9、ions?Heres a brief history of how we got hereWeb1Dancing Babies,Screeching ModemsYou may or may not remember a time when the internet was accessed via a wheezy dial-up modem on a bulky,creamy beige-colored desktop computer.Depending on your connectivity,web pages loaded painfully slowly,offering ver

10、y much a read-only environment,assuming you were prepared to wait that long.Yes,you could write emails,but this was an era where connectivity to the recipient in real time was far from guaranteed-their connection was probably as slow and sporadic as your own.Nonetheless,there was a great deal of inn

11、ovation at this time as companies and entrepreneurs explored the radical changes precipitated by having access to their peers all over the world via an often censorship-free ecosystem.This was Web1 and existed around 1990-2005.This internet was“read-only”.5Web2.1Mobile,Social,Global,Fun!Around 2005,

12、some radical changes began to reach the mainstream in the evolution of the infrastructure and hardware of the internet.Broadband internet access to the home and office increasingly became de facto,meaning that there were some seismic shifts in the ways content could be delivered and monetized.Around

13、 this time,many digital service providers began moving towards streaming content since internet bandwidth could now(mostly)support this.In parallel,devices that could access the internet began the process of becoming untethered from physical cables and wires via the explosion of WiFi networks.Combin

14、ed with the emergence of touchscreen and truly portable smartphones and tablets,the internet was now something that was likely to be with you 24/7 the internet came to you,not vice versa.With this newfound connectivity and portability,users were equipped with the ability to not just email and hope f

16、y for the internet still highly anarchic and disruptive,but with the scale for people around the world to find their tribe,engage in new experiences,and to have fun.If Web1 was“read”,web2,part 1 was“read/write”,and lasted until around 2012.Web2.2 You Are The ProductIn 2012,a number of events happene

17、d that could be considered as pivotal in the second generation of Web2 /Amazon Prime began embedding video streaming as part of service this telegraphed the shift from being an online retailer to an online ecosystem for all things digital and physical./Facebook launched its IPO,and hit its one billi

19、hones./Apple launched Siri,demonstrating a new and more simplistic form of device interaction.While these events may not seem that significant in their own right,they have had seismic implications for the way that the internet has developed over the last decade,placing control into just a handful of

20、 organizations that we have come to know as“Big Tech”.These behemoths,along with newcomers such as TikTok,have reached truly gargantuan levels of adoption,building ecosystems that are mostly impenetrable without partnerships or acquisitions with them.This takes us to the present day as users we are

21、linked to digital ecosystems that would be hard to extricate ourselves from given how embedded these operating systems,search engines,social networks,and digital devices are in our daily lives.This is the era of“read/write/engage”(arguably,enrage?)Surely there is a better way?6Web1/Decentralized /Bu

24、ast decade of the online experience.Web3s rather lofty aims are to wrest the ownership and therefore control of the internet back to the end user.If web1 was“read”,and web2 was“read/write”,followed by“read/write/engage”,then the central ethos of Web3 is“read/write/own”.The true potential of Web3 res

25、ides in the ability to cut out intermediaries and therefore simplifying transactions and interactions.We will get into the enabling technology in the next section,but for now,imagine a Web2 business such as a social network.The platform is the intermediary,connecting individuals via a central portal

26、(webpage,app).The platform controls how you interact and with who,while serving up content and advertising that it believes fits your profile from data it is constantly harvesting about you.A Web3 social network would operate very differently.Instead of being centralized around a third party platfor

27、m,the network would now be based upon a decentralized web of users that directly connect to one another and collectively all own the social network.In many ways,this marks a return to the more egalitarian and open ethos of Web1,but with far more advanced and user friendly technology.Sources:Statista

28、/Researchgate,20227The Foundations of Web3It would be impossible to discuss Web3 and its implications without some basic understanding of the fabric of what makes decentralization possible,the underlying technology blockchain,smart contracts,and tokens(non fungible and otherwise).Collectively these

29、form the foundations of key attributes that separate Web3 from previous versions transparency,consensus,irrevocability,decentralization,and a system for monetization and equitable payment of participants.8BlockchainWhile the term“blockchain”has become common in the fintech vernacular,its use cases m

