Hyperchains v1.1.0
Hyperchains
This is an External release-candidate of Hyperchains as described in Periodically Syncing HyperChains.
NOTICE: This is a public release candidate of Hyperchains functionality, intended FOR TESTING PURPOSES ONLY. No assets of value should be committed to Hyperchains until the first stable release. The tools involved in setting up and using Hyperchains are still under development, and you may encounter bugs or error messages.
NOTICE: This release is not compatible with RC3 and previous tests chains cannot be rolled over between release candidates
Developers can find detailed instructions on creating a Hyperchain in the Hyperchains documentation. This resource is best suited for those familiar with aeternity nodes. The tarballs included in this release are intended for expert æternity developers.
Hyperchains unify the efficiency of proof-of-stake (PoS) chains with the trusted security and unique features of the aeternity proof-of-work (PoW) blockchain, with broader PoW chain compatibility forthcoming.
An aeternity Hyperchain comes with all the normal features of aeternity:
- FATE VM: Efficient virtual machine for executing smart contracts.
- Sophia Language: A functional programming language for secure smart contracts.
- State Channels: Off-chain scaling for private and secure transactions.
- AENS: Æternity Naming System for human-readable addresses.
- Oracles: Bridging real-world data into the blockchain ecosystem.

About this release
This preliminary implementation of Hyperchains lays the foundation for a scalable and energy-efficient blockchain system. Key features introduced in this release include:
- Possible to spin up hyperchain on local machine with æternity as pinning chain also running on local machine.
- Introduction of Epochs.
- Introduction of a Staking Cycle.
- Future leader election.
- Leader schedule per epoch.
- Pinning. Instead of posting every block on parent chain, pin at most once per epoch.
- Fix block synchronization.
- Change from Bitcoin.NG to 1 microblock per generation.
- Change the order of keyblock and microblocks.
- Introduce block flags for placeholder for late blocks.
- Introduce a real notion of time.
- Hyperchains configuration including contracts and configurable coinbase and timings.
Core Features
-
Staking Mechanism
- Enables participants to stake tokens and qualify for block production and validation. The staking framework ensures fairness and rewards based on contributions and performance.
-
Periodic Synchronization with Pinning Mechanism
- Introduces a semi-lockstep synchronization model that aligns the epochs of Hyperchains with the pinning chain.
- A cryptographically secure pinning mechanism anchors the hyperchain state to the pinning chain, ensuring robust alignment and reduced operational overhead.
-
Future Leader Election
- Implements a randomized leader election system, utilizing entropy derived from the pinning chain.
- This ensures predictable and secure block production, enhancing efficiency and reducing the need for frequent consensus actions.
-
Finality Guarantees
- Fast Finality: When all validators are online and behaving correctly, blocks achieve instant finality.
-
High Throughput
- Optimized system design supports processing a high volume of transactions, meeting the demands of modern blockchain applications.
Governance and Consensus Enhancements
- Efficient Consensus Mechanism
- Randomized leader election reduces the need for frequent votes, streamlining the consensus process and lowering computational overhead.
Key Improvements Over Previous Releases
- Reduced pinning-Chain Dependency
- Optimized the relationship between the hyperchains and pinning chains, minimizing interaction and operational costs while maintaining security.
Known Limitations
This pre-release does not yet address all advanced features proposed in the whitepaper, such as enhanced fork resolution strategies and multi-epoch staking scenarios.
- Fork resolution is not fully implemented.
- Voting is not fully implemented.
- Fee distribution between block producers is not optimal.
- Default values for token economics are not yet fully balanced.
- Performance is not fully tested and optimized.
Plans for Version 1.0.0
The 1.0 release aims to achieve the following:
- Comprehensive Fork Handling: Implement robust solutions for fork scenarios.
- Enhanced Staking Options: Introduce multi-cycle locking and flexible staking schedules.
- Optimized Block Production: Refine reward distribution to incentivize timely and accurate block creation.
