#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.

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.

#blockchain
3/10 Layer 1 blockchains are designed to be

✅secure
✅decentralized
✅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.

1/11
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
2/20
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
3/20
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

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)).

1/4 We love ♥️developments that, through their simplicity, can solve a problem with astonishing ease.

🙋🙋‍♀️How many of us end up holding small amounts of various tokens in our wallets that never seem to grow?

#xDustconverter has long since offered us an interesting solution. Image
2/4 Something as simple as:

✅ going to xdustconverter.com
✅connecting your wallet
✅selecting the coins you want to convert to eGLD
✅and clicking "convert small amounts"

will allow you to make a profit from those small amounts you store.

[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

- Nasdaq
- #AlephZero new projects
- #SmartContracts launching

To those of you living in a cave for the last few weeks here's a recap of what has been going on;
Due to the Banking crisis and the bankrupcy of several big Banks like Crédit Suisse, Silicon Valley Bank and now Dutsche Bank coming next, markets have seen increased volatility...
As a matter of fact as the news hit the markets we saw panic selling and the mother of all bear traps where #bitcoin fell to the 19k's and was followed by a rapid recovery and pump to the 28k's as smart money moves from Banks to #Crypto
