[BIP Draft] P2P UTXO Set Sharing

The email provides a detailed account of the challenges faced by individuals in regions with limited and unreliable internet access, particularly when trying to participate in activities that require substantial data transfer such as syncing the Bitcoin blockchain. The sender, hailing from Nigeria, describes the typical bandwidth conditions where advertised speeds for 4G broadband are up to 150Mbps for downloads and 50Mbps for uploads, but actual speeds are significantly lower. This discrepancy is exacerbated by frequent internet blackouts which further complicate data-intensive operations like full node synchronization on the Bitcoin network.

The sender discusses their personal experiences and adaptations in response to these challenges. For instance, they traveled a considerable distance to physically copy the Bitcoin data directory from a friend, highlighting the lengths to which some must go due to infrastructural inadequacies. This method, while practical, underlines the broader issue of accessibility and the reliance on less secure methods to remain part of the Bitcoin network.

Furthermore, the discussion turns to technical solutions like assumeUTXO, which offers a potential workaround by allowing users to operate based on a presumed set of unspent transaction outputs (UTXO), thus reducing the need for complete blockchain synchronization. This method is seen as beneficial in circumstances where traditional syncing is impractical, though it does come with trust trade-offs and may not encourage further innovation in improving initial blockchain download (IBD) speeds for those with better resources.

Additionally, the mention of Western cloud providers like Hetzner, which do not serve Nigeria, points to the limitations imposed by the lack of local infrastructure and services. However, the situation is reportedly improving with the emergence of native African data centers, which could provide more robust solutions for cloud-based applications and services in the future.