- Enhanced Token Economics: Refine fees, rewards and penalties in default configuration and present configuration suggestion for different scenarios.
- Improved API: Depending on community feedback the hyperchain API might be changed in version 1.0.0
Future Releases
Planned updates will focus on:
- Performance
- Enhanced governance through voting
- More advanced staking and delegated staking mechanisms
- Improve end of Epoch voting and progress
- Clean up Bitcoin.NG legacy.
Feedback and Collaboration
We encourage the aeternity foundation to engage with this release and provide feedback through Æternity’s GitHub repository. Together, we aim to refine Hyperchains into a robust and scalable blockchain solution.

Ceres Release
- Testnet protocol upgrade has been scheduled for block 939750 estimated to Wed Apr 24 08:30:00 UTC 2024.
- Mainnet protocol upgrade has been scheduled for block 941700 estimated to Tue May 7 09:00:00 UTC 2024.
What's Changed
Ceres Protocol Changes
- Only allow GAAttachTx for nonce 1 - i.e. an account cannot later be transformed into a generalized account.
- Adjust the AENS auction mechanism;
- make auctions initially shorter
- new bids only extend auctions with a short period,
and it is only extended if the new bid comes near the end of the auction (within the extension period).
- Make NamePreclaimTx optional. Since the introduction of auctions, the front-running protection offered by the 'PreClaim -> Claim' flow is no longer as important. To simplify name registrations (or the start of a name auction) we now allow NameClaimTx without a previous NamePreclaimTx. In this case we set the
NameSaltto0. - Adds new operations to the FATE VM (version 3)
- bitwise operations on integers (
band,bor,bxor,bnot,<<and>>) - Address.to_bytes - converting an address to its binary representation
- Int.mulmod - a combined multiplication and modulus operation for efficiency
- Crypto.poseidon - a ZK/SNARK friendly hash function
- Introduce arbitrary sized binary arrays (type
bytes()); addingBytes.split_any,Bytes.to_fixed_size,Bytes.to_any_size,Bytes.size,String.to_bytes, andInt.to_bytes; and adjustBytes.concat, andCrypto.verify_sigto allow both fixed and arbitrary sized byte arrays. - Chain.network_id - the network id of the chain
- bitwise operations on integers (
- Change the micro block gas limit to use actual used gas instead of upper gas limit.
This makes the network work better when contract calls are overestimated and allow for more transactions to fit in each block. - Allow contracts to be called by name. The key
contract_pubkeyof the name is resolved while running the transaction.
This has consequences for the contract call structure (aect_call) that gets a new field with the contract call identifier.
In order to be able to find the call result without doing name resolution calls are stored relative to the id rather than the contract pubkey.
NOTE: Names can change at any time (frontrunning is possible!) so only call
contracts by name when you trust the owner of the name! - Introduce a new type of pointer for AENS names. The raw data pointer/value is
an arbitrary sized byte array (max 1024 bytes). And since before there is a
maximum of 32 key-pointer pairs. FATE VM and Sophia are updated to allow full
access to the new pointer type (See
https://github.com/aeternity/aesophia/blob/master/docs/sophia_stdlib.md#aensv2). - Add generic/wildcard AENS delegation signatures. I.e. instead of delegating
authority for a contract to operate with a specific name (name hash), by
signing just the stringAENS(+ network id, public key and contract address
as usual) you can delegate the authority for a contract to handle all your
names with one signature. See Issue #4080 for details.
BEWARE: This gives the contract authority to handle all current and future
names on your behalf, so it should be used with extreme care and only for
well-known (and well understood!!) contracts. - Include fields
feeandgas_pricein GAMetaTx when computing the TX-hash
of the inner transaction. This way a malicious miner can't change them before
inserting the transaction in a micro block. Note: The authentication logic
still needs to actually use the Auth.TxHash during authentication for this
to take effect! - Set Protocol Upgrade heights for CERES by @hanssv in #4333
- More structured delegation signatures by @hanssv in #4219
