    1. automate transactions

      For example, think about paying your monthly bills. Instead of writing checks and mailing them, you can set up automatic payments through your bank's website. The bank's computer system will send the money to the right places at the right times without you needing to do it every month.

    1. Blockchains and distributed ledgers also use SMR, in which casethe chain of blocks (and the transactions therein) constitutes theevent log, the ledger (e.g. the balance of every account) is the result-ing state, and smart contracts or the network’s built-in transactionprocessing logic are the state transition function [66].

    12. BBH

      Every Saturday I send tokes to people that own BBH. Here is the break down.

      If you own 10 or more BBH up to 4,999 you get dripped Hive(swap.hive).

      If you own 5,000 or more BBH up to 9,999 you get dripped swap.hive and Alive Tokens.

      If you own 10,000 or more BBH you get dripped swap.hive, Alive and $LEO tokens.

      All just for owning BBH.

      You can get BBH two ways, you can buy it of TribalDex or you can have it tipped to you.

      Here is the tipping part:

      In a 24 hour period, reset at new day UTC. There are currently four levels of tipping.

      Level 1 = 1000 BBH holdings = 1 tip per day you can send Level 2 = 5000 BBH holdings = 5 tip per day you can send Level 3 = 20000 BBH holdings = 20 tip per day you can send Level 4 = 50000 BBH holdings = 50 tip per day you can send

      You don't have to stake, just hold. The tip does not come from your holdings but from BBH itself.

      As BBH grows, so will the rewards.

    1. all the data about how people how much 00:30:19 people ask for the values become creates a ranking of values according to the culture to the people so if you're from korea from taiwan from uk 00:30:32 from from italy uh it's different and so this is a periodic table of values where the values are organized in a hierarchy based on how people collect them 00:30:44 and and and then the values become of course words and this is a calligraphy of values that result from the process of using eeg
      • values from different culture are displayed via eeg

      -Comment - this display would make an excellent BEing journey to explore perspectival knowing, situatedness and the misunderstandings that emerge from different ways of seeing the world, different meanings attached to the same words, and different saliencies and priorities

    2. in korea during uh idea 2019 and at the end of the process what you 00:29:00 have designed the 3d model uh you you get you get a qr code and you cannot have it on a wallet and it's registered on the blockchain and so you can start trading 00:29:12 so just imagine that you trade happiness you trade love anarchy art autonomy peace purity you trade them as values becoming value 00:29:24 having a value and so people can decide by battering swapping them if you want if you want peace and love for power

      Reddit blockchain vault for avatars

      First time a service I've used has encouraged a blockchain vault for any reason. Here they're giving away a free avatar which I'm supposed to save in my vault, so obviously it's very valuable. (meh!)

    1. and though he is right that blockchain currencies can “enable the real-life future by indelibly recording the past,” the question remains who exactly will use those powerful tools to create what kind of culture with which sorts of values.


    1. One-click Login with Blockchain: A MetaMask TutorialOnline users are becoming increasingly resistant to traditional email/password registration processes. One-click social logins via Facebook, Google, or GitHub are better, but they come with data privacy trade-offs. This article introduces a one-click, cryptographically-secure login flow using MetaMask, with all data stored on the app’s own back-end.
    1. It included a shared public ledger with crypto-provable integrity that recorded all this stuff. But no blockchain because we just couldn’t convince ourselves that the real world wanted zero-trust; so there was a transaction manager you had to trust. Dear Reader: I think that at some point, in a civilization, there has to be trust. I think that’s maybe the main reason we have civilizations. Call me crazy.

      Trust is an achievement not a burden.

    1. What Is a Blockchain Oracle? A blockchain oracle is a secure piece of middleware that facilitates communication between blockchains and any off-chain system, including data providers, web APIs, enterprise backends, cloud providers, IoT devices, e-signatures, payment systems, other blockchains, and more. Oracles take on several key functions: Listen – monitor the blockchain network to check for any incoming user or smart contract requests for off-chain data. Extract – fetch data from one or multiple external systems such as off-chain APIs hosted on third-party web servers. Format – format data retrieved from external APIs into a blockchain readable format (input) and/or making blockchain data compatible with an external API (output). Validate – generate a cryptographic proof attesting to the performance of an oracle service using any combination of data signing, blockchain transaction signing, TLS signatures, Trusted Execution Environment (TEE) attestations, or zero-knowledge proofs. Compute – perform some type of secure off-chain computation for the smart contract, such as calculating a median from multiple oracle submissions or generating a verifiable random number for a gaming application. Broadcast – sign and broadcast a transaction on the blockchain in order to send data and any corresponding proof on-chain for consumption by the smart contract. Output (optional) –  send data to an external system upon the execution of a smart contract, such as relaying payment instructions to a traditional payment network or triggering actions from a cyber-physical system.

