GLOBAL NODE COMPARISON

NO. CompareNodes is an independent company.

Global Node Comparison (GNC) runs on AWS using Lambda / NodeJS and DynamoDB.

We know it best but we are working to add GCP and Azure.

GNC app is able to validate endpoint compatibility for networks that are EVM compatible (e.g. L2s) or similar (e.g. BSC) as well as networks in the Polkadot ecosystem (e.g. using the substrate stack). Lastly, we can process UTXO endpoints for protocols like Bitcoin/++, Litecoin etc. Aptos, Algorand, Cosmos/tendermint and others will be supported in the near future. Thus far we have used GNC with at least 98 networks.

eth_blockNumber ("EVM"), chain_getBlockHash ("Polkadot/substrate") and getblockcount ("UTXO"). We are building an advanced version with additional methods and parameters which will be supplied by the user.

For each comparison, we launch a dedicated set of 2 lambdas in each region (27 x 2 lambdas). Each lambda does one warmup request which is discarded. Lambda runs in a loop for (up to) 30 seconds and it records the durations in nanoseconds "around" the RPC call to the endpoint. Each response is a success, fail (e.g. timeout) or a 429 (too many requests). Durations around the successes are summed and counted; failures are counted and their durations are omitted; any 429 breaks the loop for that lambda immediately. All timeouts are set to 5 seconds. Upon completion, each lambda records its results to DynamoDB. Eventually, the results are aggregated and presented in the browser.

You can share the URL for the page dedicated to your results. The tables on the results page can be pasted from your browser into a Google.Sheets or similar.

GNC app is able to use public endpoints and endpoints with an API key in the URL (like Alchemy, Infura, QuickNode etc.). Right now we do NOT support header/bearer (key) authentication (like Blockdaemon) nor basic auth (like Asternodes) but these will be available in the following releases.

NO. The endpoint URL (& key) is used during the comparison run. Both are discarded and omitted from the results, except the top-level domain of the endpoint URL. Btw, If applicable, you can simply rotate the API key after you use GNC.

When you tap/click on the icon "i" you will see the IP addresses of the endpoints from the lambdas in that region. If you wish, you can look up the values to check which CDNs and data centers are used for that region by the provider of the endpoint.
