[1/12] 🧵 @Conste11ation ( $DAG) is a highly scalable and secure distributed ledger technology (DLT) that achieves zero/low trust interaction platforms, peer-to-peer (P2P) internet overlay protocols, and platform-neutral computation description language. Let's dive in! 🚀
[2/12] 🔐Zero/Low Trust Interaction Platforms (Shared Security):
@Conste11ation creates a shared security environment through its L0 consensus mechanism. L0 allows metagraphs (custom consensus apps) to maintain their own L1 layer while sharing L0 security with the global network.

[3/12] 🌐This shared security model reduces the need for trust as metagraphs inherit the security of the global L0 network. It's similar to Polkadot's shared security model, where parachains share security provided by the relay chain. #cryptocurrency #DAG

Decision trees based Machine Learning models are some of the best performant algorithms in eras of predictive capability, especially on small and heterogenous datasets.

They also provide an unparalleled level of interpretability compared to all other non-linear algorithms. However, they are very hard to optimize on Von Neumann architecture machines due to their non-uniform memory access patterns.

In groundbreaking work published in Nature Communications a team of researchers has shown that analog content addressable memory (CAM) devices with in-memory calculation can dramatically accelerate tree-based model inference, as much as 10**3 over the conventional approaches 3/4
Fees on #StarkNet
The idea is to compute the L1 footprint of a transaction, including 2 dimensions:
- computational complexity: the heavier the transaction, the larger its portion in the proof verification cost
- on chain data: L1 call data cost
Let see how it works 🧵

The size of #NLP models have increased enormously, growing to millions, or even billions, of parameters, along with a significant increase in the financial cost and carbon emissions.
The cost associated with training large models limits the #AIresearch community's ability to innovate, because a research project often needs a lot of experimentation.
Consider training a top-performing #LanguageModel on the Billion Word benchmark. A single experiment would take 384 GPU days (6 days*64 V100 #GPUs, or as much as $36,000 using AWS on-demand instances)

Drawing Innovation: @illumina Super-Resolution Optics
Recently, $ILMN unveiled the NextSeq 2000, a mid-throughput sequencer w/ a ~2X reduction in operating costs ($/GB).
We think the upgrades inside the NextSeq 2000 may soon enable a $100 clinical-depth human #genome.
But how?

We think the upgrades inside the NextSeq 2000 may soon enable a $100 clinical-depth human #genome.
But how?
The cost savings come from (1) a new upfront #chemistry and (2) super-resolution optics. We think @illumina will use real-world customer data on the NextSeq 2000 to optimize 1 and 2, then possibly upgrade the #NovaSeq line.