      Seems related to the paradox of information systems. Add to Anki deck

    1. What would a secure Federated PMK / archive network backed by a minimal blockchain look like?

      Possibly like Holochain (which is distinct from the blockchain architecture). Blockchain only seems helpful if you need all of the following: - a database - immutability - distributed data - decentralized & totally trustless - append only - cryptographically secure assurance

      Confer Brandon Enright's provocative talk "Blockchain is Bullshit" for an elaboration of these features. The first 10 or so minutes is mostly uninsightful trolling, so the link takes one to his argument about the key features of blockchain.

      AFAICT, Holochain eases the feature of "decentralized", although Laurie Voss suggests that it's better to think of Bitcoin & Ethereum as "distributed" (in both the structure & control).

      In Voss' taxonomy, I suspect that Holochain's structure would be "distributed" (ie, "No total point of failure, all nodes work on shared goal") and control would be "federated" (ie, "Limited set of shared rules, multiple overlapping/conflicting rules below")

    1. Ideally, the green and digital transitions reinforce each other. For example, distributed ledger technology, which underlies blockchain and thus cryptocurrencies, can be used in material tracing, aiding the circular economy by better maintenance and recycling.

    1. We finish with a com-parative analysis of these blockchain technologies,in terms of their relative vulnerability to quantumattacks.

      We expect a comparative analysis of various BCh technologies, in terms of their relative vulnerability to quantum attacks.

    2. Given the strong coupling between data andcryptosystems in blockchains, the potential vulner-ability of these cryptosystems to quantum attacks,the likely introduction of capable quantum com-puters in the mid-term future—not to mention theusual high monetary value of the assets secured byblockchains—it is important to more deeply under-stand their current level of vulnerability.

      Author states its motivation: - strong coupling between data and cryptosystems in BCh - the cryptosystems potential vulnerability to quantum computers - the likely introduction of quantum computers in the mid-term future - also the high monetary value of the assets secured plus momentum of BCh.

    3. vulnerable toadvances in quantum technology

      the major threat: quantum technology

    4. n blockchainsthe protected resources cannot easily be decoupledfrom the encryption system being used


      In BCh, data decoupling from encryption system is not easy. How much difficult it is?

    1. Time constraints

      timestamps guarantee the coherences of the state of contract after the execution.

      Exposes to attack, because a miner can choose the timestamp with a certain degree of arbitrariness.

    2. Generating randomness.

      EVM execution is deterministic. How to account for randomness?

      Pesudo random generator, probability distribution.

    3. Unpredictable state

      state of the contract it determined by the value of its fields and balance.

      sequentiality -->contract's state is not guaranteed

    4. Taxonomy of vulnerabilities in Ethereum smart contracts

      Three levels: language, ecosystem and infrastructure.

    1. blockchain's consensus model

      blockchain uses method to batch transactions into block. Establishing which node can submit a block to the chain is the blockchain consensus model or consensus algorithm.

    2. use a more elaborate method to select transactions and choose between conflicting state transition.

    1. Of course letting arbitrary code potentially run forever wouldn’t work.  So instead any program is run for only a limited number of instructions until it either completes or is terminated. The measure of the amount of compute is called “gas”, with various instructions and operations costing a different amount of gas to process.  The total cost of a transaction is the amount of gas consumed times the gas price.

      Definition of "gas" on the blockchain

    1. These programs are called smart contracts, which is misleading because look, here's an example of a smart contract. There's no legal language in there. It doesn't function as a legal document.

    1. Open educational resources (OERs) are fungible functional units used in education by both educators and students

      OERs on Ethereum

    1. If we don't create good large-scale aggregates of social data, then we risk ceding market share to opaque and centralized social credit scores instead.

      Vitalik argues that if we don't create good decentralized social credit score systems, that vacuum will be filled by centralized alternatives.

    2. This is equivalent to the famous double-spend problem in designing decentralized currencies, except instead of the goal being to prevent a previous owner of a coin from being able to send it again, here the goal is to prevent the previous key controlling an account from being able to change the key. Just like creating a decentralized currency, doing account management in a decentralized way requires something like a blockchain. A blockchain can timestamp the key change messages, providing common knowledge over whether B or C came first.

      Decentralized account management may also run into a problem analogous to the double spend problem. Someone with key A signs a message they are now using key B, and an attacker gets a hold of that key and signs a message they are using key C. An observer has no way of knowing whether the message about B or C happened first.

    1. Additional NFT certificates of completion are being created for students who completed Duke Engineering’s blockchain course sequence in earlier sessions

      Makes sense to credential legacy earners; as long as the competencies didn't change, it seems inequitable to deny previous learners the same recognition as new learners.