30、ay be somewhat misunderstood due to its association with cryptocurrencies.While blockchain has become synonymous with Bitcoin,it is not the only blockchain.At the foundation layer of Web3,there are numerous blockchains designed to have purposes well beyond the minting of digital currencies.So,what i

31、s a blockchain?Lets start with a real world analogy railways.Imagine a railway that is being built the very first pair of rails and sleeper represent a“block”,and are laid on the ground and permanently secured.In front of this,the next set is laid and again,secured to the ground.This is the beginnin

32、g of our blockchain.In time,it becomes a vast network of tracks(blocks).Here are some other attributes of our blockchain railroad /Track(blocks)can never be removed,only added to./Each track has a unique number as each additional section of track is added,the sequence of these numbers is forever cem

33、ented one in front of the next./The tracks and entire railroad are visible to all users of the network./The track continues to grow to meet traffic requirements and new destinations./The track has transparent rules for usage,such as standard rail gauges,timetables,and clear fee structures.And,most i

34、mportantly /All users of the rail network are owners,unlike previous technology where stagecoach companies were an intermediary that had to be negotiated with and paid.9So,what prevents someone from tampering with the rails and messing up this unique sequence?In a word decentralization.Every user of

35、 our railroad has access to a real time map that displays the entire network at that time,including precise details of every section of track.Because everyone has a copy of this map,any changes made would be immediately apparent to everyone.A more relatable analogy?You have a really embarrassing pho

36、to of yourself on social media.Despite your numerous attempts to delete the photo,it keeps coming back to haunt you because all of your friends have their own copy of the photo and they relish the discomfort that this particular photo elicits from you every time it appears in public.Thats the power

37、of decentralization data lasts forever and cannot be tampered with or erased.Blockchain key attributes /Distributed-the blockchain railroad is accessible to all users and all users have ownership./Global-our blockchain railroad traverses the entire globe,accessible to anyone,anywhere with the means

38、to connect to it via the internet./Security through transparency-the railroad is tamper proof,given that all users have a current map and tampering would be immediately apparent./Immutable-the blockchain railroad cannot ever be altered./Always on-the blockchain railroad never goes out of service,and

39、 is available to all users 24/7/365.Local Man Forever Known as“Hotdog Man”Blockchain Spenders WorldwideBankingProcess manufacturingDiscrete manufacturingProfessional servicesRetail29.7%11.4%10.9%6.6%6.0%Source:IDC,202010Smart ContractAnother fundamental component of Web3 is smart contracts.Without g

40、etting into the weeds,a smart contract is a computer program that resides on a decentralized network,rather than a single computer.Combining these programs together forms decentralized apps(Dapps),similar apps running on your phone or laptop.Lets extend our railroad metaphor further smart contracts

41、could be considered the engines that pull rail cars around our blockchain railroad,they are what makes Web3 happen.Should we want an engine to run,we have to pay for“gas”that is purchased using the native currency for that specific blockchain railroad network.In a Web3 context,most smart contracts r

42、un on the Ethereum blockchain(there are also numerous other blockchains that are designed for smart contracts such as Solana,Polygon and Avalanche),and the cost of getting a smart contract to run is measured in“gas”that is purchased with Ethereums native cryptocurrency ether(ETH).“Gas”fees represent

43、 payments made to the owners of the computers that are executing the smart contracts.As with the internal combustion engine,should you want your smart contract“engine”to perform faster,you may need to pay more for a higher octane fuel.Unlike traditional contracts where there is typically a buyer,sel

44、ler,and a broker in the middle,smart contracts are decentralized,directly connecting the buyer and seller with the blockchain acting as the broker by providing a permanent record of the transactions occurrence.11TITLEALICEBUYERLAWYERS,BROKERS,INSURANCESELLERBOB$ALICEBUYERSELLERBOB$TITLE“CODE AS LAW”

45、Smart Contracts key attributes /Autonomous-smart contracts can run without any human intervention,continuously,until they are turned off./Decentralized-running on the blockchain,smart contracts are visible to all users,making them tamper proof./Direct-with no intermediary,smart contracts directly co

46、nnect users./Equitable-as is the case with our blockchain railroad,everyone with access to the blockchain can view the smart contract code./Revenue generating-smart contracts require“gas”to execute.12Cryptocurrencies and Crypto TokensCompleting our railroad metaphor,we should consider the cargo that

