#EUCI, with other 5 organisations and 55 signatories, has written an open letter addressing concerns regarding the #DataAct.

We call on lawmakers to reconsider and clarify certain aspects of it, to ensure neutrality and legal certainty in the #blockchain industry. Image
🟣 Article 2(16)

The current definition of 'Smart Contracts' is broad, and we fear it may lead to unintended consequences for existing #SmartContracts on public #blockchains, such as Ethereum, Avalanche, Cardano, Cosmos, IOTA, NEAR, Chromia, and Polkadot. Image
We propose three alternative solutions to bring more legal clarity:

substituting 'Smart Contract' with 'Digital Contract', clarifying the scope of Article 30, or limiting Article 2(16) to privately operated and permissioned electronic data records.

Short thread on some common Web3/DeFi vulnerabilities:

⚡️ Understanding the role of flash loans in DeFi security is crucial.
These powerful tools enable arbitrage opportunities but can also introduce vulnerabilities.

Learn how to identify and mitigate risks associated
with flash loans to safeguard the integrity of decentralized Web3 protocols.

🔏 Reentrancy attacks pose a significant threat to smart contracts.

By exploiting recursive calls, malicious actors can drain funds.

Implementing proper checks and using techniques like the...
"checks-effects-interactions" pattern can help prevent reentrancy vulnerabilities. Stay secure!

🔒 "Time-dependent attacks" may sound unfamiliar, but they can compromise the security of smart contracts.

Attackers exploit variations in block timestamps to manipulate...

1/10 Blockchain tech is composed of different layers, and #Layer1 is a fundamental part of this ecosystem.

It refers to the underlying infrastructure that serves as the foundation 4 a blockchain network, providing the basic functionality and sets the rules 4 the entire system Image
2/10 Layer 1 blockchains, like @MultiversX, are often referred to as "base layer" or "on-chain" solutions. 📋

They handle key functions like:

✅ transaction #validation
#consensus mechanisms
✅maintaining the overall security and integrity of the blockchain.

3/10 Layer 1 blockchains are designed to be

✅and immutable.

They have their own native #cryptocurrency 🪙 (in @MultiversX is $eGLD) and can support a wide range of applications and #smartcontracts.

Today, I'm going to walk you through the functions of the MultiSig Wallet smart contract on #Starknet. Brace yourself for an exciting dive into the world of #Cairo1 and #SmartContracts.

The constructor function is the first function called when the contract is deployed. It takes an array of owners & a required number of confirmations as input. It adds each owner to the contract, & sets up the number of confirmations needed to approve a transaction.

2/11 Image
The submitTransaction function allows only wallet owners to propose transactions. It accepts an address, a value. A new transaction with these details, marked as not yet executed, will be added to the transactions list.

Absolutely eye-opening talk about the intricate nature of things #Evernode, #Hooks, #SmartContracts, and #Codius from the folks who REALLY understand it.

I also really liked how @xrpl365 arranged the "lecture" since he clearly knew what questions needed to be answered. 💪
I'd also want to mention that @ShortTheFOMO was able to wonderfully clarify his opinions on certain questions I had in the back of my mind.

Seeing Hooks, XRPL, and Evernode in a way that connects to the "simple foundation" that is XRPL helped me understand it. Thanks! ☺️
It was also amusing to me to hear @xrpl365 state out loud what I was thinking about "immutability" while thinking about altering the smart contract as you can on, say, Casper.

Evernode, or more specifically, the Hotpocked dApp, allows you to choose your design:

Let's take a deep dive into the intricacies of Internet Protocols (IPs) like TCP/IP, their history, and how these systems parallel to the Ethereum blockchain ecosystem.

This thread is technical - buckle up! #InternetProtocols #Ethereum
TCP/IP, the backbone of the internet, has its roots in the ARPANET project of the 1960s-70s.

It's a suite of protocols for data transmission and routing. TCP/IP is layered, each with its specific tasks:

Network Interface, Internet, Transport, and Application. #TCP_IP
The Network Interface layer (eg, Ethernet) takes care of the physical transmission of data.

Internet layer (eg, IP) ensures data packets are routed correctly

Transport layer (eg, TCP) guarantees reliable transmission

Application layer (eg, HTTP) is for user interactions

@staking_agency has released a @MultiversX #golang SDK, which optimises the time and efforts of the #MultiversXBuilders

It contains a set of free tools and .go packages for an easier interaction with #MultiversX #blockchain and its #smartcontracts

👇 Image
The #SDK can get data and callback from various areas of the #blockchain, such as:
- Accounts & @xPortalApp Wallets TXs for $EGLD & #ESDT
- Exchanges: @xExchangeApp & @Elrond_One
- #staking, ESDTs, #telegramBot and examples for each of the modules.…

A tool that generates #golang language bindings to a @MultiversX #smartcontract, called ABI2GO - is also available in the same #SDK package as beta version.

@staking_agency has added this tool on at:…

Have you ever wondered what sets CREATE apart from CREATE2? Let's find out..

In Solidity, `create` and `create2` are important opcodes for smart contract creation. `create` deploys a new contract, while `create2` creates a contract at a deterministic address based on input.
Here's an example of how `create` works:

This deploys a new instance of `NewContract` and returns the address of the new contract. The formula for determining the contract address is `keccak256(sender, nonce).`

#solidity Image
create2 is more complex. It calculates a deterministic contract address using four inputs: sender address, salt, bytecode, and constructor arguments. The formula is keccak256(0xFF, sender, salt, keccak256(bytecode)).

El artículo se titula “Las monedas estables respaldadas por BTC serán una parte integral de la economía de #Bitcoin "

Comenta que “Bitcoin como cobertura contra la degradación monetaria es solo la mitad de la batalla.”, más allá de que se utilice a #Bitcoin como reserva de valor o un refugio contra la inflación, no estamos cerca de cesar la lucha. ⬇️
A medida que la deuda pública se vuelve parabólica y una nueva subida de las tasas de interés se vuelve inviable sin quebrar la economía, David, ve probable que los gobiernos utilicen los impuestos para hacer frente a la inflación.⬇️

[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

Currently, contracts available to deploy are for ESDT and #SFT creation, but others will follow, such as staking, auction, airdrop or NFT creation.

There are also options to send ESDT/NFT/EGLD, purchase ESDT/SFT, vesting and claiming ESDT tokens.

The ESDT #smartcontract allows you to create, import, send and create a sale for your ESDT token.

Vesting and Sale is customizable and the #smartcontract can be updated, if needed.

Same for #SFT, plus support for multi-collections, sales & simplified built-in functions.
