Crypto && Coffee 059 | New ETH All-Time High 

Technology Recap:


  • As of Sunday, January 10th, 2021, it has been ~26 days since the mempool has cleared. The week of January 11th started with a full mempool and the additional increase of the difficulty adjustment. As of January 13th, the mempool sat at ~164MB covering 122 blocks.
  • Suhas Daftuar posted on the Bitcoin-Dev mailing list proposing a new BIP for a disabletx message that could be sent during connection negotiation.

The disabletx message negotiation persists for the lifetime of the connection, allowing peers to use different limits for disabled relay connections.
  • Pieter Wuille posted on the Bitcoin-Dev mailing list a draft BIP for a modified version of bech32 address encoding. The modified version, bech32m, will be used for Taproot addresses and possible future new scripts.
