8/ Bottom Line
dcrtime = prove data existed, on-chain, at scale.
- Unlimited hashes, one Merkle root, one tx/hr
- Built for Politeia, available to anyone
- Inspired by OpenTimestamps
Decred is chain is a timestamping authority. $DCR
7/ Anyone Can Use It
dcrtimegui is a free web app: timestamp files with Decred blockchain.
Upload a file -> hash -> dcrtime anchors it -> timestamp proof.
Free, open, no account. Files timestamped forever.
1/ dcrtime - Decred Blockchain Timestamping - A Thread
Most chains do not have a timestamping service. Decred does.
dcrtime anchors hashes to the blockchain. One tx batches unlimited timestamps. Here is how it works.
8/ Bottom Line
Decred PoS is not Ethereum PoS:
- No BFT validator set - ticket lottery with open pool
- No quick unstake - 5-month lockup is an attack cost
- No separate governance layer - votes live in block headers
Three architectural choices that change the trust model. $DCR
7/ The Header Architecture
PoW miners produce a block, next block must include votes from the previous block.
Missing votes -> subsidy penalty. Votes say invalid -> block rejected.
Miners depend on voters to get paid. Voters depend on miners. Neither can act unilaterally.
1/ Decred PoS Is Architecturally Different - A Thread
Most PoS chains: validators take turns proposing, BFT voting decides finality.
Decred is built completely differently. Three architectural choices that make it unique.
