet
java -cp 'waves-all-{version number}.jar:grpc-server-{version number}/lib/*' com.wavesplatform.Application {configuration file name}.confTestnet:
java -cp 'waves-all-{version number}.jar:grpc-server-testnet-{version number}/lib/*' com.wavesplatform.Application {configuration file name}.confStagenet:
java -cp 'waves-all-{version number}.jar:grpc-server-stagenet-{version number}/lib/*' com.wavesplatform.Application {configuration file name}.confOn Windows, use
;instead of:, for example:java -cp 'waves-all-{version number}.jar;grpc-server-{version number}/lib/*' com.wavesplatform.Application {configuration file name}.conf
If the extension runs, it writes messages to the node log:
BlockchainUpdates extension starting with settings <...>
BlockchainUpdates startup check successful at height <...>
BlockchainUpdates extension started gRPC API on port <...>
# Client Generation
Clone the repository containing protobuf schemes:
git clone https://github.com/wavesplatform/protobuf-schemas/
Generate your client code from the blockchain_updates.proto (opens new window) scheme. Use the gRPC tools for your programming language, find the instructions on the Supported languages and platforms (opens new window) page of gRPC documentation.
# Usage
API Blockchain Updates provides the following functions:
GetBlockUpdatereturns updates performed by the block at the given height.- GetBlockUpdatesRange returns updates performed by the blocks at the given range of height.
- Subscribe returns stream of messages, first historical data (i.e. updates up to the current blockchain height), then current events in real time. Optionally, you can specify the start and/or end height.
See the format of requests and responses in the blockchain_updates.proto (opens new window) file.
# Subscribe
The Subscribe function returns all the events in real time: block append, microblock append, block rollback, microblock rollback (see the Waves-NG protocol description).
If the connection was interrupted, roll back the last block on the client and restart receiving events from the previous block.
Parameters:
| Name | Type | Description |
|---|---|---|
| from_height | int32 | Start height. Optional, 1 by default |
| to_height | int32 | End height. Optional, by default the height is not limited |
The function returns a stream of SubscribeEvent messages.
Message fields:
| Name | Type | Description |
|---|---|---|
| update.id | bytes | ID of the last block or microblock on the blockchain after the event |
| update.height | int32 | Height |
| update.update | Append or Rollback | Event: append or rollback of a block or a microblock. See Event Format below |
| referenced_assets | repeated StateUpdate.AssetInfo | Assets involved in the event. See AssetInfo below |
# GetBlockUpdatesRange
The GetBlockUpdatesRange function returns only historical data of blocks that are already applied. Use it for analytical tasks, where real-time events are not needed, for example, it is enough to update the data once an hour or once a day. We recommend to indicate the end height of the range a few blocks less than the current blockchain height to avoid issues with rollbacks.
Parameters:
| Name | Type | Description |
|---|---|---|
| from_height | int32 | Start height. Required |
| to_height | int32 | End height. Required |
The function returns an array of SubscribeEvent messages. The message format is the same as for the Subscribe function, but contains only messages of a block append.
# Event Format
See the event format in the events.proto (opens new window) file.
Some updates on the blockchain are not associated with any transaction, they are performed at the block level. For example, updates of the block generator balance: 40% of transaction fee that the generator of the current block receives is related to the transaction, and the 60% that the generator of the next block receives is related to the block. The block reward is also related to the block only.
If the transaction fee is indicated in the sponsored asset, then Blockchain Updates returns, in addition to the sender's balance and block generator's balance updates, the sponsor's balance update: the sponsor receives the fee in the sponsored asset and pays the fee equivalent in WAVES. More about sponsorship
# Block Append
When receiving events in real time, the message of a block append can contain transactions and state updates generated by them (if a key block + a microblock are created) or there can be no transactions (if only a key block is created).
Message fields:
| Name | Type | Description |
|---|---|---|
| block | Block (opens new window) | Block data: headers and transactions. See also the Block Binary Format article |
| updated_waves_amount | int64 | Total number of WAVES including the block reward |
| transaction_ids | repeated bytes | IDs of block's transactions |
| transactions_metadata | repeated TransactionMetadata | Additional info about transactions. See TransactionMetadata below |
| state_update | StateUpdate | Blockchain state updates related to a block. See StateUpdate below |
| transaction_state_updates | repeated StateUpdate | Blockchain state updates related to transactions. See StateUpdate below |
transaction_ids, transactions_metadata, transaction_state_updates are parallel arrays: the same index corresponds to the data related to the same transaction. If there is no additional info, then the transactions_metadata array contains an empty value by this index.

# Microblock Append
The message of a microblock append contains only transactions and state updates generated by them that are missed in the previous block/microblock.
Message fields:
| Name | Type | Description |
|---|---|---|
| micro_block | SignedMicroBlock (opens new window) | Microblock data |
| updated_transactions_root | int64 | Transactions Root Hash of all transactions of the current block |
| transaction_ids | repeated bytes | IDs of microblock's transactions |
| transactions_metadata | repeated TransactionMetadata | Additional info about transactions. See TransactionMetadata below |
| state_update | StateUpdate | Blockchain state updates related to a block. See StateUpdate below |
| transaction_state_updates | repeated StateUpdate | Blockchain state updates related to transactions. See StateUpdate below |
transaction_ids, transactions_metadata, transaction_state_updates are parallel arrays: the same index corresponds to the data related to the same transaction. If there is no additional info, then the transactions_metadata array contains an empty value by this index.
