Nervos CKB Development Update #41
Covering Oct 26 to Nov 8, 2020
Extending ckb-indexer
The ckb-indexer allows data to be queried from nodes for applications and analytics.
Quake has been working on ckb-indexer based on the requirements from this talk thread. He considered several solutions and is still optimizing the trade-offs.
Fee Estimator
Accurate fee estimation is important for applications and Layer 2 protocols.
Boyu continues working on the fee estimator. He has implemented a prototype and has been evaluating different models. He also discussed the pool requirements to support the fee estimator with Dingwei.
Metrics Dashboard
Current metrics can be found on the CKB explorer.
We have TPS and chain sync benchmarks, but we haven’t stored the results for analysis. Guozhen and Yulong have been working on the metrics dashboard, which will ease metrics presentation, analysis and comparison.
Traits Design
In Rust, atrait is a collection of methods defined for an unknown type: Self. They can access other methods declared in the same trait.
Dingwei started to re-design the traits in the CKB source code. We used to design fat traits that provided all the functionalities the underlying modules could provide. This bottom-up strategy leads to highly coupled modules.
Dingwei planned to design the traits in a top-down way. He is going to analyze what the upper layer modules need and implement a just-enough interface using the underlying modules.
CKB Protocols in Web Browsers
Light clients enable trustless blockchain interactions without requiring the overhead of running a full node and open up new kinds of applications.
Quake leads a team working on the light client demo. They have been working on running CKB protocols in web browsers via Tentacle WASM because the demo will be run in-browser.
Channel Network
Channel networks can maximize the throughput and minimize the latency of transaction processing, enhance transaction privacy, and can even provide certain interoperability for blockchains.
The channel network team has been working on proposing the general payment channel specification.
