PROFILE

Marko

During a two-month period, Marbar contributed to celestiaorg/celestia-core by building core blockchain infrastructure focused on data availability and transaction processing. He integrated Celestia-specific features such as BlobTx and IndexWrapper, enhancing block execution and state synchronization to support new transaction types and improve reliability. Using Go and Protocol Buffers, Marbar also implemented operational metrics for transaction monitoring. In the following month, he designed and delivered two complementary mempool architectures—a TTL-based priority mempool and a content-addressable transaction mempool—improving transaction prioritization, dissemination efficiency, and node configurability. The work demonstrated depth in distributed systems and backend development for scalable blockchain networks.
