Most recents (24)

With #smartcontracts on the scalable and feeless #Shimmer network, we will see the rise of frictionless, decentralized and scalable #web3 economies. 🚀

We gathered our six major use cases for you! 🧵👇 Image
1) Energy management

Shimmer is well suited for energy markets, real-time data management and moving #carboncredit or #renewable energy certificates without transaction costs.
2) Digital Identity

Shimmer is ideal for #NFTs, native tokens and smart contracts to interact with digital identities. Identities can control other identities, which enables flexible modeling.

(2/11) #SmartContracts are computer programs or protocols that automatically execute #transactions stored on a #blockchain when certain conditions are satisfied. 🤓
(3/11) Smart #contracts can be thought of as digital "if-then" statements made by two or more parties. 🤝 When the expectations of one party are met, the #contract is said to be fulfilled. 💼 #SmartContracts #Cryptocurrency

(2/11) 💻 #Blockchain is a shared #ledger or repository that computer #subnets may access. It is similar to a #database, but it is secure and #decentralized. #Cryptocurrency systems like #Bitcoin use blockchains to keep a secure and decentralized database of transactions. 🔐
(3/11) 💡Blockchain eliminates a #centralized command structure, allowing #data sharing among parties without needing a centralized system or administrator. It is #secure and #data can't be corrupted or destroyed by anyone with access to the main database. #FinancialTechnology

Understanding Ethereum and its role in DeFi
1/ Ethereum is a global, open-source platform for decentralized applications. It allows for the creation of smart contracts that control digital value through a set of predefined criteria.
2/ These smart contracts are the building blocks of decentralized applications (Dapps) that provide financial services, known as DeFi.

@uPark_network is on a mission to create a sustainable mobile parking reservation #dApp for areas with high concentration of cars by improving visibility and guaranteeing parking availability across Europe.🇪🇺

Let’s see how they achieve this using @MultiversX #Blockchain

🧵👇
2/
Founded by @JakubSm_BCT & his team, the core of @uPark_network is the $UPARK token and the $LKUPARK (Locked-UPARK) token, the one received during pre-sales.

The $LKUPARK has limited transferability programmed via 3 #smartcontracts: #Swapping, #Vesting & #StakingRewards 🤯

👇
3/
There is also the uPark Genesis Pass (UGP) NFT collection ticker: UGP-e71806

And a lot more details on their Whitepaper (a new version TBA soon) and on ElrondBuilders.com, where we added this project at:

More or less a year ago the #IOTA Foundation announced two new networks.

#Shimmer a staging network and #Assembly a permissionless Layer2 network building on top of #IOTA.

Let's put together everything we know and speculate about their adoption and price.

A👇🧵

1/44
Okay so first we need to get a little bit of an overview of everything #IOTA.

We need to separate between networks and technology upgrades. This is necessary to keep a clear picture of everything we will talk about in this Thread

2/44
Simplified the #IOTA Foundation is marketing two major updates that are coming to their tech.

1) #Stardust - An update enabling the layer 1 (#DAG) to natively support customs assets (Tokens, NFTs) and be the trust anchor for layer 2 #sc networks.

The #IOTA community has been lately very impatient about the release of the #ShimmerEVM which follows the #Stardust upgrade.

But what is #Stardust? What is #ShimmerEVM? What do they bring to #IOTA / #Shimmer and why are people so excited about it?
A 🧵👇 (1/33)
While trying to put a thread together on the different #IOTA ecosystem networks and their respective usecase, i realized we first need to get a in depth understanding of #Stardust and #ShimmerEVM. So let's not waste time and dive right into this 🐰🕳️

(2/33)
#Stardust ⭐ is - like IOTA 2.0 - a technology upgrade coming to the #IOTA baselayer. It is here to enable mainly one thing, it shall
finally empower the community and everyone else, to use the network and build on it.

With the #Shimmer token on sale at the moment, did you load up your bags already? 💰

In case you are wondering what role the $SMR token might play...

Read on to learn more. FOMO guaranteed! 🧵👀
The Shimmer token powers #smartcontracts built on top of the Shimmer network.

Using #IOTA Smart Contracts, developers can build #dApps by using Solidity, Rust or Go. This allows for endless possibilities!
#DeFi unchained, powered by a feeless base protocol and fully composable and interoperable smart contract dApps.

With the new possibilities it provides to developers, the Shimmer network is the place for new dApps that aren't possible anywhere else.

1/5 Did you know that crypto tokens and coins are not exactly the same thing?

I will try to explain how to distinguish a #coin from a #token and their different uses.
2/5 Many people call Token and Coin “#cryptocurrency” interchangeably, they are not the same thing. Although both use distributed ledger technology (also known as #blockchain technology), there are some significant differences between a coin and a token.
3/5 Coins are a form of digital currency often native to a blockchain, with the main purpose of storing value and functioning as a medium of exchange.
When #Bitcoin was created, it was envisioned as a replacement for traditional fiat currencies.

Yesterday @jonastheis_ joined a space with @CryptoMiners_Co and talked about #IOTA 2.0

He did provide very valuable information about the development of #IOTA2, that i want to put together for you.

Link to the space:

🧵👇 Image
1/40

Let's start with an overview about everything #IOTA.

