1.2 Blockchain technology distributed ledger (BTDL)

A blockchain is a form of distributed ledger technology that records transactions across a network of computers or nodes. Rather than being stored in a centralized server, the ledger is distributed among independent nodes that share and synchronizethetransactionsintheirrespectiveelectronicledgers.Toenableblockchainapplications,severaltechnologies are employed, including digital signatures, distributed networks, and encryption/decryption methods. Transactions on the blockchainarerecordedwithanunalterablecryptographicsignaturecalledahash,whichiswhydistributedledgersareoften referredtoasblockchains.

Thiscryptographicsignatureensuresthattherecorded transactionscannot be tampered with oralteredinany way,making blockchaintechnologyhighlysecureandtransparent.Blockchaintechnologyisadigitalledgertechnologythatenablessecure, transparent, and decentralized peer-to-peer transactions without the need for intermediaries. At its core, blockchain is a distributedledgerthatrecordseverytransactionorpieceofdataacrossanetworkofcomputers,creatingan unalterableand transparentchainofinformation.

5. PROBLEM IDENTIFICATION
Blockchain technology, although highly promising, has several limitations that affect its adoption and suitabilityfordigitalmarketing.Twosignificantchallengesfacedbycompaniesinterestedinusingblockchaintechnologyfor theirdigitalmarketingneedsarelimitedscalabilityandlackofstandardization.
Firstly, blockchain technology has limited scalability, which means it may not be able to handle the large volumes of transactions required for digital marketing. Blockchains operate through a decentralized network of nodes that validate transactions and record them on a distributed ledger. However, the more transactions that are processed, the more the networkbecomescongested,andtheslowertheprocessingspeedbecomes.Thisissuecanmakeitchallengingforcompanies thatneedtoprocessahighvolumeoftransactionsquickly,suchasthoseinvolvedindigitalmarketing.
Secondly, the lack of standardization in the blockchain industry can make it difficult for companies to choose the right blockchain solution for their digital marketing needs. There are many different blockchain platforms available, each with its ownuniquefeaturesandcapabilities.Thiscanleadtofragmentationandinefficienciesintheindustry,ascompaniesmaynot beabletocommunicateorexchangedataeffectivelybetweendifferentblockchains.
6. Proposed System
Using a consumer-centric model can be a useful approach to address scalability and standardization problemsrelatedtoblockchaintechnologyindigitalmarketing.
Scalability: One way to address scalability is to create a consumer-centric model that encourages users to participate in the blockchain network. This can be achieved by providing incentives such as loyalty programs, discounts, or other rewards for userswhoparticipateinthenetwork.Byincentivizinguserstoparticipateinthenetwork,companiescanincreasethenumber ofnodesontheblockchain,whichcanimprovescalability.
Standardization:Aconsumer-centricmodelcanalsobeusedtoaddressthelackofstandardizationintheblockchainindustry. By creating consumer-centric standards, companies can develop common language and practices that are easily
understandableandaccessibletoconsumers.Thiscanleadtogreateradoptionofblockchaintechnologybyconsumers,which in turn can drive greater standardization in the industry. In add-on to a consumer-centric model, other solutions to address scalability and standardization problems may include industry collaboration, the development of interoperability protocols, and the use of open-source solutions. By working together, companies and stakeholders can develop solutions that are scalable, standardized, and accessible to a broader range of users. This can help to increase adoption and drive greater innovationintheblockchainindustry.Whenitcomestoimplementingaconsumer-centricmodelusingblockchaintechnology, thereareseveralstructuresandalgorithmsthatcanhelpaddressthescalabilityandstandardizationchallenges.
One potential solution is to useoff-chainsolutions, suchasstatechannels or sidechains, whichallow for faster andcheaper transactions. These solutions can be particularly useful in a consumer-centric model where quick and low-cost transactions areessentialtoprovidingaseamlessuserexperience.
