Photon (v0.4.0)

MainNet Preview (codename: Photon)

Photon (v0.4.0) is our last pre-release. IoTeX blockchain is almost feature complete. In this release, we added multi-chain feature, enhanced consensus, and improved overall performance and robustness. The full list of new features are as follows:

1. TBC (Transactions, Block & Chain)

• Sub-chain provisioning protocol
• Deposit to sub-chain
• Commit state root to the block header
• State storage pruning
• Gas fee collection

2. Consensus

• Performance improvement: consensus latency 10s -> 7s
• Security improvement: authenticating proposer and validators
• Time slot based proposer rotation
• Preliminary implementation of distributed key generation protocol

3. Testing & Deployment

• Scaling deployment to 101 nodes
• Load test of 1K+ TPS at peak
• Option to spin-off index data into separate RDBMS

4. Engineering excellence

• Action abstraction
• Action handling framework (native “smart contract” in golang)
• State working set to isolate uncommitted state change

5. Documentation

• Protocol (data schema, wire format, and so on)

Epik^2 (v0.3.2)

iotex-core v0.3.2 is a patch release that contains the following bug fixes:

• Validate recipient address in actpool and blockvalidator
• Let nodes panic if committing state changes fails & Add some error logs in statefactory
