getchaintips

getchaintips Return information about all known tips in the block tree, including the main chain as well as orphaned branches. Result: [ (json array) { (json object) "height" : n, (numeric) height of the chain tip "hash" : "hex", (string) block hash of the tip "shortHash" : "hex", (string) short-derived hash of the tip header (Tensor extension) "branchlen" : n, (numeric) zero for main chain, otherwise length of branch connecting the tip to the main chain "status" : "str" (string) status of the chain, "active" for the main chain Possible values for status: 1. "invalid" This branch contains at least one invalid block 2. "headers-only" Not all blocks for this branch are available, but the headers are valid 3. "valid-headers" All blocks are available for this branch, but they were never fully validated 4. "valid-fork" This branch is not part of the active chain, but is fully validated 5. "active" This is the tip of the active main chain, which is certainly valid }, ... ] Examples: > bitcoin-cli getchaintips > curl --user myusername --data-binary '{"jsonrpc": "2.0", "id": "curltest", "method": "getchaintips", "params": []}' -H 'content-type: application/json' http://127.0.0.1:8332/