    1. We can program a blockchain to record virtually everything or anything of value and importance, not only payments and profits, but birth and death certificates, marriage licenses, deeds, titles of ownership, educational degrees

      How can we store physical assets on the blockchain?

    1. And how about growing social inequality? Through the blockchain, we can gofrom redistributing wealth to distributing value and opportunity fairly

      How can this be accomplished, specially for people who don't have access to the internet? Will you still need an intermediary, possibly Non-profits who will be able to have better transparency for how the assets are used to accomplish the mission?

    1. The second reason might support positive change. The existence of tokens and decentralization means that it’s possible to build resilient open source communities where early contributors and supporters benefit handsomely over time. No one owns these communities, and we can hope that these communities will work hard to serve themselves and their users, not the capital markets or other short-term players.

      Capitalism's subject is Capital, not the bourgeoisie or an owner class. "Open source communities" are still corporations.

    2. And that’s the first reason that the blockchain matters—because there’s a chance that it might lead to more open, resilient, market-focused networks and databases. It’s only a chance, though, because all the hype around the tokens sometimes makes it seem more likely that financial operators will simply seek to manipulate unregulated markets for their own benefit.

      There's no chance. Blockchains by principle benefit corporations in the long run.

    3. Okay, so what’s the blockchain? It’s a database. Unlike most databases, it’s not controlled by one entity and it’s not easily rewritten. Instead, it’s a ledger, a permanent, examinable, public database. One can use it to record transactions of various sorts. It would be a really good way to keep track of property records, for example. Instead, we have title insurance, unsearchable folders of deeds in City Hall and often dusty tax records.

      This wrongly assumes that

      • Permanent records are always desirable
      • Accountability undermines corporations

    1. It will take time for the idea of decentralized trust through computation to become a part of mainstream consciousness, and until then, the idea creates cognitive dissonance for those accustomed to centralized trust systems. With thousands of years of practical use, centralized systems of trust are accepted unconditionally and without much thought as the only model of trust.


    1. We call blockchain the Trust Protocol. It's for people who don't know each other and with no reason to trust each other. Yet these people can still do business together on a blockchain, because they can trust the blockchain protocols. These protocols preserve the integrity of their transaction.

      Blockchain in a nutshell. Easy to understand.

    1. The prototype elaborated by P2P Models is called “Open.Smart”. Basically, the prototype is designed as a transparent database which serves to collect and order Smart member data. This data is supplemented by other records and documents required for subscription and is saved and encrypted in the blockchain. Open.Smart is an external app that relies on a digital wallet called Metamask that makes it possible to interact with the Smart platform (Figure 3 illustrates the beta version of Open.Smart)

      But ... why have it on the blockchain vs a normal database?

    1. Partisans of the blockchain might say that it’s okay if these types of centralized platforms emerge, because the state itself is available on the blockchain, so if these platforms misbehave clients can simply move elsewhere. However, I would suggest that this is a very simplistic view of the dynamics that make platforms what they are.

      Indeed ...

      However, I would suggest that this is a very simplistic view of the dynamics that make platforms what they are.

    2. MetaMask doesn’t actually do much, it’s just a view onto data provided by these centralized APIs. This isn’t a problem specific to MetaMask – what other option do they have? Rainbow, etc are set up in exactly the same way. (Interestingly, Rainbow has their own data for the social features they’re building into their wallet – social graph, showcases, etc – and have chosen to build all of that on top of Firebase instead of the blockchain.) All this means that if your NFT is removed from OpenSea, it also disappears from your wallet. It doesn’t functionally matter that my NFT is indelibly on the blockchain somewhere, because the wallet (and increasingly everything else in the ecosystem) is just using the OpenSea API to display NFTs, which began returning 304 No Content for the query of NFTs owned by my address!

      Indeed ...

    1. Enter the blockchain, the first native digital medium for peer-to-peer valueexchange. Its protocol establishes the rules—in the form of globally distributedcomputations and heavy duty encryption—that ensure the integrity of the datatraded among billions of devices without going through a trusted third party.

      Yes I have always pondered the extent, need and cons of having third parties with monopolies on our value exchange and how trust can be established without them. Blockchain is so powerful in this regard.

    1. Most of the descriptions I’ve seen focus on mechanisms - block chains, smart contracts, tokens, etc - but I would argue those are implementation details and some are much more likely to succeed than others. (E.g. I think using private keys for authentication/authorization is obviously better if you can get over the UX hump - SSH has shown us that for decades.)

      Most descriptions of Web3 focus on mechanisms — blockchains, smart contracts, etc — but those are implementation details.

    1. This Internet of Everything needs a Ledger of Everything. Business, commerce, and the economy need a Digital Reckoning.

