Advantagesofblockchain applicationBlockchain hasthefollowingadvantagesoveraconventionalcentralizeddatabase:1. Security:Blockchain relies onencryptiontovalidatetransactionsbyverifyingtheidentitiesofparties involvedinatransaction.
Thisensuresthata“false”transactioncannotbeaddedtotheblockchain withouttheconsentofthepartiesinvolved.Acomplexmathematical calculationknownasa“hash”isperformedeachtimeatransactionisaddedtotheblockchain,whichdependsonthetransactiondata,theidentities oftheparties involvedinthetransaction,andtheresultofprevioustransactions.Thefactthatthecurrentstateoftheblockchain dependsonprevioustransactionsensuresthatamaliciousactorcannotalterpasttransactions.Thisisbecause ifprevioustransactiondataischanged,itwill impactthecurrentvalueofthehashandnotmatchothercopiesoftheledger.
2. Transparency:Byitsverynature,blockchain isadistributeddatabasethatismaintainedandsynchronizedamongmultiplenodes– forexample,bymultiplecounterpartieswhotransactwitheachotherfrequently.Inaddition,transactiondatamustbeconsistentbetweenpartiesinordertobeaddedtotheblockchain inthefirstplace.Thismeansthatbydesign,multiplepartiescanaccessthesamedata(insomecaseslocallywithintheirorganizations)– thussignificantlyincreasing theleveloftransparencyrelative toconventionalsystemsthatmightdependonmultiple“siloed”databasesbehindfirewalls thatarenotvisibleoutsideasingleorganization.
3. Efficiency:Conceptually,maintainingmultiplecopiesofadatabasewithblockchain wouldnotappear tobemoreefficient thanasingle,centralizeddatabase.Butinmostreal-worldexamples(includingseveralofthecasestudiesweexamine incapitalmarkets),multiplepartiesalreadymaintainduplicatedatabasescontaininginformationaboutthesametransactions.Andinmanycases,thedatapertainingtothesametransactionisinconflict– resultingintheneedforcostly,time-consumingreconciliation proceduresbetweenorganizations.Employingadistributeddatabasesystemlikeblockchain acrossorganizationscansubstantiallyreduce theneedformanualreconciliation, thusdrivingconsiderablesavingsacrossorganizations.Inaddition,insomecases(seeourdiscussionofAML)blockchain offersthepotential fororganizationstodevelopcommonor“mutual”capabilities thateliminate theneedforduplicationofthesameeffortamongmultiple organizations.

Conclusions
Futurechallenges:• Criticalmassofcounterpartyinformation.Criticalmassofinformationisneededinorderfordatatobecommerciallyreliable.Forexample,incaseswherethereisascarcityofvalidatedcounterpartyinformation(e.g.,validatedonlybyasinglesource),weexpectbankswouldstillneedtoruntheirownKYCchecksand/ortransactionsurveillancetoindependentlycorroborateclientinformation.
• Regulatoryreform.Regulatoryreformthatsupportsblockchain-basedapplicationswillbeneededbeforefinancialinstitutionsareabletoembracethetechnology.Whileblockchain willlikelynotremovebanks’AMLliability,blockchain-baseddistributedledgerswillneedtobelegitimizedbygoverningbodies(i.e.,fiatcurrency)inorderforbankstocomfortablyrelyonthemasasourceofcounterpartyinformation.
• Infrastructuredevelopment.Thedevelopmentofblockchain-basedinfrastructurethatoperatesinconjunctionwithexistingindustrystandardsisneededforcommercialadoption.Forexample,wenotethatwiretransferinformation(e.g.,ABAroutingnumbers)willneedtobetiedtoablockchain indextoimprovethesecurityofmoneymovementtransactions.Assuch,webelieveconsiderableinvestmentisneededtoimplementrequisiteinfrastructure.
