On December 17, Coin Metrics, a blockchain research platform, released the latest article. The operation ranking of the top ten crypto projects by crypto market value shows that among the top ten crypto projects by market value, BTC, BCH, LTC, and BSV complete nodes are synchronized, The ease of updating and maintaining is relatively simple. ETH and USDT (Omn nodes) complete nodes are easy to synchronize, update and maintain. EOS and Binance Chain nodes have the highest level of ease of synchronization and maintenance. Coin Metrics explained that EOS has a responsible model that extracts the necessary data to review too complex. At the same time, the synchronization node also needs to run an archive node with additional plugins. In addition, the large amount of EOS borrower and lender data also increases the difficulty of synchronization. Coin Metrics claims that it took more than a month to synchronize a complete archive EOS node and required a TB-level NVMe SSD computer (which already has very fast storage); Binance Chain DEX charges a certain fee, making it difficult to obtain data At the same time, it is also the only unpublished source code chain, which only provides signed binary files to possible node maintainers. Finally, Ripple and Stellar nodes failed to synchronize. Coin Metrics claims that a small number of assets (especially Ripple) require a particularly large amount of storage (tens of terabytes) so that nodes cannot be run and synchronized.