      Internet of Everything -- Ledger of Everything

    1. So the smaller the smart contract the better then.

    2. So this must mean that solidity code is very lean. Importing packages takes up memory and since you're only borrowing from the miner this would be a bad idea.

      Does this mean I'll have to recreate everything again or is it the wrong approach if you have to do so?

    1. Maybe it’s time to dig into the non-blockchain smart contract idea that’s been floating around for a while. Drop the PoW and transaction fees, but maintain the trustless verification and open data/code

      There was publictimestamp,org. It was a blockchain but it was open, no PoW/fees. It was centralized but they asked everyone to help with attestation.

    1. Centralization vs decentralizationIn the table below, we list some of the broad-strokes advantages and disadvantages of centralized and decentralized digital networks.Centralized SystemsDecentralized SystemsLow network diameter (all participants are connected to a central authority); information propagates quickly, as propagation is handled by a central authority with lots of computational resources.The furthest participants on the network may potentially be many edges away from each other. Information broadcast from one side of the network may take a long time to reach the other side.Usually higher performance (higher throughput, fewer total computational resources expended) and easier to implement.Usually lower performance (lower throughput, more total computational resources expended) and more complex to implement.In the event of conflicting data, resolution is clear and easy: the ultimate source of truth is the central authority.A protocol (often complex) is needed for dispute resolution, if peers make conflicting claims about the state of data which participants are meant to be synchronized on.Single point of failure: malicious actors may be able to take down the network by targeting the central authority.No single point of failure: network can still function even if a large proportion of participants are attacked/taken out.Coordination among network participants is much easier, and is handled by a central authority. Central authority can compel network participants to adopt upgrades, protocol updates, etc., with very little friction.Coordination is often difficult, as no single agent has the final say in network-level decisions, protocol upgrades, etc. In the worst case, network is prone to fracturing when there are disagreements about protocol changes.Central authority can censor data, potentially cutting off parts of the network from interacting with the rest of the network.Censorship is much harder, as information has many ways to propagate across the network.Participation in the network is controlled by the central authority.Anyone can participate in the network; there are no “gatekeepers.” Ideally, the cost of participation is very low.

    1. A blockchain system has no ability to regular "the market" in the sense of people's general ability to freely make transactions. But what it can do is regulate and structure (or even create) specific markets, setting up patterns of specific behaviors whose incentives are ultimately set and guided by institutions that have anti-collusion guardrails built in, and can resist pressure from economic actors.
    2. There is a large body of intellectual work that criticizes a bubble of concepts that they refer to as "economization", "neoliberalism" and similar terms, arguing that they corrode democratic political values and leave many people's needs unmet as a result. The world of cryptocurrency is very economic (lots of tokens flying around everywhere, with lots of functions being assigned to those tokens), very neo (the space is 12 years old!) and very liberal (freedom and voluntary participation are core to the whole thing). Do these critiques also apply to blockchain systems? If so, what conclusions should we draw, and how could blockchain systems be designed to account for these critiques? Nathan's answer: more hybrid approaches combining ideas from both economics and politics. But what will it actually take to achieve that, and will it give the results that we want?

    1. Active Indexers, Curators and Delegators can earn income from the network proportional to the amount of work they perform and their GRT stake.
    2. Curators are subgraph developers, data consumers or community members who signal to Indexers which APIs should be indexed by The Graph Network. Curators deposit GRT into a bonding curve to signal on a specific subgraph and earn a portion of query fees for the subgraphs they signal on; incentivizing the highest quality data sources. Curators will curate on subgraphs and deposit GRT via the Graph Explorer dApp. Because this occurs on a bonding curve, that means that the earlier you signal on a subgraph, the greater share of the query fees you earn on that subgraph for a given amount of GRT deposited. This also means that when you go to withdraw, you could end up with more or less GRT than you started with.

      cryptoeconomics still amazes me, how everything can be an opportunity for 'investment'

    1. Liquidity pools are pools of tokens that are locked in a smart contract. By offering liquidity, they guarantee trading, and because of this, they are widely used by decentralized exchanges.
    1. Then there are tokens. Tokens by definition do not run on their own blockchain, unlike a coin. They have been added to an already existing blockchain. Tokens can have the same functionality as a coin, although this is not common.Tokens that are created on the Ethereum network are typically ERC-20 tokens.
    2. Developers can program applications that can create, store and manage digital assets, also known as tokens, on the blockchain. For this to work, smart contracts and decentralized applications (DApps) are written and built. The expiration of these contracts and agreements is automatically enforced if the blockchain receives the correct data. You can make complex, irreversible agreements without the need for an intermediary.

