A. A logic gate usually takes in 2 inputs and gives out 1 output. The inputs and outputs are binary values, meaning they can be both 1 and 0. B. A logic gate usually takes in 3 inputs and gives out 2 output. The inputs and outputs are binary values, meaning they can be 1 or 0. C. A logic gate usually takes in 2 inputs and gives out 6 output. The inputs and outputs are binary values, meaning they can be both 1 and 0. D. A logic gate usually takes in 2 inputs and gives out 1 output. The inputs and outputs are binary values, meaning they can be 1 or 0. Answer: D A logic gate usually takes in 2 inputs and gives out 1 output. The inputs and outputs are binary values, meaning they can be 1 or 0. A XOR logic gate takes in 2 binary inputs and gives out a high output ONLY when the inputs are different. Meaning, if A and B are inputted to a XOR gate then the out C will be 1 ONLY when A is not equal toB.

Hybrid D. Private Answer: A Permissionless – anyone can join Anyone can run a node, run mining software/hardware, access a wallet and write data onto and transact within the blockchain (as long as they follow the rules of the bitcoin blockchain). There is no way to censor anyone, ever, on the permissionless bitcoin blockchain. Reference: https://medium.com/@dustindreifuerst/permissioned-vs-permissionless-blockchains-acb8661ee095 Question: 189 Your company working for is now considering the blockchain. They would like to perform a POC with R3 Corda. The CIO was memorizing about different blockchain consensus algos and would like to understand what type of consensus algos is used with Corda. What is the best answer? A. R3 Corda is a pluggable blockchain and allows the enterprise flexibility B. R3 Corda is a byzantine fault tolerant blokchain C. R3 Corda is a proof of stake based blockchain D. R3 Corda is a proof of work based blockchain Answer: A Corda does not share the same requirements as Bitcoin: they require absolute certainty over transaction finality and we need to know who their counterparts are. So they had the freedom – and took this opportunity – to solve the consensus problem in a different way. In particular, Corda solves the privacy issue in a number of manners, primarily by allowing for separation of consensus into a service which they call the Notary Cluster. Corda was designed for business from the start. It has no cryptocurrency built into the platform and does not require mining-style consensus, which imposes great cost with little business benefit. Question: 190 Your customer is an enterprise that is focused on financial sectors. What type of blockchain would this customer likely want specified for their enterprise? A. Permissionless B. Decentralized C. Hybrid D. Permissioned Answer: D Sometimes referred to as "private" blockchains, you are required to have some sort of permission to access any or parts of that blockchain. There are a multitude of variants and hybrid permissioned/permissionless blockchains that exist. Reference: https://medium.com/@dustindreifuerst/permissioned-vs-permissionless-blockchains-acb8661ee095 Question: 191 Which is the following is the metaphor that describes a logical dilemma that plagues many computer networks? A. Neo Generals’ problem B. Byzantine Generals’ problem C. Byzantine Admirals’ problem D. Renaissance Generals’ problem Answer: B BFT is so-named because it represents a solution to the "Byzantine generals’ problem," a logical dilemma that researchers Leslie Lamport, Robert Shostak and Marshall Pease described in an academic paper published in 1982 Reference: https://www.nasdaq.com/article/byzantine-fault-tolerance-the-key-for-blockchains-cm810058 Question: 192 The key difference between encryption and hashing is that encrypted strings can be reversed back into their original decrypted form if you have the right key?

A. 1,000,000,000,000,000,000 B. 1,000,000,000,000,000 C. 1,000,000,000 D. 10,000 E. 1,000,000,000,000 Answer: AB Reference: http://www.btcsatoshi.com/ http://ethdocs.org/en/latest/ether.html Question: 197 In the Proof of Stake(POS) algorithm the miners are really known as ___________? A. Notary B. Oracle C. Forgers D. Minters Answer: C Proof of Stake has the same goal as proof of work""to validate transactions and achieve consensus in the chain""and it uses an algorithm but with a different process. With proof of stake, the creator of a new block "is chosen in a deterministic way, depending on its wealth, also defined as a stake." Since in a proof of stake system, there is no block reward, but the miners, known as forgers, get the transaction fees. Proponents of this shift, including Ethereum cofounder Buterin, like proof of stake for the energy and cost savings realized to get to a distributed form of consensus.

