Summary:

• Fractal Testnet beta.1 is now live (will reset and upgrade after node completes difficulty adjustment code modification).
• This update includes Ordinals inscription indexing and inscribing services.
• UniSat App, marketplace trading, and Runes support will be available next week.

Development Resources:

Blockchain Explorer:

• https://dev-fractal-explorer.unisat.io/
• The following updates are implemented in the current version:
  1. ✅ Block generation time changed from 600 seconds to 30 seconds.
  2. ✅ Halving cycle changed from 210,000 blocks to 2,100,000 blocks.
  3. Difficulty adjustment will use BCH's ASERT with a half-life of 6 hours.
  4. Blocks divisible by 3, except for the genesis block, are merge mining blocks.
  5. ✅ Genesis block unchanged, produces 50 BTC to Satoshi's address but is unspendable.
  6. ✅ In the first block after the genesis block, an amount equal to the total mining output (105 million.) will be pre-allocated to a spendable address.
  7. ✅ Starting from the second block, each block will produce 25 FB, with 8 decimal places remaining unchanged. Total mining supply: 2 * 25 * 2,100,000 = 105 million.
  • (Nodes are temporarily not open to external connections).
  • (Address transaction history is temporarily unsupported).
