On 27 June, Stellar’s official handle tweeted regarding their Stellar v11.2. core release.
Concerning this new core release, Stellar pointed out that they have successfully implemented one of the biggest challenges of implementing Quorums into the Stellar blockchain.
The official tweet from Stellar, stated:
Setting up quorums is extremely important, but also difficult. Good news, validators! We’ve just made the process much easier with #Stellar Core Release v11.2.#StellarDevelopershttps://t.co/YQvqAwbYog— Stellar (@StellarOrg) June 27, 2019
The English books tell us that Quorum is nothing but a fixed number of eligible members. Being witty enough, the Stellar team has applied the same definition to a blockchain. The technical meaning states Quorum to be a fixed number of eligible validators or nodes.
Quorum is ideal for any blockchain that requires high transaction speed and processing of private transactions within a permitted group of validators. While dealing with choosing valid Quorum Stellar faces difficulty with their consensus mechanism which is known as Byzantine Agreement Systems (BAS), additionally, BAS is not the best way to check configurations for Quorum intersection.
Through this upgrade, Stellar (v11.2) will be introducing a new mechanism to its validators called Federated Byzantine Agreement (FBA).
Before diving into this mechanism let’s understand the role of validator in the blockchain.
A blockchain validator is someone who is responsible for verifying transactions within a blockchain”.
The Stellar network, previously faced a couple of issues with the BAS mechanism, as the validation process of a byzantine node may send wrong or no message to its neighboring nodes. [Something that all BAS protocols face]
To resolve this issue, the new FBA consensus mechanism was launched. It makes things easier for Stellar validators by introducing Quorum.
The Stellar consensus mechanism mainly depends on choosing valid Quorum sets to function properly. Prior to this upgrade, the validators configured their quorum sets manually.
To remove the hassle of manual configuration, Stellar validators v11.2 has come out! Now they can check for quorum intersection seamlessly only by recognizing the subnets without disturbing the entire network.
And this new update on the Stellar core helps the validators to improve quorum set monitoring and configuration.
