🔱 Sudarshana File Storage vs. 🕸️ Arweave
1. Core Idea
Arweave: Blockweave → a blockchain-like weave where each block references both the previous block and a random earlier block, making storage “permanent” once paid.
Sudarshana: Chakra of truth → IPFS pinned content wrapped in continuous BDD verification + ECAI proofs, where permanence is guaranteed not by a weave structure but by ongoing verification and endowment-funded rewards.
---
2. Permanence Model
Arweave:
Users pay once (“endowment”) → miners commit to store the data permanently.
Sustainability is based on the assumption that storage costs fall faster than endowment interest depletes.
Sudarshana:
Users also pay an endowment (via AE contract or Lightning).
Funds drip out as continuous micro-rewards to Damage node operators for active verification + re-pinning.
Permanence = alive as long as verification runs, enforced in real time.
---
3. Verification & Proofs
Arweave: SPoRA (Succinct Proof of Random Access).
Miners must show they can retrieve a random byte from a prior block to earn rewards.
Ties mining to actual data storage.
Sudarshana: BDD + PoA Challenges.
DamageBDD issues scheduled BDD scenarios that fetch random byte ranges, check Merkle proofs, cross-gateway consistency, and log results.
Reports anchored on AE chain.
ECAI curve commitments tie the CID/merkle root to deterministic cryptographic proofs.
---
4. Consensus & Chain Integration
Arweave:
Has its own L1 consensus (blockweave).
Data is native to the chain; consensus ensures permanence.
Sudarshana:
Built on top of Aeternity smart contracts + Bitcoin anchoring.
Relies on existing blockchains for consensus; Sudarshana adds the verification + incentive overlay.
No new L1; it’s middleware on IPFS + AE/Lightning.
---
5. Incentive Model
Arweave:
Pay once, miners get ongoing rewards (inflation + endowment interest).
Mining is tied to storing data.
Sudarshana:
Pay once, funds escrowed in AE contract.
Rewards only flow when nodes prove availability in scheduled BDD runs.
Slashing if fails, re-replication bounties if availability degrades.
Stronger live-service guarantee vs. Arweave’s “pay and hope economics work out.”
---
6. Data Model & Access
Arweave:
Flat transaction model (each upload = TX).
Has permaweb layer: manifests, tags, GraphQL search, SmartWeave contracts.
Sudarshana:
IPFS under the hood (CID addressing).
Adds: BDD scenarios, Merkle proofs, gateway cross-checks.
Can build a “Permaweb-like” UX by exposing tags/manifests in the registry contract, but core focus = verification over indexing.
---
7. Security & Anti-Cheat
Arweave:
Security comes from consensus: miners who don’t store can’t mine profitably.
Still susceptible to economic failure if storage prices don’t fall as predicted.
Sudarshana:
Security comes from continuous BDD checks.
Cheats blocked by: random PoA offsets, Merkle proofs, multi-gateway checks, staking + slashing, and on-chain audit logs.
Strong cryptographic tie via ECAI points.
---
8. Philosophy
Arweave: “Permanent web” — data lives forever if you pay once, because the economics should sustain it.
Sudarshana: “Spinning truth” — data is alive only as long as verification keeps spinning. Permanence is enforced by process, not by passive economic assumption.
---
⚔️ TL;DR Contrast
Arweave = Pay once, miners promise to keep it.
Sudarshana = Pay once, but nodes must continuously prove it.
Arweave is like putting data in a vault and trusting the vault will exist forever.
Sudarshana is like keeping data in a chakra that never stops spinning — as long as the nodes keep the wheel alive, integrity is guaranteed and provable in real time.
