What are stealth addresses, and how do they work?

Stealth addresses in cryptocurrencies act like secret codes for transactions, providing enhanced privacy by generating unique addresses for each payment.

The purpose of crypto stealth addresses is to enable privacy for each transaction, concealing the recipient’s identity and transaction history.

Crypto stealth addresses are a privacy-enhancing feature in blockchain technology that lets users receive money anonymously. Unlike conventional public addresses, stealth addresses provide distinct, one-time addresses for every transaction. The recipient’s actual address is kept secret when a sender transfers funds using a stealth address; the transaction is broadcast to the network.

Blockchain media authentication app eyes news journalism as primary use case

Tapping into underlying blockchain infrastructure, Nodle’s Click application allows users to authenticate media content for various use cases.

Decentralized infrastructure network provider Nodle has released the first version of its blockchain-based media authentication application called Click, which could prove useful in combatting artificially generated media and fake news.

As previously reported by Cointelegraph, Nodle has developed a software development kit (SDK) for its ContentSign solution, which cryptographically proves the integrity of data captured by mobile devices using blockchain technology.

The Click application supports the Coalition for Content Provenance and Authenticity (C2PA) and is a member of the Content Authenticity Initiative (CAI). The latter is a project led by Adobe and the Linux Foundation to create a future standard for media attestation.

Enterprise blockchain Coti set to become Ethereum privacy-centric layer 2 in 2024

Coti will look to provide privacy-focused functionality to the Ethereum ecosystem as a new layer-2 protocol.

Enterprise-grade blockchain platform Coti is set to transition protocol to become a scalable, privacy-focused layer-2 on Ethereum in 2024.

An announcement shared with Cointelegraph outlines how Coti will shift from a standalone protocol to an Ethereum layer 2 to bring its privacy features to the broader ecosystem. Coti v2’s features a cryptographic approach called garbled circuits, which allows transactions to be processed without exposing sensitive information and data.

Drawing from the field of multi-party computation (MPC), garbling protocols enable two or more parties to jointly compute a function while keeping both their inputs and intermediate variables private.

40% of crypto game devs are banking on trad gaming in 2024

More than a third of survey respondents believed the blockchain gaming industry benefited most from traditional game studios adopting Web3 tech in 2023.

Nearly 40% of blockchain game developers believe that traditional gaming studios will be one of the biggest positive driving forces for the Web3 gaming sector in 2024.

In its “2023 State of the Industry Report,” released on Dec. 12, the Blockchain Gaming Alliance (BGA) found that 37.8% of respondents believed Web2 studios launching new games in Web3 or applying blockchain elements to existing titles would help push the industry forward in 2024.

When asked to identify the biggest positive driver in 2023, 19.8% of respondents cited traditional game studios launching nonfungible token games, while 15.2% pointed to the same studios transitioning into Web3.

Block size and scalability, explained

Block size and scalability trade-off involves optimizing transaction capacity while ensuring network performance amid increasing demand.

Block size is important for maximizing storage efficiency and transaction throughput in file systems and blockchain contexts.

The amount of data processed or transferred in a single block within a computer system or storage device is referred to as the block size. It represents the basic unit of data storage and retrieval in the context of file systems and storage.

Can cryptocurrencies be frozen on a blockchain?

Cryptocurrencies can be frozen on a blockchain under certain legal, regulatory and technical conditions.

Frozen funds typically mean access to such funds has been restricted or temporarily halted.

Several factors, such as technological errors, security precautions, disagreements, investigations and regulatory compliance, can lead to such circumstances. So, can a crypto exchange freeze your account?

How blockchain improves daily healthcare routine, explained

Blockchain enhances daily healthcare by securing patient data, streamlining coordination and minimizing errors for efficient care delivery.

The significance of blockchain in the daily healthcare routine

Blockchain has the potential to revolutionize healthcare by preserving data integrity, fostering better teamwork, and increasing patient care — even in the face of ongoing difficulties with scale and integration.

Blockchain technology has the potential to completely transform healthcare practices.

Blockchain makes it easier to create a decentralized ledger that safely keeps patient data private and permits authorized access.

Additionally, the technology can strengthen clinical trial integrity, guaranteeing the reliability of outcomes and advancing medical research.

How can blockchain prevent the counterfeiting of drugs in the pharmaceutical supply chain?

Blockchain technology’s intrinsic transparency and immutability are vital in the fight against drug counterfeiting in the pharmaceutical supply chain.

Blockchain follows the movement of pharmaceuticals from production to distribution, providing an immutable record of every stage along the way by generating an unchangeable ledger of transactions.

Every drug batch is registered as a distinct block on the chain, holding important data, including quality certifications, shipment information and production details.

KuCoin pledges $20K grant to TON Foundation for ecosystem development

The funding will support TON ecosystem projects, research and development efforts, community-building and marketing activities.

KuCoin Ventures, the venture arm of Seychelles-registered crypto exchange KuCoin, will provide grants to The Open Network (TON) blockchain platform, including an initial $20,000, to support the growth and expansion of the TON ecosystem.

According to a Dec.

Ian Wittkopp, accelerator head at TON Foundation, said the grants from KuCoin aid them in continuing to support real-world blockchain solutions in payments and gaming within its ecosystem.

“Today’s partnership with KuCoin Ventures is an acceleration point in the momentum of mini-app development on the The Open Network… KuCoin Ventures’ efforts align with TON’s vision of a more accessible and decentralized digital future for everyone.”
