The Worldwide AIS Network (WAKE) is pioneering a new frontier in maritime technology by creating a decentralized Automatic Identification System (AIS) validation network. AIS is the ship tracking system that vessels use to broadcast their identity, location, and course to others at sea. However, AIS data today is fragmented and vulnerable to spoofing or manipulation, which undermines trust in maritime intelligence. WAKE’s mission is to bring Web3 principles to this domain, crowdsourcing real-time ship tracking data from a global community of receivers, and securing it on a tamper-proof blockchain ledger for verifiable marine intelligence.
To achieve this at global scale, WAKE has selected Polkadot as its base layer infrastructure. In this article, we explore why build on Polkadot for a use case like WAKE, and how Polkadot’s architecture, from Coretime scaling to the upcoming JAM upgrade provides the scalable blockchain infrastructure needed for trustless AIS data validation. WAKE is currently in a proof-of-concept stage on Polkadot’s Westend testnet, demonstrating how decentralized sensor data (like ship locations) can be reliably collected and verified. The following sections will delve into WAKE’s requirements and Polkadot’s strengths: from massive throughput and security to future-proof design.
Why WAKE Needs a Specialized Blockchain
AIS data presents a unique challenge: it’s high-volume, real-time, and mission-critical. Every day, hundreds of thousands of vessels continuously broadcast position reports; over a year these transmissions add up to billions of messages globally. Traditional blockchains (like first-generation smart contract platforms) are not designed to handle such throughput or frequency at a reasonable cost. Moreover, AIS signals are unencrypted and have been tampered with in the past, for example, malicious actors have faked AIS broadcasts to hide sanctioned vessel movements. This highlights the need for a tamper-proof data layer where multiple independent nodes can cross-verify ship reports, and once recorded, the data cannot be altered. A centralized database might process AIS feeds, but it would require stakeholders to trust a single authority (and that authority’s cybersecurity) to ensure data integrity. WAKE’s approach is to use blockchain to achieve trustless data validation: ship location data is contributed by many participants and validated in a decentralized manner, making it extremely difficult for any one party to falsify the record.
To implement this, WAKE need to deploy on a specialized blockchain built for handling vast amounts of data. By using Polkadot’s blockchain framework (Substrate), WAKE can custom-build its own chain optimized for AIS use cases, for example, tailoring how data is stored and validated, and creating a native token ($WAKE) to reward data contributors. This dedicated approach means WAKE isn’t competing with DeFi transactions or NFTs for bandwidth; it has a blockchain environment purpose-built for maritime data. The specialization extends to on-chain logic as well, WAKE’s chain can include domain-specific rules (like validating whether a reported ship position is plausible by comparing multiple sources or timestamps).
Why Build on Polkadot (Core Strengths)
Polkadot is often described as a layer-0 multichain network, essentially a scalable blockchain infrastructure designed to host many specialized blockchains (called parachains or roll-ups) under one umbrella of security and interoperability. WAKE chose Polkadot for several core strengths that align with its needs:
Throughput at Global Scale: Polkadot’s architecture enables parallel transaction processing across multiple chains. Rather than all activity clogging one single blockchain, Polkadot can run many blockchains simultaneously, each processing its own transactions in parallel. The network’s capacity scales with the number of “cores” (parallel processing units) in the relay chain. In fact, the Polkadot Relay Chain is theoretically capable of supporting about 100 parallel cores, and testing has already demonstrated roughly 80 parallel chains running with 12-second blocks. Polkadot recently introduced asynchronous backing, which halved the block time from 12 seconds to 6 seconds, effectively doubling each chain’s throughput. Thanks to this design, Polkadot can handle an enormous volume of transactions. For context, Polkadot’s TPS (transactions per second) throughput has been measured at up to 142,000 TPS with the network only ~23% utilized, indicating ample headroom for growth. This level of performance is critical for WAKE, AIS messages flood in from all over the world, and Polkadot provides the throughput to validate those incoming data points in real time without bottlenecks.