The X account (formerly Twitter) of blockchain security company CertiK has been compromised with bad actors posting a phishing link to a wallet drainer. On Jan 5, it was revealed that CertiK’s X account was a victim of a phishing attack with several calls from the wider community to avoid engaging the links posted during the incident. Blockchain security firm, Wallet Guard flagged the incident noting that the hackers are posting fake masked Revoke Cash links to a wallet drainer with other users adding that engaging with the links could lead to asset losses. The hackers accessed the X account and posted a Uniswaps router contract with warnings of a re-entrancy exploit asking users to utilize Revoke Cash to “revoke” previous approvals. “WARNING: Our team has found the Uniswaps router contract to be vulnerable to a re-entrancy exploit, allowing attackers to move anyone’s tokens if approved to the Uniswap’s contact. Use @Revoke Cash in order to revoke any vulnerable approvals.” Users across social media spaces have criticized the incident based on the fact that a blockchain security firm’s account was compromised and a phishing link shared.
“Disregard this post, apparently Vitalik has been hacked. He is working on restoring access,” his father wrote in a tweet. This is not the first time CertiK has been the victim of a social platform compromise as hackers continue to target popular accounts to post phishing links. In December, CertiK’s website posted a Discord link with phishing links belonging to a fake server. On Jan 4, it was reported that the CEO of Polychain’s X account was hacked in a phishing scam with the team warning users not to engage. At press time, the phishing links have been deleted from the account but it reaches over 41,000 users. “In celebration of the New Year, They have decided to start the $PCHAIN phase 1 distribution early! What are you waiting for? Get your share before it’s too late! Register below to participate.” CertiK recently released a new report on cryptocurrency hacks highlighting a drop in 2023 but revealed that over $1.8 billion was lost from 751 security breaches. According to the release, Q3 2023 witnessed the most losses resulting in over $686 million stolen from 183 incidents followed by November. While the number of scams plunged, the crypto community is still worried about the number of phishing incidents recorded in the past months calling on both users and platforms to be more vigilant. Blockchain security firm, Scam Sniffer reported that over 295 million was stolen from 320,000 users in the last 12 months. [Source] Meet Ju Ki-young, a South Korean tech entrepreneur who co-founded the blockchain analysis firm CryptoQuant. About Ju: Born in 1992, Ju, an alumnus of Pohang University of Science and Technology, co-founded CryptoQuant with fellow alumni in April 2019. Before becoming its CEO and entering the blockchain sphere, he was a software engineer who offered analyses for businesses. What CryptoQuant does: CryptoQuant, which South Korea's Chosun Daily dubs as the "Bloomberg of Crypto," provides on-chain and market data gathered from blockchain and major cryptocurrency exchange platforms. The company keeps track of every transaction that occurs in the market. Making a name: Using on-chain data analysis, CryptoQuant says it was the first to notice the impending crash of the Terra-Luna cryptocurrency in May 2022 and the potential bankruptcy of FTX months after. Trending on NextShark: Doctors remove 300 kidney stones from woman who drank bubble tea instead of water Ju raised the red flag in an X post, pointing out how Terraform Labs' nonprofit, Luna Foundation Guard, transferred around 37,000 Bitcoins (approximately $1.59 billion in today's exchange) to Gemini, a cryptocurrency exchange. A few days after making the post, Terraform Labs' Luna, the sister token of stablecoin TerraUSD, crashed to virtually $0. With its success, CryptoQuant signed a partnership deal with the Chicago Mercantile Exchange (CME Group), the world’s largest derivatives and options exchange, as the latter’s on-chain data provider in July of the same year.

In 2019, the company used its expertise to uncover the e-wallets of those involved in the “Nth Room” scandal, leading to the arrest of masterminds Cho Ju-bin, Moon Hyung-wook and others.

The UN refugee agency is working on decentralized digital ID utilizing blockchain to protect the identity of people crossing borders is risky situations. UNHCR Division of Financial and Administrative Management Treasurer Carmen Hett said during a panel discussion at Decentral House in Switzerland at the close of 2023. The panel also included representatives of the World Trade Organization and International Telecommunication Union, and focussed largely on how to build support and acceptance for the use of blockchain within agencies that are operationally conservative. There are 114 million displaced people around the world, according to Hett, and the UNHCR’s challenge is to deliver the assistance they need and support their financial inclusion, based on accurate information. Aid is deposited in refugees’ digital wallets to deliver them some degree of control over how the funds are spent. Hett admits some skepticism among UNHCR staff about the use of blockchain, but says with the first use case delivered successfully, the project is now scaling up. The use of blockchain for aid payments means that UNHCR can provide aid “within literally minutes,” Hett says, and does so “at zero cost.” This promise allowed her to challenge skeptics within her organization to come up with a reason why blockchain could not be used. Delivering aid in the form of USDC stablecoins deposited in a digital wallet also builds the digital and financial literacy of refugees, Hett argues. That is the model used to deliver aid directly to people fleeing the Russia’s war against Ukraine, using biometrics to verify the identity of recipients. The project won the “Best Impact Project Award” at Paris Blockchain Week 2023. The UNHCR’s next use cases for blockchain is fundraising through a staking pool and the production of NFTs to raise awareness of the agency’s work. Digital identity not only goes along with the digital wallet, but also carries particular risk for refugees. For this reason, Hett says, UNHCR is considering how to use zero-knowledge proofs (ZKPs) to protect refugee’s data. For the benefits of technical tools like ZKP to be realized, however, more regulatory work is needed, Hett says. blockchain  | decentralized ID  | digital identity  | refugee registration  | UNHCR  | Zero Knowledge | ||||||||
