Zilliqa: Consensus data on Block view

UI Customizations

Regular Block Table

On the Block view page, the block table should include the following new entry:

• View: Integer field
  • Tooltip: "The iteration of the consensus round in which the block was proposed."

Quorum Certificate

Each block in Zilliqa has an associated Quorum Certificate entity containing several fields. We need a layout to display this entity in a structured and user-friendly way. The fields in the Quorum Certificate are:

• Signers: Currently, this should display as a list of integers representing validator indexes. However, future enhancements may link these integers to validator addresses. So it would become a list of addresses.
• Signature: A hex string of 194 characters (similar to a block hash, but longer).
• View: Integer field indicating the consensus round, similar in appearance to a block number.

Data example

Field	Tooltip	Example Value
View	"The view number of the quorum certificate, indicating the consensus round."	1137866
Signature	"Aggregated BLS signature representing the validators' agreement."	0xa78c7f3e07e1df963ddeda17a1e5afd97c7c8a6fc8e0616249c22a2a1cc91f8eef6073cab8ba22b50cc7b38090f1ad9109473d30f24d57858d1f28c6679b3c4deeb800e5572b5e15604596594d506d3103a44d8b707da581f1a4b82310aeecb6
Signers	"An array of integers representing the indices of validators who participated in the quorum (indicated by the cosigned bit vector)."	[0, 1, 3, 8]

Aggregate quorum certificate

Some blocks in Zilliqa have an Aggregate quorum certificate. This certificate structure is nested, requiring a clear display strategy. The fields in this entity include:

• View: Similar to the Quorum Certificate.
• Signature: Same as in the Quorum Certificate.
• Signers: Same as in the Quorum Certificate.
• Nested Quorum Certificates: A list of nested Quorum Certificates, each with fields similar to the Quorum Certificate but with an additional small integer field named Proposed by Validator.

Aggregate quorum certificate data example:

Field	Description	Example Value
View	"The view number of the aggregate quorum certificate, indicating the consensus round."	1137866
Signature	"Aggregated BLS signature representing the validators' agreement."	0x820f591cd78b29a69ba25bc85c4327fa3b0adb61a73a4f0bd943b4ab0b97e061eae9ac032d19fbfab7efb89fac2454ab0b89fea83185c0dac749ff55b0e2c21535a2b712872491577728db868d11939461a6bfde0d94d238f46b643bbe19767e
Signers	"An array of integers representing the indices of validators who participated in the quorum (indicated by the cosigned bit vector)."	[1, 2, 3, 8]
Nested Quorum Certificates	-	See example table below

Nested quorum certificates data example:

Field	Tooltip	Example Value
View	"The view number of the quorum certificate, indicating the consensus round."	1137863
Signature	"Aggregated BLS signature representing the validators' agreement."	0xa78c7f3e07e1df963ddeda17a1e5afd97c7c8a6fc8e0616249c22a2a1cc91f8eef6073cab8ba22b50cc7b38090f1ad9109473d30f24d57858d1f28c6679b3c4deeb800e5572b5e15604596594d506d3103a44d8b707da581f1a4b82310aeecb6
Signers	"An array of integers representing the indices of validators who participated in the quorum (indicated by the cosigned bit vector)."	[0, 1, 3, 8]
Proposed by Validator	"Validator index proposing the nested quorum certificate"	1
