Bitcoin Developer Grant
Gleb Naumenko has been working on Bitcoin Core technologies since 2017. His primary focus is security, privacy and scalability of the peer-to-peer layer. He is also interested in the Lightning Network and other protocols on top of Bitcoin.
Gleb usually makes his contributions via:
- Direct changes and code review for Bitcoin Core and rust-lightning,
- Broader Bitcoin-related protocol research (usually via modelling and simulations),
- Collaborations with researchers from academic institutions, and
- Talks for the Bitcoin community as well as broader academic communities.
Gleb is most known for Erlay, the bandwidth-efficient transaction relay protocol, which allows to significantly reduce the requirements to run a full node, and enable the security increase “for free”.
He also made a number of other improvements to the Bitcoin Core peer-to-peer protocols, mainly focused on making the network more robust to attacks and spying. Lately, his attention was partially focused on the protocols on top of Bitcoin. In June 2020 Gleb published a paper which explored time-dilation attacks on the Lightning network.
In future he is planning to keep working on the security and privacy of the core software, protocol analysis, advancing Bitcoin research and bringing attention to the open problems we have.
Gleb has been awarded a Bitcoin developer grant by HDR Global Trading Limited and it is based on the open source template grant contract.
Reports by Gleb Naumenko:
In this article Gleb writes about how Bitcoin Core connects to other nodes on the network. He first provides some background about the latest default connection policy in Bitcoin Core 0.20.0, before explaining why there may be weaknesses in the current system which could make it easier for malicious actors to initiate an eclipse attack. Gleb goes on to talk about a potential more robust experimental peer selection methodology called “asmap”. Gleb then provides instructions for testing this new feature. Testing would help in ensuring the best security practices become more accessible.
