Transforming Blockchain Data with AlliumThe Challenge of Blockchain DataSince our inception in late 2021, our mission has been clear: to simplify and enhance the accessibility of blockchain data that, despite being public and free, remains challenging to comprehend and utilize effectively. Answering straightforward queries such as “Who are the largest holders of Ethereum tokens over time?” usually requires extensive engineering resources.Why Is Data Access Difficult?Historically, blockchains have prioritized Writes (data entry) over Reads (data retrieval), leading to inefficiencies. The focus on increasing transaction throughput and ensuring fault tolerance has left the industry with challenges in accessing data reliably and efficiently.The Need for Expertise in Blockchain DataAs noted by Tim Roughgarden, a professor at Columbia, “Blockchains are (virtual) computers, not databases.” This complexity demands specialized knowledge to convert intricate technical outputs into understandable information for various applications like tokens, NFTs, stablecoins, and DEXs.Allium’s SolutionAllium effectively streamlines this complexity by ingesting, sanitizing, and standardizing blockchain data. To date, we have archived data across over 100 blockchains, amounting to petabytes and continuing to grow.Join Our MissionJust as Google and Bloomberg organized public financial data, Allium is committed to providing the same level of organization for blockchain data. This is a crucial moment in history where indexing a vast public dataset is essential for everyone in the industry.
