If many people need to access this global state, and that state is stored in the datum of a single UTXO, it creates a race among users to be the first to spend that UTXO. Each time someone wins that race, it resets everyone else back to square one: they have to find the new UTXO, construct a new transaction, and submit it.

SundaeSwap’s Solution

We’ve chosen a solution that differs from those above; Very soon we will be ready to pull back the curtain and reveal how it works. Given the nature of the recent discussion, we want to do so with receipts, and are currently preparing load tests to demonstrate exactly how well our scaling solutio...

Potential Solutions

Today, there appear to be two categories of solutions to this problem: either design your protocol to tolerate segmentation of your state, or aggregate interactions with that state.

Misconception 3 : The only way to solve this is through centralization.

Centralization is a way to solve this problem, but it is not the only way. See below.

Misconception 2 : Only one user can interact with a smart contract per block/transaction.

Also not true; the point of contention is around the UTXO, but many UTXOs may be governed by the same smart contract.

This fundamentally comes down to the shift in thinking from ...

Misconception 1 : Cardano is flawed because it only allows 1 transaction per block.

In fact, it is quite the opposite. Cardano allows many hundreds of transactions per block.

Instead, it is accurate to say that Cardano allows a given transaction output to be spent a s...

Cardano and eUTXO

Cardano chose, instead, to improve on the UTXO model enough that dApps themselves could make these tradeoffs between independent operation and centralization. The eUTXO model that Cardano led the research on introduces three new primitives for smart contracts: The datum, the redeemer, and the val...

btc vs eth transaction differences

The difference between these two can be analogized to the difference between the cash in your pocket and the balance in your bank account.

Access to global information, such as price, is trivial in these models. However, there are a lot of downstream negative side effects of this choice.

Many people have pointed out that Cardano’s choice of eUTXO can create issues when porting protocols. This is certainly true; we alluded to this in our whitepaper many months ago. Similarly Lars Brünjes, the Di...

"Patience wins in an impatient world. When everyone else is in a hurry and distracted by the latest Tweetstorm, sitting back and merely observing the planet’s slow, arcing trajectory–and noticing it has been unmoved by almost anything that has happened lately–is the supreme advantage, both in ...


We are attracted to devices that track our activities

Global sales of wearable devices that track daily activity and allow users to get notifications will reach $1bn by 2022.

One neuroscientist says part of the attraction for users is the way many of these apps 'reward' users. When you see your step count or sleep hours in an app, it...

Repeat, repeat, repeat

To avoid miscommunication, repeat or summarize their words back to them in a form like, “What I’m hearing you say is…” It creates a feedback loop that allows someone to course correct or dial it back.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
