If you device 5th Generation Xeon SP, you need to install additional Package

Install package for Intel 5th Generation Xeon

sudo apt-get install -y sgx-ra-service

Download Latest Version (1.0.2)

Clone repo

cd $HOME
wget https://service2.snollygoster.xyz/swisstronik/swisstronik_1.0.2_amd64.deb.zip
unzip swisstronik_1.0.2_amd64.deb.zip

Install extracted .deb package

sudo dpkg -i swisstronik_1.0.2_amd64.deb

If you found issue with libsnappy1v5, please install that package!

Install libsnappy1v5

sudo apt-get install libsnappy1v5 -y

Next, you need to copy v1.0.2_enclave.signed.so in /usr/lib to directory with already existing enclave.signed.so (default directory : $HOME/.swisstronik-enclave) file. DONT REPLACE enclave.signed.so, just copy and paste on the same DIR

Pass Remote Attestation

NOTE :

1. For update binary swisstronikd_v1.0.2 in /usr/local/lib . For updated enclave file in /usr/lib

2. For SEED_HOME environment variable has been renamed to KEYMANAGER_HOME and should point to the directory containing .keymanager (by default, this is ~/.swisstronik-enclave/.keymanager).

Let's we test request encryption keys to rpc swisstronik official, using one of this commands :

With EPID

ENCLAVE_HOME=<PATH_TO_ENCLAVE_FILE> KEYMANAGER_HOME=<PATH_TO_SECRETS_DIRECTORY> \ 
swisstronikd_v1.0.2 enclave request-epoch-keys-epid \
rpc.testnet.swisstronik.com:46789

With DCAP

ENCLAVE_HOME=<PATH_TO_ENCLAVE_FILE> KEYMANAGER_HOME=<PATH_TO_SECRETS_DIRECTORY> \ 
swisstronikd_v1.0.2 enclave request-epoch-keys-dcap \
rpc.testnet.swisstronik.com:46788

Found problem? Find here, with some solution!

• Cannot find swisstronikd binary? Download old binaries from here, and move it to /usr/local/bin

Old binaries

wget https://service2.snollygoster.xyz/swisstronik/old-binaries.zip

• If you got error libsgx_wrapper.x86_64.so copy the file from you download (old-binaries) move it to dir /usr/lib

============================================================

UPGRADE IMMEDIATELY TO LATEST BINARY (1.0.2)

After saving all binaries and dependencies, please update the configuration to the new settings:

BEFORE YOU UPRADED TO LATEST VERSION, MAKE SURE BLOCK HEIGHT ALREADY REACH TO 5430000

• Backup Backup everything again. Please ensure, that you backuped following folders:

1. .swisstronik. This is required to be able to rollback upgrade

2. .swisstronik-enclave folder and enclave.signed.so file. This is required to be able to restore the encryption key

• Download latest genesis.json Download genesis.json file for v1.0.2 version :

Latest genesis.json - for v1.0.2

wget https://service2.snollygoster.xyz/swisstronik/genesis.json

• Update Validator

  1. Backup .swisstronik/data/priv_validator_state.json, .swisstronik/config/priv_validator_key.json and .swisstronik/config/node_key.json

  2. Then run swisstronikd tendermint unsafe-reset-all --keep-addr-book to clean all state chain and also you should remove file .swisstronik/config/genesis.json.bak

  3. Replace .swisstronik/config/genesis.json with downloaded from us

  4. Update min gas prices in app.toml to correct denom. Sample command: sed -i 's/minimum-gas-prices = "7uswtr"/minimum-gas-prices = "7aswtr"/' ~/.swisstronik/config/app.toml

  5. Restore .swisstronik/config/priv_validator_key.json and .swisstronik/config/node_key.json and `priv_validator_state.json`from backup.

  6. Set halt-height in .swisstronik/config/app.toml to 0

  7. Update .service file for your validator with updated binaries. Updated binary swisstronikd_v1.0.2 by default stored in /usr/local/bin. Updated enclave file by default stored in /usr/lib.

  8. Reload daemon sudo systemctl daemon-reload

  9. Restart your validator

systemctl restart swisstronik.service && journalctl -fu swisstronik.service -o cat

NOTE: SEED_HOME env var was renamed to KEYMANAGER_HOME and should lead to directory with .keymanager (~/.swisstronik-enclave by default)
