Basics

  • London-based
  • Been around since 2015.
  • Aka Provable
  • From CoinDesk (5-3-2020):

"Provable Things announced Thursday it had successfully launched pTokens – 1:1 proxies for cryptocurrencies on other blockchains – onto the Ethereum mainnet, and that they would be fully interoperable with bitcoin (BTC) through the Bancor and Kyber integrations."

"Oraclize is a London-based cybersecurity company with a team of 9 people offering a centralised solution to blockchain oracles. They have the longest actively running and the world’s most widely adopted blockchain oracle service. While it is available on multiple blockchain platforms (Bitcoin, Ethereum, Monax, Rootstock, Corda and private networks), the majority of their customers are working on Ethereum."

Utility

Token Details

"Provable Things founder Thomas Bertani said cross-chain interoperability was the "missing link" needed to take DeFi to the next stage of adoption. pTokens, he added, would enable "liquidity [to] flow instantly and fluidly between different blockchains." Users holding value on bitcoin can now mint pBTC tokens on the ERC777 standard

Similar integrations with the Litecoin and EOS blockchains have already been successfully tested. Support for Litecoin should come online within the next few weeks, a Provable Things spokesperson said."

Oracle Method

"On-chain request, off-chain provider; example Oraclize

  1. User initiates on-chain transaction (deposit/withdraw/buy/sell/liquidate/etc.) to smart contract
  2. Smart contract submits HTTP request on-chain to oracle smart contract
  3. Off-chain centralized service picks up the HTTP request event and parses the HTTP request off-chain, receiving data
  4. Centralized approved service writes the received data back on-chain to the smart contract (the smart contract can optionally callback the initiating smart contract)"

Usage

"In production on blockchain mainnets since 2015. We have processed more than 1 millions requests to date."

  • Data only provided on request (no unnecessary data storage or gas fees)

Cons

  • Centralized service
  • Response asynchronous delay (app responsiveness)
