I hereby claim:

  * I am an admin of https://www.gridcoin.pl
  * I am wilkart (https://keybase.io/wilkart) on keybase.
  * I have a public key with fingerprint 8A11 EDC8 C5B2 DD7E 748E  A7F0 E74A DA06 7047 83D3

To do so, I am signing this object:

{
  "body": {
    "key": {
      "eldest_kid": "012037d3749b9edea8b0fdd3235b4dd4e71c4e27a34f84f247f324d56a0b376979f50a",
      "fingerprint": "8a11edc8c5b2dd7e748ea7f0e74ada06704783d3",
      "host": "keybase.io",
      "key_id": "e74ada06704783d3",
      "kid": "0101ecb04169170c83c9f7f1af83dc83cf675f787998d09e43f3637de562cfed8da20a",
      "uid": "8d0bf9aee8e65d7487f7b38d71b58c19",
      "username": "wilkart"
    },
    "service": {
      "hostname": "www.gridcoin.pl",
      "protocol": "https:"
    },
    "type": "web_service_binding",
    "version": 1
  },
  "ctime": 1607677539,
  "expire_in": 157680000,
  "prev": "4ccfa6686b196f95acc333fa5ce9e142500de7979100eae64dd609823f664318",
  "seqno": 77,
  "tag": "signature"
}

which yields the signature:
