What’sTheBlockchain?

Bitcoin is seen as the advent of an innovative new currency for the digital world.
However,anassociatedtechnologycalledtheBlockchainhasbeengettingmoreattention
lately.Thefirstquestionusuallyis,“WhatistheBlockchain,anyway?”
The simplest answer is that the Blockchain is a secure, transparent and decentralized
ledger. “Secure” doesn’t mean that it tries to hide information. It simply means that
nobody’s going to tamper with records on the Blockchain without sending up red flags
that would be very quickly noticed by alert Blockchain developers. Even if somebody
doesattempttofraudulentlyalterrecords,theoriginalrecordswillstillexistonthevalid
Blockchainandcanbepinneddownbycomparinginformationonduplicaterecords.
The Blockchain is designed to use a cryptographic hash and timestamps to make its
recordsunalterableoncetheyarecreated.ThismakesitpossibleforBlockchainexpertsto
inspect records on the Blockchain to determine the facts of any given transaction or to
detect attempts to tamper with the ledger. As we saw with the swift reaction to a faulty
updatein2013,anaccidentaltechnicalglitchthataffectstheBlockchain’sabilitytocreate
reliablerecordscanbequicklyisolatedandshutdown.Thesameprinciplesthatmadethat

Bitcoin’sdecentralizedBlockchainledgerensuresthatnopartyinatransactionwillhave
to trust any single third party to essentially hold their money for them. While the
technology behind the Blockchain can be used to create an effective automated escrow
system,thebasicsystemisnotgoingtodisappearwithyourmoneyordenyyouaccessto
your account. That gives Bitcoin its power as a currency that can cross international
borders,providequicksettlementsandavoidbeingcontrolledbyanycentralizedauthority.
MaintainingtheBlockchainreliesontheoperationofmultiplenodesthatarecapableof
storingtransactiondataandtheoperationofprocessorsthatcanvalidatenewdata.Think
ofthenodesascompletelyequalserversthatregularlyupdateoneanotherwithdataand
make it possible for authenticated clients to connect to them, if you like. The multiple,
regularlyupdatednodesbuildsinaconsiderableamountofredundancyintothesystem.If
anodemalfunctions,theITstaffcanworkwithaBlockchainexperttoisolatetheserver
and troubleshoot that node to determine what went wrong. Common malfunctions will


usually involve a node’s failure to transmit valid records. It may transmit records that
makenosensetoothernodes.Itmayrefusetotransmitanysortofdataatall.Itmight“go

business owner who doesn’t want to explain to frustrated clients why a server in a

demonstrates the Blockchains capacity to become effectively the “World Wide Web” of
finance.AprivateversionoftheBlockchaincanworkifeachbranchofabusinesswith

WhatMakesTheBlockchainSecure?

TheoriginalversionoftheBlockchainmakesuseofacryptographichashknownasSHA256. It’s secure, but so inefficient that specialized hardware called mining rigs has been
createdspecificallytohandlethejobofprocessingtransactions.Theseminingrigssolve
mathematicalproblemscalledhashestoconfirmandrelayvalidtransactions.
Each solved hash represents one block – a bundle of processed transactions that can be
relayed to all valid nodes. The cryptographic information on each block of records is
basedontheinformationassociatedwiththelastblockandcontainsauniquetimestamp,
whichmakesvisualizationsoftheBlockchainlooklikelinksinachain.Infact,theterm
“Blockchain” comes from the idea that it’s a cryptographically secured chain of record
blocks.
This chain of blocks makes it easy to detect attempts to fraudulently add records to the
chain.Imaginethatyou’readdinglinkstoachainandsomeonecomesalong,choosesa
linkinthemiddleofthechainandstartsaddinghisownlinkstothatlink.Thechainhas
justbeenforked.TheBlockchaincanbesimilarlyforkedandactuallywasforkedbythat
faultyupdatein2013,buttheswiftreactionbyBitcoindevelopersshowsthatit’spossible
toquicklyrecognizeandisolateafraudulentforkifithappens.
Why would somebody fraudulently fork a Blockchain? They might do it because they
want to falsely edit a record that already exist on the chain, so they fork the chain just
beforetheblockthatcontainsthatrecord.Thismaybecomeacommontacticwithanyone
whowishestofraudulentlyalteracontract,deedortitleifattemptstoforkthechainare

or two and a few modest mining rigs to work on validating new records as part of the
process of rebooting it. (Of course, that would be the EASY part when it comes to

Inbothcases,it’ssimpleenoughtocomparethecryptographichashandtimestampofthe

fork was resolved by warning miners to not switch over to the “new” version of the
Bitcoin Blockchain. Although the Blockchain is designed to be secure, this also

This is actually one of the benefits of having a decentralized system that can handle
multiple nodes in more than one location. It’s easy to isolate a “rogue” node for
troubleshootingwithoutcompromisingtherestofthesystem.Thebehavingnodescanjust
keep plugging away, creating new valid records and making them available for anyone
who wants to inspect or use them, while the Blockchain expert investigates what went
wrong with the misbehaving node. Then, once the matter is settled, the fork can be
resolvedandtherepairednodecanbeaddedtothenetworkagain.

that you knew precisely what you were agreeing to. If you wake up and your garage is
empty because you missed payments on your car loan, at least you’re going to know
where you car is at. On the flip side, the Blockchain protects your rights, too, by
automating the process of logging payments. You can make your monthly payments by

HowInclusiveIsTheBlockchain?

Modern Western society cares about including as many people as possible in its
socioeconomic system, but the centralized financial system hasn’t gotten the memo yet.

Kenya’s MPesa is a success for exactly this reason. If an entrepreneur is considering

The Blockchain can do the same thing because, well, it was introduced as part of the
Bitcoin package. Bitcoin gambling sites use the term “provably fair” to show that their
algorithms have not been unfairly weighted against its players even when the odds are
already against them. Dice games are hard enough to win even when the dice aren’t
loaded. Entities that are interested in using the Blockchain should adapt the concept of
