Version 1.6.2 Champagne (Mainnet + Testnet + Stagenet)

In this release

This release brings Deterministic Finality feature and P-256 EC signature verification to Mainnet. The node now requires Java 17 to run. For more information, see the Release Notes.

Activation

Please vote for feature #​25 on Mainnet! The current voting window started at height 5180000. If the features are voted during this voting interval, activation will happen at height 5200000 (2026-04-28 03:16 UTC). Feature #25 has been activated on Testnet.

Refer to the instructions on how to commit to block generation.

Update notes

This release requires Java 17 (or later) to run.

Testnet Rollback

Due to incompatibilities with version 1.6.1, Testnet has been rolled back to block 4047001. Testnet data snapshot is available form blockchain-testnet.wavesnodes.com. To ensure your node is on the correct chain after getting the state snapshot, check block ID at height 4047002, it should be 4ZaqURxBkV3vDxLkLjz86VeTG34PK1rB8UUeRKUf8BNu on the new chain.

There's no need to rebuild the state when updating from 1.5.12.

Version 1.6.1 (Testnet + Stagenet)

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

Please note that DEB packages attached to this release have been re-uploaded on 2026-02-18.

In this release

This release improves the Deterministic Finality feature, as well as enables P-256 signature verification in RIDE.

fromBase64String_1C	Max resulting byte array size is 1024 bytes.	1

P-256 EC Signature Verification

The following new functions have been added to support Intel TDX:

• p256Verify(message: ByteVector, signature: ByteVector, publicKey: ByteVector): Boolean, complexity: 43.
  This function takes raw message bytes (unhashed), raw signature bytes and raw public key bytes and verifies P-256 signature. This function uses SHA-256 to hash the message. Both signature and public key must be exactly 64 bytes.
• validateCertificateChain(certificates: List[ByteVector], crls: List[ByteVector], timestamp: Int): ByteVector, complexity: 43.
  This function takes a list of DER-encoded X.509 certificates (the first one being the most specific, and the last one being the root certificate), a list of corresponding CRLs, and a timestamp, and performs certificate chain validation. All CRLs and certificates must be valid at the given timestamp. If the certificate chain is valid, this function returns the public key (raw 64 bytes) of the first certificate (the most specific one) and throws an error otherwise. Only valid EC public keys are supported.

Native Crypto Providers

This release includes two native crypto providers: Amazon Corretto and Conscrypt. These providers significantly improve P-256 verification performance, as well as SHA-256 hashing performance. Both providers have comparable performance. However, due to the way Amazon Corretto is distributed, when node is started from a fat jar under Linux running on ARM, Java based Bouncy Castle provider will be used. This provider has significantly lower performance. For now it's recommended to use Docker images on Linux on ARM instead of a fat jar.

Update notes

There's no need to rebuild the state when updating from 1.6.0 or 1.5.12.

Version 1.6.0 (Stagenet)

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

In this release

This release introduces the new Deterministic Finality feature that will help achieve 2-block finality under most circumstances.

Protocol enhancements

Deterministic Finality

Once feature 25 is activated, miners will need to commit to generation in the following Generation Period by sending a CommitToGeneration transaction. Generation Period duration varies by network (1000 blocks for Stagenet, 3000 blocks for Testnet, and 10000 blocks for Mainnet). Besides mining new blocks, upon successful block application, the node will automatically broadcast the signed endorsement of the parent of the newly applied block to its peers. The miner of the current block collects the endorsements from its peers and includes them in the current block. Since only committed generators can participate in block production, for each Generation Period the total generating balance is known. The block endorsed by at least 2/3 of the total generating balance is considered finalized: the node will not rollback beyond that block when switching to another chain.

If no miners have committed to the next Generation Period, or neither of the committed generators have enough generating balance (at least 1000 waves), the blockchain falls back to the previous miner selection mechanism where anyone with enough balance can forge new blocks. In this case the block at (current height - 100) will automatically finalize.

CommitToGeneration Transaction

Besides the standard transaction fields, this transaction contains:

1. the BLS public key derived from the private key the node will use to sign block endorsements
2. the start height of the next Generation Period
3. BLS signature of the concatenated (1) and (2)
   To commit to generation, the miner must provide the deposit of 100 waves. This deposit is locked from the moment of the transaction processing up until the end of the Generation Period the miner is committing to. This deposit is withheld if the miner broadcasts conflicting endorsements.

You can sign a CommitToGeneration transaction with one of the keys in the node's wallet by using the /transactions/sign API endpoint. By default, the node will find the key pair corresponding to the address in the sender field of the request JSON, use the private key as the BLS public key, create the BLS signature and sign the transaction with the waves private key.

Ride

• Released version 9 of the Standard Library.
• Added CommitToGeneration transaction binding.
• Decreased complexity for several functions.

Node REST API

• /generators/at/{height} lists all generators committed to mining at height and their respective generating balances, as well as heights where they have sent conflicting endorsements, if any.
• /blocks/height/finalized returns the height of the currently finalized block.
• /blocks/finalized and /blocks/headers/finalized returns the current finalized block and its header, respectively.
• /blocks/finalized/at/{height} returns the height of the block that has been finalized at height.
• finalizationVoting in block JSON contains both the indexes of valid endorsement senders and conflicting endorsements collected by the miner of this block.

Version 1.5.8 (Mainnet + Testnet + Stagenet)

In this release

This is an optional release with several bugfixes:

• Improved connectivity: nodes no longer ban each other as aggressively as before, and also share only those peer addresses that they were able to connect to.
• Improved the performance of API methods retrieving balances at specific heights.

Also several new commands were added to the node's CLI:

• gengen can be used to generate custom genesis block
• crypto create-keys has been extended to accept wallet seed

Update notes

Even though this release is optional, we recommend everyone to update their nodes to benefit from connectivity improvements. There's no need to rebuild the state when updating from 1.5.7.