    1. Though things are improving, the fact remains that no Blockchain model is truly energy efficient, so if you’re in doubt as to whether you need it and are concerned about CO2 emissions, you should proceed with caution. In some ways, the problem of the Blockchain is that it hit the public imagination - and that of app developers and entrepreneurs - long before the technology was fully mature (it definitely still isn’t) and many of these scalability and energy-consumption problems have yet to be ironed out. 
    1. The high costs of implementing a TTP come about mainly because traditional security solutions, which must be invoked where the protocol itself leaves off, involve high personnel costs. For more information on the necessity and security benefits of these traditional security solutions, especially personnel controls, when implementing TTP organizations, see this author's essay on group controls. The risks and costs borne by protocol users also come to be dominated by the unreliability of the TTP – the DNS and certificate authorities being two quite commom sources of unreliability and frustration with the Internet and PKIs respectively.

      The high costs of TTPs have to do with the high personnel costs that are involved in the centralized solutions.

    1. So, what problem is blockchain solving for identity if PII is not being stored on the ledger? The short answer is that blockchain provides a transparent, immutable, reliable and auditable way to address the seamless and secure exchange of cryptographic keys. To better understand this position, let us explore some foundational concepts.

      What problem is blockchain solving in the SSI stack?

      It is an immutable (often permissionless) and auditable way to address the seamless and secure exchange of cryptographic keys.

    1. blockchain-based system

      I see the point that blockchain helps make provenance tracing possible, but will need more details of how blockchain technology is leveraged here. Otherwise, I still feel stuck by questions like "Why it has to be blockchain?" and "Can't other technologies serve the same function?".

    1. the company has “reasonable plans” to onboard 100 million users on this identity platform within the next couple of years.

Right now, most of the blockchain mining in the world happens in China, where provinces with the cheapest energy set up mining operations to do the ‘proof of work’ calculations that the dominant paradigm of blockchain requires. Factories that ostensibly make other things now acquire significant computing hardware and dedicate energy in order to, essentially, print money that’s then stored offshore. A recent study shows that 40% of China’s mostly bitcoin mining is powered by coal-burning. We also already know that non-blockchain server farms in cheap energy countries consume so much energy they distort national grids, and throw off huge amounts of heat that then need cooling for the servers to operate, creating a vicious cycle of energy consumption

    1. A private blockchain still involves the record keeping of everyone's transactions by each node of this network.
    2. , private blockchain. It's organized and controlled by a known and trusted consortium of entities, like say, banks.

      private blockchain

    3. The computers connected to the blockchain network are known as nodes. Some nodes donate their processing power to solve a math problem associated with a new block. The Bitcoin community calls these people "miners,

      Nodes and Miners defination

    4. With blockchain, trust comes from the network itself. Instead of simply trusting a middleman institution, we can trust the blockchain code. The way that the blockchain is built means all parties in the system, not just the ones involved in the transaction, come to an agreement on what the facts are. And once they agree, a new block is added

      Trust in blockchain

    5. This validation process makes theft impossible by any practical measure. If you wanted to steal a bitcoin, you'd have to rewrite the coins' entire history on the block chain.

      Security of blockhain

    6. At its most basic, Blockchain is open-source code. Anyone can download it for free, run it, and use it to develop new tools for managing transactions online

      Blockchain is most stimply and The blockchain is public, it's open-source code, it's a protocol, not a product.

    1. Blockchain is tackling value industries like financial services and supply chains. These are far larger than information industries like media and publishing, and so the impact of blockchain will be that much greater, and so potentially will the aggregate value. Sometimes the saying goes, "We need a little irrational exuberance to build the future."

      Blockchain is looking beyond information. Blockchain is looking for value

    1. This is possible when all records, documents, contracts, and digital identity are verifiable as the one-and-only master copy.

      So combine the verifiability of all:

      • Records
      • Documents
      • Agreements and
      • Transactions that can be made between individuals as a new normal and you can see how 4th Density realities can shape us.
    2. In a world free of bad-actors, our societies become safer, more civil, and more trusted. Even though the heart of a person may be evil, that personal evil cannot be acted-out with data that is behind a database that leverages Blockchain methodologies.

      This makes me wonder...could this be a characteristic of 4th density? A type of openness where ALL "bad acting" is exposed to all and thereby diminished? Talk about the power of positive peer pressure!

    3. The tragedy of these heinous activities are accomplished through bad actors who are capable of hiding the truth through the primitive nature of databases within computer systems.

      Envision a "table" where money can be exchanged on top (visible business) and "under the table" (off the records).

      Think of Blockchain as a system that openly reports ALL transactions...taking out the "table"!

    4. Many of the deceptive practices mentioned below, have each become larger than any Fortune 500 Business.
      • Human Trafficking
      • Sex Trafficking
      • Drug Trade
      • Blood Diamond Trade
      • Counterfeit Products
      • Abusive Religious Belief Systems

      These are all "MONSTERS" that exist because they haven't been checked. Kinda like radio active waste from a useful energy source. If we don't bring regulation into the system, the system will self-sabotage in order to self-regulate.