47、 our rail network carries.Not all blockchain railroads are created the same some are designed specifically for carrying currencies,others are more universal in their design and can carry currencies as well as digital tokens.So whats the difference between coins and tokens?If a coin such as a penny o

48、r a bitcoin represents the ability to own something via purchase,a token is evidence of ownership.A physical world example of a token is a title for a car,or a deed to a property its not the actual car or the house,but proof that the car or house belongs to you,which can be transferred to another pe

49、rson if sold.In the Web3 world,tokens are the same a representation of the ownership of an asset.202220273.5Total Cryptocurrency Market Cap($Billions)The Rise and Rise of Cryptocurrency ValueSource:Statista,2022FungibilityAn important concept to understand relative t

50、o Web3 and tokens is that of fungibility and non-fungibility.Fungibility is the ability of a good or asset to be interchanged with other individual goods or assets of the same type.Fungible goods are items that are interchangeable because they are identical to each other for practical purposes.If ex

51、changing two items would be meaningless,they are fungible.In the physical world,a good example is paper bank notes.If you and I both give each other a dollar bill,the note is to all intents and purposes the same a dollar bill,carrying exactly the same value as the one I previously had in my possessi

52、on.In the Web3 world,this would apply to cryptocurrencies such as Bitcoin a bitcoin swapped for another bitcoin has exactly the same value,one bitcoin.Non-fungible goods have attributes that make them unique and therefore not interchangeable.Physical world examples could be diamonds,real estate,and

53、collectibles such as signed baseball cards.Until very recently,digital content has been fungible an MP3 recording or a JPEG image is not unique,being replicable and interchangeable indefinitely.For instance,if I do a web search for a famous painting,a Magritte maybe,I can copy and paste the image to

54、 a document of my own that is identical to the one I found.This image is fungible.13Recap-Web2 vs.Web3Returning one last time to our railroad analogy,lets compare Web2(horse and cart)to Web3(rail network)14Advantages of Web3 /A decentralized ownership every user has a vested interest in maintaining

55、the integrity of the rail network and planning for its future success./The ever-expanding rail system encourages innovation and exploration of new destinations./Its universally accessible anyone can take a train.Horse carriage travel is somewhat more exclusive,possibly involving a fee to the owners,

56、or the owners giving you free travel in return for favors./Its clear who and what is traveling for all to see,reducing opportunities for nefarious activity./Robust architecture there are multiple routes and multiple trains.There is no single point of failure,unlike horses that are less reliable and

57、more susceptible to highway robbery.Disdvantages of Web3 /It may not be the fastest route.Trains have specific timetables,stops,and are bound by the tracks they run on.The“Pony Express”is directly A to B,and therefore faster./Fuel(gas)costs can be very high at times,and the cost of crypto used to pu

58、rchase gas can fluctuate wildly.Horse travel will require buying tickets from,or giving favors to the stagecoach company,but the cost of horse feed isnt necessary./Bad workmanship(bad coding,inaccurate data)at any point on the blockchain railroad is permanently recorded,potentially causing derailmen

59、t at a future date.Web3Web2Web3 Components&Financial ServicesGiven our new found knowledge and understanding of what Web3 is and how it works,lets apply this to current financial services and assess where it can impact incumbent services.Obvious areas of disruption are where there has been a traditi

66、Web2 and Web3,that does not inoculate from disruption occurring to traditional financial services.Where disruption is most likely in financial services due to Web3 will be /Networks that have overpriced transaction fees or exorbitant interest rates due to the assumption of exclusivity.E.g.banks that

67、 charge a fee for recurring transactions would be seriously undercut./Networks that have relied on opacity and hidden fee structures for revenue generation.Interchange fees were built on the premise of scarcity of access,whereas Web3 rails would enable direct connections and thus undermine the ratio

68、nale of scarcity for interchange./Platforms with restrictive access requirements(credit score,proof of citizenship,etc.).Opening a bank account often requires a smorgasbord of documentation to prove identity.Web3 would not./Networks where fund settlement is measured in hours or days.International re

