A non-advisory look back at a 2023 crypto watchlist across payments, mobile-first finance, privacy, scaling, app chains, enterprise ledgers, CBDC infrastructure, DAGs, and IoT networks.
This article is best read as a historical 2023 snapshot, not a current buy list. Crypto markets move quickly, and a watchlist from early 2023 reflects the narratives, expectations, and technical themes that were visible at that moment.
The original list mixed two broad categories: blockchain networks and DAG-style distributed ledgers. The common theme was scalability, user experience, enterprise adoption, payments, privacy, and real-world use cases after the 2022 bear market reset.
Payment and remittance networks were one category to watch. The investment thesis was that fast settlement, institutional partnerships, and cross-border payment use cases could keep some networks relevant even when speculative markets cooled. The risk was regulatory uncertainty, centralization concerns, and whether bank partnerships translated into durable token demand.
Mobile-first financial inclusion was another theme. Networks focused on smartphones, low-cost payments, stablecoins, and emerging-market access aimed to make crypto usable for people outside traditional banking rails. The challenge was adoption: financial inclusion requires distribution, compliance, liquidity, and simple user experience, not just blockchain throughput.
Privacy-focused chains appeared because users and institutions need confidentiality in some contexts. Privacy can protect legitimate users, but it also creates regulatory scrutiny and liquidity challenges. The long-term question is whether privacy tools can balance compliance, user protection, and censorship resistance.
Ethereum scaling and sidechain ecosystems were central to the 2023 conversation. High fees had pushed users and developers toward lower-cost environments. The opportunity was cheaper application deployment and enterprise experimentation. The risk was bridge security, fragmented liquidity, and whether activity would remain once incentives faded.
Developer-friendly smart-contract platforms emphasized usability, sharding, web-based wallets, and simpler onboarding. These networks competed to attract builders who wanted better performance and smoother user experiences. Their success depended on tooling, grants, community, liquidity, and real applications rather than technical claims alone.
On-chain web hosting and application infrastructure represented a different bet: that blockchains could host more than tokens, including websites, files, identity, and full-stack applications. That category raised important questions about cost, decentralization, governance, developer adoption, and whether users could notice the difference.
DAG and hashgraph-style systems offered an alternative to traditional blockchains by pursuing high throughput, low fees, and enterprise-grade consensus. These architectures were often marketed for supply chain, carbon markets, CBDC pilots, enterprise ledgers, and IoT. The risk was that enterprise interest does not always translate into open-network value capture.
CBDC and smart-city infrastructure narratives also appeared in 2023. Governments and institutions were exploring digital settlement, tokenized assets, and payment modernization. Crypto investors watched these projects because public-sector adoption could validate distributed-ledger infrastructure, though the value path for public tokens remained uncertain.
IoT-focused ledgers made sense conceptually because machines may need lightweight payments and data integrity. The problem was timing: IoT adoption, hardware deployment, standards, and business models move slowly. A technically elegant ledger still needs devices, customers, and economic demand.
The durable takeaway from the 2023 watchlist is sector-based thinking. Instead of treating every token as a generic trade, investors and analysts should ask what category it belongs to, what problem it solves, who uses it, how the token captures value, and what risks could break the thesis. Historical lists are useful when they teach that framework rather than when they are followed blindly.
