이 노드의 history_mode는 "full"이며 전체 노드는 현재 체크 포인트 이전의 블록에서 블록의 헤더 및 작업 이외의 데이터를 제거합니다.

전체 모드에서 블록의 헤더 만 쿼리하는 것은 모든 수준에서 작동합니다. curl -v http://mainnet.tezos.cryptium.ch:8732/chains/main/blocks/BKrq16vch5v3iEE1hHSMENLh54vBikkmqYLDv4j7hANx6ZE3Rmb~72755/header 가 작동합니다. 불행히도 전체 모드에서 블록 작업에 대한 RPC 끝점은 현재 손상되었습니다. "전체 노드에서 가장 최근 체크 포인트 이전 블록에서 작업 데이터 쿼리 " :

현재mainnet.smartpy.io (아카이브 노드)에는 표시되지 않습니다.

편집 : rpc는 이제mainnet.smartpy.io에서도 열리고 "아카이브"가 표시됩니다.

You can call the checkpoint rpc:

http://mainnet.tezos.cryptium.ch:8732/chains/main/checkpoint

which returns

}

history_mode for this node is "full" and full nodes prune data other than block's headers and operations from blocks before the current checkpoint.

Querying only the block's header in full mode works at any level, e.g.: curl -v http://mainnet.tezos.cryptium.ch:8732/chains/main/blocks/BKrq16vch5v3iEE1hHSMENLh54vBikkmqYLDv4j7hANx6ZE3Rmb~72755/header works. Unfortunately, the RPC endpoint for block's operations in full mode is currently broken - see issue "Full node unable to query operation data from blocks prior to most recent checkpoint":

This is currently not shown for mainnet.smartpy.io (which is an archive node).

Edit: the rpc is now opened as well on mainnet.smartpy.io (and shows "archive").