Shared Security and Decentralization: When a project builds on Polkadot, it doesn’t have to recruit its own independent set of miners or validators from scratch. Instead, all parachains on Polkadot benefit from the shared security of Polkadot’s central relay chain, which is maintained by hundreds of validators around the world. Polkadot’s validator set and staking mechanism are known for being highly decentralized. One metric of decentralization is the Nakamoto Coefficient, which is the minimum number of independent parties needed to collude to compromise the network. In a proof-of-stake network like Polkadot, this effectively means the number of top validators required to control 33% of the staked DOT (since >33% could disrupt consensus). Polkadot boasts a very high Nakamoto Coefficient, recently rose to 175, higher than most leading networks. In simple terms, it would require dozens upon dozens of independent validators to work together (an extremely implausible scenario) to attack Polkadot’s chain. For WAKE, this translates to a trustworthy base layer. The AIS data in WAKE’s network will be secured by Polkadot’s robust consensus and wide distribution of validators, making it tamper-resistant and reliable. Even infrastructure investors and analysts can appreciate that Polkadot’s security model means lower risk of central points of failure, an important consideration for real-world applications like maritime monitoring.
Interoperability and Composability: Polkadot is built for cross-chain interoperability via its XCM (Cross-Consensus Message) protocol. That means the WAKE rollup (once live) will be able to communicate and exchange data or value with other parachains on Polkadot and even external networks via bridges. This is a forward-looking benefit: for example, verified AIS data from WAKE could be consumed by other decentralized applications, perhaps an insurance platform (on another rollup) that automatically adjusts premiums for cargo ships based on voyage history, or a supply chain blockchain that references WAKE’s data for tracking shipments. Because Polkadot treats the entire ecosystem as one interoperable network, real-world blockchain use cases can be composed across domains. WAKE’s data becomes a piece of marine Web3 infrastructure that any other appchain can trust and utilize without going through centralized APIs.
On-Chain Governance and Upgradability: Polkadot has a sophisticated on-chain governance system and forkless upgrade capability. This means as WAKE evolves, it can benefit from Polkadot’s ability to upgrade itself (and by extension, rollups can upgrade) without disruptive hard forks. Polkadot’s roadmap is very forward-looking, features like agile coretime, elastic scaling, and the upcoming JAM upgrade (discussed later) are all part of Polkadot’s plan to continuously expand capacity and capability. By building on Polkadot, WAKE is essentially aligning with an infrastructure that will keep pushing the boundaries of scalability and decentralization, rather than a static platform.
Polkadot provides the right mix of scalability, security, and flexibility. It offers WAKE a base layer where a specialized AIS blockchain can thrive: massive parallel throughput to handle global sensor data, a high-security validator network to ensure tamper-proof records, and a path to integrate with the broader Web3 ecosystem. These core strengths answer the question of “why build on Polkadot” for a project like WAKE. Next, we will examine how one of Polkadot’s key concepts – Coretime – is leveraged to scale WAKE’s global validation layer.
How WAKE Will Use Coretime to Scale a Global Validation Layer
One of Polkadot’s fundamental innovations is the concept of Coretime. In Polkadot, the relay chain’s processing power is divided into multiple virtual cores, each of which can be allocated to execute a parachain’s block. In essence, coretime is the time allocated on one of Polkadot’s cores, for example, using one core for one block’s execution (Polkadot blocks occur in roughly 6-second slots). A more formal definition: Coretime is the resource of a Polkadot virtual core’s processing time that a parachain consumes. This is important because Polkadot’s design allows flexible scheduling of these cores among parachains or other workloads. WAKE plans to utilize this model to achieve global-scale data validation.
