# About Us Panthea EU is a highly trusted, reliable and secure Proof-of-Stake infrastructure provider and validator on several popular blockchains in the Cosmos Network.\ \ The Cosmos Network is a decentralized network of independent, scalable, and interoperable blockchains, creating the foundation for a new token economy. ### What is a Blockchain? A blockchain can be described as a digital ledger maintained by a set of validators that remains correct even if some of the validators (less than a third) are malicious. Each party stores a copy of the ledger on their computer and updates it according to the rules defined by the protocol when they receive blocks of transactions. The goal of blockchain technology is to make sure the ledger is correctly replicated, meaning that each honest party sees the same version of the ledger at any given moment. The main benefit of blockchain technology is the ability for parties to share a ledger without having to rely on a central authority. Blockchains are **decentralized**. The first and most famous application of blockchain technology today is Bitcoin, a decentralized currency. Beyond Bitcoin, blockchain technology has evolved to support a myriad of other applications including smart contracts, decentralized finance (DeFi), non-fungible tokens (NFTs), and more, demonstrating its flexibility and potential beyond just a digital currency system. Ethereum, for instance, extends the basic principles of blockchain to include smart contracts - self-executing contracts with the terms of the agreement directly written into lines of code. These developments signify blockchain's ability to facilitate trustless and secure transactions in a variety of contexts without intermediaries, paving the way for more transparent, efficient, and inclusive financial systems and beyond. # Provenance (HASH) Provenance is a blockchain platform designed for financial services, enabling secure and transparent transactions, asset tokenization, and streamlined processes. It offers a decentralized ledger that enhances the efficiency and transparency of financial operations, such as loan origination, trading, and asset servicing. By utilizing smart contracts, Provenance reduces costs and operational risks while ensuring compliance and data integrity. The platform supports the creation and management of digital assets, facilitating instant settlement and immutable record-keeping, making it a powerful tool for financial institutions looking to modernize their infrastructure. ## State Sync ```bash SNAP_RPC="https://provenance-rpc.panthea.eu:443" LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \ BLOCK_HEIGHT=$((LATEST_HEIGHT - 1500)); \ TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash) sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \ s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \ s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \ s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.provenanced/config/config.toml sudo systemctl stop provenanced cp $HOME/.provenanced/data/priv_validator_state.json $HOME/.provenanced/priv_validator_state.json.backup provenanced tendermint unsafe-reset-all --keep-addr-book --home "$HOME/.provenanced" mv $HOME/.provenanced/priv_validator_state.json.backup $HOME/.provenanced/data/priv_validator_state.json curl -o - -L https://valhalla.panthea.eu/snapshots/provenance-wasm.tar.lz4 | lz4 -c -d - | tar -x -C $HOME/.provenanced/data/ sudo systemctl start provenanced ``` ## Wasm only ```bash curl -o - -L https://valhalla.panthea.eu/snapshots/provenance-wasm.tar.lz4 | lz4 -c -d - | tar -x -C $HOME/.provenanced/data/ ``` ## Addrbook (Updated every 8 hours) ```bash curl -Ls https://valhalla.panthea.eu/addrbooks/provenance/addrbook.json > $HOME/.provenanced/config/addrbook.json ``` ## Genesis file ```bash curl -Ls https://valhalla.panthea.eu/genesis/provenance/genesis.json > $HOME/.provenanced/config/genesis.json ``` ## Persistent Peer ```uri aa808927715ad82be258605060c21fc5afc1cd00@provenance-peer.panthea.eu:34656 ``` ## Seed Node ```url ad3386812bb9f2fee4e9da6d9f37547afc948977@provenance-seed.panthea.eu:42656 ``` ## gRPC Endpoint provenance-grpc.panthea.eu:16780 ## RPC Endpoint ## REST/API Endpoint # Shentu (CTK) Shentu, formerly known as CertiK Chain, is a blockchain focused on security and reliability. It provides a secure infrastructure for decentralized applications (dApps) and smart contracts by incorporating built-in security features and formal verification methods. Shentu allows developers to create and audit smart contracts with enhanced security measures, ensuring that vulnerabilities are minimized. The platform's native token, $CTK, is used for staking, governance, and accessing various security services within the ecosystem. Shentu's goal is to create a trustless and secure blockchain environment, prioritizing the safety and integrity of decentralized systems. ## Snapshot (Max. 4 hours old) ```bash sudo systemctl stop shentud cp $HOME/.shentud/data/priv_validator_state.json $HOME/.shentud/priv_validator_state.json.backup rm -rf $HOME/.shentud/data curl -o - -L https://valhalla.panthea.eu/snapshots/shentu-snapshot.tar.lz4 | lz4 -c -d - | tar -x -C $HOME/.shentud mv $HOME/.shentud/priv_validator_state.json.backup $HOME/.shentud/data/priv_validator_state.json sudo systemctl start shentud ``` ## State Sync ```bash SNAP_RPC="https://shentu-rpc.panthea.eu:443" LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \ BLOCK_HEIGHT=$((LATEST_HEIGHT - 1500)); \ TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash) sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \ s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \ s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \ s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.shentud/config/config.toml sudo systemctl stop shentud cp $HOME/.shentud/data/priv_validator_state.json $HOME/.shentud/priv_validator_state.json.backup shentud tendermint unsafe-reset-all --keep-addr-book --home "$HOME/.shentud" mv $HOME/.shentud/priv_validator_state.json.backup $HOME/.shentud/data/priv_validator_state.json sudo systemctl start shentud ``` ## Addrbook (Updated every 8 hours) ```bash curl -Ls https://valhalla.panthea.eu/addrbooks/shentu/addrbook.json > $HOME/.shentud/config/addrbook.json ``` ## Genesis file ```bash curl -Ls https://valhalla.panthea.eu/genesis/shentu/genesis.json > $HOME/.shentud/config/genesis.json ``` ## Persistent Peer ```url 207c47bed435e4174844064ef3f51ca35b059de2@shentu-peer.panthea.eu:26656 ``` ## Seed Node ```url 3edd4e16b791218b623f883d04f8aa5c3ff2cca6@shentu-seed.panthea.eu:36656 ``` ## gRPC Endpoint shentu-grpc.panthea.eu:16700 ## RPC Endpoint ## REST/API Endpoint
