The evolution of blockchain.
Why blockchain is good
Cryptocurrencies use a decentralized ledger called a blockchain. Computational expenses are high but the ledger prevents double-spending of coins, and provides full transparency into all prior transactions. Trust is paramount.
Why blockchain is bad
With blockchain your account numbers, account balances, transaction history, and public keys, are always visible. The same is true of the companies that manage your wallet, and exchange your coins. Specific accounts can be targeted by anyone from small-time hackers to rogue governments. Theft is instant, irreversible, and cannot be distinguished from an "inside job". These weaknesses cannot be patched without extreme computational costs, which are already so high that they may have environmental impact.
How Gilder is different
The Gilder metaledger contains no private data, at all. There are no wallet IDs to target, no public keys to crack, and no histories to scrutinize. Transactions require minimal computation, less than what is required to load a single web page. Assets (coins) secured on the ledger become ideally suited for standard real-world financial functions such as insurance, escrow, lending, auditing, and trusteeship.
How can I participate?
The native coin of the Gilder ledger is XGL.
Units of XGL are ₲, unicode character x20b2;
These coins are on the OPL ledger now. Public release will be in 2018.
