It was a huge month for blockchain Rust! It seems like we’ve all been productive sitting at home hacking. We’ve seen so many interesting developments #rust #blockchain #hacking rustinblockchain.org/newsletters/20…

🥳 rust-analyzer is officially released 🎂 rust-analyzer.github.io/blog/2020/04/2… Use it and, if you like it, sponsor on opencollective.com/rust-analyzer/!

For a reason, I need to start w/ a GraphQL schema assembled at runtime and serve it with Rust modules but from dynamic data sources w/o resorting to static types. Juniper crate doesn't seem so appropriate for my purpose. Is there anybody who can share one's experience? @rustlang

Super excited to be the first ones to implement the #ICS standard along with @cosmos! 🔥🔥🔥 Check out @JhyKodebox's intro to our implementation process and results! #CodeChain #tendermint #cosmos

My first #rustlang crate is out! crates.io/crates/intertr…. It enables direct inter-trait casting of trait objects. It's written for use in @codechain_io foundry project w/ key ideas taken from traitcast crate. Intertrait is intended to enhance in ergonomics over traitcast.

Now we have python SDK as well.

@codechain_io However, when verifying block headers, BLS was faster than Schnorr, as the number of validators grows. Check out the details of our research here medium.com/codechain/adap…

#BLS signature aggregation allows you to aggregate several digital signatures into one. @codechain_io Foundry is planning to adopt it to reduce the space consumed by signatures stored in block headers for #Tendermint. We succeeded to reduce from 1920 to 48 bytes.

@codechain_io Benchmark tests that compared the performance of the #BLS scheme with #Schnorr scheme tell us that the BLS scheme was 8 and 57 times slower than the Schnorr scheme when signing and verifying a single signature, respectively.

Rust IDE support helps rust-analyzer to move fast:

I just posted a new article to Medium which discusses #front_running_attacks and also takes a look at the #CodeChain DEX protocol. If you're interested, make sure to check it out at 👉🏻 link.medium.com/rACcYNw7L3

We are excited to announce Tenderbake, a Classical BFT Style Consensus for Public Blockchains. The paper was published in collaboration with @CEA_List. Learn how this could be included in a future #Tezos protocol upgrade. arxiv.org/abs/2001.11965 #Blockchain #POS

Great list of career tips from @sama How To Be Successful (At Your Career, Twitter Edition)buff.ly/36SRWro

Jesse chung from @Tezos_Korea is giving speech now! 🤓 #Trustless2020 viewing party @nonce_community. @CodaProtocol @dsrvlabs @DystopiaLabs @TheBAFNetwork @stakedotfish #Tezos @tezos

In intro to Inter Blockchain Communication (IBC) and InterChain Standards (ICS) written by @JhyKodebox. It's an easy to read post for those who are new with #IBC and #ICS. Take a look! medium.com/codechain/ibc-…

Recap of last week's CodeChain TechTalk where we shared the implementation details and benchmark results of #Tenderand and #VeriSync and announced #Foundry, a framework for building custom blockchains that supports IBC. Check out the details! medium.com/codechain/mont…

After months of R&D, I am happy to share #Tenderand, a randomized leader election in #Tendermint that we have implemented on #CodeChain. The test results show that it can effectively defend against DOS attacks in public blockchains. Here is my entry! medium.com/codechain/tend…

Full house at our 3rd CodeChain Tech Talk! Lots of questions and lots of discussions till late night hours 🔥🔥🤜🤛💪💪
