Overview of Sound Blockchain Protocol
Q7: Can an attacker use power analysis instead?
Yes, power analysis (by measuring the current drawn from the laptop’s
DC power supply) is another way to perform our low-bandwidth attack.This too is detailed in our follow-up paper, “Get
Your Hands Off My Laptop: Physical Side-Channel Key-Extraction Attacks
Is Bitcoin a bubble?
Hard to say.
Can NFTs Crack Royalties And Give More Value To Artists?
Music is part of my monthly budget.Pre-pandemic this included live music, some vinyls on the side, not to mention subscriptions to the streaming platforms.During the pandemic it’s been Bandcamp Fridays, NFTs, and monthly donations through Patreon to support the venues and communities that are the soul of New York City — that comprise my own soul.Music was a comfort in an otherwise difficult year; it’s a cruel irony that artists have captured so little of the value they create.
What are altcoins?
Since Bitcoin launched in 2008, thousands of other cryptocurrencies and altcoins (“alternative coins”) have emerged.
Is blockchain scalable?
For a blockchain to work, lots of participants need to hold up-to-date copies.This means that the same database is held by thousands of nodes.This is fairly inefficient.
Are you ready for blockchain?
That’s the blockchain landscape in a nutshell.Does all this mean that IT will soon be replacing and managing today’s compute, storage, and communications technologies with blockchain-based technologies? Probably not right away.
How did Covid-19 impact Bitcoin?
The global market crash in March triggered by Covid-19 has also led to the prices of crypto assets to drop in one of the sharpest declines in history.The price of Bitcoin fell by nearly 50% in the span of 24 hours.
How Bad Is Blockchain Scalability Today?
In order to scale a blockchain, increasing the block size or decreasing the block time by reducing the hash complexity is not enough.With either method, the ability to scale reaches a ceiling before it can hit the transactions necessary to compete with businesses like Visa, which “handles an average of 150 million transactions every day” or around 1,736 transactions per second (TPS).
What is blockchain?
So far, we’ve discussed two types of ledgers.
How does the protocol work?
The Ampleforth protocol translates price-volatility into supply-volatility.
Don’t other NFTs pay out royalties?
Not necessarily.Right now, most NFTs are minted as ERC-721 tokens, which means that when an artist initially sells their work to a buyer, that will be the only time they receive money for the sale.If the buyer then flips it on a secondary market like OpenSea for 5 times the price, the original artist sees none of that.
Cool, but how does this all work with traditional Performing Rights Organizations?
In the year 2021, enterprising artists have already begun tokenizing audio files and selling them to fans as NFTs.We are also getting closer to a more universal royalties standard for these NFTs.
Q14: Why software countermeasures? Isn’t it the hardware’s
responsibility to avoid physical leakage?
It is tempting to enforce proper layering, and decree that preventing
physical leakage is the responsibility of the physical hardware.Unfortunately, such low-level leakage prevention is often impractical
due to the very bad cost vs.security tradeoff: (1) any leakage remnants
can often be amplified by suitable manipulation at the higher levels, as
we indeed do in our chosen-ciphertext attack; (2) low-level mechanisms
try to protect all computation, even though most of it is insensitive or
does not induce easily-exploitable leakage; and (3) leakage is often an
inevitable side effect of essential performance-enhancing mechanisms
(e.g., consider cache attacks).Application-layer, algorithm-specific mitigation, in contrast, prevent
the (inevitably) leaked signal from bearing any useful information.It
is often cheap and effective, and most cryptographic software (including
GnuPG and libgcrypt) already includes various sorts of mitigation, both
through explicit code and through choice of algorithms.In fact, the
side-channel resistance of software implementations is nowadays a major
concern in the choice of cryptographic primitives, and was an explicit
evaluation criterion in NIST’s AES and SHA-3 competitions.
Is blockchain economical?
One of the keys to blockchain technology being viable in the long-run is making sure that transactions like Alice and Bob’s can be executed with minimal fees.Fees are important because they incentivize miners to add your transactions to the blockchain in a timely manner — but high fees make it harder to convince potential users to get on board.
