An extensible open-source framework for creating private/permissioned blockchain applications
ApiManagerConfig was made non-exhaustive. (#1834)ctrl + c break (on Windows).
These signal handlers may be switched off by using NodeBuilder::disable_signals().
(#1834)run-dev command. Previously, using the existing configuration
files in blockchain-path led to an error. (#1827)create_patch and commit methods in BlockchainMut have been generalized
to support block skipping (see New Features section for more details). (#1820)run-dev command has been reworked. It now does not clear database files
after the launch. artifacts-dir parameter has been renamed to
blockchain-path. Configuration files are now stored inside config
subdirectory. (#1822)MigrationRequest was made non-exhaustive. (#1823)
POST endpoints now expect JSON-encoded input rather than
hex-encoded Protobuf. (#1823)
supervisor_name method was removed. Use Supervisor::NAME instead. (#1823)
command module became public. (#1821)Exonum nodes can now customize how they create block proposals. This can be
used to whitelist / blacklist transaction authors or services, prioritize
transactions by advanced criteria, implement complex rate limiting, etc.
The functionality is available via proposer module. (#1820)
Exonum nodes can now skip block generation at a certain epoch of the consensus algorithm. This can be used to keep a "heartbeat" when the network load is low without bloating the storage used by the nodes. (#1820)
ServiceApiScope::pb_endpoint_mut allows to accept Protobuf-encoded messages
with the request content type set to application/octet-stream in addition
to JSON-encoded messages. (#1829)DeployRequest and MigrationRequest now have cryptographic seeds
to retry the same request multiple times. (#1823)Error handling is now performed with the anyhow crate instead of failure.
(#1805)
APIs which previously used futures from the futures 0.1 crate are now
made async, or are using Futures from the standard library. (#1796, #1804)
The main affected APIs are as follows:
exonum-api crate and their counterparts
in exonum-rust-runtime
ApiSender from the exonum crateNode::run (exonum-node crate) and NodeBuilder::run
(exonum-cli crate), and shutdown with ShutdownHandle (exonum-node crate)TestKitApi (exonum-testkit crate)Testkit now does not include incorrect transactions into blocks or memory pool, similar to real Exonum nodes. (#1785)
Runtime::deploy_artifact no longer returns Box<dyn Future<...>>. Instead a
special communication channel is used to send deployment status from the
runtime to the dispatcher. (#1788)
Schema::call_errors was removed in favor of more comprehensive
call_records method. (#1792)
Blockchain::create_patch and Blockchain::commit signatures were changed
due to unsoundness of the previous implementation; see "Bug Fixes" section
for more details. (#1809)
Replaced CoreError::ServiceNotStopped with the more general InvalidServiceTransition
error. (#1806)
NodeBuilder was refactored to use a more intuitive set of interfaces
for adding built-in artifacts and services to the blockchain. (#1800)command module were made private; the relevant data types
are now exported from the command module directly. Similarly,
io module was made private. (#1799)impl_binary_value_for_pb_message macro was removed. Use the BinaryValue
derive macro from the exonum-derive crate instead. (#1805)Public api module has been removed. List of endpoints from private api has been changed. (#1790) Current list of the endpoints:
v1/info - obtains information about the node;v1/stats - obtains statistics of the node;v1/peers - adds a peer to the Exonum node;v1/consensus_status - enables or disables consensus on the node;v1/shutdown - shuts down the node.API data types were made non-exhaustive where appropriate. (#1799)
TestKitBuilder was refactored to use a more intuitive set of interfaces
for adding built-in artifacts and services to the blockchain. (#1800)
Data types were made non-exhaustive where appropriate. (#1799)
Exonum now supports service freezing. A frozen service has fixed state (i.e., does not process transactions and service hooks), but, unlike stopped services, the service HTTP API remains active. (#1780)
Core and the explorer service now support retrieving call status with a cryptographic proof of authenticity. (#1792)
Exonum now supports unloading of unused service artifacts. This operation may be used to free resources associated with artifacts in the runtime hosting them. (#1794)
Supervisor service supports service freezing. (#1781)
supervisor/services endpoint has been added which obtains information
about deployed artifacts and available services. (#1790)
Supervisor service supports artifact unloading. (#1798)
Rust services support freezing. (#1780)
HTTP API of Rust services is now switched on during data migrations. (#1780)
Fixed potential node hang-up if the node received a proposal and a supermajority of transactions approving it before all transactions in the proposal are known. (#1781)
Switched off broadcasting of transactions which the node considers incorrect. (#1781)
Fixed incorrect invalidation of block proposals. (#1782)
Provided clear coherence period for the transaction pool
by introducing the mempool.flush_config_strategy configuration parameter.
