Proof-of-Contribution (PoC) is a novel consensus mechanism that powers Gnoland. Unlike previous approaches to reach consensus in an asynchronous environment based on pure financial power (be it hash power or amount of tokens staked), Proof-of-Contribution relies on a group of Contributors to govern and operate the blockchain. According to the official Gnoland blog, there are 4 ways to become a contributor:
- Complete predefined tasks
- Complete pre-defined bounties
- Complete retroactive bounties
- Vesting style-rewards for core members
Out of these select Contributors, few are elected as Validators who have exclusive rights to verify transactions and produce blocks.
Revenue (fees) of the Gnoland blockchain is shared across Contributors, Validators, and smart contract publishers.
Gnolang is a specialized programming language designed for the creation of smart contracts, known as "realms," for the Gnoland blockchain. As an interpreted variant of the Golang language, Gnolang inherits key characteristics such as simplicity, modularity, and concurrency.
Upon submission of source code to the Gnoland Chain, the GnoVM performs an abstract syntax tree interpretation, which requires developers to provide the original source code for transparency and accountability, in contrast to the use of bytecodes on the Ethereum blockchain.
In the near future, Gnolang will incorporate concepts related to multithreading and concurrency, such as Go routines and Go channels, to enhance the development of realms on the Gnoland platform.
A realm refers to a specific instance of a smart contract that can be written in the Gnolang programming language.
Each realm has the capability to publicly export the function Render(path string) string, which performs rendering when passed a valid markdown as a parameter for the specified path. This feature allows for increased ease of use and interactivity when working with realms.
During the development and prototyping phase, developers may utilize the gno CLI tool to streamline the testing and building of realms.
Additionally, realms offer the benefit of being able to utilize packages from standard libraries, such as random, maths, avl, and much more
Prior to learning Tendermint2, it is necessary to first understand the basics of Tendermint. Tendermint is a consensus engine that allows developers to build blockchain applications in any programming language with a fast, secure, and predictable consensus algorithm. Tendermint ensures that all nodes in the network agree on the order of transactions, even in the presence of malicious nodes. You can learn more about Tendermint here.
Tendermint2 is a branch of Tendermint that aims to bring the following solutions to the table:
- Simplification of design
- Keeping total footprint small with minimal code
- Minimize external dependencies
- Modularity of components
- Completeness of software for safety