Is blockchain safe?
A publicly-accessible ledger may seem like a breach of privacy.However, its public nature allows a blockchain money transfer to be monitored by all participating parties (nodes), providing a platform of trust that is tamper-proof and immutable.
How secure is Bitcoin?
You may have noticed a key difference between the above example and Bitcoin.Specifically, Alice’s and Bob’s ledger only allows “trusted friends” to participate.In contrast, Bitcoin is entirely public, and anyone can participate.
Where are cryptocurrencies illegal?
Bitcoin and other forms of cryptocurrencies are prohibited in Algeria, Egypt, Morocco, Bolivia, Ecuador, Nepal, Pakistan, Indonesia, and Vietnam.
Is Blockchain Secure?
Blockchain technology accounts for the issues of security and trust in several ways.First, new blocks are always stored linearly and chronologically.That is, they are always added to the “end” of the blockchain.If you take a look at Bitcoin’s blockchain, you’ll see that each block has a position on the chain, called a “height.” As of November 2020, the block’s height had reached 656,197 blocks so far.
How was blockchain created?
Blockchain technology found its origin in cryptocurrencies like Bitcoin.It enabled the exchange of currency, recording each blockchain money transfer into a publicly-accessible digital ledger.
What are stablecoins?
Stablecoins are virtual currencies pegged to an asset such as fiat money or gold.The most popular stablecoins are pegged to the dollar, with the value of one unit being close to $1.Most stablecoins maintain this price stability through a reserve of fiat, other cryptos, or precious metals held as collateral.
What do you need to send money using blockchain?
In order to initiate a transaction, blockchain users must create a wallet, which works as an address, and a private key.These two things represent a user’s identity within the blockchain.Unlike the private key, the wallet is public.They work together to maintain security and accountability.
Q11: Is there a realistic way to perform a chosen-ciphertext attack on
To apply the attack to GnuPG, we found a way to cause GnuPG to
automatically decrypt ciphertexts chosen by the attacker.The idea is to
use encrypted e-mail messages following the OpenPGP
protocols.For example, Enigmail
(a popular plugin to the Thunderbird e-mail client) automatically
decrypts incoming e-mail (for notification purposes) using GnuPG.An
attacker can e-mail suitably-crafted messages to the victims, wait until
they reach the target computer, and observe the acoustic signature of
their decryption (as shown above), thereby closing the adaptive attack
So, what is Ethereum?
A smart contract allowed Alice and Bob to build a very small decentralized application.
How does blockchain work?
In order to send data, blockchain uses a distributed ledger and hash function.What does this mean? A transaction is converted into a code, which is added to a ledger and shared with multiple fact-checking computers.Let’s break it down.
What is a smart contract?
To illustrate a smart contract, let’s say Alice and Bob enter into a bet.
What are initial coin offerings?
We’ve now discussed Bitcoin and Ethereum.Both blockchains use a “token” that provides utility.Bitcoin uses bitcoin, while Ethereum uses ether.

Is blockchain anonymous?
In the early days of Bitcoin, blockchain technology — like many nascent technologies — was popularly associated with illicit activities.
Why are ICOs so controversial?
Initial coin offerings could represent a big shift in how companies raise money and/or incentivize various stakeholders (e.g., developers, investors, users).
What is halving?
Halving reduces the amount of bitcoin awarded per block to miners by half.Also called “the halvening,” it occurs after every 210,000 blocks mined in the Bitcoin blockchain — about every 4 years.Written in the original protocol, halvings are used to limit the supply of new bitcoin and help control the cryptocurrency’s value.
What are utility tokens?
Teams holding ICOs are adamant that they do not represent securities offerings and instead market their coins or tokens as part of an entirely new asset class altogether.
Looking for the Open Peer Review Reports?
They can now be found at the top of the panel on the right, linked from the box entitled Open Peer Review.Choose the reviewer report you wish to read and click the ‘read’ link.You can also read all the peer review reports by downloading the PDF.
Where else might blockchain make sense?