      I disagree that these companies purposely prey on people. They passively prey on people by not regulating their practices and thereby leaving room for these loopholes to exist!

    5. have each become larger than any Fortune 500 Business.

      This is HUGE!

      • Slave Trade
      • Drug Trade
      • Crime and Counterfeit


    6. Blockchain is a fairly simple approach that leverages the Internet of Things (IoT), digital access to records, and the need for better security and transportability of data between people and organizations.

      Blockchain = uses direct knowledge of signal to secure it's movement and it's identity.

      • Knowing what a thing is and where a thing is.
      • Blockchain separates signal from noise.
    7. In its simplest form, Blockchain is a database designed to allow the Internet to take advantage of better security. It accomplishes this through a digital ledger (distributed-ledger) that acts like a supply-chain which defines who can access the data within the chain

      Blockchain is an elaborate list that is so openly accurate that it can be used as a security system where WE ALL SEE THE EXCHANGING HANDS

      • This means "no more money under the table"
      • Trickery is that slight of hand that deceives us!
    8. The current distrust around the globe is at its highest level due to unfair trading practices, cybercrime, false reporting mechanisms, ability to falsify documents, and the buzz word of the day …‘fake-news.’
      • Unfair trading practices
      • cybercrime
      • false reporting mechanisms
      • ability to falsify documents
      • fake news
    1. An incentive is any design element of a system that influences the behavior of system participants by changing the relative costs and benefits of choices those participants may make.
    1. unlike a traditional computer, a blockchain computer can offer strong trust guarantees, rooted in the mathematical and game-theoretic properties of the system. A user or developer can trust that a piece of code running on a blockchain computer will continue to behave as designed, even if individual participants in the network change their motivations or try to subvert the system. This means that the control of a blockchain computer can be placed in the hands of a community
    1. Aventus, Ticketchain or Blocktix tokens (all three are blockchain-based ticket issuance platforms)
    2. Basically, all token pitches include a line that goes something like this: “There is a fixed supply of tokens. As demand for the token increases, so must the price.” This logic fails to take into account the velocity problem.
    1. With an immutable, public record of every transaction,

      Só tem como ser imutável se tiver alguma garantia de que os nós não possam ser alterados, mas aí term que manter vários nós, quem vai ter interesse me manter os nós?

      5 grandes idesas a desarollar:

      1. Cripto activos: capacidad para comerciar activos digitales peer-to-peer sin pasa a traves de un banco o intermediario.

      2. identidad digital: capacidad para capturar, procesar y administrar nuestros datos, caja negra digital con el fin de que no sean administrados por google,facebook,etc

      3. smartcontracts: pieza de codigo que con un objetivo especifico que ejecuta un conjunto de instrucciones en blockchain (garantiza el cumplimiento contraactual y son autoejecutables

      4. modelos de negocio descentralizados: sin humanos

    1. Solving all those complex puzzles requires a huge amount of energy. So much energy that the two biggest blockchains in the world – bitcoin and Ethereum – are now using up the same amount of electricity as the whole of Austria. Carrying out a payment with Visa requires about 0.002 kilowatt-hours; the same payment with bitcoin uses up 906 kilowatt-hours

      cryptocurrencies require A LOT of energy

    2. The fact that no one is in charge and nothing can be modified also means that mistakes cannot be corrected. A bank can reverse a payment request. This is impossible for bitcoin and other cryptocurrencies. So anything that has been stolen will stay stolen. There is a continuous stream of hackers targeting bitcoin exchanges and users, and fraudsters launching investment vehicles that are in fact pyramid schemes.

      3rd reason for blockchain not being widely implemented: it's not safe for a general public

    3. Also, in a blockchain you aren’t anonymous, but “pseudonymous”: your identity is linked to a number, and if someone can link your name to that number, you’re screwed. Everything you got up to on that blockchain is visible to everyone. 

      2nd reason for blockchain not being widely implemented: users aren't fully anonymous

    4. Firstly: the technology is at loggerheads with European privacy legislation, specifically the right to be forgotten. Once something is in the blockchain, it cannot be removed. For instance, hundreds of links to child abuse material and revenge porn were placed in the bitcoin blockchain by malicious users. It’s impossible to remove those.

      1st reason for blockchain not being widely implemented: once something is in blockchain, it can't be removed

    5. Out of over 86,000 blockchain projects that had been launched, 92% had been abandoned by the end of 2017, according to consultancy firm Deloitte.

