Crypto && Coffee 013 | FATF Releases the Results of its February Meeting

Technology Recap: 


  • The bitcoin-dev mailing list heated up this week with posts regarding how a Bitcoin transaction can leak protocol usage. Full message here. 
  • Developers are starting to weigh in on Taproot versus alternatives for enabling a Merklized Abstract Syntax Tree (MAST) and Schnorr signatures. The debate is also growing around how they will actually activate these Bitcoin Improvement Proposals (BIPs).  


  • The Bitcoin ABC v0.21.0 release has been made available three months in advance of the scheduled upgrade activation on May 15th, 2020. The protocol upgrade, once activated, will enable:

  • Support for a miner-activated infrastructure funding plan 


  • There is work on a new EIP aiming to add pre-compiles to the EVM for arithmetic operations on the elliptic curve BLS12-381. Support for this curve enables interoperability with ETH2.0, ZcashFilecoin, Chia, Dfinity, Algorand, and more. This change also aids in zk-SNARK applications.  
  • In the last Ethereum AllCoreDevs call, they discussed the proposed fork schedule: 
  • Berlin: includes BLS pre-compile upgrade sometime in June 2020. This upgrade will prep for the ETH2.0 Deposit Contract.