The short answer: broadly, but in specific instances.
What is Bitcoin?
Bitcoin is, according to its whitepaper, a “peer-to-peer electronic cash system” that “allow[s] for online payments to be sent directly from one party to another without going through a financial institution.
What is Bitcoin Cash?
Bitcoin Cash is not the same thing as Bitcoin, although it shares much of its history with that protocol.
What is Ethereum?
We asked earlier what other applications could be built with blockchain technology.
Q20: What is the purpose of your research?
People entrust their most private information to computers, under the
assumption that their computers will keep their secrets.Our goal is to
discover when this assumption is dangerously false: to understand how
information may be leaking in unexpected ways that can be used
nefariously.We then seek ways to build software and hardware that will
better protect the users.In this case, for example, we worked with the
developers of the vulnerable software to change the mathematical
operations so that the emitted sound will not reveal the secret key.
How is Blockchain Used?
As we now know, blocks on Bitcoin’s blockchain store data about monetary transactions.But it turns out that blockchain is actually a reliable way of storing data about other types of transactions, as well.
What are the major issues with blockchain technology?
Blockchain technology is really good at some things and absolutely awful at others.
Where does distributed ledger technology make sense?
Let’s back up for a moment.
What is Blockchain?
Blockchain technology offers a way for untrusted parties to reach consensus on a common digital history.A common digital history is important because digital assets and transactions are in theory easily faked and/or duplicated.Blockchain technology solves this problem without using a trusted intermediary.
What does Euler’s Phi Function Have to Do with Music?
Two weeks ago, Treum, a ConsenSys Mesh portfolio company, created a project called EulerBeats, which is 27 algorithmically generated art and music NFTs.The name is a nod to the 18th century mathematician’s totient function phi, and if theoretical mathematics isn’t your thing, think of it as a function for pricing every subsequent print.As the number of prints in circulation grows for a particular original, the price of issuing its next print increases at an exponential rate.These NFTs use a modification of the ERC-721, called the ERC-1155.This means that with every future sale, the original LP holder gets a royalty of 8%, with another 2% going to Treum.In two weeks, the smart contracts governing the unique LPs paid out 912 ETH ($1,429,012) in royalties, automatically.
What is Blockchain?
Blockchain seems complicated, and it definitely can be, but its core concept is really quite simple.A blockchain is a type of database.To be able to understand blockchain, it helps to first understand what a database actually is.
Why is Bitcoin Cash controversial?
Supporters of Bitcoin Cash and Bitcoin commonly spar over the functionality of the two coins.
Where can you send money?
Blockchain money transfers can be sent and received in any country that allows the technology to exist.However, with Veem, blockchain money transfers can be sent to Mexico, Brazil, and the Philippines.
Is the Ethereum blockchain protocol for real?
Ethereum founder Vitalik Buterin
Over the weekend, an “attacker” commandeered 3,641,694 ether, a virtual currency worth the equivalent of US$60 million, from the DAO, which is short for “distributed autonomous organization”, a decentralized venture capital fund built on the Ethereum blockchain protocol which recently raised the largest ever amount for a crowdfunding campaign, US$117 million.If more than half a dozen words in that sentence made any sense to you, including “and” and “the”, welcome to the brave new world of the blockchain, in which nothing is real except for the promise of a better tomorrow.As Ethereum founder Vitalik Buterin said a couple weeks ago at a presentation in Singapore, “If the concept of Uber without the Uber, Facebook sign-in without the Facebook, banking without banks, excites you, this is the technology for you.”
For a certain kind of person, that proposition sounds very appealing indeed, even if they struggle to understand how it would actually work in practice.The stakes are about as high as they can be.Either this is the kind of technology that completely transforms how we all interact with each other, the way the internet did in the 1990s, or it’s a virtually meaningless exercise enacted entirely in cyberspace.Regarding this recent hack, Buterin has assured DAO investors that “even if no action is taken, the attacker will not be able to withdraw any ether at least for another ~27 days (the creation window for the child DAO).This is an issue that affects the DAO specifically; Ethereum itself is perfectly safe.”