Previously, transactions were flushed to the persistent pool
only on block commit. This led to the unexpected behavior of some APIs,
such as the transaction getter endpoint in the explorer service. (#1809)
Fixed race condition when two nodes try to establish outgoing connections to each other at the same time. (#1804)
Testkit now does not include incorrect transactions into blocks or memory pool, similar to real Exonum nodes. (#1785)
Added a method to get reference to the underlying API client for the TestKitApi.
(#1811)
This release marks the significant milestone in Exonum evolution – the minimum viable lifecycle for Exonum services. Besides dynamic deployment of services implemented in 0.13.0-rc.2 release, Exonum now supports stopping and upgrading service instances (including the possibility of data migrations). Like other lifecycle events, stopping and upgrades are implemented by the core and controlled by the supervisor service, providing flexibility and upgradeability of the control logic.
As a part of service upgrade workflow, Exonum now supports background (aka asynchronous) data migrations. This allows to migrate data from one schema to the other without stopping a node or the blockchain network; the whole process is performed in the background while the node continues processing transactions and other requests. Relevant migration support was added to the storage backend (MerkleDB) and can be used independently.
Other significant changes:
stubs module in the Rust runtime crate for a literary code explainer.See more detailed list of changes in CHANGELOG.md.
No changes to the core functionality are expected between this release candidate and the 1.0.0 release. At the same time, there may be breaking changes to the APIs documented as unstable (for example, data migration). Another kind of potential breaking changes is related to updating core dependencies. Right now, Exonum core targets compatibility with Rust 1.36 due to the problems of compiling the Java runtime with the more recent versions. If this restriction is lifted, some core dependencies will be updated, which could result in breaking changes (at least technically).
Most important: new Dynamic Services feature was introduced. For details see the Dynamic Services section of the changelog.
Used rust version is updated to 1.38.0. (#1481)
create_checkpoint method has been implemented for the RocksDB struct.
This method uses RocksDB checkpoints functionality under the hood.
NotFound error message for explorer/v1/block endpoint now includes
the actual blockchain height. (#1498)
system/v1/rebroadcast endpoint has been removed. (#1445)
Added a possibility to specify compression algorithm for the database. (#1447)
Updated hex dependency with changes in the methods signatures of the ToHex
trait. (#1468)
Validator keys are now derived from single master key. Master key is stored in encrypted file. (#1459)
Command line parameters --service-key-pass and --consensus-key-pass was
removed in favor of --master-key-pass parameter. For example now you can
run the node with the command below. (#1459)
cargo run -- run -d 0/db/ -c 0/node.toml --master-key-pass pass:123
StoppedTestKit::resume accepts list of runtimes instead of a list of services.
Removed obsolete TestKit::blockchain_mut method and TestKit::blockchain
now returns value instead of reference.
Dot symbol is not allowed in service names anymore. (#1558)
Services can now use BlockchainData and SnapshotExt types to access data
from the blockchain in a more structured manner. (#1523)
GenesisConfig is extracted into separate entity. BlockchainBuilder, Node
and Testkit explicitly accepts it during creation. (#1541)
Added DefaultInstance trait for declaration of builtin services. (#1541)
Nested proofs for ProofListIndex are replaced with a flat
(non-recursive) format. (#1450)
Differentiated (read-only / read-write) access to the database was introduced. (#1523)
It is now possible to have readonly access to indexes given a Fork
via a ReadonlyFork wrapper. Readonly access works like RefCell::borrow
(vs RefCell::borrow_mut for Fork); it is possible to create an
unlimited number of indexes with readonly access based on the same fork.
(#1523)
Service schemas can now use a declarative layout, in which every field
corresponds to a separate index or a group of indexes. It is possible
to derive a constructor for such schemas via FromAccess derive macro.
(#1523, #1562)
New index name restrictions has been added. (#1558)
Dot symbol is not allowed anymore in indexes with prefixed access.
Index names starting from __ and not containing a dot . are reserved and
used only for system indexes.
exonum-proto. Trait ProtobufConvert is moved
to this crate. (#1496)Introduced a new crate exonum-protobuf-convert. Derive macro
ProtobufConvert is moved to this crate. (#1501)
Derive macro ProtobufConvert now does not derive the BinaryValue and
ObjectHash traits. There are separate derive macros for them in
the exonum-derive crate. (#1501)
Method protobuf_generate is now private, use exonum_build::ProtobufGenerator
instead (#1496).
