Video 017: Tezos tự nâng cấp chính mình self-upgrade (nguồn Coinbase)

lesson number three how does Tasos upgrade itself tezo's is a blockchain designed for safety open participation and upgrade ability upgrades on tezo's are handled in a methodical way that allows altes token holders to have a say in the network's future other block chains sometimes struggle with upgrades they often lack clear processes for making improvements causing disagreements among stakeholders and holding back innovation in some cases the block chains can even fork creating new cryptocurrencies splitting their communities and reducing their network effects tezo's however has two features designed to help resolve these issues and incentivize innovation a formal governance process to coordinate upgrades and inflation funding the formal governance process consists of four different voting periods each period lasts about 23 days during these periods the Baker's vote on behalf of their own test tokens as well as any that have been delegated to them delegate errs can change to a new Baker at any time – to better align with their voting preferences during the first period the proposal period any tezo's Baker can submit a proposal to upgrade or amend the Tasos blockchain Baker's can then up vote their favorite proposals the most up voted proposal during this time advances to the exploration vote period in this period if the proposal receives enough support from Baker's then it advances to the testing period during the testing period a temporary test chain is created to help make sure the proposed upgrade works and is safe for the network to adopt after the testing period the proposal advances to the promotion vote period in this final voting period Baker's vote to determine if the proposal will be implemented if the proposal receives enough support then it's approved and Tasos upgrades itself automatically with the new code it becomes a part of the main Tasos chain thanks to this formal governance process in 2019 Tasos became the first blockchain to upgrade itself automatically without requiring a fork even the formal governance process itself can be upgraded over time the second tezo's feature designed to improve upgrade ability is inflation funding during the governance process bakers can propose upgrades to improve tezo's but what incentivizes them to do so developing and proposing a blockchain upgrade can be a lot of work this problem how to pay for long-term core development and upgrades is something that affects the blockchain industry as a whole and can lead to slower innovation inflation funding is designed to solve this problem to incentivize people to create proposals Tasos allows Baker's to attach invoices to their proposals if a proposal is successfully approved in the governance process then the protocol automatically Mint's the amount of tokens specified in the invoice and pays it this means that upgrading tezo's over the long term doesn't rely on altruism and external organizations to reward innovation instead developers are financially incentivized by the network itself to improve tezo's together the formal governance process and inflation funding allows us to evolve openly and methodically without Forks or splits in the community and because every stakeholder can participate in this process it's a true digital Commonwealth and it's just the start
