• Improves the java-Tron upgrade mechanism and achieves more efficient decentralized governance (#3314).

GreatVoyage-v4.0.0 Release

Release 4.0 has implemented the shielded TRC-20 contract, which can hide the source address, destination address, and the token amount for TRC-20 transactions and provide users with better privacy. The shielded TRC-20 contract has three core functions: mint, transfer and burn. mint is used to transform the public TRC-20 token to shielded token; transfer is used for shielded token transactions; burn is used to transform the shielded token back to the public TRC-20 token. To support the shielded TRC-20 contract, four new zero-knowledge instructions (verifyMintProof, verifyTransferProof, verifyBurnProof and pedersenHash) are added in TVM, which make it convenient to provide privacy for arbitrary TRC-20 contract.

Forced upgrade

New Features

---

• Add 4 new instructions (verifyMintProof, verifyTransferProof, verifyBurnProof and pedersenHash) in TVM to support TRC20 shielded transactions based on zk-SNARKs (#3172).
  • verifyMintProof: used to validate the zero-knowledge proof for mint function.
  • verifyTransferProof: used to validate the zero-knowledge proof for transfer function.
  • verifyBurnProof: used to validate the zero-knowledge proof for burn function.
  • pedersenHash: used to compute the Pedersen hash.
• Update the initial parameters of zk-SNARKs scheme generated by the MPC Torch (#3210).
• Add the APIs to support shielded TRC-20 contract transaction (#3172).
  • Create shielded contract parameters
    

    rpc CreateShieldedContractParameters (PrivateShieldedTRC20Parameters) returns (ShieldedTRC20Parameters) {}

  • Create shielded contract parameters without ask
    

    rpc CreateShieldedContractParametersWithoutAsk (PrivateShieldedTRC20ParametersWithoutAsk) returns (ShieldedTRC20Parameters) {}

  • Scan shielded TRC20 notes by ivk
    

    rpc ScanShieldedTRC20NotesByIvk (IvkDecryptTRC20Parameters) returns (DecryptNotesTRC20) {}

  • Scan shielded TRC20 notes by ovk
    

    rpc ScanShieldedTRC20NotesByOvk (OvkDecryptTRC20Parameters) returns (DecryptNotesTRC20) {}

  • Check if the shielded TRC20 note is spent
    

    rpc IsShieldedTRC20ContractNoteSpent (NfTRC20Parameters) returns (NullifierResult) {}

  • Get the trigger input for the shielded TRC20 contract
    

    rpc GetTriggerInputForShieldedTRC20Contract (ShieldedTRC20TriggerContractParameters) returns (BytesMessage) {}

• Support the ovk to scan the transparent output of burn transaction (#3203).
• Support the burn transaction with zero or one shielded output (#3224).
• Add data field in transaction log trigger class for future memo note (#3200).

The following TIPs are implemented in this release:

• TIP-135: Shielded TRC-20 contract standards, guarantee the privacy of the shielded transfer of TRC-20 tokens.
• TIP-137 : Implements three zero-knowledge proof instructions in TVM to support the shielded TRC-20 contract (#3172).
• TIP-138 : Implements the Pedersen hash computation instruction in TVM to support the shielded TRC-20 contract (#3172).

• Check if null before getInstance when get transaction info from DB to fix exception of getTransactioninfoByBlkNum (#3165).

Odyssey-v3.7 Release

Notice

---

Non-mandatory upgrade

Changes

---

• (#2533) Several independent modules are separated, including consensus module, crypto module, chainbase module, framework module, protocol module and actuator module, which makes decoupled code easier to be extended and enable developers to implement custom logic freely.
• (#2947) Extend solidity event subscription trigger, user can get the event which is solidified.
• (#2958) Add gettransactioninfobyblocknumAPI including HTTP and GRPC, user can get the list of transaction information by block number.
• (#2352) Add broadcasthex API for HTTP, the user can broadcast the hex of the transaction.

• How to get the list of transaction information in a specific block: TRON Documentation
• How to broadcast the hex of the transaction: TRON Documentation

Odyssey-v3.6.6 Release

Notice

Forced upgrade

Changes

---

• #2766 Fix HTTP API updateBrokerage to support base58 encoding.
• #2813 Extend the allowed instruction sets for off-chain smart contract call, including LOGn, SSTORE,CREATE, CREATE2, STATICCALL, SUICIDE instructions.
• #2824 Remove the functionality “Forbid transfer asset to a smart contract using TransferContract and TransferAssetContract” from proposal 32 and implement it with a new proposal 35.

Odyssey-v3.6.5 Release

Notice

---

Forced upgrade

New Features

---

• tronprotocol/tips#37 #2445 Prohibit using TransferContract & TransferAssetContract to transfer TRX and assets to smart contract account.
• tronprotocol/tips#43 #2422 Add a new TVM instruction that supports parallel signature verification, speeding up the verification process and cutting Energy consumption.
• tronprotocol/tips#44 #2323 Add a new TVM instruction to identify whether the account is a smart contract account or not.
• tronprotocol/tips#53 #2464 Optimize the current TRX staking mechanism and move the dividend distribution to the On-Chain. The default value of the commission rate is set 20%.
• tronprotocol/tips#54 #2439 Automatic activation of accounts when transferring TRX/TRC10 tokens in smart contracts.
• tronprotocol/tips#60 #2471 Add a new TVM instruction that supports multi-signature verification.

Changes

• #2407 Fix the issue of misreporting NullPointer exception on the occasion of triggerConstantContract transaction timeout.
• #2457 Fix the bug that it can not load the localWitnessAccountAddress configured by the "keystore" config item if the SR modified the witness permission.
• #2458 Fix the bug that resources for delegate can not be unfrozen after the contract account suicided and became a normal account.
• #2462 Add triggerConstantContract feature for Solidity Node and FullNode Solidity interface.
• #2463 Add proposals for modifying parameters of energy dynamic adjustment. The way to add up energy consumption is changed from adding up the freeze energy consumption to adding up all the energy consumption.
• #2485 Fix the bug about there is no data for return of some solidity APIs.