Method ProtobufGenerator::frequently_used has been removed (#1581).
Methods read_keys_from_file and generate_keys are moved to new keys
module in the exonum. (#1459)
Protobuf serialization for crypto types is now implemented in the exonum-crypto
crate. (#1496)
In exonum 0.13.0-rc.2, a new service workflow is introduced, named
"Dynamic Services".
Key points of this feature are the following:
exonum now supports different environments of code execution (runtimes).
Only native rust runtime is enabled by default, but support of
different programming languages can be added quite easily.
For details see the Runtime trait docs and the
sample_runtime example.
Services are not statically tied to the compiled binary anymore. There is support of adding new service types (aka artifacts) dynamically and starting new instances of services.
For details see runtime module docs.
Services now can have initialization parameters, provided within service start procedure.
Services now support configuration changes via Configure interface.
configuration service was replaced with the supervisor service, which is
capable of not only changing configuration, but of deploying and starting
services as well. For details see supervisor service.
There are a lot of backward-incompatible changes introduced within 0.13.0-rc.2 release candidate.
So to make the changes apparent, compare the Cryptocurrency example service versions
for 0.12.1 and 0.13.0 releases.
Key points:
Merkledb schema is now declarative and can contain indices as fields.
Access to the database is now isolated for services. A service cannot get the write access to another service or the blockchain schema.
Transactions do not have the execute method anymore. Instead, a service defines
and implements an interface trait which contains all the business logic.
Services do not launch at the node start by default. For launching a
service, use an exonum-launcher tool.

New config params http_backend_config.server_restart_max_retries and
http_backend_config.server_restart_retry_timeout added into NetworkConfiguration.
They are intended to configure restart settings of the HTTP-server (#1536).
exonum now has a python library for implementing integration tests. (#1516)
BlockchainMut now has a check_tx method used to verify transactions before
adding them to the transactions pool. Transactions for which check_tx fails
are considered invalid and can't be included to the block. (#1579)
ProofListIndex now implements truncate() and pop() methods, allowing
to eject elements from the list. (#1455)
IndexAccess trait is implemented for several new types, notably,
Rc<dyn Snapshot>, Arc<dyn Snapshot> and Rc<Fork>. (#1455)
HashTag::hash_list() was extended to support values of any appropriate type,
not only Hash. (#1455)
ProtobufConvert has been implemented for MapProof (#1512) and ListProof (#1513).
New variant of the ProofMapIndex have been introduced - RawProofMapIndex.
It is used for keys that maps directly to ProofPath, for example Hash and
PublicKey. (#1531)
By default ProofMapIndex is used for keys that implement ObjectHash.
For Hash keys both map variants works the same, because ObjectHash
implementation for Hash returns the hash itself.
Old fabric module is replaced with new exonum-cli crate. (#1443)
exonum-cli provides a public reexport of structopt crate. (#1461)
system/v1/shutdown endpoint has been modified and now accepts empty POST
requests. (#1526)
exonum-protobuf-convert has been replaced with external protobuf-convert
crate. (#1561)
keys module has been moved into exonum-keys crate. (#1497)
ProofListIndex::extend() method has been refactored, leading to up to 10x
performance improvements for large lists. (#1455)
Proofs building mechanisms have been heavily refactored. (#1460)
exonum-supervisor crate. (#1582)run-dev mode. (#1415)index_metadata now correctly loads the provided index address name (#1478).Signatures of methods Service::initialize and Service::before_commit has been
changed. Now they take immutable reference to Fork instead of mutable. (#1293)
Trait BinaryForm has been replaced by BinaryValue. (#1298)
To implement BinaryValue for types that implements Protobuf::Message use
impl_binary_value_for_pb_message macros.
Module storage has been replaced by exonum-merkledb crate. See related section
in changelog for details. (#1293)
Bootstrapping workflow has been simplified (#1292)
generate-config subcommand now uses single OUTPUT_DIR instead of set of options.
So to generate node config you should write something like example bellow.
cargo run --bin exonum-timestamping -- \
generate-template /tmp/exonum/template.toml --validators-count 4
cargo run --bin exonum-timestamping -- \
generate-config /tmp/exonum/template.toml /tmp/exonum/cfg/0 \

cargo run --bin exonum-timestamping -- \
run -d /tmp/exonum/db/0 -c /tmp/exonum/nodes/0/node.toml
explorer/v1/blocks endpoint with add_blocks_time param switched on now returns
median precommit times in the time field within each returned block,
rather than in a separate array. (#1278)
system/v1/mempool endpoint has been renamed into system/v1/stats.
An additional field in the response of the endpoint was added. The field
corresponds to the total number of transactions in the blockchain. (#1289)
Added restrictions to index names. Allowable characters in index name: ASCII characters, digits, underscores and dashes. (#1388)
Added Debug implementation for Database, Snapshot, Iterator dynamic
traits (#1363)
Changed storage layout (#1293)
Changed indexes metadata layout in the database.
Introduced a generic IndexState structure that can be used to store global
index properties like total number of items.
Changed ProofMapIndex hashing rules for branch nodes and root node.
Branch nodes is hashing now with 0x04 prefix, root node with 0x03 (#1293).
Renamed method merkle_root of ProofMapIndex and ProofListIndex to
object_hash (#1293).
Several mutable indexes now can be create from immutable reference to Fork (#1293)
Relaxed trait bounds for the ProofMapIndex keys (#1293)
Now keys should just implement BinaryKey trait instead of the
ProofMapKey, which will be ordered according to their binary
representation, as in the MapIndex.
Changed ProofListIndex hashing rules for leaf nodes and branch nodes according
to the certificate transparency
specification. Leaf nodes contain hashes with 0x00 prefix, branch nodes - with
0x01. (#1293)
StorageValue and StorageKey have been renamed to the BinaryValue
and BinaryKey. (#1293)
to_bytes method to the BinaryValue trait which doesn't consume
original value instead of the into_bytes.BinaryKey::write now returns total number of written bytes.CryptoHash has been replaced by the ObjectHash.Changed the hash algorithm of the intermediate nodes in ProofMapIndex. (#1293)
ProofPath now uses compact binary representation in the BranchNode
hash calculation.
Binary representation is |bits_len|bytes|, where:
ProofPath in bits compressed
by the leb128 algorithmProofPath, i.e. the first
(bits_len + 7) / 8 bytes.New endpoint: v1/transactions/subscribe, which subscribe to new transaction events.
This endpoint accept optional parameters: service_id and message_id
(message_id as in derive macro TransactionSet). (#1335)
New endpoint: v1/ws, which open websocket connection and allow to set multiple
subscription (for blocks and transaction, filtered by service and transaction id)
and send transactions (in hex, like in explorer) to blockchain
(examples can be found in related pull request). (#1335)
TestKit::add_tx() method, which previously did not persist
transactions. (#1278)explorer/v1/blocks endpoint supports add_precommits param, which supplies
each returned block with the precommits field. (#1278)
explorer/v1/blocks endpoint allows to specify the lower bound on the returned
block height with the earliest query param. (#1278)
Added ProtobufConvert implementation for byte array with fixed sizes (#1279)
Added service_name getter to the TransactionContext. (#1274)
Allowed to use symbol - in index names. (#1277)
rocksdb crate is now used instead of exonum_rocksdb. (#1286)
Added a new endpoint system/v1/services for displaying information
about available services. (#1288)
Endpoints explorer/v1/block and explorer/v1/transactions were extended
with adding additional fields service_id and time. (#1386)
Added tx_cache field to State to cache incoming transactions before
adding them to persistent pool. (#1398)
Added new request message PoolTransactionsRequest to obtain pool transactions
from another peers. (#1404)
Updated ProofMapIndex data layout. (#1293)
Path to the root node in merkle patricia tree now has been stored in the index state.
New API for getting and creating indexes. (#1293)
Now indexes can be accessed via immutable references from Snapshot and
mutable/immutable references from Fork.
Introduced method fork::get_object to get or create object by address.
get_object_existed and get_object_existed_mut methods of Fork and Snapshot
returns optional references to index.
rocksdb crate is now used instead of exonum_rocksdb. (#1286)
Added From<Patch> trait implementation to Fork. (#1403)
TestKit, allowing to emulate node
restarts. (#1278)Node secret keys are now stored in separate files in a secure way. CLI for generating node configs and starting nodes has been extended in order to reflect these changes. (#1222, #1096, #1235)
Changed a response for /healthcheck endpoint. (#1252)
Changed a response code for the /block endpoint for the case when
the requested block doesn't exist. (#1262)
Removed a sub-command generate-testnet from CLI. (#1264)
create_keys_file function to generate_keys_file
in utils module. (#1222, #1096)Added allow-origin for localhost for public and private api in
development mode by default. (#1234)
Added ProtobufConvert implementation for Signature. (#1241)