The DAO is a leaderless venture capital fund, with no central authority doling out the money.Meanwhile, “The Attacker” (that’s the name he’s chosen) insists that he obtained the virtual money legitimately, by exploiting a vulnerability in the code, and that he furthermore intends to pursue “legal action against any accomplices of illegitimate theft, freezing, or seizure of my legitimate ether”.How an actual court in our physical reality will adjudicate the “seizure of my legitimate ether” is anyone’s guess.One DAO investor, Elain Wu, is not okay with Buterin’s proposed intervention, explaining in a blog post that the hacker who exploited the network has simply exposed a vulnerability that needs to be fixed.“I prefer that the ‘hacker’ keep whatever ether I lost.The great thing about smart contracts is the predictable risk allocation.I signed up for the risk of losing my ether.I did not sign up for third-party adjudication,” writes Wu, adding, “Blockchain contracts are not about adjudication by vote; we already have a very good solution for that in the modern court system.They’re about giving two parties the ability to trust a commitment.I want the rights and responsibilities that I signed up for.
What Is Blockchain Technology?
Few people understand what it is, but Wall Street banks, IT organizations, and consultants are buzzing about blockchain technology.It’s hard to remove blockchain from Bitcoin, so we’ll start with Bitcoin as we work to understand this technology’s potential.
Q19: Aren’t sensitive devices protected by
Interestingly, many of the physical side-channel countermeasures used
in highly sensitive applications, such as air gaps, Faraday cages, and
power supply filters, provide no protection against acoustic leakage.In
particular, Faraday cages containing computers require ventilation,
which is typically provided by means of vents covered with perforated
sheet metal or metal honeycomb (see Q1 above).These are very effective at attenuating compromising electromagnetic
radiation (“TEMPEST”), but are nearly transparent to sound.
What's Next for Blockchain?
First proposed as a research project in 1991,?? blockchain is comfortably settling into its late twenties.Like most millennials its age, blockchain has seen its fair share of public scrutiny over the last two decades, with businesses around the world speculating about what the technology is capable of and where it’s headed in the years to come.
What do we mean by Stable Contracts?
Let’s go through a simple example.Imagine Evan and Micah enter into a bet: “If the Lakers make it to the 2022 NBA conference finals, Micah will pay Evan 10 coins.Otherwise, Evan will pay Micah 10 coins.
What is Litecoin?
Another altcoin that’s gradually entered the popular vernacular is Litecoin.It was invented in 2011 by former Google engineer Charlie Lee to act as a cheaper and faster version of Bitcoin.It’s a lower-priced cryptocurrency that’s almost identical to Bitcoin — there are just a few minor tweaks that are intended to make it a more fitting tool for daily commerce.
What is DeFi?
Decentralized finance (DeFi) is an ecosystem of smart contracts that allows participants to offer and access financial services in a peer-to-peer format, without relying on traditional intermediaries like banks, credit unions, or brokerages.
Everybody in the industry agrees that knowing the name of the songwriters, players, engineers, and producers on a specific record is essential knowledge.As well, the name of the publisher and what label owns the sound recording are required for transacting business.To eliminate friction, reduce costs, expedite payments, and enable the usage and licensing of music to happen seamlessly, accurate information needs to be shared and automatically updated.
Where are cryptocurrencies legal?
In other countries, bitcoin and other digital currencies may be legal, but are restricted from banks.Countries in this category include Canada, China, Columbia, Saudi Arabia, Jordan, Iran, Bangladesh, India, Taiwan, and Cambodia.
Why does Ethereum matter?
In August 2016, then-Union Square Ventures investor Joel Monegro published a blog post entitled “Fat Protocols.
Why is Bitcoin Cash valuable?
Controversy aside, is the value proposition of Bitcoin Cash a sound one? Like the crypto sector at large, the price is highly volatile.
Why is the price of Ethereum so high?
Ethereum’s blockchain allows for the creation of a decentralized supercomputer.This supercomputer is the first one of its kind.
