Smart contracts 2.0 are now available on the Hedera testnet. ✅ Previewnet ✅ Testnet 🔜 Mainnet Here's three things you need to know. 🧵

Mikerah Nigel Smart Marcel Keller The title of Yehuda Lindell's talk at the upcoming TPMPC 2022 says it all "OMG! People are Actually Implementing my MPC Papers!" 😂😂😂 (sign up if you haven't already! multipartycomputation.com/tpmpc-2022/202… )

#QuantumComputing poses significant security threats to #DLT. While Hedera is CNSA standard compliant and is generally considered safe from future quantum threats, we are closely following National Institute of Standards and Technology's ongoing efforts to standardize post-quantum cryptography. hedera.com/blog/post-quan…

We show how incremental timed-release encryption can be used for sealed-bid auctions or scheduled transactions. Check out our paper eprint.iacr.org/2021/800.pdf to appear at ACM CCS 2025

Our paper (eprint.iacr.org/2022/1632.pdf) studies weighted cryptosystems where parties are assigned a weight, and the trust assumption is that a certain fraction of the total weight is honest. Standard virtualization gives multiplicative overhead in the weights, but ours is additive!

1/ Introducing the Decentralized Recovery (DeRec) Alliance: a collaboration between @SwirldsLabs, Algorand Foundation, @HBAR_Foundation, The Hashgraph Association, & @DLT_Science to develop a standard which will greatly simplify the recovery & adoption of #DigitalAssets. prnewswire.com/news-releases/…

We are excited to announce that Ripple and XRPL Labs 🪝 have joined Swirlds Labs and Algorand Foundation as Founding Members of the Decentralized Recovery Alliance, with two-year seats on the Technical Oversight Committee providing input on governance and core Alliance policies. #DeRec

Short blog post summarizing a recent strawman construction of a multiverse threshold signature scheme by Leemon Baird, Sanjam Garg, Rohit Sinha, Mingyuan Wang et al: alinush.github.io/2024/05/01/bai… An interesting open Q: How _efficient_ is it to reveal those f(-1), ..., f(-(n-t)) points?

Discovered in our CWI library: the proceedings of Crypto'82 (which are still behind a Springer paywall). With a nice picture on the backside:

This is hilarious. Engineers are competing who creates the worst Ul on Reddit. I think the winners are (thread)🧵 1/ Enter your phone number

Fireside chat with Dr. Leemon Baird & Rohit Sinha 🔥 Leemon and Rohit are unpacking what it takes to build a public network that’s fast, secure, and built to last. Scalability isn’t meaningful unless it’s grounded in strong cryptographic guarantees & verifiable trust.