Concretely, as WAKE transitions from the Westend testnet to mainnet, it can secure a slot on Polkadot, which is essentially reserving continuous coretime for WAKE’s blockchain. By having a parachain slot, WAKE will get a guaranteed execution slot on a Polkadot core every relay chain block (every 6 seconds). This consistent rhythm gives WAKE the ability to ingest and validate incoming AIS messages from around the world in near-real-time. Every block, WAKE’s chain could be processing a batch of new ship position reports, running its validation logic (cross-checking multiple data feeds to detect any anomalies or spoofing), and finalizing those data points on-chain. The scaling advantage comes from the fact that if WAKE’s throughput needs grow, Polkadot’s agile coretime feature allows for additional flexibility. Parachains can purchase extra coretime on demand, meaning if the AIS network sees a sudden surge in messages (imagine a major global event where many ships transmit alerts simultaneously), WAKE could theoretically tap into additional blockspace as needed. Polkadot is introducing coretime markets where projects can bid for more frequent block inclusion or even split their workload across multiple cores.
Because Polkadot treats blockspace as a flexible commodity, WAKE can scale horizontally. It isn’t confined to a single monolithic chain trying to do everything; it operates within Polkadot’s multichain cloud of resources. If needed, WAKE’s network could even deploy specialized logic in separate but connected chains (for example, one could imagine a future where one parachain handles the raw AIS data ingestion and another focuses on complex analytics, both secured by Polkadot and interoperating). But even on one chain, the capacity is vast. With Polkadot capable of running dozens of parallel chains, the elastic scaling potential means WAKE will not easily hit a performance ceiling. As Gavin Wood (Polkadot’s founder) and Parity Technologies have demonstrated, Polkadot’s relay chain can be optimized to run more cores as technology improves, it’s not limited to a fixed number. This gives infrastructure investors confidence that a network like WAKE can grow in usage from a pilot to full global deployment without needing to re-platform.
The Role of JAM in Enabling Marine Web3
Polkadot is not standing still. As WAKE builds on Polkadot’s current technology, it also stands to benefit from Polkadot’s ambitious roadmap, notably the upcoming JAM upgrade. JAM stands for Join-Accumulate Machine, and it represents a proposed next-generation design for Polkadot’s core system. Announced by Dr. Gavin Wood in 2024 via the Gray Paper, JAM is envisioned as a comprehensive evolution of Polkadot’s architecture to achieve even greater speed, scalability, and flexibility. In Gavin’s own words, this new design aims to “revolutionize Web3 with enhanced speed, scale, full decentralization, and user-friendliness”
What exactly is JAM, and why does it matter for a project like WAKE? At a high level, JAM will merge the concepts of smart contracts and parachains into a unified platform. Today, Polkadot’s relay chain is mostly a coordinator, it secures parachains but doesn’t itself run arbitrary application logic beyond governance and staking. JAM proposes to replace the relay chain with a more general-purpose engine that can directly host decentralized applications and rollups in a transactionless model. The name “Join-Accumulate” comes from the two core functions that this machine performs: it will join inputs (collect and combine off-chain work results) and accumulate them into the global state. Essentially, Polkadot would become a rollup-centric multi-core blockchain. Instead of thinking of parachains producing blocks, we think of numerous services running, each refining off-chain data and then joining the results on-chain in an accumulated state. It’s a bit technical, but the key takeaway is massive scalability and simpler development: developers could deploy services without needing a full blockchain parachain, by just specifying certain functions (refine, accumulate logic) that the network runs.
For WAKE and the notion of marine Web3, JAM could be a game-changer. Imagine a future where WAKE doesn’t even need a separate chain slot – it could run as a service on Polkadot’s core chain under JAM, where the heavy lifting of AIS data processing is done off-chain (perhaps in many nodes globally), and Polkadot simply joins and validates the results. The JAM model is designed to handle high-volume rollup data with integrity checks on-chain. In fact, one of JAM’s design goals is to enable Polkadot to handle hundreds of parallel workloads and even integrate zero-knowledge proofs and other advanced scaling techniques natively. Polkadot’s current multi-chain approach already offers WAKE what it needs for now, but JAM promises to push the envelope further: true elastic scaling (Polkadot with JAM is expected to handle hundreds of chains/programs concurrently), and possibly more efficient use of resources by eliminating the concept of discrete transactions in the base layer.
