Detailed Summary for Celestia EXPLAINED (Modular Blockchains Animated)
Summary generated by AI from the ICI team
[00:02] Celestia is the first modular blockchain network with customizability and scalability.
– Celestia allows for new possibilities in blockchain with Sovereign Roll-Ups.
– The founding team includes Ismail Khoffi, a previous senior engineer at Tendermint and the Interchain foundation, John Adler, founder of Fuel and previously a scalability researcher at ConsenSys, and Mustafa al-basam, the man who started it all at 16 years old.
[01:20] Mustafa learned the power of information and the importance of decentralized technologies like Bitcoin
– Mustafa founded chain space, which was later acquired by Facebook
– Mustafa obtained a PhD in blockchain scalability and wrote three papers on data availability and fraud proofs
– Mustafa’s background in these papers was instrumental in the founding of Celestia
– Celestia shifts the way we think of blockchains and provides data availability with Erasure coding and data availability sampling
[02:31] Celestia is the first modular blockchain network.
– Modular blockchains separate layers and allow developers to pick and choose the Technologies they want to use.
– Celestia allows users to choose their own virtual machine, execution environments, and settlement layers.
[04:01] Celestia provides consensus and data availability.
– Celestia acts as a blockchain with two core features: consensus and data availability.
– Consensus refers to the agreement on transaction ordering, while data availability means the transaction data is accessible to everyone.
– Celestia allows for an uninterrupted view of events and proof behind them.
– Roll-Ups can make decisions on execution environments and settlement layer using Celestia.
– Celestia doesn’t validate data but serves as a system for ordering transactions and proving data availability.
[05:18] Celestia introduces data availability sampling for scaling blockchains.
– Data availability sampling allows for faster blockchains without relying on expensive supercomputers for validation.
– Random sampling of transactions ensures that blocks are 100% encoded and published.
– The scaling properties of data availability sampling are not linear, resulting in more efficient computation.
[06:31] Data availability sampling with erasure encoding ensures secure and redundant information storage
– Data availability sampling in Celestia uses erasure encoding to protect information by adding redundancy and recovery
– Erasure encoding is similar to the technology used in CDs and satellites to recover lost or damaged information
– Erasure encoding in Celestia assigns blocks and adds backup information called parity using Reed Solomon’s algorithm
[07:47] Erasure coding provides data availability and recovery with high probability.
– Erasure coding combines polynomials to create parity blocks from original blocks.
– If data blocks and some parity blocks are lost, the lost data can be recovered using range interpolation.
– Erasure coding requires hiding over 1/4 of blocks to make the data unrecoverable.
– Data availability sampling with Erasure coding is highly reliable after a certain number of samples.
[09:00] Celestia utilizes Erasure encoding and Merkel proof to ensure data availability and prevent fraud.
– The grid format of Erasure encoding makes it easier for light clients to check for data availability.
– Clients can request to sample transactions and verify Erasure encoding and transaction data.
– Erasure encoding fraud proof is now a smaller row or column instead of the size of the entire block.
– The true dimensional eraser code format drastically lowers the barrier for data availability.
