April 2023-04-13 (v0.12)

Robustness fixes for event log subscriptions, including ensuring no dropping of event logs, removal of any duplicates, and ensuring correct ordering based on their block insertion.
Event log subscriptions will now infer the correct viewing key to use for relevancy checks performed by an Obscuro node. This is based on filter criteria in the subscription, e.g. when a particular address field is included in the filter list, if a viewing key for that address is registered, that key will be used. Note that subscriptions to all events, where those events might contain data used in the relevancy checks, will not be able to infer the viewing key to use, and as such will use the first registered key made through that instance of the wallet extension.

A variety of stability related issues are fixed within this release.
Inclusion of a health endpoint for system status monitoring.
It is now possible to run an Obscuroscan against a locally deployed testnet. For more information see building and running a local testnet in the project readme.
Obscuroscan’s GitHub Actions deploy script has been modified to run the public Testnet Obscuroscan as an Azure web app. This allows access via HTTPS (TLS), which allows app developers to call the Obscuroscan API from other web apps.

November 2022-11-08 (v0.6)

The Number Guessing Game has been removed from static and auto deployment scripts, and is now hosted in a sample applications repository. Given the move for Testnet to be long-running (or at least restartable without contract disappearance), the Guessing Game must be persisted across software updates, and redeployed manually if needed in the same way other applications are.
The list of sensitive RPC API methods, where the request and response is encrypted in transit, now covers eth_call, eth_estimateGas, eth_getBalance, eth_getLogs, eth_getTransactionByHash, eth_getTransactionCount, eth_getTransactionReceipt and eth_sendRawTransaction. See the Obscuro documentation for more details.
Calls to wait for a transaction receipt are now blocking, whereas previously they would return an error meaning the client side code needed to perform a specific wait and poll loop. The example on how to programmatically deploy a contract has been updated accordingly.
The ability to start a faucet server against a local testnet deployment is now supported via a docker container. For more information see the Obscuro readme.
Updates to the Events design inclusion of the Fast Finality design.
The Obscuro docs site is now searchable.
Testnet is now officially termed Evan's Cat.
ObscuroScan:
- ObscuroScan supports a single API at /rollup/ which allows web clients to access a JSON representation of rollups and encrypted transactions. Further details here

October 2022-10-21 (v0.5)

Event Subscriptions:
- Event subscriptions for logs are now supported via the eth_subscribe and eth_getLogs approaches. This has been tested using both the ethers and web3js libraries. Note that eth_newFilter is not currently supported. For more information see the events design.

September 2022-09-22 (v0.4)

Wallet extension:
- The wallet extension now supports separate ports for HTTP and WebSocket connections. Use the --port and --portWS command line options respectively for each. For more information see the Wallet extension documentation.
Event subscription:
- An early preview of event subscriptions is available in this release, though note that this is still undergoing testing and feature enhancements and therefore is liable to issues and instability. For more information on the functionality available reach out to the development team on the discord active testnet developers channel.
Transaction receipts:
- Only return receipts for transactions which were included in a canonical rollup.

September 2022-09-07 (v0.3)

Tokens / ERC20 contracts
- The ERC20 ‘HOC’ and ‘POC’ tokens are now funded with 18 decimal places of precision. Previously funding of 50 tokens was erroneously made as 50 10^-18. This means tokens imported into Metamask will display correctly. Note that the number guessing game pay to play still costs 1 10^-18 HOC tokens.
Wallet extension:
- Viewing keys are now persisted across wallet extension restarts
- Enhanced logging for registering of viewing keys

August 2022-08-22 (v0.2)

Account balances:
- Added correct calculation of account balances (previously, all accounts were allocated infinite funds).
Tokens / ERC20 contracts
- The two pre-installed ERC20 contracts deployed are now named ‘HOC’ and ‘POC’, replacing the previous tokens of ‘JAM’ and ‘ETH’. Contract addresses remain the same as before respectively. The tokens have restricted balanceOf and allowance calls such that only the owner of the account can view details which should be private to them. See go-obscuro\integration\erc20contract\ObsERC20.sol for more information.
- Testnet now supports a faucet to distribute native OBX on request. Previously pre-funding of accounts meant that no native tokens were required to execute transactions on Obscuro - this is now not the case and native tokens must be requested. Allocation of native OBX, along with HOC and POC tokens is currently not supported automatically and a request to Obscuro Labs should be made on the Faucet Discord channel.
Gas prices:
- The node operator can configure the minimum gas price their aggregator will accept on startup.
Wallet extension
- The wallet extension now supports multiple viewing keys through a single running instance. For more information see the wallet extension design doc, specifically Handling eth_call requests for how the required viewing key is selected when multiple keys are registered.

August 2022

Testnet launch:
- Testnet preview launched to limited number of application developers.
- ObscuroScan block explorer for Testnet launched.
- Number Guessing Game smart contract deployed to Testnet.
Obscuro Docsite launched.
Account balances:
- Added correct calculation of account balances (previously, all accounts were allocated infinite funds).
- Introduced network faucet account.
- Obscuro enclaves services can configure the minimum gas price they’ll accept
block.difficulty will return a true random number generated inside the secure enclave.
