Hardfork upgrade from blockchain sentinelhub-1 to sentinelhub-2

Set halt block height

1. Open the file ${HOME}/.sentinelhubd/config/app.toml with a text editor

2. Set the value halt-height = 901800

3. Save and close the file

4. Restart the Sentinel Hub daemon

5. Wait until the blockchain halt

Export the state

1. Verify the software version

   sentinelhubd version --long
   Note

   Commit hash must be 1aed4ffff291f6cec7e3768806bebef4e9f4442c

2. Export the Blockchain state

   HALT_HEIGHT=901800
   
   sentinelhubd export --height ${HALT_HEIGHT} > ${HOME}/${HALT_HEIGHT}.json

3. Verify the SHA256 of the JSON file

   jq -cSM '' ${HOME}/${HALT_HEIGHT}.json | sha256sum
   Note

   Exported Genesis file hash must be e519a0dbb7e7e177c72965c0f7cd8507a537548f56e696c44bd01360424137ad

Install the new software

   sentinelhub version --long
   Note

   Commit hash must be 4cd6b2bb3609b6ca86414d50216568e90b847c28

2. Migrate the exported Blockchain state

   CHAIN_ID=sentinelhub-2
   GENESIS_TIME=2021-05-29T14:30:00Z
   INITIAL_HEIGHT=901801
   
   sentinelhub migrate \
       --chain-id=${CHAIN_ID} \
       --genesis-time=${GENESIS_TIME} \
       --initial-height=${INITIAL_HEIGHT} \
       ${HALT_HEIGHT}.json > ${HOME}/genesis.json

3. Verify the SHA256 of the JSON file

   jq -cSM '' ${HOME}/genesis.json | sha256sum
   Note

   Migreated Genesis file hash must be 1dbcd7d58845b4b0696d31daafa2096bb3d729e51f8e8fa17e9e73eda1376382

Setup

       --chain-id ${CHAIN_ID}

2. Copy validator node and consensus private keys

   FROM_DIR=${HOME}/.sentinelhubd/config
   TO_DIR=${HOME}/.sentinelhub/config
   
   cp ${FROM_DIR}/node_key.json ${TO_DIR}/node_key.json
   cp ${FROM_DIR}/priv_validator_key.json ${TO_DIR}/priv_validator_key.json

3. Copy migrated Genesis file

   cp ${HOME}/genesis.json ${TO_DIR}/genesis.json

4. Set minimun gas prices

   • Open the file ${HOME}/.sentinelhub/config/app.toml
   • Go to the line which contains the field minimum-gas-prices = ""
   • Change the value to minimum-gas-prices = "0.1udvpn"
   • Save the file

5. Set peers and seeds

   • Open the file ${HOME}/.sentinelhub/config/config.toml

   • Go to the line which contains the field persistent_peers = ""

   • Insert the below node addresses
