Transforming Blockchain Data into ClarityAt Allium, we are dedicated to simplifying the complexities of blockchain data, making it accessible, accurate, and fast.The Challenge of Blockchain DataSince our inception in late 2021, we recognized that although blockchain data is publicly available, it remains notoriously difficult to comprehend and access. For instance, answering questions like “Who are the largest Ethereum token holders over time?” typically necessitates a full engineering effort to manage RPC nodes, process extensive blockchain histories, and execute intricate SQL queries.Optimization ChallengesHistorically, blockchains have been designed for efficient Writes, with less focus on Reads, complicating the extraction of data. This design prioritizes transaction speed and fault tolerance, yet it hinders reliable data retrieval.Expertise in Data Manipulation RequiredAs Tim Roughgarden, a Columbia Professor, aptly noted, “Blockchains are (virtual) computers, not databases.” This complexity, coupled with the diverse use cases and fragmented data schemas, necessitates profound domain knowledge to convert complex technical outputs into comprehensible data regarding tokens, NFTs, stablecoins, and DEXs.Our SolutionAllium streamlines this process by ingesting, sanitizing, and standardizing data from over 100 blockchains, amassing petabytes of information that grow exponentially.Join Us in Revolutionizing Blockchain DataOur mission parallels that of Google and Bloomberg in organizing vast datasets, as we strive to index blockchain data for the benefit of the industry. We are excited to support pioneers in this space and contribute to the evolution of blockchain analytics.

Join Allium: Simplifying Blockchain DataThe Challenge of Blockchain DataSince our inception in late 2021, we recognized a critical truth: blockchain data is publicly available but notoriously difficult to interpret and access. Simple inquiries, such as “Who are the largest Ethereum token holders over time?”, often necessitate a skilled engineering team to set up RPC nodes, process vast amounts of blockchain history, and execute complex SQL queries.Why Accessing Blockchain Data is ChallengingHistorically, blockchains have been designed to optimize write operations rather than read operations. This focus on enhancing transaction throughput and building robust consensus algorithms has made it increasingly difficult to extract data efficiently and reliably.Expertise Required for Blockchain Data InterpretationAs noted by Columbia Professor Tim Roughgarden, “Blockchains are (virtual) computers, not databases.” They serve as Turing machines that allow for diverse computations, leading to a myriad of data schemas tailored for various applications. Standardizing these schemas requires specialized knowledge to transform obscure technical outputs into understandable insights regarding tokens, NFTs, stablecoins, and DEXs.Allium's SolutionAt Allium, we address this complexity by ingesting, sanitizing, and standardizing blockchain data. Our extensive archive spans over 100 blockchains, amounting to petabytes of data that is rapidly expanding.A Mission to Organize Blockchain DataSimilar to how Google and Bloomberg revolutionized access to financial and web data, Allium aims to index blockchain data for universal accessibility. This endeavor supports innovators within the industry and positions us as a vital contributor to the blockchain ecosystem.

Allium: Simplifying Blockchain Data for EveryoneThe Challenge of Blockchain DataAt Allium, we recognize that while blockchain data is inherently public and free, it is often complex and challenging to access. Since our inception in late 2021, we have been dedicated to transforming the way this data is understood and utilized. For instance, answering a straightforward question like “Who are the largest Ethereum token holders over time?” typically requires a specialized engineering team to set up their own RPC nodes, process the entire blockchain history, clean and transform the data, and finally execute intricate SQL queries.Data Accessibility ChallengesThe difficulty of accessing blockchain data stems from the fact that blockchains are primarily optimized for Writes (data entry) rather than Reads (data extraction). Historically, efforts have concentrated on enhancing transaction throughput and creating scalable consensus algorithms, which has resulted in a lack of efficient and reliable data retrieval methods.Expertise in Data Parsing and InterpretationAs Tim Roughgarden, a Columbia University Professor, aptly stated, “Blockchains are (virtual) computers, not databases.” This means that they function as Turing machines, supporting a multitude of computations. The vast array of potential use cases leads to a fragmentation of data schemas, requiring extensive domain expertise to convert intricate technical outputs into accessible information on various concepts such as tokens, NFTs, stablecoins, and DEXs.Allium's SolutionAllium addresses these complexities by efficiently ingesting, sanitizing, and standardizing blockchain data. As of now, we have archived data across 100+ blockchains, amounting to petabytes of information and growing rapidly.Join Us in Revolutionizing Data AccessMuch like Google and Bloomberg revolutionized public financial and web data, Allium is on a mission to do the same for blockchain data. This is a unique opportunity in history where organizing a vast public dataset is crucial for all stakeholders in the industry.