70、nsaction on their Dapp,but they couldnt charge anachronistic fees or profit from the float.If your organization resembles any of the above,Web3 could be an existential threat.Eventually.The transformation from Web2 to Web3 will be evolutionary,not revolutionary.Many Web3 initiatives in financial ser

71、vices thus far can be characterized as lacking in fundamental user centric design principles that would make them accessible for most people just the participation in any Web3 activity involves the convoluted purchase of the requisite cryptocurrencies.From here,the journey dives down a rabbit hole o

72、f gas fees,metamasks,and transactions where the more“wild west”elements of crypto come to the forefront.There is unlikely to be a help desk number for transactions that are made in error the cryptoverse is designed to be irreversible and hence can be unforgiving when fat fingered mistakes are made.R

73、ookie missteps can have expensive consequences,with each month another story surfacing of an NFT being sold for painfully discounted prices due to pilot error1.17There is also the advantage of trust that incumbent systems have cultivated over decades people understand credit and debit cards,bank acc

74、ounts,and mortgage lenders.The 2008 financial crisis notwithstanding,people trust financial institutions more than newcomers according to a 2021 study,US consumers trust banks 30 percentage points more than cryptocurrencies,and probably with good reason you can physically visit a bank branch and see

75、 the Corinthian columns and steel doors.The actual presence of banks is analog evidence that your money should be safe.By contrast,Web3 to most people is somewhere between science fiction and science project,and hasnt had the longevity to cultivate trust,particularly for financial transactions where

76、 actual money could disappear into the“ether”(pun intended)2.Finally,despite a veneer of innovation,under the hood the financial services industry is often heavily reliant on technologies that have been in place for decades.Pull any payment card from your wallet and youll see an example of just how

77、bound we are to legacy systems a magnetic stripe,technology that goes back to the 1950s.This“if it works,dont fix it”attitude pervades the financial services industry,literally to the core.A 2021 report on mainframe computer usage highlighted that that 67 Fortune 100 enterprises which includes 45 of

78、 the top 50 banks,still rely on such systems3.Displacement of the old with the new is rarely something that happens overnight in financial services.1.https:/ Trust Barometer,20213.https:/ Trust Financial Services SectorsIn summaryWeb3 is coming,but wont manifest into a decentralization revolution in

79、 a binary switch from Web2.Instead,we will see elements of Web3 be implemented into Web2 platforms in ways that will enhance efficiencies,expand global opportunities,and reduce costs.As highlighted,companies that have built businesses on opacity,obfuscation and oligarchy will find Web3 particularly

80、troublesome.Maybe not immediately,but Web3 could be as problematic for you as Voice over IP(VoIP)was for copper wire telephony.Current rumors of your demise are not overstated should you choose not to recognize the potential shifts from centralization to decentralization,and the power of smart contr

81、acts to remove intermediaries.This will be a golden age of innovation in financial services as the latent potential of Web3 technologies(blockchain,smart contracts,tokens)cross pollinate with the ingenuity of the financial services industry.The true potential of decentralized finance(DeFi)is just be

84、blockchain.The chaining of new blocks of data to form ever longer chains of blocks means all transactions recorded on the blockchain are unmodifiable(or immutable)and visible to all participants on that blockchain network.CryptocurrencyCryptocurrencies are currencies that only exist digitally and on

85、 a blockchain.Cryptocurrencies are characterized by the fact that transactions using them are verifiable and recorded on blockchain,as opposed to centralized maintenance thats a hallmark of traditional currencies.DAO DAOs,or decentralized autonomous organizations,are organizations without a central

86、authority.In contrast to traditional organizational management structures,where limited groups likes boards run them,DAOs leveragege smart contracts to execute and enforce.DappDecentralized applications or Dapps are digital applications that are built and run on a blockchain.Because Dapps exist on a

87、 blockchain,they are not controlled by a single authority.DeFiDecentralized finance,typically dubbed DeFi,is an umbrella term applied to a wave of financial services and products built on public blockchains,predominantly on Ethereum,with the aim of disrupting traditional financial services.Because i

88、ts foundation layer is blockchain technology,core to DeFi is the immutable,public,and decentralized features of blockchain.In theory,then,DeFi is antithetical to traditional financial services,where banks and other third-party institutions are necessary intermediaries.EtherEther is the cryptocurrenc