In practical terms, as WAKE grows, the JAM upgrade could allow it to seamlessly tap into even more performance. The Polkadot community is actively working on this upgrade (with a JAM specification released and prototypes in progress). By building on Polkadot, WAKE is future-proofing its platform as Polkadot evolves to Polkadot 2.0 (the era of JAM), WAKE can transition along with it, gaining speed or capacity without a complete rebuild. Also, the JAM Gray Paper by Gavin Wood lays out a vision of Web3 where even data-heavy, real-world applications (like IoT sensor networks, which WAKE essentially is for ships) are first-class citizens on the blockchain. WAKE’s use case, a decentralized network of physical sensors feeding a blockchain for a public good (maritime safety and intelligence), exemplifies what Polkadot’s next evolution aims to empower. In a sense, WAKE is exactly the kind of real-world blockchain use case that Polkadot’s design (present and future) is tailored for: one that demands high throughput, strong security, and the ability to integrate with off-chain systems and data.
What This Means for Real-World Blockchain Use Cases
The collaboration between WAKE and Polkadot illustrates a broader point: blockchain technology is maturing to handle real-world, data-intensive applications beyond finance. By leveraging Polkadot, WAKE is demonstrating that a decentralized sensor data network can operate at global scale. This has implications across industries. If we can trustlessly validate and log AIS maritime data, we could do the same for other domains: think of supply chain tracking, environmental sensor networks, air traffic control data, or smart city IoT streams. The Polkadot approach, using specialized blockchains (or future JAM services) under a shared security umbrella, can provide a template for these real-world use cases. Each domain can have its own chain or service optimized for its data and rules, while relying on a common base layer for security and interoperability.
The key takeaway is that scalable blockchain infrastructure like Polkadot lowers the barrier for deploying such networks. WAKE did not have to invent a blockchain from scratch and convince a global set of miners to secure it; it can plug into Polkadot and focus on the application logic (i.e., how to best validate AIS signals). This accelerates time-to-market and gives confidence that performance will not be an issue. Moreover, Polkadot’s economic model (e.g. paying for coretime, using DOT for security) aligns incentives for long-term sustainability of these networks. For the maritime industry, WAKE’s Polkadot-based network could unlock new value: more transparent and reliable shipping data, better analytics for ports and insurers, and community-driven maritime intelligence that was not possible before. And importantly, it achieves this without centralization, data contributors are rewarded, no single company owns the dataset, and all stakeholders can verify information on-chain.
From an investor or analyst perspective, WAKE on Polkadot exemplifies a shift towards decentralized physical infrastructure networks (DePIN) that tie real-world devices to blockchain rewards and consensus. It’s a proof-of-concept that technologies like Polkadot are ready to support high-throughput, real-world workloads that previously were considered too cumbersome for blockchains. As Polkadot continues to upgrade (with features like asynchronous backing, coretime markets, and JAM), we can expect more projects in energy, telecommunications, transportation, and beyond to adopt similar models. This convergence of blockchain with real-world data streams heralds a future where trustless data validation becomes a norm in many industries, improving transparency, security, and efficiency in processes that rely on shared data.
Conclusion
WAKE’s decision to build on Polkadot is a forward-looking bet on infrastructure that can meet the demands of global-scale, real-time data networks. Polkadot provides WAKE with a unique combination of benefits: the ability to custom-build a marine Web3 blockchain for AIS data, the throughput to handle a firehose of messages, the security of a highly decentralized validator set, and the extensibility to grow with future innovations like the JAM upgrade. In choosing Polkadot as its base layer, WAKE is not only solving a pressing industry problem (verifiable maritime tracking), but also showcasing the power of modern blockchain architectures to support real-world use cases that were previously out of reach. As WAKE progresses from Westend testnet to mainnet deployment, it will be a project to watch – a live example of how scalable, trust-minimized infrastructure can bring tamper-proof maritime intelligence to life. In the bigger picture, WAKE on Polkadot hints at how other sectors might wake up to Web3: by leveraging networks like Polkadot that offer the performance and flexibility needed to bridge the physical and digital worlds in a trustless way.