      Some sad statistics of blockchain

    6. It’s very slow (sometimes a transaction takes nine minutes, sometimes nine days!), a lot of hassle (try it for yourself – cutting open hard plastic packaging with scissors is more user friendly), and very unstable (its price rose to €17,000 euros; dropped to €3,000; rose again to now €10,000).

      Bitcoin transactions are slow & the currency is very unstable

    7. Not only that, but the decentralised utopia that Nakamoto dreamed about, namely avoiding trusted third parties, is still far out of reach. Ironically, there are now three mining pools – a type of company that builds rooms full of servers in Alaska and other locations way up above the Arctic circle – which are responsible for more than half of all the new bitcoin (and also for checking payment requests). 

      Blockchain isn't also yet fully free from third-parties to check the payments

    8. This is pretty inefficient. And it would be a lot less complicated if you trusted someone to manage your data (a bank, for instance). But that’s not what Satoshi Nakamoto did, which is what the inventor of bitcoin calls himself. He thought banks were bad news. They can make money disappear from your account. So he invented bitcoin. And bitcoin works, it exists, and according to the latest count, there are nearly 1,855 other bitcoin-like currencies out there.

      Why bitcoin was created to replace banks

    9. At its core, blockchain is a glorified spreadsheet (think: Excel with one table). In other words, a new way to store data. In traditional databases there’s usually one person who’s in charge, who decides who can access and input data, who can edit and remove it. That’s different in a blockchain. Nobody’s in charge, and you can’t change or delete anything, only view and input data.

      Simple explanation of blockchain

    1. They also noted that the OCEAN contract “contained a pause function for unforeseen emergencies like this one,” which calls into question the claims made by the developers of these protocols who say their platforms are “decentralized.” If they were truly decentralized, then it would not be possible to shut them down, even if there is an emergency.

      Yes, kind of not so decentralized ...

    1. Bottom line: Blockchain can help a bit with voting, but it’s not doing the most important part of the work. It doesn’t help tally secret ballots in a publicly verifiable way. It doesn’t provide individual verifiability that a ballot was correctly encoded. And it’s not useful for voting eligibility, since that’s all about human authentication and a centrally produced voter list. At best, in voting, Blockchain can be a ledger that helps us track the voting metadata.

      Blockchain can only solve some of the problems that need to be solved in a voting system. Where it falls short:

      • It doesn't help count secret ballots in a publicly verifiable way
      • It doesn't provide individual verifiability that a ballot was recorded and counted
      • It doesn't help with voting eligibility, since that's about human authentication (and a centrally maintained voter list)
    2. Then there’s the need to check voter eligibility, a critical piece of global verifiability. No matter what technology we use, we need a clear list of eligible voters, and each voter should get to vote only once. Ultimately, the list of eligible voters is set in a centralized way: it’s produced by the State. There’s nothing distributed about voter eligibility. Even when there is federation / delegation to individual counties, like in the US, there is a centralized effort to cross-check that a voter isn’t registered in multiple counties.

      The list of eligible voters is, in the modern nation state, inherently centralized. There's nothing distributed about it.

    3. In a typical election setting with secret ballots, we need: enforced secrecy: a way for each voter to cast a ballot secretly and no way to prove how they voted (lest they be unduly influenced) individual verifiability: a way for each voter to gain confidence that their own vote was correctly recorded and counted. global verifiability: a way for everyone to gain confidence that all votes were correctly counted and that only eligible voters cast a ballot.

      The requirements of the ideal voting system are:

      1. Enforced secrecy — Each voter can be sure their vote cannot be tied to their identity.
      2. Individual verifiability — Each voter can verify their vote was cast and counted.
      3. Global verifiability — Everyone can verify that all votes were correctly counted and that only eligible voters cast ballots
    4. Blockchain isn’t just a distributed database, it’s a very specific kind of distributed database where the database maintainers aren’t authenticated: anyone can be a blockchain maintainer without revealing who they are or having any kind of privileged relationship with other maintainers. the set of maintainers changes over time. New maintainers come in, existing maintainers leave, without central planning or predictability. The maintainers of the Bitcoin blockchain 5 years ago are very different from the maintainers today.

      Blockchain is a special kind of distributed database. A database where (1) the maintainers are not authenticated and (2) where there is a cycling of maintainers over time.

    1. quantum blockchain

      Do they really use a quantum blockchain? What exactly do they mean by that? Probably just a buzzword they're using to attract interest but aren't actually meaning literally.

    1. A quantum blockchain, the pair suggests, would take advantage of entanglement, which in most cases, applies to situations regarding space. But it could also be useful for situations involving time, such as blockchains. In such a blockchain, the pair explains, transaction records could be represented by pairs of entangled photons linked in chronological order. When transfers take place, photons would be created and absorbed by the hubs that comprise a network. But since entangled photons are linked across time, they can be caused to have never existed at the same time.