The #IOTA Ecosystem consists of 2 live networks 🌐🟢
and one running development network 🌐🟠

1) 🟢 The #IOTA 1.5 Network
2) 🟢 The #Shimmer Staging Network
3) 🟠 The #IOTA2 Development Network
2/40

1) The IOTA 1.5 Network is the acutal running #IOTA network. The token is $MIOTA. It still has a coordinator (COO). A centralized unit issuing milestones in the dag. This network is able to perform value and data transactions. It has no #SmartContracts (sc) and no #NFTs yet Image

(2/13) #Tokens or money are distributed to #wallet addresses as marketing in a #bitcoin #airdrop. Small quantities of the new virtual #currency are distributed or traded for a minor favour, such as retweeting a message from the corporation that produced it. 🎟️💵
(3/13) Participants who are interested in receiving an #airdrop signal their willingness to do so in a normal #bitcoin airdrop. To obtain it, they must submit a verified wallet address. 👛✅

2/ Ähnlich wie bei MetaMask ist #GemWallet eine "Browser-Extension"-App für den einfachen Umgang im #Web3, jedoch nativ auf dem #XRPL.

Funktionen sind z.B.:
• GemWallet #API (Brücke zwischen Websites und der Browser-Extension)
• Bezahlungen

1/ In November 2022, Skyward Finance became the first project in the NEAR ecosystem on the Rekt leaderboard of the biggest #DeFi hacks. The attacker exploited vulnerabilities in the Skyward contracts to drain approximately $3.2 million in tokens from the project. #cryptocurrency
2/ The Skyward hack was made possible by a vulnerability in the redeem_skyward function within the project’s #SmartContracts. This function allows users to redeem the SKYWARD tokens they have earned for wNEAR tokens stored within the contract.

#Hacked #Blockchain #Security
3/ The redeem_skyward function failed to properly validate token_account_ids when processing redemptions. The function verified that a provided token_account_id was valid but not that it was unique. The attacker exploited this vulnerability.

(1/6) Proxy contracts are used all the time in @solidity_lang for many different reasons.

In this post I explain the concept of ‘storage collisions’ and how to avoid them when it comes to proxy contracts.

May your storage be collision resistant from this day forth 💥 🧼 🧽 Image
(2/6) Storage collisions suck.

They’ll cause all kinds of bugs in your application. 🐜

Many libraries like @OpenZeppelin handle a lot of the internal details for you; but understanding what’s going on under the hood is great to improve your @solidity_lang skills.
(3/6) I know there’s a lot to digest in this diagram but many of the concepts are topics that we’ve already covered.

"The 21st Century Question: Emergently Engineering the Future"

Follow this 🧵 today and tomorrow for highlights from our 2022 #AppliedComplexity Network and Board of Trustees Symposium:

santafe.edu/events/annual-…

#Web3 #Cities #Polarization #EmergentEngineering #Decentralization
We start with a talk by SFI President David Krakauer:

"Would anyone care to guess why we're so GOOD at building transistors and so CRAP at designing drugs?"

"This thing [points to transistor] lives in a centralized system. This thing [points to cancer drug] lives in US."
"I'm going to pick on economics, because we like to do that at SFI. 'Ooh, look at that cover! So techy. Global, heat maps...' But here's 'Networks' [in the textbook]. THAT'S IT. Here's '#ComplexityEconomics.' NOTHING."

▶️Le FBI et la CIA chercheraient à découvrir son identité, pendant que la légende #SatoshiNakamato, 20° fortune mondiale, continue à faire couler beaucoup d’encre

Toute hypothèse est possible à ce sujet

Étudions donc le phénomène avec un esprit cryptique.

@Jokaver x @0xTwareg
@Jokaver @0xTwareg - Et si un lobby technologique & industriel, la CIA ou le WEF se cachait derrière cette légende ?

Comment ? Pourquoi ?

▶️ Revenons aux origines de l’émergence de la cryptographie :

#Bitcoin est né dans les méandres de la crise financière de 2008... Image
@Jokaver @0xTwareg Alors que l’économie, le système financier & bancaire mondial étaient au bord du gouffre.

Afin d’éviter l'implosion financière imminente, les gouvernements ont opté pour des politiques de Quantitative Easing, misent en place principalement par l’activité des banques commerciales ImageImage

ICYMI: Did you know? We already have a fully functional #smartcontract test chain deployed, since releasing the first #Stardust compatible version of ISC (@iota Smart Contracts) ✨ 🧵 ⬇️
blog.shimmer.network/shimmer-based-…
We need your help testing out ISC - and you won't even have to run your own Smart Contract node. Deploy your own #SmartContracts and interact with others, so we can advance the tech faster and further than ever before 🏗️
To make it accessible, we deployed a test-chain on the #Shimmer Beta network along with helpful tooling ⚒️ . The test-chain consists of several load-balanced #Wasp nodes forming a committee, communicating to the Shimmer beta network via their own local Hornet nodes 🐝 .

Today I’ll show you how we can pay for Rent and Living Expenses with our #Bitcoin without selling them.

Using #ZERO from @SovrynBTC , a #DEFI platform running on @RSKsmart , a sidechain that uses #BTC as its native currency as it is merged mined by the BTC miners
2-10
All we need to get started is some #Bitcoin and an @RSKsmart enabled wallet, I personally use @Liquality_io , but @MetaMask or @defiantApp work as well.

We exchange our #BTC for #RBTC using the #FastBTC bridge from @SovrynBTC at live.sovryn.app/fast-btc/depos…
3-10
The #RBTC is always backed 1 to 1 with #BTC and can be traded back and forth

This maintains their value, and once in the @RSKsmart blockchain we can take advantage of #SmartContracts and #DEFI platforms like @SovrynBTC , @moneyonchainok and @tropykus secured by #BTC
