用户身份使用什么？

所有权

如何添加/撤销在OrbitDB中写入/撤销的情况下，而又不用新的ID重新创建新DB？没有3D派对服务或IPN？

是需要OrbitDB ID吗？ ORBITB/钥匙店是否需要？

否
如果程序使用obritdbaccesscontroller-在OrbitDB ID允许的情况下 - 是的 - 是的，
但这是毫无用处的 - 我们可以添加或撤销
，如上所述 - 更好的解决方案是访问控制权，随附每个数据库
，为此 - 需要自定义访问控制器
，并且既然我们有 - 为什么当Peer -ID更好时，我们会使用OrbitDB Identity，这是用户的身份，他们可以持久和备份和备份和备份他们再次从一个身份开始
IPF-IPFS节点配置JSON文件，带有PEER-ID和private-key

what to use for user identity?

ownership

program starts with discovery - users need to be able to discover dbs, like we can discover repos on github
program creates a public orbitdb database anyone can write to
users publish the dbs they want others to see to that list
and - when the write they also write name of db
if same name - how do we now that this db is actually from owner we expect? by peer-id
every message on pubsub - and also orbidb write entries - have peer-id of who posted them
so program shows name of db and peer-id of author - this way we know that that record in discovery db is exactly from that peer
and - as long as config file with peer-id and private-key is not lost - that person owns that identity

how to add/revoke writes in orbitdb without re-creating new db with new id? without 3d party services or ipns?

this is brilliant
an owner - always an owner - wants to give/take permissions
once owner creates db, program also creates a access-cotrol database - a list simply - with write permissions only to owner
other peers clone owner's db - and program also clones access-control db
program implements custom access-controller that reads from access-controller db and checks - is peer listed there? then they can write
no third party anything needed - all is already done within orbitdb
and that access controller list already decentralized and persistent and replicatable

is orbitdb id needed? is orbitb/keystore needed?

no
if program were to use ObritDBAccessController - where permissions are give by orbitdb id - then yes
but it is useless - we can add or revoke
and - as said above - the better solution is access-controll-peer-id-list-db that comes with each database
and for that - custom access-controller is needed
and since we have that - why would we make it use orbitdb identity when peer-id is much better - it is the identity of user, that they can persist and backup and they init ipfs from again
one identity - ipfs node config json file with peer-id and private-key