    1. When a user in an AWS account creates a blockchain network on Amazon Managed Blockchain, they also create the first member in the network. This first member has no peer nodes associated with it until you create them. After you create the network and the first member, you can use that member to create an invitation proposal for other members in the same AWS account or in other AWS accounts. Any member can create an invitation proposal.

      In a moment of crisis for truth and trust, it is encouraging to encounter the term deep-truth and may offer a valuable term that is both accessible and powerful in advocating not just against what we despise but for what we hope to see in a better world.

    1. Four databases of citizen science and crowdsourcing projects —  SciStarter, the Citizen Science Association (CSA), CitSci.org, and the Woodrow Wilson International Center for Scholars (the Wilson Center Commons Lab) — are working on a common project metadata schema to support data sharing with the goal of maintaining accurate and up to date information about citizen science projects.  The federal government is joining this conversation with a cross-agency effort to promote citizen science and crowdsourcing as a tool to advance agency missions. Specifically, the White House Office of Science and Technology Policy (OSTP), in collaboration with the U.S. Federal Community of Practice for Citizen Science and Crowdsourcing (FCPCCS),is compiling an Open Innovation Toolkit containing resources for federal employees hoping to implement citizen science and crowdsourcing projects. Navigation through this toolkit will be facilitated in part through a system of metadata tags. In addition, the Open Innovation Toolkit will link to the Wilson Center’s database of federal citizen science and crowdsourcing projects.These groups became aware of their complementary efforts and the shared challenge of developing project metadata tags, which gave rise to the need of a workshop.  

      Sense Collective's Climate Tagger API and Pool Party Semantic Web plug-in are perfectly suited to support The Wilson Center's metadata schema project. Creating a common metadata schema that is used across multiple organizations working within the same domain, with similar (and overlapping) data and data types, is an essential step towards realizing collective intelligence. There is significant redundancy that consumes limited resources as organizations often perform the same type of data structuring. Interoperability issues between organizations, their metadata semantics and serialization methods, prevent cumulative progress as a community. Sense Collective's MetaGrant program is working to provide a shared infastructure for NGO's and social impact investment funds and social impact bond programs to help rapidly improve the problems that are being solved by this awesome project of The Wilson Center. Now let's extend the coordinated metadata semantics to 1000 more organizations and incentivize the citizen science volunteers who make this possible, with a closer connection to the local benefits they produce through their efforts. With integration into Social impact Bond programs and public/private partnerships, we are able to incentivize collective action in ways that match the scope and scale of the problems we face.

    1. a world in which contracts are embedded in digital code and stored in transparent, shared databases, where they are protected from deletion, tampering, and revision. In this world every agreement, every process, every task, and every payment would have a digital record and signature that could be identified, validated, stored, and shared.

      The potential benefits of blockchain

    1. ) Blockchain MemoryWe let LL be the blockchain mem-ory space, represented as the hastable L:{0,1}256→{0,1}NL:\{0,1\}^{256}\rightarrow \{0, 1\}^{N}, where N≫N \gg 256 and can store sufficiently-large documents. We assume this memory to be tamperproof under the same adversarial model used in Bitcoin and other blockchains. To intuitively explain why such a trusted data-store can be implemented on any blockchain (including Bitcoin), consider the following simplified, albeit inefficient, implementation: A blockchain is a sequence of timestamped transactions, where each transaction includes a variable number of output addresses (each address is a 160-bit number). LL could then be implemented as follows - the first two outputs in a transaction encode the 256-bit memory address pointer, as well as some auxiliary meta-data. The rest of the outputs construct the serialized document. When looking up L[k]L[k], only the most recent transaction is returned, which allows update and delete operations in addition to inserts.

      This paragraph explains how blockchain hides one's individual identity and privacy, while giving them a secure way of using the funds. In my opinion lot hacker ransomware are done using block-chain technology coins, this and one more paragraph here is really interesting to read about how blockchain helps protect personal data. and i also related this this hacking and corruption or money laundering

    1. This paper explores how the Internet of Things and blockchain technology can benefit shared economy applications. The focus of this research is understanding how blockchain can be exploited to create decentralised, shared economy applications that allow people to monetise, securely, their things to create more wealth. Shared economy applications such as Airbnb and Uber are well-known applications, but there are many other opportunities to share in the digital economy. With the recent interest in the Internet of Things and blockchain, the opportunity exists to create a myriad of sharing applications, e.g. peer-to-peer automatic payment mechanisms, foreign exchange platforms, digital rights management and cultural heritage to name but a few

      This article sheds light into shared economy, have highlighted just the abstract, but this entire article is so interesting and the application it talks about is great, like how can airbnb or uber use blockchain to protect it's clients privacy. Must read
