Recently, thecompaniesrealizethatI’IoTmaybeassociate a lotoftechnologiesITand theblockchain–the technology ofdistributed register the basis ofcrytpocurrencies– is no exception. Yet, ifin certain circumstancesthesetwo phenomena can be complementary,do not expect an explosion oftechnologyIoTbases ontheblock chain.
the basis, theunderstanding ofblue chain technologyocs can be counter-intuitive.That is whyIt iswithout a doubtbest to considertheblockchainas a sort of distributed ledger thatcannedan immutable traceof thetransactions. Each blockchaincontains the recordsecureof a transactionor other datato preventIeurfalsification,eachn so muchlinked to previousby a cryptographic hash.So thatany tampering with the invalid blocktheconnection. knots– just about any material with aCPU – communicate over a networkpeer–to peerdecentralized for pashare data and ensure theirvalid in the chain.SelonNirKshetriprofessor of management at the University of North Carolina–Greensborothesystem works because all the blocksifgrantonthespecificitydata they save. If someonetrymodify a transactionalready validon a given node, the rest of the data on the networkprevents him from doing so.The old data record isimmutable,explained againNirKshetri.
Thissecurity technologyis very effective–if there is notofactormalware that manages to take control ofall nodesof thechaof blocks (the famous attackof the51%), the protected data cannot be falsified or manipulated. It is therefore notthunderousthattheblock chaininterestedbusinessesof the sectorIoT. According to JayFallah,CTOand co-founder ofNXMLabsa startupspecializedinthe safety ofI’IoT,put aside theability totheblockchain securely distribute reliable information about anetwork,the other attraction of the solution is its position in the technology stack.Block chaintosituatesa crossroadvery interesting.HASover the last 15years,computer processing has accelerated to the levelfromstorage,of theCPU,etcbutdevelopments inthenetworkingare veryrecent ,he remarked.

Complementarity ofblockchainand of theIoT
Each sellerIoTwill justify differently what makestheblock chainrelevantforits environment.Nevertheless,the point of viewby AllisonClift Jenning,CEOof filament,afoBlockchain publisher forcompany,sums it up pretty wellthe general approach.All actors whowantworkintrust,andhavethempracticeare stillveryarchaic,areofgood candidatespotentialfor blockchain,did-shedeclare.This is the case for example of thesales ofvehiclessecond hand,a subject that concernsparticularlyFilament.In fact, the companyworkit witha big jerkDetroit automakerto create a platformoftrusted vehicles.
