What Is Galaxy Heroes Coin (GHC)?

Smart contracts, or contracts for short, are at the heart of Polka Foundry blockchain. Every transaction is a contract call. Galaxy Heroes Coin blockchain supports 2 contract format JavaScript and Web Assembly. Other languages can be compiled into either JavaScript or Web Assembly before deploying to the blockchain. Under the hood, Polka Foundry blockchain uses Google’s V8 engine to execute contracts.

V8 is currently the most powerful, advanced, and mature engine for both JavaScript and Web Assembly. Galaxy Heroes Coin are contracts built into the blockchain. They handle system tasks like asset issuance and transfer, permission management, user-uploaded contract verification, and deployment, etc. Because system contracts are part of the system, they run in-process and in the same context as the system.

Galaxy Heroes Coin are contracts that developers upload to the blockchain. Transaction calls to these contracts need to be verified and wrapped, grouped for possible parallel execution before dispatching to a process pool for execution. Besides contracts, one can also deploy libraries, which can be called from other libraries or contracts but cannot be called directly from clients.

Execution

Galaxy Heroes Coin After deployment, you can send messages to the smart contract (that is, call the contract’s functions). There are basically 2 types of contract functions: ones that do not change state and ones that do. Calls that change state must be sent as transactions which require consensus on the network and thus cost some gas. Calls that do not change state is gas-free and can return instantly. Contracts submitted by users can contain dangerous code, either unintentionally (bugs) or on purpose (exploits, hacks, vandalizing, etc.). Polka Foundry blockchain performs the following measures.

Versioning

Galaxy Heroes Coin blockchain supports versioning for both contracts and libraries. A version is an integer number, starting from zero. One can deploy an update contract or library to the same address. This will increase the version by one. To avoid breaking changes, the client can specify which version of the contract it wants to communicate with (default is the latest version). A contract can also specify which version of the library it wants to load.

Light Clients

Galaxy Heroes Coin Light client support is part of the Tender mint consensus and it works seamlessly with Polka Foundry blockchain. The strong point of Tender mint light clients is that their proofs are very succinct. While a Bitcoin light client must sync chains of block headers and find the one with the most proof of work, a Tendermint light client just needs to keep up with changes to the validator set. This makes it an ideal candidate for mobile and internet-of-things use cases.

Cross-chain Communication

Because Galaxy Heroes Coin blockchain uses Tendermint Core under the hood, it is trivial to connect PolkaFoundry to Cosmos Hub (opens new window). They would decide how and when to connect to it later. Besides Cosmos, for direct cross-communication with other chains like Ethereum, EOS, Tronx, etc., corresponding 2-way bridges must be built. PolkaFoundry Blockchain’s smart contract system is capable of building this kind of bridge. Because this is not specific to Polka Foundry blockchain, this paper will not discuss it in detail.

Ones who are interested may refer to Galaxy Heroes Coin Waterloo Bridge (opens new window)and other similar solutions for reference and inspiration. The advantage is that, due to the compactness of Tendermint light client proofs, you do not need to sync Polka Foundry block headers to the other chain, just keep track of the changes of its validator set. This makes a 2-way bridge between Polka Foundry and chains like EOS very cost-effective.

Galaxy Heroes Coin One addition is that it is possible to utilize the Polka Foundry’s node gate network to relay information from one chain to others. After releasing to the main net and running stably, the governance of Polka Foundry blockchain will be transferred to Polka Foundry Foundation, a non-profit organization.

Governance

During the childhood period (first 12 months from the main net release), everyone can propose but only Galaxy Heroes Coin vote. The voting power of a validator is the sum of its own stake and the combined stake others delegate to it. The voting period is short. Part of the validator’s deposit is slashed if it does not vote in time.

After the childhood period, the Galaxy Heroes Coin enters a mature one. The voting period takes longer. Everyone can explicitly vote or delegate its stake to a validator. Changes to the blockchain are requested in the form of proposals. People must deposit a sufficient amount to back the proposal before it becomes eligible for voting.
