Cardano SL 3.0.0

Overview

Cardano SL 3.0.0 (of Cardano 1.5.0 release) provides a new consensus protocol, Ouroboros BFT, that is important in preparation for moving to the Shelley phase. Ouroboros BFT is a key step in the transition from Ouroboros Classic, the current consensus protocol running the Cardano network in Byron era, to Ouroboros Genesis, the protocol for the Shelley era. (Ouroboros Genesis will be a major upgrade to the protocol that underpins Cardano because it is the first proof-of-stake protocol that matches the security guarantees of proof-of-work protocols such as Bitcoin.)

Ouroboros BFT will not be immediately activated after deployment of the release. It will be activated through a protocol update later, which will be announced separately. This protocol update will deactivate the Ouroboros Classic protocol and activate the Ouroboros BFT consensus protocol. This update will be, technically. a hard fork; it will take place in a smooth and automatic way as a planned protocol upgrade whereby all parties of the current federated system will have agreed to the change.

The v0 wallet API, which was deprecated in Cardano SL 2.0.0 (of Cardano 1.4.0 release), is now completely removed in Cardano SL 3.0.0 and can no longer be used. Therefore cryptocurrency exchanges need to migrate from v0 to v1 wallet API before upgrading to this release.

This release also includes many other improvements like performance improvements when rendering lists with a large number of transactions and wallet addresses, the addition of features for detecting insufficient disk space, and a new screen that visualizes the block storage consolidation process.

Cardano SL 2.0.1

Cardano SL 2.0.1

Fixes

• Relocate fee sanity check and make it relative to each transaction (rather than absolute)
• Correction to block retrieval concurrency and exception handling, so that it will recover in case of certain network failure conditions.

Cardano SL 2.0.0

Cardano SL 2.0.0

Features

• Reduce number of files on disk

  Blund files (containing blocks and their undos) for older epochs (from zero up to current
  epoch minus two) are now consolidated into epoch/index file pairs. That means that the number
  of files to store the block chain for a single epoch is reduced from 21600 (one blund file for
  each slot in an epoch) to an epoch/index file pair. Consolidation happens on-the-fly in a
  background process.

• Add bouncing and throttling to the API

  Previously, exchanges could accidentally overload their wallet servers. We
  have added configurable throttling to the API service to prevent this
  problem. To configure this, setting, view the changes in the
  configuration.yaml file under the wallet section. The API will now return
  a 429 error containing the microseconds to wait until retry. (CBR-179, #3431)

• We can force an NTP-check when getting node-info via the API (?force_ntp_check query flag)

  • CO-325, #3372, #3461, #3607
  • CBR-427 #3586

• The API provides an endpoint to retrieve basic statistics on the UTxO distribution of a wallet (/api/v1/wallets/{walletId}/statistics) (CO-347, #3402)

  • CO-388, #3610
  • CO-389, #3620, #3658

• cardano-sl exposes a new package x509 with tooling for defining a PKI infrastructure from pure Haskell. This is basically an export of the internals of the tool cardano-sl-x509-generate

  Add exception handling code in reporting exception handler, to prevent IOExceptions from killing
  the main thread. This was noticed when the network connection was interrupted, and the reporter
  died when it tried to report over the down network. ([CDEC-470](https://...

Cardano SL 1.3.2

Cardano SL 1.3.2

Fixes

Override max block size for epoch boundary blocks (also called genesis blocks) to have a limit of 1.953 MB rather than incorrectly tracking the max block size configuration persisted on the blockchain.
