Welcome to the Appchain Era: Blockchains Built for Business
Blockchain technology first emerged in 2009 with Bitcoin, revolutionizing the world of digital currencies and payments. But in recent years, developers have realized blockchains can enable much more than just peer-to-peer digital cash transactions. Enter appchains: blockchains designed and optimized for specific applications beyond payments and cryptocurrencies.
Appchains, also called application-specific blockchains, utilize blockchain architecture to build decentralized networks and systems tailored for particular use cases. Much excitement surrounds appchains and their potential to transform multiple industries through enhanced transparency, efficiency, security and innovation.
Defining Application-Specific Blockchains
At its core, a blockchain forms a decentralized ledger - a continuously updated record of transactions distributed across many computers without centralized control. This allows digital information to be recorded and distributed transparently while preventing tampering or revision.
The first blockchain emerged to track exchanges on the Bitcoin network. But developers soon realized blockchains' potential extends far beyond managing a digital currency. Just as the internet revolutionized communications through information sharing, blockchains enable secure data sharing across decentralized networks regarding digital transactions and value exchanges of all kinds.
However, Bitcoin's blockchain lacks the flexibility and scalability required to handle high transaction volumes required by global scale applications. This led developers to create appchains - blockchains engineered to optimize specific use cases handling sensitive information exchanges across industries like finance, supply chains, gaming, music, medicine and more.
Appchains provide the benefits of traditional blockchains like transparency, accuracy, automation and security while overcoming scalability limits through customization. They allow streamlined management of data integrity and sharing rules between specific participating entities.
Architectural Composition
Appchains utilize the same fundamental architecture as traditional blockchains. Data records containing key information like time, date, participants and transaction details are grouped together to form blocks. Cryptography seals blocks with digital signatures and timestamped identifiers, chaining them sequentially into an ongoing ledger.
However, unlike conventional blockchains, appchains are privately developed by companies and consortiums to perform niche functions under customizable governance protocols. While anyone can join and run the Bitcoin blockchain, participation in appchains is restricted to verify identities and regulate write permissions based on complex data sharing policies between designated users.
Access constraints account for appchains’ vastly increased processing capacity compared to public networks. Bitcoin’s blockchain handles only 7 transactions per second due to decentralization tradeoffs. Private appchains achieve over 3000 TPS through controlled participation. Additionally appchains enhance functionality with embedded logic programming allowing smart contracts to automatically execute complex multi-party workflows.
Designed for commercial integration, most appchains utilize permissioned governance models. Approved validators vote on updates based on proprietary stake weight or identity verifications. Some appchains enable hybrid models blending open and closed elements like allowing read-only public access. Overall appchains sacrifice degree of decentralization for speed, functionality and regulatory compliance by limiting consensus participation to select validated entities.
Benefits Over Traditional Systems
Appchains aim solving distinct organizational problems by strategically leveraging facets of blockchain technology including:
Immutability: Records cryptographically sealed makes tampering extremely difficult, providing accurate auditing.
Transparency: Permissioned access allows sharing valuable data securely between mistrusting entities and users, enabling collaboration.
Automation: Information integrations and smart contract workflows cut labor costs while accelerating complex multi-party coordination.
Innovation: Rapid prototyping of blockchain-based systems spurs inventive solutions and efficiencies.
While traditional databases can enable aspects of data sharing and automation, appchains formulations utilize unique blockchain qualities around trust and accountability optimized for enterprise solutions. Distinguishing advantages include:
Data Integrity: Appchains immutably preserve dataset history with timestamps allowing changes to be reviewed retroactively.
Process Continuity: Consensus protocols minimize downtimes enabling consistent 24/7 execution of time-sensitive functions and smart contracts.
Security: Encrypted data exchange protects corporate datasets while auditable access logs strengthen accountability.
Cost Reduction: Eliminating middlemen slashes financial, temporal and labor expenditures.
Regulatory Compliance: Custom governance policies enhance transparency monitoring with strict yet updateable guidelines tailored regulatory environments.
These benefits make appchains appealing for securely streamlining multi-party workflows, sharing sensitive information, automating complex tasks and reducing redundancy across organizational boundaries. The ability to track data provenance while demonstrating compliance also proves valuable in regulated environments like healthcare and finance.
In summary, appchains overlay permissioned governance and access policies upon foundational blockchain architectures to provide customizable enterprise solutions for securely sharing information and value across entities. This drives new efficiencies while retaining decentralized qualities around accuracy, transparency and collaboration.
Real-World Appchain Examples
Myriad appchain applications now tackle specialized coordination challenges across sectors:
Supply Chain
Tracking assets across firms necessitates sharing shipment data openly while protecting proprietary details - an ideal appchain use case. For example IBM Food Trust uses an appchain to trace food origins across the farm-to-table supply chain via scanned QR codes, optimizing visibility, safety recalls and inventory. Walmart piloted the blockchain program significantly improving recall speeds. Other supply chain blockchains like TradeLens (developed by Maersk and IBM) also help coordinate cargo flows using appchains.
Finance
Financial companies like Santander Bank and American Express have developed appchains to facilitate global B2B payments and loyalty point transfers. Major stock exchanges like Australia's ASX are also replacing legacy settlement systems with appchains to process equity transactions faster. Such blockchains aim modernizing financial infrastructure by enabling seamless value exchange and data sharing across banking partners.
Healthcare
Health utilities like Solve.Care coordinate patient care via appchains that securely share medical records between hospitals and insurers using access permissions. Benefits include transparency over treatments and automated payments. Medical chain MediLedger tracks pharmaceutical shipments down supply channels to verify authenticity and prevent counterfeiting enabling transparency between distributors, producers and pharmacies.
Government
The state of Illinois uses a blockchain for digital birth certificate issuance while Brazil uses an appchain to verify the legitimacy of government-issued documents like driving licenses. Such applications help ensure citizens obtain and share verified official records across departments and jurisdictions. Estonia has one of the most advanced e-Governance appchain programs with various public services running on blockchains.
